I'm finally getting rid of the muffler shop crushed bent piping from my IC to the TB. I've searched and seen people say 2.25 and 2.5". I'm also running the stock drag piping from the turbo to the IC. What size is the drag piping and what size should I use. I will see boost anywhere from at least 14psi but normally 17-18 everyday and plan for 22-25psi next year. Should I run 2 or 2.25 from the turbo and 2.5" to the TB?

Thanks

 

just run the 2.25"

 

2.25 everywhere? Do I need to run 2.5 to the TB?

 

2.5 from TB to IC and 2.25 to Turbo to IC sounds good if u are gonna boost that much.

 

yeah, 2.25 everywhere...the drag charge pipe from turbo to IC is only 2"

 

I am redoing my piping (Drag piping) with all 2.5". Since my t-body is stock, and my compressor outlet is 2.5", and my intercooler endtanks are 2.5" it only makes sense to use all 2.5". You will gain a slight top end with the larger piping, not that much but everybit counts.

 

Damn I've been running the stock drag 2" from the turbo and crush bent 2.5 to the TB.
