- - What Turbo (http://gnttype.org/forums/showthread.php?t=7678)

Well, I have to admit I'm confused on how to decide what trim, A/R to get with what turbo, especially with this being a major part of the overall package. :duh:

if its mostly street driven .... get the P Trim..... either a PTE 67 or Turbonetics/CPT 66 bb... performance should be almost equal.....with possible slight advantage to PTE [b/c their garrett exhaust housing always seems to flow a lil' better].... with Cottons/Turbonetics bb - H20 cooling is optional.... with PTE - H2O cooling is a MUST. so add into cost; the addition of water coolant lines.... i had good experience with my turbonetics ball bearing, but right now the PTE unit seems to be all the "rage". PTE's customer service is 500x better than turbonetics and they are "BUICK FRIENDLY" BUT Jack Cotton has EXCELLENT customer service and he IS "BUICK FRIENDLY". Turbonetics has rebuildable cartridge. PTE/Garrett has to be replaced if it ever fails. Turbonetics/Cottons has big shaft. PTE/Garrett has small shaft. At any rate they are probably both good units and you will be happy with either. So i would buy from whoever has better customer service and price. HTH

Thanks for the advise Royal-T.

I took the plunge and ordered a Turbo today. Should be ready in 2 weeks. I got the (smaller turbo) CPT 66 ballbearing with P trim and .63 A/R exhaust. The compressor has the 4" inlet and 2.5" outlet from Cotton Performance. Talked with both Mike Litch at Full Throttle and with Jack Cotton before ordering.

From what I'm told; the PTE 67 has the newer/better compresser wheel and has more power. Jack actually sells both. The CPT 66 Turbonetics comes with a 1 year warranty and is VSR balanced. It has bb is on one side only (PTE 67 is both sides) and the water cooling is optional. Jack says I don't need water for durability or anything, but I had to order it anyway. He also says if I ordered the Q trim on the CPT 66 it would be comparable to the PTE 6776. The CPT does have the big shaft and rebuildable cartridge.

Thanks Phil, Chris, and Royal-T for the info and helping me choose. Now for the mating converter....
