It could be a backup for the two vr sensors on the flywheel though, yes?

yes. 60-2 rear main setup takes the place of the two bell housing sensors.

Got busy at work today, i'll call you later Mark.
I have the opportunity to buy a used 15K mile gt3071 for $500 or a gt3076 for $600. I'm thinking of purchasing the gt3076, seems like a good deal and a pretty good turbo for what I'm doing. Any thoughts are appreciated. The 76R has a Garrett .82 A/R with a 4 bolt flange and a 4" anti-surge compressor housing

It just depends what you are hoping for in terms of spool. The 3076 will make at least 15 psi by 3500 which will make decent power, but full boost will be closer to 4k under most conditions. You can make the same power and spool a lot faster with more modern options. Of course, the cost is higher. That's the trade-off.

If it were me, I'd be looking hard at an EFR 6758 or 7163. Both turbos will put you around 400 whp on race fuel, one with more headroom than the other, so you just have to pick whether you want more spool or more power. Personally, I'd run the 7163 or 7064 on a quick spool valve with race gas. I think that'd be a ridiculously fun track setup. Not cheap though of course.

Also, watch out for e85. If you're just running at the track and bring your own drums, why not run a real racing fuel? E85 is cheaper, yes, but I have my doubts about it's ability not to get water logged over long periods of storage. Its a great fuel other than that and the fact that it isn't consistent at the pump. I guess you wouldn't be storing it if you were running in a 24 hour race though. You'll probably use it all!

Chris I think that you are right that the EFR 7163 is the best turbo, they question just comes down to money. I think that I'd be into that turbo for $2200, investing that type of money would make me want to spent a lot more on the supporting mods. This year I'm looking to step up but that might be a couple of steps up. The lag isn't that big of a deal, I keep it at the redline usually. I'm just looking for bang for the buck. I'm thinking about staying with the stock intake, but uprading the exhaust manifold.

[loxxrider]

That's not a bad path to take at all.

This ever get any further?

[gregplatt]

I've just been collecting parts. I didn't race it this year, but I did the previous year. I never could get together all the parts I wanted so i might change my plans a little with it. I'm waiting on a new place to do the work.

Spill the beans, what are the plans for next season? Are you close?

Cool project, love to see more pics/vids of the earlier results as well as future projects.
