TTA DP puck size?

[ALXTTA 1]

Hi,

Asked in the TTA forum but I guess no one is sure. Does anyone know the size of the wastgate puck on a stock TTA dp? And will it seal ok on a turbo with a 1" wastegate hole?

TIA.

Hey...I was just browsing the board & saw your question, so I called a friend of mine who according to him says the stock TTA puck size is 1 1/8", the same as a stock turbo Buick. He tells me that the TTA puck is usually very centered & although close, it will cover the 1" wastegate hole just fine.... it worked for him when he put a bigger turbo on his own TTA w/ stock downpipe.

Sweet...just wanted to doublecheck if I'd need to get a bigger puck or not. Thanks again!
