  1. 3SGTE Swap Transmission Questions

    Common Engine Swaps and Related Discussions
    Hi, I have a 1991 MR2 that was originally NA but was engine swapped by the previous owner. I bought it when I didn't know what I should have been asking about so I have no idea if the clutch or transmission was changed with the engine, and sadly no longer have the seller's contact information...

    MKI, 84-89 NA & SC
    Hey guys. I have an 87' MR2 with a 4agze swap and i'm having some issues with the amount of smoke it puts out. It starts fine, but if you let the engine idle for awhile or give it throttle the engine starts to pour out a lot of smoke both from the exhaust, and from where the exhaust manifold...

  11. coolant leaking towards front of engine, 4A-GE

    MKI Cooling & Charging
    I just went to check an MR2 for sale and the only catch is there is a coolant leak. Its not terribly bad but I haven't found to much on what it might be on here or other forums.

  13. Gen II turbo engine studder under high speed deceleration

    MKII, 90-99 NA & Turbo
    When I accelerate quickly from 70 to 80 and back off the throttle "quickly" the engine seems to almost misfire or stumble. Accelerate and decelerate at any other lower speed is no problem at all.

    MKII, 90-99 NA & Turbo
    Hey guys, I recently bought a 92 Turbo and I love her to death but she's developed a problem. When I drive and go up a hill or press the pedal down, the engine cuts out and the check engine light turns on, and it only gives me spurts of power until I stop asking the engine for so much. This only...
