Stock Turbo w/ Aftermarket Intercooler

[nicky_322_90]

I bought a 3 inch intercooler, with piping, to use on my stock Sr20det. The problem is this, I don't know what size of reducer coupler to get for the 3" piping and the STOCK turbo. Can anyone tell me what size I need the 3" to reduce to?

did you get a new piping kit too? if you didnt then youe sidemount piping wont work, just buy some cheap ebay piping, should bolt right up, OR order a good front mount kit(GReddy, HKS, maybe even ISIS) and sell the intercooler, or order good piping and use the intercooler, and good kit should include any coupler you need

........i just re-read your post....so you got the piping too, i think the outlet of the stock turbo is 2 inch, so you probably wont find a coupler that size, just step down he piping size before the turbo, to 2.5 then a 2.5 to 2 inch coupler

The intercooler and piping are both 3", the guy I talked to at Treadstone said all I need is the reducer coupler. They have them that go from 3" to 2". I just HAVE to make SURE the stock outlet is 2" so I don't have to buy another set. If you find anything on the internet, send me a link or something, maybe you'll have better luck than I did. I really appreciate the help.

But i believe the outlet on the stock T25 is 2 inches
