i'm gonna buy some Pacesetter LT's with ORY. i already have the LM. i think i'm gonna go with the race style which don't have the AIR and EGR Valves on them. would i have to change any of the computer settings or what would i have to do? and would i need O2 simulators because it's a 94 A4 Z. or would it matter at all?

 

Won't matter at all.... computer is OBDI and doesn't care about the EGR
just block off the EGR with a plate behind the manifold and toss out the hot exhaust tube... the AIR system can be tossed and you just unbold the AIR pump from the front of the engine and save it and all the other pieces for a rainy day..

I assume the LT's have a bung for the stock O2 sensors so just use them and if doesn't reach get an extension fabricated..

regards

 

AIR pump is messed up anyway so i'm gonna toss it.
