I had one of these and man it was just the most rewarding car I ever drove. I've owned 3 Miata's, and 4 MR2's, the MK1 MR2 was basically a street legal Go-Kart, the smell of super old 80's car was actually something that I loved about sitting in the MK1. Gas was $4 a gallon back then, but I could put $20 in the fuel tank and drive at least all week.
That MR2 Turbo, it was a fun drive, I had a JDM 3rd Gen 3sgte with the better 540cc injectors, it was almost like
a 2/3's 2jzgte in quite a few ways. It had a .50 trim turbo kit, upgraded SMIC, big pusher and puller fans on both sides of the SMIC. I had the boost cranked up to 18lbs, an anti-torque bar from the transmission to the engine mount, TRD engine mounts, ATS axle cages, polyurethane inserts, 255 BFgoodrich drag radials on FD RX7 wheels, a cheap exhaust that made the car sound like a god damned airplane everywhere it went, that car was very loud.
I estimate on a cool day it could lay down perhaps 330whp, I dyno'd on a 100 degree day, not ideal especially given that SMIC's kind of suck on hot days, and it put down 303whp.
I stomped a few cars in it, it would spool past a lot of cars that tried to race it. Wasn't super fast, but was faster than a lot of cars out there. I never had the money to do an E85 tune, and rectify the garbage SMIC with something that cooled the intake charge better, if I dick around with those cars again, at minimum I'm getting methanol injection because SMIC's are just best on cold days they're really not the best to be using on a warm day.
