Why not consider twins? two small turbos will spool up alot quicker eliminating lag. I've played alot with turbo stuff and for what you're after, I think you'd be a lot happier w/ two smaller wheels vs one large one.

If its in the budget, EFI is absolutely the way to go. I do this stuff for a living and would absolutely recomend it. While there are some really good blow through carbs out there, for the best in street manners and some semblence of fuel mileage, you just cant beat the EFI.

I've played with alot of different systems. Personally I like the XFI. Its user freindly, they have good support and it does most everthing you'll need. but I use BS3 on all my drag radial stuff. It has alot more to offer in overall control in staged limiting. It can be a little quirky and has some idiocincricies that drive me crazy but it works second to none when you're trying to put 2000HP down via a drag radial on stock suspension.

If the right recipe is followed, your HP goal should be exceeded easily.

Good luck on this, I'll be keeping an eye on this thread for sure.
