I have been looking at missions lately that can handle 800 plus HP. So I am limited in my choice of missions. However, I have recently come across a few deals on HKS dog missions for the Z32. I have searched for the posts and googled but could not get any results in the past two days. Anyone know what needs to be done to attach the Z32 mission to the RB26? I am aware the internals are the same, but I am thinking I might need a custom bell houising adapter or something like that.

I would think that would work also. The shifter will be farther back into the car but nothing a little custom fabbing cant fix. time for a sequential shifter A. What r u using for axles. I could see that being more of a headache than an rb25 trans. Os giken parts are nice. If your balling out of control. Source a r34 bell housing and get a supra getreg Transmission. The r34 awd trans was an awd getreg. I think 700 crank will be the max my s chassis will ever see unless its full tube. rb25 trans are like 800 and I will risk blowing one to pieces but with shockproof oil one should hold 700hp. Os internals would be pimp but are not offed by OS.

Just an FYI. This RB25 s13 in MD went 116 in the 1/8 when his transmission broke. He thinks he was maing 750+ hp at the time.

I am looking to make between 800-900HP. The OS gear kits are nice but for 1,500.00 more than the 5 speed kit I found an HKS Dog Mission (Z32). For 6100.00 I can pick up a Pfitzner Performance full sequential, Dog Engagement Kit with straight cut gears and Billet forks that fits into the RB25DET Casing.

I had looked into the supra option before but never found anything that confirmed that it would work. Finding an R34 Bell Housing is not the problem. Believe it or not it will be finding the Supra Mission.

Mike - You going to the shop today??? You should see my new hooptie, I am pimping SR18 power power now.

Well besided headstuds and thicker headgasket. Yes stock bottem end.

If the transmission would have held the car would have made a 9 second pass.He has a powerglide in it (or going in it) Should run consistant 9's next season.

You can use a z31t or z32n/a transmission by swapping the bellhousing off of an rb26dett transmission. Not sure if the rb25 bellhousing will work.

I did this in my car, so I know for a fact that it works. Beware, your shifter is going to sit 4" or so further back. I had to cut the floor, and weld up my shifter. Quite honestly, the location is much better for me because I am tall.

No it is true. Stock bottom end. He has a turbo 350 in it now. I haven't talk to him in a while so I don't know what stall converter he is running or any other details, but the car is on the street with the transmission in it.

I am going to keep looking and I will see what I come up with for my budget. This is the reason I do not have mny engine sitting in an S15 yet. I figure I may as well take my time and make sure I got the parts I want and need vice settling for what is available at the time. Thanks for the input you guys have definitely opened my eyes to a couple of other options out there.

OS internals are available for RB25DET and RB26 and Z32 Missions. It is all the same gear set, you just have to order it and have it all put together.

No. But it's really funny how there setups are close to each others. I could have sworn it was nates car when I saw the pic he had up but this guy live in MD. Nate is in FL.

would the z32 TT trans bolt up if the bell housing was changed to a rb26?

yes, it would bolt up to the block. the shifter may not be in the ideal spot though...
