240Z Turbo

Powerglide has been in the car for a few weeks and the mount has been fabricated. I received my custom driveshaft yesterday and it is now bolted into the car. The only thing remaining is to modify the exhaust and hook up my new Quarterstick II shifter.

I am not trying to be negative, but he did offer a refund. These days you cannot expect someone to be nice. I would take the money and be done with it or have it repaired locally. The balls in the CV axle cost almost nothing and it can be repaired for very cheap. Probably cheaper than the cost to have it shipped back.

BTW, If you look at J Taylor's post on his greddy manifold, that is the big Kahuna he has on it.

Rick, Are we still on for the big Kahuna turbo?

Very nice indeed. BTW, where did you get the turbo and intake

Anyone run a stage III turbine wheel with a .82 a/r housing? More specifically using a T04E 50-trim compressor wheel. I wonder how the spool difference is between the .63 and .82 a/r on the stage III stuff. Please let me know if you have any exerience...I am trying to get a turbo out.

Hanns, Thanks for the information. The title was sort of a joke. This is the new powerglide tranny I put behind my twinturbo L28. It is was built by BTE and has a transbrake and full manual valve body. I use an Art Carr 9.5" billet converter and Quarterstick II shifter. I have to fab the tranny mount, driveshaft and redo the exhaust. Should be running in 3-4 weeks.

Yes, the pics are "censored", but it was not my decision. The guy I am doing this for does not want some things to be revealed. Apparently, there is some competition to develop the twin turbo kit for the ZR1....Sorry This car belongs to a gentleman named Wayne. It is a Corvette ZR1 that we have set out to twin turbocharge. The car is being built at South Georgia Corvette Specialists in Thomasville, GA. I was called by the shop owner Aaron and asked if I would like to take over this project that was initially started by another fellow who got in over his head. I am fabricating the entire setup from scratch. The exhaust manifolds are 321SS and feed a pair of modied GT30R turbochargers. The manifolds also plumb a pair of Tial 38mm wastegates that dump back into the 3" 304SS downpipes. The downpipes are attached to inconel expansion bellows from SPD and are connected to the exhaust with a pair of http://www.turbohoses.com v-band clamps. Again, sorry for the blacked out portions, but the owner asked that I keep some parts confidential as to the approach. The turbos will feed a pair of 2.25" intercooler pipes through a custom air-air intercooler. This is a stage I motor meaning stock motor and is expected to make 650hp@wheels and 800+hp@wheels on the stage II setup. Stage II is lower compression pistons, headwork and cams. I will update the pictures as we make progress. You can see more pictures under my projects section at.... http://www.speedshopthagard.com/

TwinTurbocharged ZR1 Corvette

I figure I should put this baby to bed. My buddy called me to give me an update as he is having his motor built by this guy. His E88 got to 235cfm or so and he never did start my head. My buddy is so pissed with this fellow I suspect I will not get any results from him. At some point I should go and pick up my stuff(chopped up P90). Sorry, some things are just too good to be true!

Well, I have had my motor in the car for more than 4 years and have not blown it up yet However, give me some more time and I will see what I can do

I am making 8 of them, but waiting for the dimensions from BradD

Doug, http://www.spdexhaust.com sells the nice, but very expensive inconel/stainless bellows as used on F1 exhaust. The other bellows were purchased from turbonetics for about $50/per. The steel braided bellows can be purchased from most local muffler shops. BTW, when welding the dump tube to the cast iron manifold use a nickel rod. I believe we used a stick rod and knocked off the flux. You have to preheat the manifold and weld a little at a time, peening with a hammer between welds as they cool. This prevents them from cracking. The manifold must then be cooled slowly so the welds do not crack. Not difficult, but requires that someone have knowledge about what they are doing. BTW, you can just use some thick walled steel instead of stainless.

shhhhhhh

Atleast the 40mm, I also am a dealer for the Tial Wastegates

Huh Huh....You said tool

Doug, I am a GT distributer and sell the GT35R turbocharger. BTW, I give discounted prices to Z folks. For a street car you may want to run the smaller .63 a/r turbine housing, but for all out power applications you should run the larger .82 a/r housing. The .63 housing will flow quite well to support 500hp@wheels. The T04S compressor housing w/4" inlet is standard on the GT35R. We can have the inlet cut down to 3" and we can vary the flow of the compressor wheel from 50-65lbs/min or 500-650hp worth of air. Joel forgot to give me a shameless plug considering I just got him two GT25R turbochargers for his RB26 swap http://www.speedshopthagard.com

If it wasn't for those meddling kids I would've gotten away with it...Jenkeez
