I think you should have gone for a GT30/40 as they can have external gate setup and often spool up just as well as a smaller turbo but with no real limit on the top end potential unless you plan going past 25psi on a 2L turbo.

I am sure it will happen now that the bigger turbo bug has bitten. When I changed from GT25 to GT30/40 I gained bottom end because the 4 inch smooth intake and smooth exhaust housing with no internal gate were that much more efficient

The 28RS the car is running has a rear housing with no internal gate (running a 38mm tial). The exhaust path is very smooth.

There is simply no need for a larger turbocharger, as it is (with a rich tune) 3rd/4th gear wheel spin is an issue.

Yep, I can personally vouch for this car, it is a true animal.

I drove it on the weekend and it is a scary little machine- if you so much as look at it the wrong way it WILL bite your nuts off!
