Registered
in all seriousness a STOCK gen 2 all motor, without pulling valve cover?
know I am gonna get flamed here ~220
and not the motor will break, just that's how much power you can make

all motor then add Nitrous, ~40-50 shot valve springs are on the softish side for much more spray
so now you are at 260-270

BOLT on turbo running Fuel ~240-250

Bolt on turbo runnine ethanol based fuel
follow this thread

internally the "weak points" in a Busa motor
when you go in the motor, do rods, cylinder and main studs and a output shaft and LET IT RIP

Talking 220 at the crank? If not I’ve never seen or heard of anything close to that. On pump gas?

1340cc dyno'd 221 RWHP at 11,800rpm at 2WDW on MR12. Motor has been leaned on a bit, not very reliable for streeting, eats buckets and cams.
