Because In addition to accomplishing something Im trying to learn, not just blindly follow what someone else I've never met says. That way I can become less ignorant of buick turbo engines as well as learn abit about turbocharging. All 3 of my other engine endeavors have custom crankshaft modifications I am spec'ing. Not sure what the crank has to do with implementation of a low-mid rpm turbo setup. Both the chev and poncho factory engines Im doing are routinely turbocharged when they were not from the factory. The Harley not so much but it might be possible. Did you read the title of this thread I started before attempting to insult me?? Just trying to find the actual weak points that would limit the stock block. Maybe there are some issues I could address now. I don't have a stage 1 or 2, the stocker is going in.
Here on this forum, Turbocharging is not an add-on. It is part of well engineered combination. A total vehicle package that has been created to work together. This means even the rest of the car is completely integrated into the thought process. You would be surprised to find that the actual turbo itself is sometimes the dumbest part of what makes our cars work. This package works much better for you when you start with one that worked well to begin with. Buick's combo worked well. You need this head start. This is why I said for you to start with a complete 86 or 87 Turbo Regal set-up. I'd like to mention everything from engine management, AF ratios, timing, cams, transmissions/torque converters, heads, headers exhausts, scan tools.......the list goes on forever! You don't really have a chance starting this way.
The horsepower numbers you have mentioned using the other engines you described above are easily achievable when working with 86-87 TR set-up. But not so much so starting from scratch with the wrong year.
Do you believe Buick used the same engine exactly the same way from 1978 all the way to 1987? In 1978 the Buick 3.8 was a turd. By 1987, the Turbo Regal was one of the quickest performance cars in the world. Don't you think maybe the little changes were important?
There are too many things to integrate into the set-up that you just won't have. Not to mention that the block and the build is not the same, no matter how close you think they may be. The differences you may think are minor are MAJOR in the turbocharging Buick world. Your have a friend who turbocharges? Forget him. This isn't about turbocharging. It's much more.
Buick Stage blocks shouldn't even be mentioned. These were Buick Motorsports offerings. They normally requires special attention and custom parts and are usually assembled by those who have years of experience using their propriety knowledge. There is also nothing special about any performance part described as being "GNX". To describe it simple for a new guy, and for your intents and proposes, the GNX is nothing more than a design package offering from Buick. Basically a real bad-ass looking standard Turbo Regal with a a different computer chip. No special motor.
Your questions could all be answered as time goes on. Start over. Wax-on...Wax-off.
Buy the right set-up. Make friends in your area. Go slow.
