If 200hp is all you need, you might as well save some money and get a low mileage Gen 2 (91-93) clip. XAT can source a motor and install it for you. Jarco and MR2 Warehouse are good places to find excellent swaps. Also try "rascaca" on the mr2 message board www.mr2oc.com.

Also, when budgeting for your motorswap, don't forget to budget in belts, fluids, tune up parts. Also, it's a good time for an aftermarket clutch and flywheel. I also recommend rebuilding the turbo. It's much easier to remove when the engine is out of the car. The air quality in parts of Japan is very poor and this plays havoc on the turbo. Rebuild only costs around $225.
