Anyone know how I can beef up the tranny to handle high HP applications. I'm going to be re-building my engine for a turbo, and some really high psi. I want to know if theres a swap, maybe with a Z32 tranny, or even just some modifications to the tranny I have right now, that would make it strong enought o withstand the power.

Also, does anybody know if there is anyone who makes gears for our cars. I wanted to lengthen 4th and 5th gears, for some more top end speed. Don't ask me why I want to go faster......I just do Any help is appreciated. Thanks.

 

how much power do you intend to have?

 

I'm looking for along the lines of roughly 400 or more horses to the wheels.

 

you won't have to upgrade your transmission then. it is capable of up to about 500hp.

 

Well thats a relief!! lol What about lengthening the last two gears though?

 

Try here:

Seems like they carry various products(used/new). Email them and see if they can get you a set of dog gears depending on your HP application.

 

Couldn't you just get it heat treated? I've seen guys run everything from full HKS drag trannies to hardened gears and M/t coolers. If you beat on it enough it will break regardless. I don't see how the stock KA tranny can take 500hp though. Somebody care to explain?

 

it is the same tranny as the jdm counterpart except the bellhousing

 

Even the JDM stock tranny isn't that tough. Somewhere I have pics of a friends tranny when we drained it teeth fell out as well as part of a metal drain rail. He only ran it last summer.

 

hmm...i dunno then...but i have friends in oki and tokyo who are running stock trannies with that much power and no problems. the S15 tranny is ****...the S14 is supposed to be the best out of them all

 

What is the rear end gonna hold.....
From old school Nissan/Datsun....
R160 ---200hp
R180 ---275hp
R200 ---350-400?

And can anyone confirm for a fact that the rear is an R200?

Hank

 

Yes the rear end is an R200.

 

The rear end is good for 400hp.

 

Sykikchimp is that to the wheels or flywheel?

 

anyone?
