I want to upgrade my wastegate to a Tial and replace my Spark racing one. Can someone tell me the difference between the 2 other than its 3mm bigger . My setup is listed below if that helps. THANKS!

 

i have a 38mm for $200 + shipping.
it's not even been picked up yet!!!

BRAAAAANNNNDDDDDDDDDD new

 

Awesome! If you could tell me the difference between that one and a 35mm perhaps I would be interested. I did try search and nothing really explains the difference.

 

They use the same flange, the outside is the same side, its the inside diamteter thats 3mm larger. No major difference besides that that im aware of. Also the 35mm is discontinued, the 38mm replaced it.

 

AHHHH so all I can buy now is the 38 unless I buy a used one? Thats cool, thanks!

 

If I buy the Tial 38mm will it directly replace my Spark wastegate? I have on elined up but I need to know before I buy. Thanks

 

if your spark wastegate uses Deltagate 35mm Style flange, then YES the 38mm will bolt up.

Post the pics, I'll tell you if it fits or not.

Also, higher boost applications can get away with SMALLER wastegates because the air is under more pressure, so it escapes faster, so milder turbo setups benefit from a larger wastegate.

Not only that... but the wastegate needs to bleed off LESS exhaust to make MORE boost. People usually only have big wastegate problems when they try to put the majority of their exhaust through the gate to run some stupid low boost like 5psi

yeah, I just called Sparkracing.com and they said theirs uses the same flange as the deltagate. But I would call just to make sure. The guy I talked to seemed like he was rushing me off the phone and not really paying attention to me.

 

Hey I really appreciate your extra effort though. Thats more than most people would think of doing! Your in my book.
