Hey everyone,

Its been a while since I made a build thread (cough http://www.supramania.com/forums/showthread.php?t=81005 cough) but the Supra has been a great daily driver since I did all the proper maintenance from back then. I have been hoping for something to go wrong with the original 7mGTE motor to kick off my JDM 7mGTE motor rebuild with 31k I got in 2007 sitting in the garage but no luck with that if that makes any sense. In early of 2017 I was able to find a great deal on a non running turbo manual Supra for less than the cost of a r154 manual transmission by itself so with that purchase the ball started rolling to get this rebuild going on my 87 turbo Supra. Overall the 7m I wanted is a very reliable motor with no short cuts or cheap parts put in and a power goal of between 500 to 600 whp on e85.

The current status of things as of today. The Supra is in the garage for the winter. Everything is broken in on the rebuilt motor with no problems at all and it has around 1k miles on it but everything is just at OEM power levels with all the factory parts/electronics. I still need to install the 1200cc fuel injectors, ECU Masters standalone and redo the whole engine harness with new wiring so then I can get it dyno tuned at Sound Performance.


I would also like to personally thank everyone today to over the last 10 years for all the great information this site has provided, the part sellers in the classifieds section, the build threads and those who have shared their mistakes with us to learn from. Without all this, I know this build would not have turned out as amazing as it has so far.

Changed the OEM rear speakers to OEM Pioneer speakers from 1998 Lexus LS400:




Reupholstered the armrest and bought a new shifter boot, ebrake cover and a OEM shifter:






On to some exterior mods

Removed the old rusty fog lights. Bought new used ones, clear coated them and put new yellow LED bulbs.






Had to put another rear visor on as my old one broke in half as it flew off through the dry cycle at the automatic car wash. No automatic car washes again lol:



Was waiting on parts at the time so I put one of my gs300 wheels on the Supra just to see how it looks:

Some pictures of the drivetrain conversion

Some pictures of the differential rebuild. Thanks again Piratetip for a awesome job:







Installing the differential:




New Shaft Masters aluminum r154 drivehsaft in the middle compared to OEM on the bottom and my Shaft Masters aluminum turbo automatic driveshaft on top:



Comparing the Clutch Masters FX400 to OEM:




New Drift Motion SS clutch line, lightweight steel flywheel, clutch hub assembly and fork:



Cleaned, painted and installed the pedals. Used a nickel to replace that rubber stop as they are usually worn out and ready to fall apart.

Thanks everyone. I know it's refreshing not to see that Photo Bucket hosting error as Imgur just got a new member lol.

Next, I will be testing that Drift Motion CPS magnetic mod to see if any difference is made and posting the results on here which should be this weekend if I get the package in the mail. I will be testing it on my new remain A1-Cardone CPS unit and a old CPS unit I have in my parts box. Very curious how it will turn out on both.

Available new from Toyota Japan, as far as I know. I recently got a quote from these guys: JP-Carparts.com. It was right around $100 shipped. I wanted the TRD one, but may settle for a new OEM.

As far as I know the knob is always black, but the boot was matched to the interior.

Thanks. This is the one I bought that fits a Supra and also fits a early Lexus SC300 as well. It is a small detail but the only thing I did not like is the shift pattern under the glass is not chrome like the one in the Supra but it is still very nice.

Maybe if you take that part number you might be able to find cheaper at Elmhurst Toyota or online like here:

Re: Mo Boost, Mo Power, Mo 7m : 87 Turbo Supra 7mGTE Full Rebuild + Manual Conver + M

I know I have seen a OEM tan color manual shifter in tan interior before and here is picture of a gray shifter in the middle of this page:

https://www.carthrottle.com/post/get-your-a70-supra-turbo-now-before-prices-go-bonkers/

Here is a OEM burgundy shifter as well:

https://www.google.com/search?q=sup...UICigB&biw=1600&bih=768#imgrc=-A5uzq1mSUVz4M:


But unfortunately I believe all those colors are long gone and discontinued. Even if you find a used one it will most likely be worn out.

Re: Mo Boost, Mo Power, Mo 7m : 87 Turbo Supra 7mGTE Full Rebuild + Manual Conver + M

Yeah mine has a blue shifter. Someday it might go back on if I ever get around to putting new leather on it.
New oem replacements are long gone.

Re: Mo Boost, Mo Power, Mo 7m : 87 Turbo Supra 7mGTE Full Rebuild + Manual Conver + M

Great info guys, thanks. Question though, why does the supra with 3k miles on it have a black knob and shifter boot if there is a burgundy one. My brother has an 89 with the same color scheme and has a black knob and boot also which I'm fairly certain is original. I use to have a mint 87 that iirc came with a gray knob and gray boot. I wonder if the matching knob and boot to the interior was only an 87 and 88 thing and in 89+ this was changed to black for all cars.

I just looked at pics of my 89 blue interior and it had a black knob and boot. My 91 blue interior has a black knob and boot. My guess is the color matched cars are all 86-88 model year. The google image search linked above seems to back that up as well.

The 89+ Supra's did start to loose some interior color matched pieces such as the shift knob, steering wheels, plastic steering column shrouds and it just went to a standard black color.

Just updated the complete parts list in post #1. Also got the Drift Motion CPS magnet mod installed. Did not really notice a difference with the magnet installed but the Supra already runs like new.

It's been good. I got the 1200cc fuel injectors put in and actucally been working on rewiring the new engine wiring harness yesterday and today. Went through over 225ft of wiring already. I want to do more but the weather is just barely starting to get warmer as it was still 24*F last night and the cold makes it hard to work with these new curly wires lol. I will be updating with a lot more pictures when I get it back in.

Well the weather has been warmer and more progress has been made. I got the ECU Masters standalone installed and a made a brand new engine wiring harness running sequential fuel injection and having the standalone power the stock 7m coils. I also decided to go back to the 7m coils. I also picked up a new 86.5 non-turbo Supra which I plan on transferring everything to later on.

Here is also a video of the Supra at Sound Performance running only one pull. The wastegate that was on the turbo is set for higher boost so it opens up around 23 PSI . I need a lower opening wategate so I can run pump gas so I will be back to get the tune done in July. Just for now the Supra is making 366WHP and it pulls very hard at 14 PSI (set for fuel cut until new wastegate is installed).

Here is a video of the first start:


Here is a video of the first and only 366WHP dyno pull for now:



Lets get some more pictures rolling...

Dissecting the factory engine wiring harness to see how everything is laid out. Over 2 hours removing all dried up electrical tape:


Hanging up some of the new curly wires to straighten them out:


Down to the last OEM wires on the harness:


Got a big box of all the OEM wires that came from the old engine harness:


Here is the new engine harness with around 300ft of high quality USA made high temp electrical wire. Every terminal is crimped then soldered then dielectric greased then double heat-shrinked along with braided sleeve throughout for overkill. It was made on the motor so everything is the right length:







ECU Masters standalone mounted in factory spot with new brackets made out of some old hid ballast holders:



Upgraded the fuel pump relay from a 30A to a 75A unit, heavy duty stuff here:



Went with 2 Bosch knock sensors to replace OEM knock sensors:


Huge pile of OEM electronics that are no longer needed for the ECU Masters standalone:


Mounted the 12 position AEM boost control switch:


Here is some pictures of the new 86.5 Supra:



Bonus content - Here is some other awesome pictures/projects from Sound Performance:


Foxbody Mustang with 2jz-

Great thread. I can't believe I missed it until now. Nice work on the harness. I need to do the same at some point, my 1JZ harness is a bit of a hack job. That ECU looks right at home in there. I have an AEM V1 which is a bit large for the factory location.

Thanks mobes. The newest version of the ECU Masters computer is even smaller, about 1/2 the size of this one lol. I was looking into having someone rebuild my harness but no one can get the right measurements of exactly where you want to mount everything under the hood such as the Acura fuel injector box, e85 content sensor, iat sensor, boost solenoid and a few others so it is best to make one on the vehicle. I did have to take apart a OEM harness to use for a reference in length and wire routing but the hardest thing was just to tie together the grounds, 12+ and the 5v signal wiring.

Today I got the fuel pressure sensor installed and wired up:

I wanted to stop in and give you guys a quick update. I had the Supra back at Sound Performance for the 2nd dyno tune and it made 450 WHP at 19 psi on pump gas and 540 WHP at 23 psi on e85. My original wastegate was sticking closed from the first dyno tune so we got a replacement one put in and this is where it is now. It still has plenty of room for more HP but it will need a 2nd fuel pump and a better wastegate for boost control. Here are some videos, headphones preferred for optimal experience ;)


A quick 60 MPH run on the 1st tune with 366WHP:


The final pump gas 2nd dyno tune making 450WHP at 19 psi:


The final e85 2nd dyno tune making 540WHP at 23 psi:


A quick 80 MPH run on the 2nd e85 final tune at 540WHP:

Sounds great Ryon!

How much does SP charge for tuning there?

Also how is that Diff holding up for you?
