If you want a setup that will last year after year after year.

Get a HEALTHY LS motor and do your maintence work to it. Then put a basic T3T4 on about 10psi and take it to a respectable tuner(Matt Shue (sohc mshue), Patrick w/ MRD, Shad Sawyer at Accuracy, InlinePro, John Savage @ Hybrid)

I have a friend who has a LS setup that has been boosted for 3 years now.

Another, bought his hatchback with a setup going on 6 years.

Then, you have Mike. Who has a b20 that will not die. I think he's going on 3 years on really high boost(upper teens)
