Rteck 20
 

Hey guys I was wondering if I need to port my Stock turbo waistegate to prevent blowing my motor. I have 720 all around , rteck 2.0 , full racing beat exhaust.

From what I know, it's always a good idea to port the stock turbo wastegate on the S4's. In order to reduce or prevent boost creep it's always recommended.

What about s5

The S5 has a good wastegate design out of the box. You can learn more here...

btw, unless your question/issue is absolutely specific to the RTek, you'll find you'll get more responses in the general forum (2nd Generation Specific (1986-1992)). Only a small percentage of the forum members visit the RTek forum.
