*** 2.5" or 3" DP ??? ***
I am planning to run a turbo LS/Vtec with pistons and rods (not sleeved) and hope for 350-400whp with Hondata.
SC34 turbo
Spearco FMIC
Hondata S200B
RC 550s
BLOX Mani
I was planning to run a 3" AC compliant DP with 3" cat and exhaust. But I was recently told that a 2.5" would make about the same power and that I would reach full boost sooner and that it would have more low end. And that would be better for take offs as its a daily driver.
Agree or no?

bigger downpipe and exhaust=better spool and more power

Re: (Bryson)
Ok, I am set on 3". Which sucks because I just found a slightly damaged (I have a welder to repair it) 2.5" DP for like $50....but a new 3" AC compliant one is $240...
Ok, I realize crushbend sucks...but would 3" crushbent be better than 2.5" mandrel ??? hmmm....

Re: *** 2.5" or 3" DP ??? *** (jfoster)
question for all you guys.
If the turbine housing is only 2.5 outlet why would a person need a 3inch? would the numbers really be significantly higher? Yes bigger is better but is it logical?
iv'e got a gt35r with a 2.5 outlet. my shop says that a 3inch dp really wouldnt make a difference because the turbo is only 2.5.
