I am running a GT42 on a 20b and a lot of people are telling me to run two small wastegates like two tial 46 mm instead of one big wastegate like a HKS 60mm,they said a big wastegate is hard to control the boost .Any suggestions on what to do.

 

1 big wastegate

 

You might do a search because I posted something about wastegate sizing a little while ago. Has some interesting thoughts by Reted with running multiple small wastegates. I ended up going witha large single but havent ran it to find anything out.

 

i tried a search and could not find it ,any ideas where to find it.

 

One 46mm should be enough.
Who has had trouble with the 46?
Or are you talking about that eBay crap?

i am not talking about ebay stuff and i think i might as well go ahead and get the Tial 46.

 

Well if the 46mm Tial is not good enough for you I believe they will re releasing a 60mm version soon http://www.tialsport.com/prod_wg.htm unless it has been released already.
