Last min. question about my piping.
 

Ok just like the title says, I am now on the last step of gathering everything that I need for my setup. I ordered my charge piping from race solutions, but until now I noticed that I ordered 2.5 in piping.(I was excited when ordering and did not think). I also got some good couplers for the 2.5, but now I'm thinking that I might have gotten the piping half an inch too big. Well the set up is a T25 off of a 300zx TT with a 48/63 in a EG hatch with a FMIC. I can tell that the piping is maybe too big for the turbo outlet and intercooler inlet and outlet. My question is, if it's ok to go ahead and run the piping and just squeeze those couplers till they hold? Also, the larger piping would just give some lag to the turbo right?

Any help is appriciated, Sorry if I missed anything.

Thanx

there are transition couplers that will step up/down in size.

It'll work... but it's just that it's not ideal. Generally, you don't want to step down the size right before the intercooler as it will hurt the flow... but .5" isn't too big of a deal.
