    I have an 89 7mge that I got a month or two ago, and I’ve been slowly doing repairs trying to make it a daily driver. I did new intake gaskets, throttle body gasket, also did new coolant lines while I had the intake off. I replaced the fuel filter, also new plugs and wires, and new knock sensor...

Recently I had to jump my car not sure why but it was a rough start That’s for sure now I gotta leave for work I go outside and all it does is crank. It doesn’t even sound like it’s gonna start Just cranks could it be too cold out for my fuel pump...

    So I just bought an 89 Cressida with a 7mge/w58 and drove it 200 miles home. It has a couple issues… I’m super new to these motors 1. Takes a few tries to start. The motor could be warm or cold, doesn’t matter. It always takes me 3-4 tries of cranking for around 10 seconds each, and when it...

    Howdy y’all I have always loved MK3s growing up. I knew someone in my hometown when I was in high school that had a very beat up 1986 N.A. 5 speed hard top. It was silver and brown I believe. Hard to tell with the shape the paint is in. I’ve been watching as Supra prices are climbing over the...

    I have a front sump oil pan from a 7mge Cressida and I'm trying to put the 7m in my 86.5 supra and I have the old engine out of the supra and I was wondering if I can just swap over the oil pump and then I can put the mk3 7m oil pan on or do I have to buy a specific oil pan to fit the mk3...

    Hello all, I'm new here and just bought a clean 1987 Supra Mk3. I did the usual checks and the interior is beautiful, almost perfect paint 100,000 miles; but the car is still needs some work. The main issue is a "knocking" noise that only happens when the car is first turned on after sitting a...

    Hey guys, Recently while i was driving my voltage started going down and the car died right before my driveway, so i pushed it up and tested it, bad alternator. So while the alternator was bad, the brake and battery light came on while I was driving. Replaced the alternator and it was smooth...

    I have a 1986 7mge supra that struggles to start up. It cranks several times before roaring to life, and idling too high (800-1000). I suspect a vacuum leak is the source of both of these issues yet I am wondering if anyone else has dealt with these issues and found a different culprit. I have...

    Hey all, my 86 7mge randomly started to run really bad at lower RPM's (less than 2k) and barely makes any power. I think the AFM is good (it dies when I unplug it) and I recently replaced all the injectors. What confuses me is that it happened really suddenly. I got on the highway with no...

    Hello my 86.5 mk3 with the 7mge will crank, but wont start i have cams at back plate marks with crank at zero along with the first piston at tdc. I have also made sure the distributor is lined up when at tdc to drill hole on the little gear to line on the distributor housing and it is sparking...

    Hi, I'm in the process of building my 7mge+t and I'm looking to go coil on plug but I'm somewhat struggling to find information in regards to the actual coils themselves , I understand r35 coils with shorter stalks are an option especially in most kits but I'm a diy'er and like doing stuff...

    Hey I bought a knock off bee r rev limiter, I'm almost 100% the wiring is correct, I looked up a pinout for the 88 ge ECU and got the ignition and all that hooked up. This limiter looks like it's trying to do its job but it's not, is that cause it's a cheap Amazon knockoff? I'll let the video...

    Hello there, Last year I´ve bought my first Supra and after few days it broke down. Now I need to replace the crankshaft. Would anybody know about one that would fit into MK3 Supra 1987, 7MGE/7MGTE engine? Thanks for any help!

    Hey guys, so im going on a 16 hour trip in my 1986 mk3 so i wanted to install a cruise control that i had laying around. I have no idea what vacuum lines go connected to it so i took a guess and connected a vacuum line from the back of the upper intake which i circled in green & it didn’t work...

    Hey I got a 1988 with a 7mge The car has an intermittent issue where the idle fluctuates depending on the initial start up. Sometimes it will idle at 1200 rpm, misfires like crazy and has very poor fuel economy (like 6mpg) but then other timeit will have an idle surge and stalls out and 60% of...

    After a 4 month hiatus my 87 is back on the rode, kinda. I have the hood off and tried driving it to my local orielys. It started great and drove with no stuttering problems. But once i got to the auto shop i let it idle for a minute or two just to make sure every was okay and the coolant temp...

    Im in the process of throwing my 7mge back together after I went down a little rabbit hole. I ripped most of the oem intake sytem out and put it all back in. When the car is given gas the trottle cuts out completely and it almost dies. Im starting to think it could be the afm but i need some...
