yup that's about right, my friends 94 mr2 turbo in the pic above when he just had a apexi intake hiper catback exhaust and a manual boost controller set to 15psi he dyno'd191hp and 206tq torque kicks in at about 3k and pulls to redline almost..
i would say a S13 with SR20DET and a MR2Turbo would be a pretty good race they make about the same power, the mr2 turbo weighs about 2800lbs or 2900lbs so it's very close there too... the MR2 would have an advantage from a dead stop since they come off the line like a AWD car, on the HWY the SR would probably do better against the mr2..
SR20DET and the 3sgte are similar and not similar i love the 3sgte for the fact it's a iorn block and has the big 440injectors it can handle alot of boost, with my friends upgraded turbo and intercooler it should be fine for him to run 20lbs of boost with 116octane for passes at the dragstrip and keep it around 15 to 16psi for daily driving on 93octane..
i would say silvia's/180sxs and mr2's are definetly both in the same class of cars, of course the MR2 kinda sucks for drifting and stuff like that, and i know S13s actually have a sharper turning circle then a MR2 i thought that was, but both are great cars, i'd take a mr2 turbo in a heart beat, the 93 to 95's are the best ones to get but harder to find for sure.. the 94+mr2s have cooler brake lights almost like the round kouki brake lights on the later 180sx's..
