for a comparrison:
my car is an 86.5, 5 speed. before i turboswapped, i raced my friend, who at that time had a '92 305ci iroc camaro. i could take him. (very, very slowly reel him in) both of our motors were very, very tired. (and i've been driving stick since i was 16, and i was 20 at the time) his camaro was his first car that was a manual. he had it for 6 months.
after that, he got another camaro. this time with a 305, TBI (throttlebody injection). i could still very slowly reel him in. that motor was as tired as the other one.
he recently swapped to a crate 350ci, and made it EFI (grafted it on from the '92 camaro's 305 in conjunction with larger injectors, different computer chip etc...) i drove it the other day, and it would DEFINATLY smoke an N/A supra. (though, i'm not N/A anymore. heh)
