rear mount turbos **PROS AND CONS** 

Cops: is it stock? Me: yes. Cops: can we look under the hood. Me: go ahead. Cops: ok sir have a good day sorry for the bothering you. Me: starts driving again. Me: Let’s off gas. Car:stustustustu Cops: turns on sirens again.

As for the water issue, you could put the intake in the trunk and create a duct to get atmospheric air to it. Create some super car type ducts in your rear quarter panel 😂

That extra piping acts as a pressure container, with good tweekin you can use the lenght to your advantage and have less lag..

Thanks for the info! I’m planning on going boost this summer too and was thinking about doing a rear mount

Thanks for the infos! Been thinking about slapping a turbo on my S197 and the rear mount idea keeps coming back to me as a cool project. Lots of people think it's dumb but I like to prove people wrong!

Love it man! You could look into putting something as simple as a metal shield an inche from the bottom of the turbo to help prevent and rain/puddles from getting sucked up

I drive a 2004 acura rl with a rear mounted turbo it looks stock I even use the stock air box my boost engages at 2500 rpm and levels out at around 6000 rpm I only run 5 lbs of boost because the engine is still stock no gapped rings no ecu just a AEM fule presser regulator, 1000cc injeter's and 2 fuel pumps it's all mechanical mostly I am making a ecu with a speeduino but it's a work in progress

Well said man, hit all the key points

Nice video bro and the quality looks great 👍🏽

Im thinking of doing rear mounted turbos on my c4 this was a great introduction for me learning the ins and outs of my soon to be build c:

One huge factor in rear and mid mount turbos is the turbo oil system. Which of course can be avoided buying an oil less turbo which you have to change the grease out every couple thousand miles and that grease is pricy as well, but if you use a turbo that requires oil, maybe a 300-600 dollar one, you'd have to run long oil lines, one to feed the turbo some oil, and one to drain the oil from the turbo to the block and use a scavenge pump to push the oil back up to the oil pan, and use check valves to avoid the turbo smoking on start up and little details and such. That's another con that can be avoided by buying an oil less turbo that runs over 1k, some 2k, which the cost of the turbo is a con on its own. Being as my entire turbonetics/custom pieced together fabbed kit cost me about $1600 without supporting mods like gauges, fueling, radiator and oil cooler, luckily since it's top mount, it's just gravity drained, but I have experience with low and mid mounts as well. Other than this, i agree with everything else, has ups and downs but in some situations definitely worth the ease of fab, budget and installation.

I've done extensive testing on my rear mount truck. It's an 01 f150 extended cab with a forged 4.6L, ported factory P-I heads, and 6-speed mt82 swapped. The turbo is right behind the cab about 1 foot above the surface of the bed. Total of 13ft of charge piping. I'm running a 62/64/14 Hx-based hybrid that I built. Max boost pressure set to 10 psi.... Using the factory exhaust (w high flow cats) my turbo would achieve max boost at about 3000 rpm. Added Turbo blanket+heat wrap to piping: 2750 rpm Replaced 3" charge piping with 2.5": 2500 rpm Ported the exhaust manifolds: No measurable difference Ceramic-coated the manifolds and exhaust piping: maybe 50 less so 2450rpm Added "stage 1" Cams basically a tow cam with more lift with gains in low end/mid range: 2300 rpm I know that I am losing top end and peak numbers by implementing some of those changes but I can tell you they aren't noticeable. What is noticeable is the spool time. Being a manual transmission I wanted spool up to be as quick as possible; that was my number one priority. Apparently I will get phenomenal improvements by switching to a ball bearing turbo but I refuse. My oiling is already a breeze since the turbo is much higher than the oil pan. This small-turbo truck is a real blast to drive. It reminds me of what it felt like to drive my old 5.0 coyote mustang mt82. I have not dyno'd the truck since I made the changes to the setup. I dyno'd it back when my turbo was reaching max boost at 3000rpm Peak power was 479 whp @ 3800rpm 531ft lbs tq @ 3300rpm If i had to guess peak torque is now reached way into the 2000's. RPM @ Peak hp has probably not changed too much

awesome video. - agree being exclusive, i have had mine 4 years now and never seen another one in South Africa

I'm glad I stumbled on this. One of my only concerns about rmt is oiling. Like scavenge pump and all that. I plan on rmt my 93 civic hatchback. Yes, I know alot ppl say it doesn't make since on a fwd. Traction isn't what I'm looking for. I want the cool factor, and to be different. Also thought about cutting a hole in my spare tire well in the trunk for the filter. Use naca ducts to feed it.

If worried about lag, go the twin charged route using a Mercedes c230 clutched supercharger. You can wire it to shut off (via pressure switch) when turbo comes online

Great video! Thanks 🙏🏽

Great video bro, subbed. I’m considering doing this on my G35 I think this is the route I’m going to take for sure

Great job! Almost to 10k!👍🍺

Friggen dope man keep it up u finna make it big

Very informative video!

Thanks mate from South Australia

I have an 01 SS, cam, rear mount. It's amazing for launching. If you tune it correctly, you can make it seamless.

I've been wanting to do a rear mount turbo for my RX8. The engine bay gets super hot as is, and turbos in the back would look sick

oh more of it. i have this idea for a Z31. everybody removes ac to do a bigger turbo and intercooler. with a rear mount. you could keep ac in engine bay.

Good job.

Con's were definitely items I have thought about already. Im still intrigued with doing this on my '06 V6 Eclipse..🤔🤫

i dont like 350s that much but i enjoy your narrative and im trying to remote mount my 2nd gen acura tl stock motor. for the same reason as you, i enjoy unique things about cars. im excited for whats to come for this z and my tl (yours will %100 be faster lol, i just wanna beat stock c5's)

Good video!

"Want to know how to pleasure a woma-" "Noo, but anyways, this is my car, and it has a turbo in it's BUTT.." I found him!😭😭😭🤣

This is especially a concern if you want to turbo your engine but you also want long tube headers. For me, I've been looking to get a GT350 for a while now and recently I've been interested in Kooks long tube headers for the 5.2 Voodoo. At the same time I've been looking into how to turbo the GT350 with long tubes installed. *UPDATE February 2023:* After coming across your video and doing all the digging I've been doing for a while, I was considering going for rear-mount twin turbos, plus a supercharger to take care of the lag, but now I'm looking at short-tube headers, twin turbos, and no supercharger.

Plan on using it on my sc400

Add a centrifugal with a clutch, run a bypass intake system with a throttle body. Now your turbo setup has NO lag and will come on much quicker

Been watching a few videos on the build and i enjoy the content! I bought a beater sn95 v6 mustang that i want to rear mount turbo when i upgrade the turbo on my galant vr4 to a holset hx35

I know I’m a year late but this really helped me make my decision thanks for video bro 👍🏼

I want to do this on my 2002 civic

With a rear mount would it change the whole exhaust setup? Just got a tomei and i would rather not lose it lol

Did you need a tune after doing this

fellow ct driver woot! we got the best mix of "driving" roads up here... I mean tracks in mexico

Wow you have a mature audience. Surprised there aren't "put it in the rear" comments 🤣. Good info man. Subbed and liked my fellow CT brother 👌

1: lag is highly subjective - personally mine comes in around 3300 rpm and goes through to 8000 , when I change gears its in the band continuously. dont see how that's a bad thing?

2013 express 2500. Doing a mid undermount in place of the third cat. Welding in a T4 flange right under the side cargo door. Tons of space between the frame and drive shaft. Should be very inconspicuous.

Great 💯💯💯💯

Turbo setup on an Acura RL ka9 I would love to see this

A single exhaust wouldv'e been less materials/welding and less heat loss, though maybe you didn't have room for a larger diameter pipe? Have you considered wrapping the exhaust to keep heat in? And for those of us with a bit more room under there, an air-to-water intercooler under the back seat floor would reduce travel (not to mention increase the stealthiness).

I have rear mounted twins in a G.cherokee srt8 2012 and it hits boost at 3k rpm and its like you said "when the boost hits it hist strong"

Thanks for content, im wrinting from poland. Here rear mount turbo ist popular. Turbocharge modifications are very popular, but it is just in the front of the car. Great posibility for me also to learn english from u in the enjoyment way ! ( i have toyota yaris 1.5 106 HP. Very nice car, considering weight of the car its very fast. I woud like to make turbo to this car. Rear mount turbo sounds amazing ! i ii go that way parhapse. )

I'd love to do this with a VQ35 Elgrand

I like how your cons turn into pros lol

I watched a video dyno testing different pipe lengths The result was that length of the exhaust to the turbo does effect lag somewhat BUT the length of the charge pipe does not increase lag any significant amount I'm sure if it was 100 feet long it would but 15 feet or so have so little effect it is not worth thinking about

リアのリモートマウントターボに関して興味があったので、参考になりました。アップロードありがとうございます。ターボラグに関しては、改善される部分があるならまた知りたいです。

One of the thing is with the long pipes , is when you shift. You do not have as much pressure drop inbetween . So the initial spool lag is a very small price to pay , for keeping the boost up between shifts. The rear mount allso is less harsh on your turbo as it won't get as hot. However i would still say that on a car that allready sits low.. that can be a problem. Now , depending on the car , if its say.. a 4 jugger, I would rather look for 2 small turbo Than a large one. Cyl 1 and 2 , and 2and 4 paired. The long tubes will even out the pressure waves a lot better. Than with the small turbos you can mount them higher. Many Times its cheaper to aim for a pair of smaller turbos Than a large single unit. And many Times small turbos can get a lot higher boost. Potentially you can even regain the initial spool lag , while enjoying the benefit of the less spool loss between shifts. With the 2 small turbo approach you may verry well not need the intercooler. Saves space. Allso you can crossfeed , the turbo that gets exhaust of cyl 1 and 2 , can boost cyl 3 and 4. Its far less complicated to make a manifold with proper dimensions thatway. Volumetric efficiency can and does varry between cylinders , if you flowbech a head , you will see the deviation can be up 10% or even more. This helps resolving that issue , and while you will have less peak power , you will have a better curve. From performance stand point peak values mean nothing. Power under the curve is indeed what tells the story.

Rear mount twin turbo no more lag

On my rear mount c5 corvette would 250f oil return line work or will oil get hotter it has 2feet of an line first then into the line I speak of

All you have to do is make a turbo box. I know you don’t understand what it is but think about it for a few minutes and you’ll make one and I’ll be the fastest and you won’t have any lag.

“Really cool spool inside the car” *shows dyno clip* 😂

You gotta move that clock behind ya, it blends with your hair and makes ya look funny. Like a cartoon haircut :) Also, thank you, super cool topic.

Seems like a grat idea to add cheap top end to my 370z, my car seem to beat v8's 1/4 mile but from a roll of 75mph they eat my Z

Dude is staring down my soull

Ct hell ya

I wonder if the back pressure is lower with a rear mount so you could run a larger cam.

True if you can look under my hood, there is no space whatsoever to fit any sort of Turbocharger. It’s just full of engine Also you can hide your turbocharger so your car doesn’t look turbo’s in anyway

Just built a rear mount turbo system on my Porsche 928 ( the V8 Porsche ) There is ZERO room for it under the hood so rear is the way to go.

A snorkel on the turbo inlet would solve the water problems, right? I live in a flood prone area, so this rear mount idea might be about to get the can from me.. lol Thankfully I watched this vid. Thanks ;)

are those connecticut plates?!

I gave you a like just for acknowledging the straight piped VQ not sounding good. I’ve got a Mark VIII and there is nobody in the community after 28 years that has found a way to mount a turbo near the engine. Rear mount seems to be the way

I want to do a rear mount on my S14, sounds crazy right?

How much power are you making? What psi?

does anyone know if i can install a turbo in a 328xi but in the back cuz in the front ion got space

Is it kinda unsafe on how low the turbo and its sucking in debris? I rarely see them have intakes.

yeah wow what are the odds you stumble onto a rear mount turbo 350z build from your home turf. wild. would love to ask a few more in depth questions, getting into a turbo z build myself.

What about oil return???

What do you do for oil supply and return Do you use oil Pump and separate oil tank?

i have a S54 with velocity stacks so i have literally no air intake so i’m tryna learn how to add air. obviously nitrous but i thought i’d watch this just incase i have some power i could use back there some how lol

I did like and ring bell

Lol just saw ur car on insta and had to find out how u did it👍💯

I really want to know how many feet of oil lines do you need

I'm stuck between a rear mount or a sidewinder style crossing the entire engine and have the inlet through a quarter vent

Can this be run on an mqb platform? Mk7 gti or R would be unstoppable with a twin turbo setup , is20 or is38 up front and a big ole ar70 at the rear .

Sorry for the long comment 😊 Hey sir new subscriber here. Just trying to see if i can do rear mount exhaust to my 2000 Toyota Camry 3.0 V6. I couldn’t see or find any exhaust manifold that is already build so idk if this is the best for my car. Plus i have an idea where i can change the car from stock pipe then to another exhaust with turbo 😊. I would like to have my car to be a project can then it will be a unique in some way, That a family car\sedan can be a beast. Please let me know if this is possible. Thank you 🙏🏽 Problem I’m thinking rn is snow and rain. A good rubber cover will be great

Hey bub..I did a rear mount on my g37..lol you ain't kidding it sounds bad without resonators.what resonator did you go with I have a vibrant right off the y and it still sounds pretty bad..

So do you have to run a pump to supply oil?

I was thinking about doing a rear mounted turbo for my Q but $5k seems like a bit much. Do you know if a kit from a 350 or g37 would swap over?

One Con would be its easily stolen a sawzall and 1 minute of cutting like the guys who were stealing peoples catalytic converters in parking lots

It's a mess but it does fix a lot off reliability problems

I’m watching this like imma get a turbo soon 😭😭

If you get water in it itll probably blow the turbo up before it touches the engine

To be honest I really don't care too much about turbo lag in fact I think it's kind of fun waiting for boost to hit then feeling it start to floor you into the seat, however the reason I'm watching this video is because I've had a really bold idea in my head that I have to do now which is cutting into my trunk in my Miata and making a turbo that pokes out the trunk facing forwards with two entrys leading to the front side of the trunk almost by the doors, too crazy of an idea? Cause I'm kind of obsessed with the thought now

what size turbo you running

For guy who came hear just to listen to the sound 5:18 5:30 7:01

Strong car to complete run way on the raod staffing. Like play turbo charger and recharge money. Sart o.

Ct gang

oh shit, CT plates

i want this on my 370z

You just feel the boost lag

Having a trubo in the rear bottom get rusted with rain and dirt and then have problems? I think It wont last long.

Hydrolocking....just extend the inlet plumbing to a higher location-- shucks you can run your intake to your roof if you want

A boosted N/A miata sounds wrong😂

Turbo lag is awesome!

Lag can be caused by alot of factors. Turbo size and piping can play a massive part
