G day everyone! what size intercooler piping would u recommend, would the size affect the amount of turbo lag as i have a fair bit up til about 30-40 kms/hr then it takes of then hit second and a bit more etc... Currently running high flow to3 turbo, 3 inch exhaust from turbo to tail, bov, intercooler with 2 inch piping. Any ideas what it could be? Any help be appreciated! Cheers

2 inch piping is not really big, the lag is most likely because of the hiflow...

go three inch from the throttle body to your outlet on ur cooler and try and do 2.5 to the compressor housing on ur turbo, I just did it cost me $300 bucks all up and looks crazy.

What type of pipe are you people using??? aluminium or stainless steel??? and what thickness is the actual metal???? cheers!!
