How Much HP Can a B13/B14 LSD Tranny Hold?

This is under turbo due to the fact that the hp limits will be pushed by a boosted vehicle..just wanna know when a b15/p11 becomes a necessity...?

Also avoid solid discs, a friend of mine with estimated 250whp broke 2, both times 3rd gear, probably because he was using a 4puck unsprung disc with an ACT Xtreme pressure plate...

I beat the crap out of my B13 tranny pushing 283whp/264tq and never had an issue

Damn! I soooo want to do a mild turbo bolt-on setup just to get me over the 200 hp- 200 ft/lbs threshold.

Np bgreen. I suggest a t28 setup and some s series jwt cams and a calum ecu. It will be a basic simple set up for u. It has the potential to get closw to 300whp. That kind of power in a b13 is a feelings hurter to 75% of the boys on the street.

I agree with beto, i suggest a sprung disc. Im a big act supporter and customer, they mke great clutches.

Actually it's 175whp. Coming from the man himself, Mike Kojima.

Building the Bulletproof Transmission, Secrets of the Pros > MotoIQ > Magazine Articles

Is there no hope for the owners of the SE-R? Well, although the cure is elusive the situation can be helped quite a bit. The Nissan FWD five speed transmission is exceedingly weak. It can only hold around 170 whp in any sort of long term use and starts to become a very iffy proposition when the power levels exceed 200 whp. The gears are narrow, with third gear being amazingly, dumfoundedly narrow. The shafts are spindly and unsupported with wide spans between bearings which allow gear spreading flex. The transmission case is thin and weak; it cracks and flexes allowing the gears to spread apart reducing the tooth engagement precariously and making thing even more likely to fail.

Mine did fine at 230whp/220wtq, for about a year. I doubt it will live too much longer under boost.

Do a simple T25 setup, or go VE
