He should be turning about 700hp on 93 pump. He is running a 280 cam and they can't advance it very far and barely makes a difference in spool or power. Some people even disable it.
Interesting, does your friend know Shep personally or have a really good hook up? From my understanding Shep hasn't released pricing or info on the 6spd rebuilds and what parts are being replaced/reinforced. Usually when the 6spds trans go, the intermediate shaft gets all banged up and is a $1200 part to replace. Unless your friend swapped a 5spd in his car, then ignore my past couple sentences.

To the OP, if you are gunning for an Evo, stick with the 5spd. I would look for an SSL SE, or the version with the sunroof.
