Does anyone have any info/experience with this turbo? I was just wondering as it seems like it may be a good choice for my upcoming switch from twins. I am about to have my engine rebuilt and at least partially bridgeported. Just wondering if anyone knows some more about it. Thanks in advance. Laterz.

that is a HUGE turbo.... good for drag racing .... what are your plans for the car

I'm looking at a half bp FD, V-mount IC setup, Power FC, fuel system, all suspension work, pretty much all the goodies. I want to car to still be streetable when I have the boost turned down though. I am shooting for 475rwhp@15-16psi though. And I'd like to be able to set it higher when I'm running race gas as well. Pretty much just for drag racing. Auto-X isn't going to be a consideration. Even if it was, the half bp should spool that monster pretty quick. What's your take on it Vosko?? Also, you say it's big. But it's not bigger than a T78 right?? Thanx in advance bro. Laterz.

Well damn, if you only plan on running that 15-16psi, why get a turbo that has a peak efficency so higher??? Doesn't make sense to me, unless you want braggin rights......

I was going to look into a GT35/40 setup. However, I started hearing that they tend to break up power wise on the high end. Also, I was warned that a half bp motor might prove to be too much for a 35/40. I am looking for an alternative to that turbo. So it's the T04R, the T72BB, or maybe the T-51R Kai BB. And I never said that I was going to stop at 15psi. I just said that's what I want to run on pump gas. I will have a map for race gas and around 19 or 20 psi. I'm still wondering how much smaller this turbo is than a T78. Any help here guys?

T-04R or T-66 for the boost your running and plan on running.

What about the whp numbers I'm shooting for? Also, is the T66 a bb turbo? I know A-spec tuning is saying that they now have a T04R BB available, but that's the only place I've ever heard of that. The WHP numbers are very important to me since I'm shooting for a very low 1/4 time. Plus I'd be lieing if I said I didn't want some bragging rights with having the highest WHP 7 in the SC RX-7 club. The biggest reason is, I was looking at the Pettit Banzai package and I just feel that they want too much money for the product that they are supplying. Granted, that car is scary fast and gorgeous but hardly worth the $39,000 they're charging to do it.

The "Garrett" T72 is bigger than the "Mitsubishi" T78. The T66 is closer to the size of the T78.

Igy, thank you for the clarification. I am fully open to suggestion here guys. What turbo would be good for what I want and the kind of porting that I'm going to have on my engine? Like I said, I don't want a T78 and therefore not a T72 either. But I don't think that the GT35/40 would be able to satisfy what I am needing. Any and all help will be greatly appreciated. Also, I would prefer a ball bearing turbo. Thanx in advance.

T66 will work good, like jspec mentioned above
