I recently bought a 92 lx convertible with a 2.3l inline 4 and AOD. It had been sitting 7 years( under a tree to make things worse ) in previous owners backyard. Head was rebuilt stock and intake was cleaned up along with the tank dumped/cleaned. When i got it it barely got to 30mph after about 2 minutes and took forever to get up to speed on the highway but didn't want to go that fast because struts and shocks were out. I replaced those, the ICM, ignition switch, found a few chewed wires? grounds... got it driving nicely and heard many a tale of people pulling quite a bit of HP out of these engines and little tweaks to help it along. I have come across a new header for it and the guy also has 3.73 gears, he used to race dirt track in the 2.3l group. i was wondering how much of a difference the header would make ( i had the Cats deleted straight back to muffler they were clogged too), and what else I might get to boost this car.
