We here in Arizona have enjoyed having Craig attend and speak at Pontiac Heaven events each spring here in Phoenix and wish to invite the owners of these builds to attend as well. You would be very welcome here. We are proud fans of the H-O legacy in Pontiac history.

Default Don't forget the wastegate.

I also mentioned to Mike and Joe and it was an important part of Ken Crocie's Car Craft T-F tune: the original Turbonetics wastegate was only good when the exhaust was restricted with the original stock "pancake" cat and also the single behind the axle muffler. As soon as one opens up the exhaust system (dual Hi-Po cats or omitting same and good flowing mufflers), the Turbonetics wastegate cannot bypass enough exhaust to control the boost. If you note on Ken's CC setup, he used a much bigger wastegate relocated to the front 3in turbo inlet pipe. That worked.

I still have a Turbonetics wastegate on my Revival Firebird and on WOT, the boost will bang over to 10psi almost instantly even with the wastgate full open. Fortunately, I have an auxilliary fuel tank that I can fill with 102 octane (racing) gas and switch over to that if I want to make a full out run. Otherwise, I keep it about half throttle (a couple PSI boost).

If I had to put a "hope for" number out there it would be 400hp-450hp. I want to be able to drive my car several days a week and enjoy it as well as stay competitive with newer cars. Like Joe I bought My TA with a several years old rebuild that had never been ran. Well they said for about 30 seconds. I did get it running and performed a break in, but that was almost 2 years ago. I know, I know....I should have been done by now. My project sadly has taken the backseat while I researched and purchased the fire am suspension. The TurboForce system wasn't added to the project until a few months ago. Again like Joe I am going to have to tear the motor down to check it. The engine was rebuilt using a PAW kit and the previous owner couldn't recall the cam type. With PAW out of business I can't contact them to see what he purchased. Not to mention two of the large freeze plugs fell out of the block during the engine start. The engine is on a stand right now and visibly there are no cracks, but the machine shop will have the last word on that subject. I did find it odd that the same plug just beside the manifold exhaust flange on both sides are what fell out. Hopefully nothing is wrong, but I will be prepared for bad news. I was planning on installing a cam similar to the one used in the revival car. I was hoping to go with a 2043 Nunzi cam, but that was before adding the TurboForce to my plans and I understand that Nunzi is retired now. I had a 2042 in my last TA and I loved it. Being that I am new to forced induction I am going to start with the system as close as I can to the original. Once I have the system and engine worked out I am not opposed to exploring the use of intercoolers. My TA has a brand new 2-1/4 pypes dual system with cats on it when I bought it, so I will have to go with a waste gate. I am looking at airesearch T04B units like the one used on the revival bird, but I'm open to suggestions on other brands. I'm trying not to break the bank, but I do understand that turbos aren't cheap.

My engine is not #s matching, but the carb is correct. I'm going to email Cliff R to get the rebuild kit I need and then its off to Tom Benvengi for a rebuild with necessary mods. The engine is a 400 bored 30 with 6x-4 and a performer intake. The distributer had been rebuilt by Rocky during the rebuild. Regardless of what happens with the block there is my current situation.
