You can basically make one from a ct26. There are a few kits out there.... but it is generally cheaper to do a 3sgte swap... or just sell your car and buy a turbo. I went the 3sgte swap route... and I'm very happy with it.
I did the full swap. I used a wrecked turbo for all of the parts and wiring. If you don't have at least a full clip and some mechanical knowledge, don't do it. It would probably be cheaper just to buy a turbo, although I do save about a $100 a month in insurance.
i started to buy a non turbo mr2 that was super cheap but soon relized that converting over to a turbo was going to be a real job.so i decided to spend the money and get a factory turbo car.from what i can tell the people who have done the turbo coversions seem to have many problems with them.
