Hey everyone,

Its been a while since I made a build thread but the Supra has been a great daily driver since I did all the proper maintenance from back in 2007. 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.

After 1k miles on the motor, I removed the OEM camshafts installed a set of BC 264 camshafts and set the valve shim clearance after about 100 miles of running with them installed:









On to some interior mods

Removed the factory boost gauge and installed a 12v battery gauge. Also converted the automatic RPM gauge to a manual RPM gauge with the turbo circuit board behind it:




Got the 89+ cup holder installed:




Installed a passenger floor light and modded the driverside so it is brighter as well and both take a 194 bulb:

Changed the rear OEM speakers to OEM Pioneer speakers from a 1998 Lexus LS400. They sound great:




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:

Thanks CG89. I just updated the first post with a parts list. I also got around to installing the CPS magnet mod from Drift Motion.

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:


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:

nice work, I'd like to do that to my harness in the future.

It looks like the body is in better condition, is that why you were planning on swapping everything to the 86.5?

Thanks Enraged.

The 87 that I currently have needs some body work in the rear quarter panels and by the time you spend money on rust repair, body prep and paint, a better overall condition Supra is a better choice. This 86.5 supra has 3 super small spots starting but I am going to take care of it asap at a body shop when I get it driveable again. I also keep the Supra in a garage and do not drive it in winter with the heavy salt on the roads they use around here so that will help make it last quite a bit longer.
