***SOLD!*** I have a stock (unported) intake for sale. Comes with intake, dog house and fuel rail (no regulator). Has all the dog house bolts but one rail bolt is missing. Dog house is drilled on the drivers side for IAT sensor, so that would need to be plugged or welded if not needed. Asking...

I am selling an RJC powerplate for stock intake setup. It has the EGR hole welded shut. If you still run an EGR, just drill it out. It will come with two new AC gaskets. $40 shipped obo. Also selling a champion "Turbo 6" EGR blockoff. Only a few months old, paid $27 shipped, asking $20...

My car has a Holley HP that was installed and tuned by the previous owner. I was wondering if anybody had a pump gas timing map that I can compare to mine to make sure it is "right". I can get the idle and all the wot stuff dialed in easily enough but I want to compare the "in between". Thanks. Joe

I have a holley crank sensor brand new in package. It came with my Holley dis setup for my HP but I'm using the stock one. Brand new in unopened package, will include a length of the pigtail that came with the ignition harness. Costs $80 plus shipping new, asking $65 shipped obo. Thanks. Joe

GN Billet vacuum block. Used for about 300 miles before switching to the TTA style. $35 shipped obo.

I have a set of ported heads that came on my TTA when I bought it. I don't know who did the port work. The heads need work- at least one needs valve seats redone and the other needs guides. My shop did the guides in one and when they went to cut the valve seat, they realized that when they...

What is everyone using for a knock sensor with a Holley system? I had read somewhere to go with a stock one as it is already "tuned" to engine harmonics and set it up from there, so I had purchased a new GM 10456287 knock sensor but cannot find any setup info for it anywhere. Does anyone have...

I have a front cover for sale, some scratching in the oil pump cavity and corrosion at the cooling jacket. Not perfect but definitely usable. $50 obo. Located in Port Charlotte FL.

What are the chances anybody has one they want to sell? I'm about to bite the bullet and order the billet one but figured I'd ask first. Thanks

I recently picked up a turbo ta and it has this turbo on it. Somebody said that it looks like an old "34" precision turbo from the mid 90s sometime?? It's tight and seals are good, so I had a hard time believing it was that old, but anything is possible. The exhaust outlet is 2.258 diameter...

I'm sure this has been beaten to death, but for some reason, the search isn't working. I have a tta with ported heads, 50# injectors, rjc power plate, forged pistons (9:1 cr), holley hp efi and bigger turbo- unknown journal bearing with a 1 piece compressor cover- will probably post a thread...

Just recently bought this car and, unfortunately, the previous "hands" in it had no right being there. Been nothing but un-screwing what they screwed up the past couple of weeks. Anyway, it's been smoking intermittently. Sometimes barely any at all, other times, it just billows out the...

I just picked up an 89 turbo ta with a Holley HP system in it. I'm in the process of cleaning up the wiring on it and wanted to verify the ignition wiring. They have the "est out" on the holley going to a white wire on the ignition connector and the "bypass out" going to a brown and white wire...

What is everybody using? I just replaced mine with I believe a walker part and it was extremely soft compared to what I remember them being. Didn't last 3 days before crushing and falling apart. Are there any out there that are better than others?

Hello, I just picked up an 89 Turbo TA with a Holley HP EFI in it. It "looks" to have a pretty good timing map (pic attached) based on my experience with other turbo motors, but I was wondering if anyone has anything to share based on turbo Buick experience? The motor is about 9.5-1 (GN...

Anybody have anything? I need 2-3 nuts and washers and a driver's valve cover, doesn't matter about the breather location, I want it for the passenger side to run a second breather on it. Thanks in advance. Joe

I just picked up a TTA after 13 long years since selling my last one. The car is rough around the edges to say the least, but I do all my own paint, body, interior, engine, you name it work, so it will come together in time :). Anyway, the car is missing the center tail section, I know they...

Along with all my other questions, I have a question about the injectors on my car. They are a style I have never seen before, the previous owner told me they are a new style 35lb injector. They are much slimmer than any other injector I have ever seen and appear to be a light gray/white color...

I was wondering if TTA's had IC fans like the GN's. I thought they did, but mine is missing. If so, does anyone have a setup for sale? Thanks. Joe

Anyone ever experience this? The tach in my car is off by about 1/2 when it revs. I will be full throttle, motor winding out and the tach shows 2800-3000 when it shifts.. If I rev it in neutral, it is the same way. Also, it seems to be a bit "jumpy" while I am driving. It will bounce...
