BKO upgrades?

[mlucasone]

Does anybody know if the BKO can be upgraded to compete with b2ks and impulses? I heard you can replace the 2-way valve with a 4-way. does anyone know if you can do this? And you can put in a chaos chip of course.

From what I have read you can upgrade it to be as fast as the B2k's (well semi-auto at least) but by the time you do that you can spend almost the same money on a B2k. But then again if you want to save money and upgrade in steps go for the BKO
