I think some may get confused on the B15 trans. The B15 trans when I use it in context, is referring to the B15 SR20 transmission. Just so there isn't any confusion with with the B15 and the QG18. The QG18 stacks are a direct swap in if you have a P11 trans. If you are unlucky (ha) to have a B15 trans and need new gears, you can swap in the QG stacks but you will need to get the older 4.176 FD out of any older SR trans, as long as it is LSD.
