Hi, I will be rebuilding My Engine, in the next couple of months, and was wondering what would be the biggest ports I could go with a GT3540R with out changing the turbo

I really would like to go Half Bridge if i could, but maybe only a Large Street is possible

 

If you have no intention of running larger than a 35R than just stick with the LSP engine.

 

OK, thanks for the answer

Could I keep the GT35R and run a Half Bridge, or do you reckon If i want todo this it is best to ditch the GT35R and just get a bigger Turbo?

The turbo has only been on 6 months on a stock port and already want me power

 

Sell the turbo if your looking for a HBP. If you only want mid 400's to the wheels keep the turbo, run a nice ported SP motor with a good tune. Shoot me a email at sean@a-spec.com
