Can You Use An Aftermarket Waistgate With The Stock Twins
 

JUST WANTED TO KNOW THIS BEFORE I BOUGHT THIS HKS WAISTGATE

No. The wastegate for the stockers is "internal" to the turbos. If you are talking about an aftermarket "Blow off valve", the thing that makes that cool sound. Don't waste your money, they work fine and they are free. You can make the stock BOV's sound much louder by simply venting them to the engine bay.

I don't see why you couldn't. i'm guessing oyu would have to be non sequential, and would have room for the valve were the TCA was.

The waste gate is build in to the turbo not added on. All is not lost, you can port the hole to 1.24 inches or put the prespool door in the wastegate position. The prespool door is 1/10 inch bigger, and open the hole even bigger.Or you can make a new door even bigger, and port the hole to 1.38 with a good amount of door to hole coverage (seal) .

And why are you contemplating buying a new wastegate? What makes you think you need one?

exactly...do mods that are gonna help...this is just to look pretty and so u can say u have a hks wastgate

WELL I WAS THINKNIG ABOUT THE WAISTGATE BECAUSE I WANTED TO RUN A MID PIPE, I THOUGHT THAT I WOULD NEED ONE I HAVE A BOOST CONTROL

Just port you stock one...wait till you go single turbo to buy an aftermarket wastegate...one more thing "WHY ARE YOU SHOUTING AT US?"

oh sorrry about the caps thats my bust, thanks for the info, but im lost, so if i wanted to still put the midpipe on with my boostcontrol would it stop the boost creep, thats really what i wanted to know thanks again everybody

Boost controllers only control the wastegate. If the wastegate is already doing what it can, then there is nothing else a boost controller can do. Therefore, if you are experiencing "boost creep", the wastegate is already maxed out. Your only options are to:

1. Port the wastegate
2. Add restriction to the exhaust

In simple, no. If you are experiencing boost creep, a boost controller will not control it. However, a boost controller will control "boost spikes".
