2.8 power

Ok, I'll crumble and use F/I. I think I'm gonna start looking at Buick T-Types and pattern a system after that. Maybe start with a small Garrett off a Detroit or just find Buick turbos and use them. Ill start with one in place of the stock airbox, then maybe move to two after I get the first one worked out. I still need to iron out engine management because this will def. need more fuel than I'm flowing right now. Any ideas are greatly appreciated.

quattro tip tranny can handle about 300ft lbs of tq. if your planning on going above that you have to lvl 10 the valve body then you can run whatever you want

Doing 1 then moving to two is a waste of time. pick one setup to go after from the beginning. I would do a single. Garrett GT30. Haven't run any numbers to see what wheels or a/r's to use but thats the size for this motor.
This doesn't need to be a "marvel of engineering" project. You just have to have reasonable expectations going in. If you want 400, 500hp you are going to need to do a lot of engine work, build a more robust system and spend a TON of cash.
If you want 250-300whp that is reasonable on a stock block with good boost response and a very linear torque curve on a motor this size.
It's not rocket science.

Yet the same $5grand for the roots s/c @ 6psi for 270bhp, after s/c driveline losses ~200whp is waaaay cheaper and similar results? What am I missing?
and where do you think you are going to get this piping and manifold for your 2.8 project? the vr6 already has the manifold made for it, and you have WAY more room to place the turbo so all you have to do is fabricate a downpipe. thats a LOT easier than making your own manifold, and custom piping to stick on the stock 2.8.
Even at 6k and 300bhp - conservative estimates on both sides - its not ridiculously overpriced for the results. I'm not sure where you are come up with this stuff.

Well I'll go for the lvl. 10 valvebody I think I may go with a GT2052. It's rated at 225 hp, which I figure is enough for now, later I may move up to the GT30. I'll get the manifold custom made as I was going for custom headers anyways. I personally believe that with good engineering and ingenuity this motor has actual potential. Some of you 1.8 guys are as bad as the 2.8 diehards, which I don't understand. Do you actually not want to give the engine credit or do you just not want give the owners their day in the sun?
