Even JDM 3S-GTE are only around $2000US, some even with ECU and wiring harness. Go do some more shopping. Check Forsale here and eBay. Check MR2, Celica and Camry Forum here, many info on 3S-GTE swap. Try to get a clip, Celica AllTrac front or MR2 rear.
I think the MR2 just mount the FF engine to the back, even same tranny on the 5S-FE. For real monster torque and power, do 5S-GTE: 3S-GTE top with 5S-FE 2.2L bottom. The engine still won't rev high but you'll get so much torque you don't know what to do with it.
