There should be almost no exhaust fab except the down pipe. you want the 200r4 it has a higer first gear that this motor likes. it also has a 3rd and a 4th gear sw. these switches are used by the ECM for timing and boost. they are a must if your going to play with this. Also the only 200 trannys that have thes swithcs in them are the 86-7 BRF and the 84-5 BRQ valve bodyes Also these two trannys have specific govoners. The only other gov. worth a crapp is the monte SS one(but you still need the above valve bodys.)if you are set on a different tranny Reprogramming is a necessity. there are also good things in using a reprogramed L67 pcm w/ trac control and torque man with a 60E tranny. Also you will be happiest with a 3:73 rear up untill @350 rwhp range and a 3:42 above that What are your specific goals???
