i am going to pick up my new upd tomorrow, and i'm going to mail off the money for the 02 simms and the 216/218 535/535 114 cam, and i'm going to start working on my electric fans. my question is what other mods can i do while i'm doing all this, i already have bypassed the tb and trimmed the egr thing off...what else is there for me to do to get every little bit out of this thing? would bigger valves from stock benefit anything, or does machining have to be done to fit anything bigger than stock. thanks guys.

If you don't have headers and cool air intake, its a must. That engine needs to breath. You can also either buy a new MAF (Grenateli) or remove the screen out of the factory MAF. Too, you can grind the throttle stop so that your throttle plate will open completly.

 

have done all of that, i have shortie headers but am stepping up to long tubes in the next few weeks, as soon as i get rid of the shorties.

If you don't have ASP pullies yet, I would install those while your doing the fan install. Once the clutch fan is out, the crank pully is easy to get to.
