B18C1 Potential Question

[CQuester]

Just wondering what's the peak HP potential for a fully built B18C1 (block and head) on 91 octane? I've seen/read people able to build it to 225whp (~250 crank hp?), but wondering if it can be squeezed for even more, given the limitations (91 octane, California SMOG rules, etc).

Above question was for N/A engine obviously.

BUILDING THE HEAD DOESN'T REALLY GIVE YOU THAT MUCH, IT WILL JUST HANDLE MORE POWER, YOU COULD GO WITH 12-5-1 COMPRESSION BORED .40 OVER, BUT THE MOTOR ISN'T GONNA LAST AS LONG AS IT WOULD WITH 11-1 YOU'D PROBABLY HAVE MORE THAN 250 HORSE

[CQuester]

The figure of 225whp was from a PP head with valvetrain, and 11.5:1 (?) compression pistons, sleeved block to 84.5mm.

Cams, injectors, fuel rail, Adj FPR, throttle body, intake manifold, pistons, rods, valves, valve springs, cam gears, and so on all help to create big power. Take off power steering, A/C, and everything else that just creates belt friction. You can build serious power. There are millions of combinations to power, but finding all the right parts that match up just right, create huge power. 250 seems really low for the maximum potential of the B18C N/A.

Yes by full built, I meant everything you listed - port/polish, big cams, cam gears, valvetrain, pistons, rods, injetors, fuel pump, Hondata, etc. Remember, we're limited by 91 octane with no octane boosters. What'd you say is the max the B18C1 can output - 270 crank hp, 280?

d00d it is IMPOSSIBLE to answer this question, why not list the mods you WANT to add and we can give you an accurate idea of where it will lie

amen to temp... give us what you want or what you will do, and then ask...
