1990 Supra Performance mods?
 
I just bought a 90 Supra with 100,000 miles on it. It's really clean got it looked at by mechanic and it is in good shape was wondering what modifications i could put on it to up its performance. I was thinking a new exhaust and maybe an intake. Dont wanna spend more than $2000 on it any suggestions to get its performance up a bit?

1. replace the headgasket with an oem and arp head studs or metal hg with arp head studs
2. maintain the engine/ repalce old corroded vacuum hoses and coolant hoses
3. replace the turbo elbow, downpipe, cat, and catback with a 3" turbo back system
4. boost controller (on the stock ct, its commended not to go over 12 psi)

from here its all up to you. this is pretty much the limit on the stock fuel system. with this setup you will most likely hit fuel cut.
