Hi,

I am currently installing my GT23V. The flange was made to keep the position of the original turbo inlet. I want to keep my original air filter with the u-shaped connection (to keep the original look).
This means I keep the original manifold. Now I have to run the inlet tube within the u-connection. It works but I can only do it with a 2" stainless steel welding thing that should run down between frame and alternator (SD) after passing the u-connection.
The plan is to install an IC behind the bumper.
The question is: Is 2" IC tubing too small? What is a good compromise for reducing the turbo lag and flow resistance?
The turbo outlet is angled so a direct connection to the manifold is also difficult to do.
Please comment.
