I posted this because you can get B15 LSD trannys cheaper than P11 LSD ones. You can buy a Ring and pinion for a P11 new for $300 from Greg V.

Basically you can get a slightlyt beter box than a P11 if you mix an match B15 gears with a P11 FD.

So the guys with B15 gear boxes you can get your gearbox to run like a P11 with a longer 5th gear.

Damn.... I was wanting to know if that was possible, but didn't know what the numbers would be... thanks for the numbers Dre...

This is what I've been saying for awhile now. but no one wants to listen to me

P11 gears seem tall... hmmmm. 5th could be taller though.
