Smog is due soon, and I’m tired of pouring money into the stock motor. I’m open to all engine + transmission options; stock gearbox is weaksauce too.
A few ideas:
- Toyota 2GR V6 engine with E153 gearbox. Been done many times before and it’s a big, modern NA motor.
- Honda K24 & Civic Si transmission. Also well-documented & reliable, could be cheaper than the 2GR.
- Toyota RAV4 EV full powertrain swap. (Lol) Uses the same mounting hardware as the 2GR, so it should fit in the MR2 just fine. Also would still be a “same-manufacturer powertrain” for autocross class purposes.
Oppo, what’re your suggestions? At the end of the day, I just want something reliable.
