alright, i was wanting to go with 2.25" piping, but the guy who is making the piping is out of it right now and only has 2.5" piping, i was wondering is if this would cause a significant amount of lag on my setup, which is a T3 60/48 on a d16y8.

 

Does he have 2" pipe?

 

2.5" piping is fine. That's what I'll be using with my Y8.

 

also, do they make reducers to run that size pipe to my turbo?

 

Yes, you can get a rubber hose to connect it. For example, mine wil go from 2.5" to 2" to hook up to the turbo.

 

No, it will make practically zero difference in the amount of lag. PM me if you want me to explain why I say this.

 

alright thanks for the help guys, i think ill just go ahead and get the 2.5" piping, i need my car done by the 24th and am only home this weekend to do it, so i need the piping. and its only 1/4". prob lag by a few hundred rpm's if it does at all.

 

It won't even lag by a few 100 rpms. The 2.5" piping is better, IMO.

 

2.5 will work fine and you will have no lag. What turbo are you running
