and keep in mind that it changed,  it went from a h23 head to a f22b dohc head which is much rarer, and the dyno is based on a prelude that i believe was gutted to weigh 2400lb's

huh???   weight doesn't factor into the dyno.   Definately acceleration, braking, and handling, but not the dyno #'s

Yeah I knew the dyno was based on a lude, but lots of build info is there.  One of the mods on 6thgenaccord.com has a G23 in his 6th gen.  He dynoed it at around 155whp.

still involves a crap load of dyno work and redoing the fuel map....            i would assume that they werent running a 6th ecu either?     and im sure they didnt increase the compression or bore out the sleeves

Kevin ...... did you know that you can't really tell anything about an engine's performance by it's peak HP?  HP is calculated, torque is real.  What matters is how much torque you are making per rpm before the peak.  The peak matters when you are on the track, but that's about it.  The torque delivered by this build from 2000-5000 rpm's is what makes it a very good idea.  This is what you use for a daily driver!

HP = (rpm*ft.lbs.)/5252

WOW! thank you! i didn't knew that actually... Falkore, ur the man! i knew torque was inportant as well as HP, but not that it was that important! so u think it's a good idea for me to get the H22 head? or is it the H23?

That's wheel horsepower.  The stock 6th gen f23a1 accord has 150 at the crank, not the wheels.  A stock auto accord probably only puts like 120hp(that's being generous) to the wheels. A little more for the manual transmission, but still nowhere near 150 to the wheels.

It depends on the amount of boost that you want to push ..... I posted on another thread what compression ratio results from both heads ..... are you trying to have the turbo and VTEC or do you plan to eliminate the VTEC ..... one has it and the other doesn't .... too lazy to look up the Wiki right now.

Before you do anything though, I'd try to find actual dyno maps to compare so that you can predict the actual benefit.

Of course the results will vary.  This is a "frankenstein" motor.  there's no telling what kind of gains any particular build will get you cause I nothing can be exactly the same when your swapping around parts from used engines.
