I was thinking about upgrading my stock s4 turbo which I have done in the past on my other TII which has a mild bridgeport. What the rebuild company did was upgrade the compressor housing and turbine and mated it to the stock exhaust side, I noticed the last time it from suffered boost creep becuase the stock wastegate was too small. Should I have the the wastegate ported out on the exhaust side, or will boost creep not be an issue on a stock motor? If I do do this should I add an F-con to the stock ecu as well, or some type of aid to the stock ecu?

Thanks

 

yes, you will experience boost creep on stock ports...port the wastegate.

 

i just had my turbo done at bnrturbos.com i sugest you take a look at some of his stuff. his stage 2 comes with a wastegate that is ported to 30mm which is way bigger than the stock 12mm

 

Great site! Looks like I will be using these guys. Thanks!
