2.5 tech 4 engine upgrades. are there any??

Hello once again people.
Maybe somebody here can lead me in the right direction. Is there a web-site or company that makes engine upgrades or performance parts for the cutlass 2.5 tech 4 inline 4 cylinder engine?????? Much much thanks if u can help..... I checked out mantapart.com, but they specialize in the quad4 and v-6 engines......thanks.

try to find some Fiero websites. Since those cars had that motor most of those guys mod them, compared to the grand ams where people ether mod some type of quad 4 or 3x00 motor. Granted even once find them you will have a limited selection on mods you can do to the engine.
