Hello, I just got my Greddy intercooler kit. It is used and needs new couplers. I have some, and Powertechperformance in Calgary can get me the sizes I need quick and cheap. So I am wondering who else has these kits for a SR20DET in a Silvia S13? I am not sure what sizes I need. What size is the compressor’s outlet? What size is the intake manifold’s inlet? I need to find this out ASAP, so any help you guys can give will really help me out alot!!!

Thanks

If you have the car, why don’t you just head on outside with a tape measure.

Each kit may have different sized piping.

Thanks tips…!

That’s what I am about to do. I just figured it is a popular kit and maybe someone on here allready knows and can save me the time. And I want to make sure I get it right. There are a couple couplers that have to change diameter between 2 pipes and I just want to get everything right the first time!!

Thanks for trying to help!

My situation is my piping is all made by me, so I can’t give you the specs for your Greddy kit. I needed a 2.75" to 2.5" coupler for TB to cold pipe. Everything else was 2.5". 4" to 3" for intake, and 2" for turbo.
