Want a good exhaust, what about turbo headers? If not, what about porting the old exhaust manifolds? Will I have to have a shop make an exhaust from scratch? Are there other parts for other applications I can get in the after market that I can make fit or use in a scratch built system?
Who does good after market computer/chip tuning?
I think I have the 4L80 in it, correct? Who should I look to for a good diesel lock up converter or tranny mods to improve durability and efficiency?
Are there ANY air intake kits for the vans? Quicker spooling, but not necessarily bigger, spooling turbos?
