ok.. so the wastegate actuator on my ct20b is fubared.. i get boost creep like crazi...
i was going to get an external wastegate to replace it and weld the internal one shut. i just hv a question about size. i was planning on getting a tial 38mm w/ either .5(7.252psi) or .6(8.702psi) bar... i hv an mbc and plan to run probably 10psi neway tho... however, the shop my car is at, a customer has a 48mm wastegate but wants a 38mm and he said that customer is asking if i want the 48mm turbosmart wastegate in exchange for a tial 38mm... i'm assuming 38mm is a good size for a 5sfte... would i b better off w/ the tial 38mm or the turbosmart 48mm? the 48mm seems kinda big... i'd possibly get a lot of lag? not sure what other pros/cons there would be between the 2? any help? thnx This post has been edited by elvasoshexai: Nov 28, 2007 - 12:59 PM -------------------- |

99.999% of the time, the problem is something other then your wastegate. aftermarket downpipes or incorrectly set boost controllers are the cause of most of these problems. what gear did you set your boost in, and how much does it creep by?
QUOTE i think that was what was happening to me, as i accelerate it would be real sluggish but my boost guage would be reading 15 psi (what i had it set to by the MBC) I thought it was real strange you probably had a boost leak and didn't realize it or that flimsy relocation bracket that tweak made to clock your turbo wasn't sturdy enough. internal wastegates almost never fail.

I dont understand about setting the boost though, what do you mean what gear did i set it in? I think at the time, i had it all the way open, but the car was still sluggish. sheesh, i still have alot to learn.  --------------------  QUOTE (Galcobar @ Oct 15, 2008 - 2:44 AM)  You want power but have no money. That's a problem. Cheap. Reliable. Fast. Pick two. |
