Its under the Mazda Rx7 Stage 1, 2150 with exchange of your twins and they will gie you back twins capable of 420hp?

i think that means that's the top hp they can acheive if you max them out on boost, you'll still need fuel upgrades etc

Never heard of them. Undoubtedly, their numbers are bhp, not rwhp, which equals 360 rwhp, which can be accomplished on stock twins.

BNR's 3rd stage will give you those numbers. Or a nice single.

yeah, I was thinking rwhp, lol, back to reality.
