Hi, ported OEM or tubular GTSPEC headers for 360+hp with an 18g on a 04WRX ?
Just looking for opinions.

Many thanks

 

wouldn't bother with the tubular headers, from what i gatehr there very expensive for not a huge gain

 

How much do people pay for the porting ?
Ive found a set of tubular headers at a good price.

 

Ported headers from a good source will be about £150 .
Try Harvey (search the name) or David at Welcome to the API website

Ported will give better low/mid range torque.

Headers, go for Gruppe S type Version 2. Dead reliable and very light.
Need lagging remember but will tend to give high end benefits. Always use OEM gaskets!

IMHO with the 18g go ported.

I have had ported on stock V3 turbo, headers on 20g turbo.

 

Argh i hate making decisions. But i guess if the bug bites, which im sure it will id be better going the tubular route for the future.
