Does anyone know if Applied Technologies is still up and running? If they are does anyone know the #? I had some bad luck which kept me from working on my TTA for way to long. Now I am trying to pick up where I left off. The wastegate that I have is from Applied Technologies and it is not working right. I need a rebuild kit for it. If they are not in anymore then does anyone have any ideals on what would be the best wastegate to replace mine? Also I would like to know if any place ever started makeing roller rockers for the TTA's? I have a roller cam kit. But, at the time to my knowings no one ever put out roller rockers for it. I'm also looking for a place that has after market heads and intake for the TTA's. Being I don't really want to have my stock heads and intake done. Would like to keep them as is!

ATR is out of business, I believe the closed shop about 2 years ago would be my estimation. You might try contacting a couple of the Buick shops about getting a rebuild kit or the parts that you need for the wastegate. I'm going guess they used the same gate on the TTA pipe as they did with the GN pipe.
The intake is the same as the GN, so any aftermarket intake will work fine. You might be able to piece together your own roller rocker kit with the correct measurements but as far as I know no one sells a kit for the TTA. For the heads, you pretty much have your choice of stock, stock ported, and no AC. If you go the no AC route you can fit GN heads and you'll have a lot more options. If you want another set of stock heads there are a few members with a couple sets that were looking to sell them a while back, or you can find heads off of a 3.0L FWD GM vehicle in a junk yard near you.
Hope that helps a little, maybe someone can chime in on the roller rockers a little more.

Frank Weeks did roller rockers on his TTA, and maybe a roller cam, and his EM is [email protected].
