  1. MKIII Technical
    i have a 1990 Supra turbo, its been sitting for a few years and I am trying to revive it for my senior year. The car sat for 3 years, and the battery went dead so I replaced it. After replacing it i cranked the engine over for a little however it never fired over. I went and listened to the...

    Okay so I'm new to this and before I get flamed for "not using the search button" I haven't found any topics regarding my specific question. I have an EMU black with a prewired harness connector for the stock harness. I have added a walbro 255 fuel pump and 550cc injectors i am also upgrading...

    Hello scum, not really what’s up guys. Freshly built 7mgte keeps overheating on me to the point I can only drive about 5 minutes before I have to park it, pop the hood, and let my rad fans run with key off for a couple minutes to let her cool down. I have the Mishimoto radiator setup for the Mk3...

    I don’t want any comments about 2jz-gte swaps. I just want to know exactly what other people have PROVEN will make a reliable 600hp+ 7mgte. Currently have a build in progress with clevite main and rod bearings (may have to change due to oil clearances), weisco pistons (.50mm overbore), and eagle...

    So I installed my new intake and my throttle cable doesn’t reach and ideas or longer cables

    Hi all, Can the throttle linkage on the 7M-GTE be rebuilt? Is there a kit or is a custom job that someone knows how to do? Everything works fine, but you can tell the bushings and all that are gone and there is play (like up and down) that I'm sure should be snug yet smooth. To be clear, its...

    I’m wondering what the best place to go is for my 7MGTE, my end goal is 450-500 whp. No, I don't want to go JZ. It’s not a time crunch scenario so price isn’t a huge issue, but I don’t want to pay a trillion dollars when I could pay a million. Thank you all!

    Hello everyone. So I was recently working on my car and saw this little thing spewing gas in three directions. Pretty sure its not on right or its broken. Could anyone tell me what this part is? It's located in towards the back of the engine. My cousin said its like a solenoid but I don't think...

    What's up everyone. I got a MKIII '87 7MGTE like two months ago and since its summer (and school is done) I wanted to get work done on the car. What are some recommended upgrades that are easy to do and/or are affordable? I was going to do a fuel pump/injector upgrade but I honestly don't know...

    Hi Everyone, I hate asking for help but I am going crazy with this issue. I have a 1987 supra turbo, mostly stock besides an aftermarket intercooler, exhaust and several other small modifications. The issue I am experiencing is a significant lag/hesitation/surging at low rpm. For example...
  14. MKIII FAQ
    Would anyone know the torque spec for the temp gauge sender on a 1990 mk3 turbo? I don’t want to strip it since it’s brass going into aluminum. Thanks!

    Hi everyone, I have a 1991 7MGTE Manual Supra with around 107k miles on it. A few months ago, I started to have the issue that seems to be reported here quite a bit - turn the key and I'll hear a click, but that's it. Mine is having some strange coincidences, though, so I thought i'd post in...
  16. MKIII (1986.5-1992)
    Been trying to trace this issue for awhile now. I have a consistent miss once the car starts warming up. I am currently using the 2j COP setup on 7MGTE. When cold started car idles fine, but as the car gets temp in it the miss starts. Can hear it at stop lights and such. Tach does not seem to...

    Just got a 1987 toyota supra about a month ago and right now I'm focusing on the cosmetic side of the car, one of the previous owners decided to spray plasti dip on the car smh. After that my plan is to focus on the performance of the car (will be next year or two) I know there’s multiple...

    Hi there, I’m having trouble getting my 87’ supra that I just bought running. I’ve hardwired the fuel pump as it didn’t turn on when the ignition was on and it works. I’ve tested the CPS and the igniter and those seem fine. Seems like a spark issue to me but not sure. Does anyone have any...

    Hey y'all! So I just got my '87 7MGTE from my uncle. Literally fixed up the whole car. Swapped belts, hoses, metal head with the ARP screws and a handful of other things. It has a push to start in the coin slot. So as of recent, the car starts but it really depends. In the morning it'll either...
