Why would you want to swap out the P11 for a B14? They have the same finals but the P11 (Unless 99) has a shorter 1st and 2nd gears. If you plan on going VE in the future you will want the better / stronger gears of the P11 trans. If anything i would put the B15 final in the P11 and be done. I would keep the P11 no matter what, no point in down grading.

You cant use the sr16 fd unless you have the mainshaft from an sr16 as well. The pinion has to match the fd/ring gear.

3) Can I install the SR16VE final ratio with B14 internals

The thing is that I have an SR20DET currently N/A with a P11 tranny (cause it was boosted). Right now I dont want to change that engine since I know that its in good shape and is an extremely reliable engine for DD, but I dont want it to be stupidly slow, so I thought that with the shorter SR20DE gearbox with the SR16 final ratio it will help it rev faster, and will also be a good upgrade when the next gear I put an SR20VE in my car...

And Im being offered a B14 LSD gearbox for real cheap, but it has a broken housing, so I was thinking of buying it (for real cheap), then getting myself a cheap housing, and get an SR16VE final ratio from Gspec, and then I will sell my P11 tranny, the thing is that this is my only car and I cant afford to have it sitting in my garage, so its a good thing to be able to build the other gearbox in the garage while I get all the parts

Thanks guys

1)Yes
2)Yes
3)Yes

You're confusing Beto.

You can use swap over the Final Drive from the SR16 to B14 lsd transmission. This is what Gspec sells.

The Final Drive includes the ring gear and pinion/output shaft.
