looking to make a custom intake for my gsr using a Bpi velocity stack with a K&N filter. Now im looking for some 3" piping to make it but im not sure if anyone has any suggestions on where to pick some up. Im not sure what angles i need to make it work with my gsr intake manifold, so if anyone could chime in and help out that would be great. Expecially the people who have done this before.

 

Get 3" diameter PVC sewer pipe. It is thin wall and light weight. You can find many PVC elbows and simply glue the assembly together.

 

you sersouly suggest using PVC pipe? Just asking because ive never seen it done before, nor have i thought about using that. But that might actually work.

 

I have had PVC pipe running from my RF fender to the stock airbox for about 4 years. It is the sewer pipe that I suggested. I was even able to flute the pipe entrance with a heat gun. PVC has a glass temperature of 87 deg C (189 deg F), above which the pipe will soften. I doubt you will see temperatures that high under your hood.

 

pvc works fine, i know 2 people that hve had pvc intakes and ne was a turbo supra due to lack of finding one with the right bends when he wanted to drive it after his swap!

 

i had this same post a while back. Obviosuly type r intakes have 3" piping but the best and cheapest way is to go on ebay and search for integra integra and just go through them and see which one tells you has a 3" piping. Some sellers mention in the discription either written or in their picture.
