Oil Pressure & Temp Explained + Sandwich Install (Rebirth Ep21) 

A few tips for people that want to copy Greg's setup: 1. You need to sand / grind away the anodizing on the sandwich plate where the post extender presses against it (right under the hex feature). This is necessary to ground the oil temperature sender to the block. This step is not necessary for the oil pressure sender, because it uses a separate ground wire. 2. You will need a bias / pullup resistor to connect the oil temperature sender. Typically 2.49KΩ is used, but any resistor in that range is fine because you can specify the resistance in TunerStudio. I used 2.2KΩ. 3. Connect the oil temperature sender to an analog input pin. I used Options Port D (Analog In 1). Then connect the pullup resistor between the temperature sender signal line and Options Port H (+5V Ref). 4. In TunerStudio go to Tools > Calibrate Thermistor Tables. Select "Custom#1 Temperature Sensor". Enter the resistance value of your pullup / bias resistor. Then enter three known temperature + resistance datapoints 5. The datapoints for the VEI Systems Temperature Sender are: 32° F = 6000Ω 124° F = 578Ω 200° F = 129Ω 6. Then go to Advanced Engine > Generic Sensor Inputs, select your analog input, name the sensor, and select the "Custom#1" transformation curve.

“I can’t afford to do this twice “.... I really appreciate that line right there, unlike most other auto RU-vid channels you actually seem to give a shit about not blowing up your car. Makes the viewer feel like you’re an average guy just following his passion , not just someone pumping out vids just for the add revenue.

Watching Greg spread thread sealer is like watching a bartender give a good pour on a beer-strangely satisfying.

Absolutely LOVE this series. No other channel goes into so much detail. Thats what i love about this channel. Keep it up 👍

He is 100% correct about the temps. I wait until my Miatas lifters stop ticking, wait for my temps to rise to almost the middle, then I still drive around for 5-10mins of "warm up driving" before i even start being rough or having loads of fun, simply because tires, drive train, oil all needs time to warm up. Just taking it easy and cruising around like a BAMF for a few mins is worth it! Great video man! Love looking at that clean engine! Its so beautiful. OCD or not, doing it right is the way to go man the only wait to achieve perfection! Never cut corners on things you love. OG Homie! Greg, clearly you love Miatas, but do you have passion for other JDM machines (love for other manufactures?), If so, which ones? Do you have other hobbies /things you love to do, that you do aside from cars and driving?

First vid i ever watched on your channel and instantly subscribed. Good stuff bro. Gonna watch the earlier vids to catch up

Very informative, very good camera angles and overall videography, good stuff, keep going man

As always, great job, sir! I always enjoy your videos. Please keep up the great work.

This was a big surprise for me, good job Greg!

Just watched your bumper cut and I already love the channel 👍

I subbed because of how thorough you are on your research. Very interested to see how long the build lasts with you properly beating the piss out of the engine after doing all the safety and preventative measures you have taken.

great content as usual you need more subscribers. I hardly ever subscribe but yours is definitely worth it. as for q n a what do you love and hate most about the miata?

Hey greg, i dont coment much, but really good job on making those videos and taking the time to explain why you are doing this and not that, That miata is going to be sick

Damn greg, video quality is too freshhhh

He deserves a lot more subscribers than he has.

You spend so much time researching and planing and making these high quality videos. What are u doing for a living man?

Loving the southern hooning shirt... Respect 👌

Your videos are too good. I need more.

Hey Greg love the vids keep up the hard work, my question for the Q&A is what got you into cars and why did you pic the Miata as your main platform?

Nice chill beats bro.

My question: Besides wrenching and making sweet videos. Is there another hobby you do in your spare time? Plus I am looking forward to seeing your fan and rad setup

That is the cleanest engine I've ever seen

Boyyyyy new video

Yeah I'd keep the oil line for the turbo where it's at now and I'd run an oil cooler on that setup so you can stay nice and chilly on those hot cali days

You know you're gonna be a huge car channel soon right? Like 2 more years, a million easy

Hey Greg, love the channel and its direction. I have two questions to ask. First one is what other passions do you have besides cars and RU-vid? The other question is that would you rather use a Torsen differential from the 1.8 Miatas, or would you rather use the RX7 FC clutch type diffs for the Miata. Thanks! Your videos helped me learn my way around my 93 Miata :)

Loctite 577 is perfect for sealing these type of sensors. Always use it at work and never lets me down.

I recently lost oil pressure cause a fitting on my oil sandwich to loosen dumping all my oil on the road 🤦🏿. It was a 2 min drive around the block but good enough to practically empty the pan. The one good thing is that the engine didn't make any weird noises.

You can also add a Mocal Laminova Oil to Water Heat Exchanger. This will allow your engine to heat the oil faster by water temperature and vice versa to cool down the oil for an average viscosity

If I’m buying sensors for my car ( oil pressure sensors, temp sensors) how do I know which one or which type will communicate with megasquirt properly ??? help Greg Thanks !

This has motivated me to buy a new engine and do a full build on it

Two questions: •What is your current daily? •Are you going to change the outro music after the VVT build is finished? Its very fitting and I do like it, just curious.

Great video! Love the content! I am finishing up my Megsquirt build and like you I am installing extra sensors for maximum protection. For you oil temp sensor what voltage values are you using to ensure your values accurately display in TunerStudio?

Great job bro

Very informative content and crispy shots as always! My question is: why don't you work in the motorsport industry? Seems like you'd love it

First off, as always, thank you for taking the time on this vid. But man, I got so many questions! 1. How are you getting a ground on the oil temp sensor? Normally they ground through the housing/threads, but you're using sealant on the threads. 2. Same question about grounding, but this time about what looks like an anodized aluminum piece that's probably not going to conduct well against the block, right? 3. If you run a separate ground wire, how are you attaching it to the temp sensor? 4. I looked at the particular sensor that you ordered and it doesn't have a calibration table. How'd you configure Megasquirt? Did you just stick it in water at three known temps and measure resistance or something? You rock, thanks again for all you do, and hope your summer heat wave ain't treating you too bad!

U deserve so many more subs

Nice video! A couple of questions. Where do I have to pass the wires to enter in the cockpit? What kind of sensors (temperature and pressure) do I should buy? I drive a 1.8 NBFL Miata.

have you looked into an accusump , improved racing sells a great kit. I got one for the race car, it makes me feel safe and loved

580 like, 0 dislikes. quality content AF right here god DAMN

Good that you feed the turbo from preesure sensor port and not the sandwich plate. Oil from ports on sandwich plate is not filtered :)

i would mock up the alternator because those fittings may be in the way. it was a pita positioning the plate and still be able to use two sensors and a feed line without kinking anything

Liked this video because, well. Southern HOONING 🤘🏼

Hey Greg, why aren't you running a sandwich plate with two 1/8" npt ports and two AN ports so you can run an oil cooler? Seems to me you will get a lot more heat in your oil and coolant if you drive it moderately hard Great content though!!! :) Keep up the good work

Is a oil sandwich plate getto? I was always told not to run one, but now you make me wanna try it !

Greg, when someone buys a used miata, besides checking the things you mentioned in the video "How to buy a used Miata!" what would be the next maintenance essentials and checks that a newbie needs to go to? and why? maybe a priority list. This could be a whole new video of you going and showing where to go. This is my situation now and it might be for a few others out there. I just want to have my car fully operationala and every little part of it running good before I start doing the tunning. I feel like if I go, tune the car and destroy the transmission or other parts of the car it would be dumb.

How do u afford all that?what u do for a living besides all this? Love the channel ...best youtuber ever!

I noticed you removed the stock oil cooler. What's the plan there? Do you think the stock oil cooler is ineffective or not needed? Or are you running an external oil cooler? Also - I had a heck of a time installing that mishi sandwich plate on my 2001 VVT block - the post was too long, so the post extender could not thread far enough down onto the post to tighten the sandwich plate against the oil cooler. I ended up fabbing a spacer to place between the post extender and the sandwich plate, but the issue would have been even worse without the oil cooler in place. Thanks!!!!

Would ever you bother to build a 1.6 up like you're doing here (unlike the previous iteration)? Also, thoughts on k swaps. They're becoming pretty tempting for me lately and seem to have a ton of potential. Plus, they have a ton of valvecover real-estate for me to paint happy trees on...

My question. Pretty quick would be how much does it cost to build an engine like you are doing?

You're the best !

is there any chance you can run a sanwich plate for oil feed and return? like the ones for oil coolers, not the one you puton, or are they all the same? thanks, learned a lot from you

Where are the links to the part for the oil pressure and oil temp sensor? Thank you Greg for this very informative video!

This answered some old question and created new ones: Is it really necessary to cut that threaded rod for the filter in order to put that sandwich plate on? And why can't you still use the old oil ''cooler'' (it's a warmer actually) on there? My thought was that the OEM cooler/warmer thingy helps to get to operation temps much quicker while the new awesome Mishimoto cooler helps to keep them temps down in case of furious track use :D Because then the whole assembly of OEM-cooler+sandwich+filter would fit without the extender, wouldn't it? So my plan was OEM rod+OEM cooler+sandwichplate+filter. Yeay or nay? :D

Hi Greg, what will you be doing with supporting mods? Such as gearbox and diff? Can they withstand that much power or will you need to fabricate one?

For the Q&A: Since I'm building a supercharger build for my 1.8 VVT, I'm curious on your thoughts on superchargers, Greg. Everyone and their grandmother seem to love the turbo. It's cheaper, sounds better and gives you that kick in the pants. But do you dislike superchargers? Or is it simply that you like turbos more? Why? For what reason do you prefer one of the other? For my own sake, I like the supercharger for it's relative uniqueness (here in Sweden, I'm one of *very* few Miatas with superchargers over turbos) and the complete lack of lag and massive low down torque. It is, however, much more expensive. I could've done three turbo Miatas for the money I spent supercharging mine.

One thing you didn't show us was how you wired the oil pressure and temp sensors into megasquirt. Did you have to build any circuits to accommodate for those extra inputs? Which MS lines did you use?

I got a question for ya. When are you gona host the next socal miata meet up?!!!

Nice Video!! the filter on my car has a male end that threads into the housing on the engine.. will these universal adapters work if I reverse the extender in the middle since they're the same thread pitch? I cant find an adapter that shows an install on a filter like mine. Thanks !

@thecarpassionchannel i want todo this to my build as well for the very same reason but what exactly is the wiring for the sensors to make this work?

Another great vid as usual 👍🏽 my question... I run a non vvti 1.8 and I'm about to do a forged build I have another 1.8 to build but are the vvti advantages worth me selling the one I have and buying a vvti to build??

When the vvt project is completely done would you be interested in some kind of longer distance meet up? Like maybe Colorado or something so subscribers from the east/midwest could meet up with you and see the car in person? I'd gladly make the 12 hr drive there to see the miata and meet you!

Just installed oil temp and press sensors and calibrated them on my MS3. What thresholds have you set up? What oil temp are you reading on normal driving?

Q&A: how do you get your in-n-out burger?

I have one of these on my 2014 WRX and it hit 240 degrees f today. 90 degrees in Florida today. My coolant temp said it was only 181 on the access port

I am very new to the mx-5 (not to the channel subscribed like 5 years ago and been following everything since) But that adapter plate does it also fit the 1.6 from 1991? Got a imported miata from America here in Europe. And yes it's going to get boosted. But it will be a slow process, it already has a aftermarket ECU, the ME221.

Are you planning to make the 1.8 a full on tapatio injection?

Will the sending unit ground in the adapter? Some anodized fittings that I’ve used have to have a separate ground because they won’t ground in the anodized aluminum like they will in a block. Thanks

dear greg, im trying to build a 1.8 for a 91 chassis and also have revlimiter gauges and want my oil pressure gauge to work, when you added the aftermarket sensor to the oil sandwich, how exactly do you wire it to send signal to the ecu?

Can you please make a short tutorial video on doing 1.6 oil pressure sensor put into a 1.8 engine? I have the dummy sensor and I want the actual sensor on 1.6 and I already have the cluster from a 1.6 so I just need the pressure sender unit.

When I removed my sandwich plate the threaded post was way to long to install the adapter on my 1.8. I noticed when you removed your oil cooler your stud was also very long , but when you installed the sandwich adapter it was short. Did you cut it or change the center post? The long stud on my 1.8 will not allow the post extender to tighten down to the sandwich plate.

What’s a more better reading for oil temperature in an oil pan spacer such as the one from z1 Motorsport (for my 06 g35) or the sandwich plate like you did ??

You may have said that, but do you plan to run an oil cooler? I am currently thinking about running one, but that would mean I had to run the sandwich plate solely for the cooler and one sensor (pressure for example) an adaptor like yours from trackspeed for the turbo feed and another sensor (temp for example), wouldn't it? Or do I miss other options? :D Also, I am not sure if I really need a cooler ....

When I work on my car i'm too busy swearing and my hands are covered in gunk. How do you find the patience to operate a camera and work on the car?

Hi Greg! I have question ... are u planning adding an oil cooler?

@carpassionchannel is there a reason your not keeping the oil warmer with the sandwich plate?

Hi mate! You are competing with mishimoto support line now... So, here is the thing, I'm after a mishimoto sandwich plate that has one sensor port and 2 lines behind a thermostat in order to add an oil cooler. Problem is, that they don't list my car, they list only 1.8 mx5 and I have an early 1.6. Do you think it will fit? since you tear apart both engines on your garage... btw mishimoto support is so slow, I've asked them on Monday lol...

Do you have a write up on which sensors you used and the wiring?

Did you consider doing an FE-3/FE-DOHC turbo swap before deciding on the vvt build?

Thanks so bro it’s too helpful

One question, can you run the oil temperature sensor directly to the gauge for it or does it have to go through the ecu? Want to put in on a stock 1.6 NB wich will receive some small bolt ons and i'd like it for safety. (And my gf will also be driving the car so ye)

I am getting ready to install the turbo on my NB, where is the best place to run the coolant return line to? That's the only line I haven't figured out.

How do you know so much about cars and rebuilding engines?

greg please do a video on how to configure the sensors on MS. I have ms3pro PnP do I need a pull up resistor? Help!?

Don't blame you about the dual oil pressure gauges...I'm OCD too. lol

what if you decide to leave the oil sensor stock and use the sándwich adapter and add the vdo sensor that connects two wires in it is it works that way to lot of videos but not to much explained like yours i have 06 2.7 tiburon

What would make a 1.6 turbo with a megasquirt bog coming off of idle? Rpms drop after tipping in from idle before they come up. Otherwise the car runs fine and messing with accel enrichment hasn't done anything to fix the problem.

why miata? and what do you like on this car? It is my favourite btw :D

can you use Maga squirt to not allow ignition on cranking tell a certain oil pressure is reached?

Hey greg can u tell me did u have to change anything for engine swap or did the 1.8 hust fit the same mounts and bolt holes???

What kind of sealant are you using on the threads of the sensors on the sandwich plate?

great shit

Hi, I have the same oil temp sensor as you but am confused on how to wire it. Will any wire do ? Does it run straight to the ECU ? How does it turn it into a digital reading ? Thanks

Can you use a sandwich plate with the 1.8 na oil cooler plate still in place?

I tried a sandwich plate on my 1990 miata but could not screw on the oil filter due to clearance. Any ideas! Cool build by the way.(y)

Do you know what causes the stock oil gauge needle to raise to the middle with ON position before starting the car? Since my aem oil pressure gauge also reads low numbers so I'm not starting my car yet until I fix the issue please help thanks?

Do you have a goal to get the miata up and running by a certain date, or are you just taking your time so you don't fuck somthing up?

Q&A What do you think about euro cars like: audi, volkswagen, BMW or Volvo?

Where did you get all your knowledge from about motors, and what are your other jobs?

Do you still have the z32? If so, any chance you can bring it back after the vvt is done?
