turbo housings

[fastmark]

I have 91 intercooled in my truck with the 21 cm housing. I need to know which housing is the best. A 16cm is cheap but is it enough. The 14cm seams to be the way to go, How about the wastegated 12cm? Is it to much or is there such a thing? Mark

I would recommend the 14 cm2. I have the 16 cm2 which, if on a budget, is probably the best. If you can swing one, I'd go with the 14 cm2. The 12 cm2 seems too small. The few people who I've talked to can easily get into high EGT's without towing.

My 12cm is very quick off the line til' you get to 85 mph... then if you floor it it kinda dies out,... . that's when the 16cm comes in handy. . but non-intercooled you need a 16cm for sure til' you upgrade... Greg

I had an 18cm2 and changed out to the 14cm2 wastegated model. The wastegate is locked out and I get about 25 lbs boost(max. )with "PW" injectors,1. 75 timing and 20 degree turn up on the pump(that's a very small turn-up)My EGT's are lower now that stock,even when towing a 23'Travel trailer. I believe the 12cm2 is a little "quicker" but you will have higher EGT's on the top end from what everyone else has said. I can't believe it is that much quicker though as I have boost as soon as I mash the pedal!
