ATP does have the .84 housing in stock however, but that may be a bit small for a rotary given the 88mm compressor.

If I'm looking at these compressor maps right, it looks like the gt40 has a little bit more punch than the innovative gt66bb. Are you looking to replace the turbo long term or just in waiting until the gt40R is available? If you're just waiting, I'd try to find a cheap T04S or something to bolt on in the meantime.
So the GT40 compressor wheel is only 88mm on the exducer?...interesting.
How much are the GT40s selling for?

Yes, 88mm exducer diameter. Not too big really...but larger than the T78's compressor (GReddy) and it required quite a bit of machine work to get it to fit in the T78's compressor housing. Inducer is much bigger.
The plain bearing GT40 is also available with a .94 and larger housing so I'm not sure where the .84 housing on ATP's turbo comes from.
Turbo replacement is long term. I want to put it on, tune it, make miraculous hp and then forget about it for a couple of months at the least :-)
GT40's with the ball bearing center section are $1595.

Well heres my opinion.
Look at all the pro stock, pro import, pro whatever...all the guys running insane times/trap speeds are either running Innovative or Precision turbo setups. In my opinion you can't really go wrong. Plus if something does go wrong its handled here in the states probably. I think in the long run your probably better off with one of those. But thats just my opinion.

Pro Import Cars W/ Garrett turbos
Garrett is from the US. Why would you have to send your turbo to a different country to be repaired? They're also the single biggest turbo manufacturer in the world, you should be able to get repairs anywhere. They log probably a billion miles (literally) every year in the US alone.
Turbonetics turbos are on a lot of fast cars, too. You'll note 99% of top level competitors get their product for FREE, so they don't care if it lasts more than one weekend or not.

I looked at the precision stuff but what they recommended didnt seem right (GT37). Theyre all pretty much into drag racing which is fine, but on occasion I have been known to hit the road race course too. I would probably be happy with the Innovative turbo. Question is, would my wallet? Three hundered bucks is still a good chunk of change which I could put to use tuning the car on the dyno, having my injectors serviced, taking the wife shopping....

Is it just me, or does the compressor map for the GT76 Innovative look just about perfect? Am I reading that sucker wrong assuming a flow rate of about 60lbs. min. for my engine and running from 16 to 24psi? Seems to be right in its sweet spot. That thing has to be a bitch to spool though.....

BTW, I just thought of this. Depending on how Sean made the manifold, won't the GT76 compressor possible hit something? It's got to be a bigger diameter than the GT40R front cover.
