ah man what a tease...lol its like a commercial of an upcoming show ya really wanna see but are pissed its not on right now.. patience is a virtue I guess.. best of luck on the rollers.. I am very interested in following this thread as the ZR1 project parts list is considering either the GT35R's or even possibly the GT40R's for 385ci displacement.. again.. best of luck, will be standing by for the follow up!

Yes, but 3.73's were in the car when I bought it and I never changed them.
I'll have some more pics and video soon....

So far it made 575rwhp at 9psi boost. It hits 9psi by 3500rpm and stays flat as a board until 6,800.
Having a hard time with the ignition lead so no torque numbers yet, but the curve looks very nice, peaking early and barely dropping power at redline. (still 545rwhp @6800)

Here are the dyno results-
https://ls1tech.com/forums/forced-induction/591795-twin-turbo-dyno-results.html
The GT35R's spooled up great. I'll post up a dyno graph on monday.
I don't believe Precision makes a 5-bolt T3 exhaust housing bigger than .63.
If another manufacturer does make a 5-bolt T3 housing with a larger A/R I could test fit it.
Also, I've ordered pistons/rods and am going to built another aluminum shortblock to swap out as I hurt the stock one on the dyno.

if you go to atpturbo.com - they have GT35Rs w/.63, .82, and 1.06 A/Rs - I believe that you can get the internally wastegated 5 bolt with any of those (though you may want to call).
Any chance you can use the internal wastegate instead of an external?
Finally- in the pics it looks like the turbine and the starter are touching- any worries there in real life? Is there enough space to wrap the starter?
Any idea on a price for just the manifolds?
Thanks
Ben

A starter heat shield is included with the system, and with it installed there is still about an 1/8in air gap between it and the exhaust housing. I have the same amount of room between the starter and exhaust housing on my LT1 car with no heat wrap and it is fine.
Not sure on the price for just manifolds, but I'll figure something out.

GT35R-
http://www.atpturbo.com/Merchant2/me...egory_Code=GRT
GT30R-
http://www.atpturbo.com/Merchant2/me...egory_Code=GRT
They have the internally WG'd and the 5-bolt non-WG -
But who would want to go bigger, considering you have great response 791hp out of the .63 A/Rs!
Thanks again

Yeah, those should fit as long as the external dimensions of the housing isn't large enough to actually hit the starter.
Might be helpful with 400+ci setups if they did in fact fit.
