WANT TO ADD SMALLER SUPERCHARGER PULLEY

newtomr2 · 05-10-2008, 12:19 AM

have an '88 supercharged mr2. the only mod i have done is had a rare TRD header with a thrush mini turbo muffler installed. i want more zip and i am told by my toyota mechanic that as far as pulleys go, the supercharger pulley would be the one to change. all i know is by installing a smaller pulley will make the supercharger spin faster thus increasing the performance. the things i don't know...where to find one, what size to get and if i can get by without doing any other mods after changing this pulley. i had one mr2 inthusiast tell me i would not have to do any mods but i needed to keep the boost below 8 or 9 pounds. i am told that a TRD supercharger pulley is the way to go but they are now extinct. can anyone HELP me???

AFAIK there never was a TRD supercharger pulley. Search for the NEVO crank pulley. That is what I ran on my 88 SC a few years ago.

hey aaron, thank you for the info. with the nevo crank pulley...is there just one size or if not what was the size you used???how much difference did it make? also, what other mods would i have to make on my stock mr2 if i went with the nevo crank pulley??the only mod i have done is a TRD exhaust and thrush mini turbo muffler. thanks, matthew

The only other mod I did was a boost gauge and an intake, basically mounted a pipe and filter in the trunk.

The NEVO is a 12-13 psi pulley. I didn't have a dyno back then, but I would have guessed a 25 hp gain.
