You might want to check out Jeff Priddy's dyno runs. He built a nice setup with an old school t04e/t3 turbo. He made over 400lb/ft of torque by 4krpm and 350hp. He's outlined his parts as well.

I have one. I'll dig it out today and see if I can run down to UPS for a price.

I have one with an external wastegate and I think I have a stock one as well. PM me if you're interested.

I have one. Pm me if and we can work something out.

I have a holset he351cw used for sale if you're still looking. Pm if you're interested.

You can launch the auto hard with a 2-1 drop on the last amber. I would also like to add that somewhere out there is a list of mods that will help the jatco hold together. The fluid you use will also make a huge difference. I used john deere brand hy gard fluid. The fluid will lower your stall speed but it won't matter if you do the gear drop at the line.

You'll have to best a 11.23 et in that chassis to be the fastest. I managed that in 2008. I wouldn't bother upgrading the stock turbo. I would go up to a 60 or bigger on the comp side. And if you're interested in any parts I still have the turbo and intercooler system kicking around.

Dump diesel fuel down each cyl. It'll loosen up after a day or two.

I have a some parts you might be interested in. Text me and we can chat.

I block off the blow off valve or install a pipe with out the flange and delete it for testing. Unfortunately Jeff doesn't use the v band flange on his setup. Are you on the same dyno? Have you run it at the track?

Call Jeffp about a .82 turbine housing. He might have one for you. Have you verified that your blowoff and wg are not opening? While I didn't do testing on the dyno with my old setup I went through a similar issue with a stage 3 .63 vs a .82 exhaust housing. The .82 took about 300 more rpm to achieve max boost but the power difference was very noticeable. I can't remember my trap speeds but it was obvious that the spool vs power wasn't significant enough to keep the smaller housing installed. The smaller housing also made the engine more sensitive to detonation. That was my experience.

I had consistant 1.6sec 60ft times with a r200 open diff on hoosier 26 x 8.5 with my 72.

Tim, call Keas in australia. They will have both the L and RB dimensions. Gzm is a shop I dealt with for my jatco. Good guys in my experience.

The z31 auto is rated to 350rwkw with keas mods installed. I would also like to add that by using john deere hydraulic oil vs trans oil you will be adding considerable holding power to the trans. My 3 spd jatco withstood multiple back to back runs at the track with over 400whp for years. The weak point becomes the converter & input shaft. I twisted several input shafts and ballooned 2 converters getting into mid 1.5 60 ft times.
