Quick question. I'm currently running an aftermarket turbo (T3/T4) setup & I'm utilizing the factory (ported) wastegate. My boost controller is setup properly, however I'm getting boost creep/spikes.. and having to control such from happening with the throttle. I've brought the car over to Hayes & Atkins a few times.. and they're unsure of what the problem is. On Wednesday I'm bringing it back to Hayes for a few hours so they can do an in-depth analysis of what's going on. I'm thinking I should just switch to an aftermarket exhaust manifold so that I can simply bolt on an external wastegate. However, many of the people I've spoken to have said they've seen people running similar setups who are using the factory wastegate & are having no problem with creeping. All the hoses have been checked & are fine, and the arm doesn't seem to be stuck either. Anyone have any suggestions? Thanks in advance.

isnt that a small turbo for a rotary?

1) The hoses for the boost controller could be too long or too small.
2) The boost controller itself could be too small.

My first thought would be that crappy *** internal wg that can barely support the stock turbo.

is the t3/t4 a smaller turbo then stock? if not and its significantly larger, then i would say its the crappy *** wg.

You're getting your terms mixed up.
It is next to impossible to do this.
