So i had a s4 turbo 2 setup and it blew! dew to what i think was a mixture of my fbcd and a stock wastegate. so i converted my block to the s5 longblock and still have my s4 ecu and everything that goes with that.

so after rebuild and porting i am producing 10 psi and i want to do 15... i want to know if this is ok or not as well if someone can give me the answer to that.

also im wondering why my s4 build would produce like 20 psi and this one if only doing 10. im guessing because my s5 is working write

but to my main questing i just dont know how a wastegate works or how it mounts so if anyone can help me by directing me to something i should get or that has a good pic so i can get a idea of what to get...



thanks. if any other info is needed just ask

 

You have an s5 engine with a stock turbo. The stock s5 turbo wastegate flows better than an s4 wastegate, so you will have less boost creep. You can't really replace the wastegate on a stock turbo except if you go with an aftermarket actuator.

This really belongs in the 2nd generation technical section.

 

ok ty for the info


i would have went to that form but i wasnt able to see it for some reason...all there was, was 1st gen and 3rd gen threads.
