  1. General Supra Forum
    Hey there, got my 1j boosting and driving better after some issues, I previously did an ATF change where it was drained and replaced with fresh ATF (Correct spec of fluid), long story short I must've overfilled/not drained all out. While I was doing some light highway pulls I noticed a small...
  2. General Supra Forum
    Recently imported a crown JZS171 to Canada, long story short it revs terrible when its cold (won't rev or misfires with a bit of a loudish bang at very low rpms) after it has idled for a bit it revs fine. Driving it is where problems continue, it wont rev past 3k rpm under load unless...
  3. MKIII (1986.5-1992)
    Sorry this is bit of a multiple question post. I'm in the process of replacing my clutch and want to know if anyone has a recommendation on brand and type? My car is a pretty much stock 1JZ GTE non VVTI with basic bolt ons. Currently I am not looking at making any major changes to increase...

  5. MKIII FAQ
    I have 1JZ GTE NON-VVTI engine. Literally start the engine and I can listen to KNOCK SOUND for 1~1.5 seconds. Currenetly, the oil pump has been replaced with a new one, and the oil strainer has also been cleaned. The vehicle does not have a separate oil pressure gauge, but the low oil pressure...
  6. MKIV (1993-1998)
    One of my cars is a stock 1994 RHD SZ automatic and the block needs a rebuild. I sourced a mostly complete 1JZ-GTE VVTI with A340, ECU, harness, etc. I'm assuming the engine, transmission came from a Soarer. What driveshaft will I need to use if I intend retain automatic with the N/A differential?
  7. MKII (1982-1986)
    As the title states, I currently have a 1986 MKII Celica Supra with a 1JZGTE swap and R154 trans. Currently running a stand alone ecu and wiring harness, but looking to go back to factory to increase reliability, and don’t need to go over 350whp anyways. Any advice on who, or where would have...

    Hey guys, I have a 1988 mk3 Supra that I recently put a 1jz vvti in with a stand-alone Maxx ecu. It is the stock single turbo but I plan to add a boost controller after I fit my new 3in exhaust. Butttt, right now I am just doing general maintenance before I put on the exhaust and boost...

    Hey guys, I have a 1988 mk3 with the jzx110 engine in it (1jz vvti single turbo) running off of a Maxx ECU. Everything is stock on this engine and I recently dyno tested it. The HP came out to about 255 and the TQ about 280. These numbers aren’t bad but obviously I would like to make them...
  10. MKIII (1986.5-1992)
    Hello, I am really in between doing either an engine rebuild on my '87 7MGTE or going the 1jz route and calling it a day. I see both sides but I am still relatively new(around 2 years now) to the supra family. For those that have rebuilt their 7M's do you regret it? For those that have...

    So I’m wanting to 2JZ GE VVTI swap my g35. I found a swap harness for a Z 1jz GTE VVTI and a ecu master black ecu. Was wondering if I can run it on a GE VVTI motor. If I can any changes I will have to make?

  14. MKIII Technical
    Hi All, My 1JZ-GTE VVTi has a valve cover crack. After some research, it looks to me like used prices are high, so I may as well go billet. I did some light googling, but I didn't recognize any of the brands and wanted to make sure that I was getting a quality product that is going to fit well...
  15. 1JZ/2JZ Swap
    I currently have a car with a 1jz vvti in it and so far its amazing. Only problem is I want to create more power. Right now i just have a big turbo some fuel injectors and an aftermarket cpu and can make around 500 on a safe tune with e85. Would it be better to push the 1jz to its max or should...

  17. MKIV Technical
    I know this might have been covered but I have had trouble trying to find listings for what the compression will end up being, I have tried to work out the comp myself but unfortunately I don't trust my own calculations on it all. I am currently building a 1.5jz na+t (vvti head - non vvti...

    I’m doing a 1jz swap on my 1988 MK3 and I just picked up a 1JZ-GTE VVT-I out of a JZX-110 and it comes stock with a single turbo. I’m trying to find an intercooler for it but all I can find is the aftermarket single turbo or the stock twin turbo intercoolers. Does anyone have any ideas on where...
