I bought this when I was going to build a custom setup for my Corvette. The guy I bought it from said he drove to Florida with it on once and then took it off. It has obviously hardly been used. I never installed it. I have the receipt. The actuator is on it ("628actuator" if that means...

Reduced: $630

Still for sale. I'm going to put it on ebay today probably. ...Now on ebay. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=200545507745&viewitem=&sspagename=STRK%3AMESELX%3AIT

I bought this when I was going to build a custom setup for my Corvette. My friend Mark in Portsmouth (I don't know his screen name) said his buddy Al (also in Portsmouth) had a turbo that would be about right. He said he drove to Florida with it on once and then took it off. It has obviously...

I heard about the effective pressure at the injectors changing under boost. Apparently it makes tuning harder, but it looks like the only alternative is a boost sensitive fuel pressure regulator, and since the LS1 is a returnless system (only one fuel line from the tank to the rail, no line...

I'll have to study all these flow rates and efficiencies one day. Right now I'm content to trust you who know and just concentrate on buying and installingl. I know what you mean about high end power ITSNOTAGN. I consider sometimes that I should set my rev limiter to 6100 to save the engine...

I'm in Dahlgren, Virginia. I got 65 lbers and a Walbro. The injectors should be good for 670 hp but I'm not going that high, the pump should be good for 550 which is about what my goal is. I'm a member at LS1Tech but I wanted to ask the Buick owners about this since it's a Buick turbo. A...

Thanks, I'll take that advice. But will the boost controller I have plug right up to the external wastegate or will I have to get another one?

Thanks. I can't mount it in the front because the manifolds on the Vette come out so close to the cross member. I think it is possible to put a turbo on for relatively cheap. I'm on my way to doing it. (Of course if I were paid $5 dollars for every hour I've put into thinking about it and...

It's a stock automatic 99 Vette. I'm going to keep the engine stock since I plan on selling the car before long. I bought EFI Live, which is very popular tuning software for the LS1s. If you're curious, here's a great thread on FI LS1s with stock bottom ends. LS1TECH - Poll: My Stock Bottom...

I got a used GT6776 for a 99 Corvette and I'll be running methanol with the turbo remote mounted near the rear axle, but I was recently informed that this turbo might not like this low boost level. I'm not concerned much with choking power off over about 5k RPM's, I'm willing to trade that...

Gracias RUQWKNF. The consensus for the LT1 and the LS1 is that 7 or 8 psi is the max you can run (with methanol) on the stock internals before blowing something up. (The rods or rings on the LT1 are the weak link and the rings on the LS1 I think.) Will I be able to use the same boost...

Sh----. The little things tack on and on. You can save money building a turbo kit yourself, but if you made six dollars an hour at work, the number of hours you spend web surfing, thinking, buying, and working on it make it cease to be "saving" money. If you just bought the kit for 5 or 6...

A little screw in a box boost controller came with it. Is the wastegate rod the rod coming out of the actuator? If not, what is the rod coming out of the actuator that ends near the mating surface of the turbine housing called? Is the setup on the stock Buick turbo like this? What is the min...

I bought a PT6776E turbo used that came with the "628 actuator upgrade for Buick turbos" but I don't know what the minimum psi it will run is. I want to run about 5 psi initially but if the actuator's min is above that am I going to have to go to an external wastegate? I do not know much about...

Greetings. I have a PT-6776 that I got to put on my 99 Corvette. One thing I need is the 3 bolt mounting flange for the exhaust inlet but I'm having trouble finding one in the parts for sale forum. What should I be looking for? I'm not sure of the terminology, is this piece called the up...
