This is my 7MGE Mk3 Toyota Supra. 

Thanks for reaching out man! Yeah I cannot believe how much some of these cars are going for. I was contemplating selling the car and I'm glad I decided to just hang onto it. Ive seen some 1989s going for upwards of 50-60k and in terrible condition. With my dad being the original owner it should have stayed in better condition but unfortunately with time and actually driving the car, things wear out and just get old. Oh the standalone has already been worth the money. I will do a whole video of when I send it out to get tuned (hopefully soon). I won't be even be close to utilizing all the features the ecumasters has to offer. I first purchased the DIY auto standalone and it was a waste of money and time. I was surprised at how easy it has been getting all the sensors and stuff wired in with this ecumaster. I'd love to see some pics of your car. follow me on my new instagram account supraluver and message me some pics. I just started to post pictures of mine and will also use that to document my build process. thanks again for reaching out man! best of luck on your build. Hit me up if you run into any issues.

Thanks man! I appreciate it. I personally like the walk through stuff too. I will pump out some more videos and give more in depth info on my setup. I want to just keep it real and more personal. Thanks again for the comment and the sub man!

Thanks I appreciate it! I will keep them coming for sure!

Thank you! We need more supras out there!

Thanks man! I really appreciate it!

Same . This got me so motivated to work on mine .

Thanks man! Keep it up man! We need more of these cars on the streets. It's such a fun car to own and it's always turning heads!

Thanks for checking out the channel man! Get that thing out on the road asap!

Thanks man! I really appreciate it! I'm glad you found my channel! I'm always looking for ideas for new content. I will do a video of the install for the turbo taillights. It's pretty easy but there are a few little tricks that make the install go smooth. Thanks again for the sub!

Same happy to find it and follow all mk3 builds save the 7m!!

Oh nice! You should totally do it! I've been really happy with my setup!

Thanks man! Yeah it works surprisingly well. Thanks for the sub! I have some plans for some good upcoming videos.

Absolutely! Thanks for watching and supporting the channel. More videos to come!

Thanks man! I appreciate it

Thank you! I definitely will! Hopefully I can get some more videos out really soon! Hit me up if you ever have any questions.

Awesome! Good decision! You won't regret it. I ran the hks mhg for a while and decided to switch over to the cometic gasket. Saved some money and the quality in my opinion was a little better.

@@mainstreambuilds sweet i'm glad i decided to go with the cometic gasket too!

@@nolan1812 yeah it's great quality. I'd suggest their full gasket set too. Pretty inexpensive and comes with all the replacement gaskets you need for a full rebuild.

I’m on the same mission

Keep me posted! It can always be a mystery with these cars ha.

Thanks for checking out the video! If you get your hands on one, don't let it go!

Yes! Keep the 7m alive! No but seriously they are great motors. I've pushed mine pretty hard and it hasn't given me a bunch of problems. Yeah it's a built bottom end and of course a metal head gasket with ARP head studs, but honestly I'm happy with the motor and don't have any intentions on swapping it out. Keep up the work man and thanks for watching the vids!

@Jumpin through Hoopes funny thing is I spun a crank bearing back in 2016... it's been drifting and pushed hard even with a little knock. My friends tell me to swap the 2j but I keep telling them that the 7m just won't die and if that's the case it deserves to stay in the car

@ae86mia Haha that is awesome! Yeah I spun a bearing a while back and figured it was gonna blow and it never did so I decided to do a full rebuild and make it better and stronger. I've considered getting another 7m to do another build.

and what are your HP goals?

@@deonghee5473 thanks man! I will definitely be posting more. I'm looking for around 500-600. I think I should be able to achieve that goal with what I've done with the motor.

Thanks man!

Thanks! More to come!

Haha thanks for the feedback man! Keep goin on those projects! We need more of these cars on the road. Haha yeah I noticed the ummm and uhhh as well. Haven't done a video in a while so I was uhhhh ummming a lot. Hopefully my videos get better as I make more.

Sweet! Glad you stumbled across my channel! Keep me posted on your build and if you have any questions feel free to message me!

Nice dude! Look forward to seeing the progression. Let me know if you have any questions!

Will do man! Actually editing a video as we speak.

Thank you!

Will do man! Thanks for checking out the channel.

Thanks man!

Dude thanks for sharing your story man! Unfortunately as you have experienced, these cars are getting harder to find and Unfortunately most of them are in horrible condition and have been left outside to rot away. I'm glad to hear you are working on getting it back to the condition it should be in! As for the rough idling issue, I'd start with the simple stuff. Check the spark plugs, distributor, spark plu wires, boots...etc. check the spark plug galley and see if the valve covers have leaked oil into the spark plug holes. Check the distributor cap for cracks, look at the rotor and see if the contacts are worn out (easy to replace). When I had a misfiring issue similar to yours, my valves were burned up and causing similar rpm issues. Hopefully yours is something simple like I listed. Check those little things first and hit me up if its still having issues. I've been stoked hearing from all these other guys about their Supras and the progress they have made with them. It's a pretty awesome community and everyone is so willing to help out. I appreciate your feedback and I will continue to post videos. Thanks again man!

hey man how's the car been?

Sorry it's been so long my man! Hopefully all is well and your able to cruise around. I'd be more than happy to make a list for you. I'm sure with how much time has passed you might have already done some research on your own. Let me know if you still need this info and I can do a short video. These motors are actually pretty fun to tinker with and might seem a little complex but they are very simple. Congrats on the purchase! You will not be disappointed.

Thanks man! I really appreciate the feedback. I agree with you as far as the lack of mk3 supra content on RU-vid. I hope my videos are informative and help.

@@mainstreambuilds yea man you’re the only one I know of that explains everything thoroughly . I literally was looking for some content today to get motivated to work on the Mk3 and I came across your Channel. Glad I did hehe , good look with everything man.

Thank you!

That's the plan. That cap is just temporary. I will be making an AN line going from the valve cover back to the block. I will eventually do a trigger wheel and a coil over plug setup. Curious to see what the stock distributor limits are.

@@mainstreambuilds sounds good lmk if you have any trigger questions.

@@TheMotoxxx87 what trigger wheel and coils would you recommend for the ecumasters

Oh man he is super lucky! These cars are becoming more and more rare. The three piece spoiler looks really good on the car. My supra was a base model and didn't come with a spoiler at all, so it was a good addition. Yeah the distributor takes up a lot of space and limits my ability to tune. Hopefully I can do away with it soon. Don't hesitate to message me if you guys have any questions about the car.

@@mainstreambuilds thank you, I appreciate it and I'm sure my son will also!

I keep tossing the idea around with going 1 or 2j, but then I think why? It's a great power plant. Honestly, any engine will need a little work to produce some good power. It's a simple motor, strong, and sounds good!

@@mainstreambuilds can’t forget the torque lol I completely agree

Thanks for checking out the vid. I've been through several different types. I'm currently running royal purple but will be switching to valvoline on my next change.

Since I ended up going with forged internals, it wasn't necessary to add oil squirters. I was actually talking to a guy the other day about overall costs. I saved a bunch of money by doing all the fab stuff myself, but I'd say overall, I'm probably 8-10k.

Unfortunately they are getting harder to find everywhere.

Yeah I've been slacking on the uploads and haven't given a recent update on this. I decided to bag the megasquirt and went with the ecumaster EMU classic. I finished wiring all the inputs and ran into an issue with the ignition signal. I got the adapter harness from ecumaster and I guess the wiring isn't correct so I've been needing to figure that out. So far it's been super easy to work with and I would recommend it. Another guy I know is running 500hp on his 7m with the ecumaster. I will try to do an update video on this soon.

Haha yep that was me! I'm always down to meet up man!

@@mainstreambuilds where’s the best place to get in touch

@@GroovyTrout do you have instagram?

Thanks man! And thanks for checking out my channel. The intake manifold is an XS powersports plenum welded to the 7m runners. The plenum kit is for a 2jzge. It worked out perfect, looks and sounds amazing.

@@mainstreambuilds my bad, I meant what exhaust manifold haha

@Nick McDermott haha everyone asks about the intake manifold so I just assumed. We tig welded the manifold using weld els from treadstoneperformance.com it's a T3 manifold so I'm sure I'm a little limited on power, but it gets the job done. Its fitted with a 38mm wastegate, but that will be upgraded eventually.

I actually learned it's not ideal to just block that off. I did another video where I use a -10AN push lock fitting and run the hose down to the block.

@@mainstreambuilds thanks for the update, I ended up going 1JZ vvti and truly regret selling my 7MGTE instead of building it but have buddy’s out here in Texas that still run the 7M.. I’ll check out that other video!

@JSXECO I thought about going that route as well. I'm glad I built my 7M. Great learning experience and have had a ton of fun in the process. I actually just dropped the car off to the tuner tonight so I will be doing an update video very soon!

Yep. Currently in the works. Just got my hall sensors and had a few extra trigger wheels made. Hopefully I can get it all done very soon.

So both my seats are stiff back (don't recline). I used the corbeau solid brackets. Once I did my roll cage I couldn't slide my seats back and forth. Corbeau sells the brackets specifically for our cars. I can do a short video talking about them if you are interested.

@@mainstreambuilds I was hoping you had a different bracket because I bought a set of Corbeau RRX’s not too long ago with the Corbeau sliders and brackets but it made me sit too high. Even without the sliders I didn’t sit right. I was going to buy another set of seat brackets from a different manufacturer but after looking at it, there can’t be much of a difference with another brand either. I’m guessing the seats possibly play a role in seating position as well. It would be nice to see how yours is mounted though. 👍

@@shuexiong2620 I have the fx1s and I had the same issue. They would sit way too high. The non-sliding brackets are a lot lower but they are fixed and won't move. The brackets definitely have enough material to drill the holes forward or back to adjust the seat if needed. I will do a video on it for ya. I've had other people asking about them too.

That's awesome! I've toyed with the idea of swapping motors but the 7m is a decent motor and can hold some good power with a little work. My machine shop told me that the factory 7m (turbo) rods are plenty strong for decent power. My plans were 500ish and the shop was certain the rods could hold it. Pistons on the other hand not so much.

Dude thanks for reaching out! Yeah live promachine. I will continue to use them. They also did a 4g63 for me years ago. As for the supra I'm all about the 7m but that's just me. If you have promachine deck the head and block to run a metal headgasket with ARP studs will hold together no problem. I'd maybe look into some forged internals for some added reliability. I did wiseco 84mm pistons strapped to some eagle H beam rods.

@mainstreambuilds I've built over 50 engines. I actually build turbos for a living. Just sold my 535whp 92 galant vr4. Bought a 05 is300 I'm going to build to a gte spec. Are you running emu from ecu masters?

@richardwilliams9815 oh that's rad! I had a 2dr mitsubishi mirage with a 4g63. It was a blast. Yeah I'm running the emu classic. It's sort of on a stand still until the weather warms up a little more and I find the motivation haha. It's super close right now I'm just slightly off on timing and need to check it again. Other than that everything seems to be working pretty well.

@@mainstreambuilds that's awesome. We are selling her evo 9 to fund all of this. Probably tear the engine out next month and start going on it.

@@richardwilliams9815 oh sweet! Keep me posted. Feel free to hit me up anytime if you have questions.

Thank you! No dyno numbers yet. Still working on ironing out all the wiring issues. I'm planning on around 600hp. More videos to come.

So I havent had to repin anything on my actual harness. All the cutting and splicing is done on the pnp adapter and ecumasters has done a great job with showing you how to add sensors and how to test everything on the ecumasters tuning software. If you do need to move the jumper wires, ecumasters provides great documentation on how to do it. I made sure to get the pnp for the ge (yellow connector not the grey) I haven't gotten it tuned yet but so far everything seems to be working properly through the tuning software. I've added intake air sensor, Mac valve for boost control, marlin crawler transmission speed sensor (for launch control), wired in a wide band 02 sensor, and a fuel pressure sensor. I should be getting it tuned very soon and I can give you guys some feedback.

I will do a video on my ecumasters setup. Hopefully that will give everyone a better idea. I'd definitely recommend it. Great unit for a decent price. I'm no genius when it comes to electronics and I was able to figure this out. Ecumasters has uploaded a ton of very well done videos on RU-vid which give step by step instructions.

@@mainstreambuilds Ok thanks for the info. It definitely seems like the best route short of building a custom harness for any other standalone. I’m also tempted to keep my distributor and coil like you have, just curious what the power limits will be before the coil will need to be upgraded. Make sure to post videos whenever you get it tuned too!

@@_Bonez12 yeah you shouldn't need to cut anything besides the pnp. I was in the same boat as you. I even bought a separate used harness just in case but didn't end up using it. The guy tuning my car said the distributor will definitely limit the HP but it should get me around the 500hp mark I'm looking for. I will definitely keep you posted. Worse comes to worse I will drop some coin and get a trigger wheel and do a coil over plug setup.

I've always loved this car. I'm 33 years old now and I remember my dad dropping me off at school in "the supra". I will try and keep this car in my family as long as possible. I still joke with my wife about how much attention this car gets. She experienced it first hand when I was stopped at the gas station and the kid wanted pictures and videos and kept saying "I can't believe I'm seeing this". His reaction made it all worth it. Hopefully you can keep your supra in your family for a very long time.

It actually works pretty well. Low boost and 550cc injectors, it seems pretty happy. I will eventually run a trigger wheel setup with coil over plugs just so it's more efficient, but I've been running it on stock electronics for a while and haven't had any issues.

I will be doing another video soon on how to turbo the 7m. Hopefully I can crank that out soon. As for the timing belt issue, if there is no internal damage from the belt breaking and pistons hitting valves. If all is good you could reset timing and throw in another timing belt. I would pull the spark plugs and crank the engine over by hand and see if it seizes or locks up during the rotation. The last thing you want is a catastrophic failure.

@@mainstreambuilds Thanks! I'm new to the car sphere but want to get into it as a project car. I do have some mechanical know how and have friends who are professional mechanics. Is there and online group or something for the mk3 supra I could join to learn more about this car?

@CaptainAwsome73 oh very nice. These cars are relatively simple to work on. You could always scroll through supra forums and get some good info there. Some of the info can be pretty old but still worth scrolling through.

Also I saw a guy on facebook market selling a 7mgte built block and I was thinking about buying it. Do you think I should?

I’m only aiming for about 320hp

It really comes down to how much you are willing to spend. A built 7mgte would obviously be better than a stock 7mge. If you are going to turbo the GE I would start out with building a decent foundation. Headgasket will most likely be your main issue. The factory headgaskets and head bolts aren't sufficient enough for boost. I'd look at maybe getting block and head resurfaced and run a metal headgasket with arp studs. Unfortunately I learned the hard way and kept fixing little bits here and there when I should have just pulled the motor out and installed a metal headgasket, studs, forged rods and pistons, and a shimmed oil pump.

It can definitely be done, it just needs a little work 320 isn't insane, but it is roughly 100hp more than factory. Doesn't seem like a lot but it can take some work to get there. I hope you do it! I love hearing people experimenting with the 7M and making it what it should be! Keep me posted.

1992-1995 toyota camry 4 cylinder.

My model did not come with ABS. I think driftmotion.com has an ABS delete kit.

is it the 7mgte? and how has it been? what should i know before starting. gonna start building mine this month

@@Confestus its going great! Making 352whp and 496nm torque, running healthy on a pretty basic setup. Hasn't given me much trouble to be honest, if you have any troble with your build contact me! Glad to hear you are starting a great project like this car is!

Awesome! I'm all ears man! Hit me up on instagram messenger @supraluver

Sorry man didn't see your message. I snagged mine off ebay. I made sure it was decent quality. The xs powersports plenum will accommodate a 4 bolt 90mm throttle body. I think mine is the OBX billet 90mm body that works with the older toyota throttle position sensor.

Thanks for sharing man! That's awesome! So to me it sounds like some new brake rotors might be needed. I'd also check the brake master cylinder and even the slave cylinder. It may have a small leak in the brake system from it sitting. I'd bleed the system and see if that fixes your issues. As for the rattling that could be a wheel bearing which isn't too difficult to replace. I personally would get that stuff sorted out before throwing performance stuff at it. If you have the money and time I'd start with a metal head gasket and ARP head studs. The engine will require some machining so the gasket completely seals. The head and block will need to be resurfaced in order for this to work. This process will be a good base to start with. The 7MGTE/GE are notorious for blowing headgaskets and can cause some major damage when they fail. You could also do some simple things such as replacing the mass air flow sensor with the Lexus mass air flow sensor, do the is300 coil pack conversion, and going with slightly larger fuel injectors. The CT26 turbo is great but very limited when it comes to increasing boost. You could get the CT26 that has been modified to flow a little more air. You could also do an exhaust with a larger downpipe and even a slightly larger intercooler. These cars have a lot of potential the hardest part is figuring out where to start. Hope this helps steer you in the right direction.

@@mainstreambuilds thanks for all this information. Im 21 and it looks like ill be dumping a fair amount of money until im satisfied. Please dont disappear because you are one of the few 7mgte youtubers that i look forward to watching and learning

@@keven6691 thanks man I really appreciate it!! I will for sure continue making videos!

in other words, you got any parts that you think I could turbo this on the cheap end? I cant really weld an intake manifold but i can drill into the oil pan and such

I'm actually planning on doing a video on this soon when I go to swap out turbos. It's not super involved. I had the bottom end built to support the boost and not huck a rod, cometic metal headgasket, arp head studs, wiseco pistons, eagle rods, and arp main and rod bolts.

@@mainstreambuilds I saw that in the video, I just gotta keep saving up but soon I'm gonna get there!

@Crispified98 I wanted a good base to build on. The 7M can definitely hold the power with a little work. In my opinion it's worth building. Like 1j and 2js the 7ms are now going up in proce quite a bit and worth hanging on to.

I've heard of other people having this issue as well. I haven't experienced this personally, but I wonder if is making the car run rich so the 02 sensor is telling the ecu to kill power. Do you have the factory fuel pressure regulator and fuel damper?

@@mainstreambuilds yes I have a factory regulator and fuel rail

@@mainstreambuilds I noticed that the cam angle sensor had these cheap crimp on connectors so I replaced those and soldered the wires and it seemed to remedy the random dying out a little but it’ll occasionally come back but it completely fixed the occasional misfire i was having

Lucky! Don't let go of it! As for advice I'd figure out what you want to do with the car. Do you want it for a few around town car, drift car, drag car? That will help with pointing you in the right direction for what power plant would be best. The possibilities are endless, however parts are getting harder to find and expensive. Try to find what you need and get building! These cars are so much fun and pretty easy to work on.

I definitely contemplated doing the swap myself but I wanted to try and keep it "original". I definitely want to turn mine up more. Keep me posted on what you do!

@@mainstreambuilds for sure will, i have another project though. for yours, has it been reliable? are parts cheap?

@lucioucz oh I super content with my 7M. It holds great power and I haven't had to throw a ton of money at it. I got the block and head machined a few years ago and haven't had any issues. The forged internals didn't cost an arm and a leg either. In my opinion it's a great motor to learn on.

I was being dumb and red lining it a lot because I thought it sounded cool ha.

@@mainstreambuilds gotcha lol

Factory oil pump that has been shimmed to increase the pressure.

Thanks man! I plan on doing another one with all the updates. This video was one of my first ones and it wasn't my best haha.

Everyone kinda has their own opinions when it comes to this topic. A lot of people will say the 1jz is far more reliable. I've driven my supra from Utah to Nevada several times and the only issue I had was my AC compressor went out. Other than that the car ran flawlessly. I've also seen a 1jz supra over heat and stop running. It had to be towed to the next town. In my opinion both motors are great. I'd for sure have the 7m block decked and head resurfaced and throw in a metal headgasket with ARP studs. I had this done many years ago and drove the supra as a daily for a while with no issues. Whenever I get asked this question I usually respond with "what is your goal for the car?". Depending on what you want to do with the car you may need some deep pockets. I put quite a bit of money in my car but I enjoy it and drive the s*** out of it.

@@mainstreambuilds ah I see, thanks for sharing your experience :D to be honest i love A70 and im having a plan to bought one, the only problems that i had right now was umm you know the engine itself 7M that giving me a doubts, and many people owning A70 mostly swap the 7M with 1 or 2JZ engine, could you gave me some advice? maybe a guide about purchasing A70? :D

@@mainstreambuilds i'm seriously fallin love with A70 supra but doesn't know how to bought the good conditions A70, Anyway love your videos :)

@@sonyaafterall33 thanks! I will try and be better about posting videos!

Naaa. If anything it might be a little on the small side. I have another dual ball bearing turbo with a larger turbine housing I may throw on eventually. The holset I have now is pretty limited and will max out fairly quickly.

This is a one of a kind home built. 2jzge ffim bolt on for the Lexus is300 (usdm) we welded the 7m cast runners onto the intake plenum and ported it.

@@mainstreambuilds thanks dude!!! And where did you get your throttle from?

@@arne8837 you bet man! I got just a generic 90mm billet body from ebay.

Yeah pretty funny

Yes! Very true. Slap a turbo on it and have fun! People get too caught up in all the turbo vs non-turbo stuff. If it makes turbo noises and brings happiness then goal accomplished!

@@mainstreambuilds because people are gonna remove the stock turbo anyway as well

@@kaybevang536 that's so true. First thing my buddy did on his 1j was pull the stock turbo and ma if old before he even started the swap.

@@mainstreambuilds my buddies Lexus IS the USDM Altezza with the all motor version of the 2J it’s similar

Are you able to direct message me on instagram?

Yeah I don’t have any of those platforms sorry

This is a custom intake. 2jzgte plenum welded to the 7m runners.
