Preformance Chip - 323is

[Cruzin 323is]

whats going on guys, i just joined up, i have a quick question to ask, maybe someone can help me out...

i wanna boost up some horsepower, and i was looking around and i find preformance chips for a 2.5L engine, since the 323is came with a 2.5L instead of a 2.3, would a preformance chip work for my car???

If anyone else has any suggestions on how to boost some HP's, leave a reply,
-thanx

Nope. It's a completely different engine management system. OBD I vs OBD II (on your car)

If you're looking for the extra HP that is lost tot he 323 the first and I mean FIRST place to start is the exaust. You've got a major bottleneck because the downpipes go into a single cat and all the way back via a 2.5" pipe (not sure on the size could be 2.25)

My vote is to get a custom set up that does either a 3" pipe all the way back, or the dual 2.25 inch pipe like on the other 6 cylinder 3 series. Then go for an m50 intake manifold and an OBD I conversion and you'll be set for 190 horse.
