RE: GSR actual WHP
wrong...it makes about 170-175 at the crank...between 140 and 150 at the wheels.

RE: GSR actual WHP
oh my badd. Is that the JDM version? A guy i know said that this "
all im saying is the fastest honda to date has a b series...theyve had k motors for like 5 6 years now, still cant peak wat a B can push out." Is this true? or is he just a moron?[/align]

You have to ask yourself what your goals are. While the K is not fully developed yet, for a street motor it already surpasses 99% of the B-series stuff running around out there.
I see a lot of guys with borderline "streetable" B-series engines running 2.0-2.1 liters with sleeved blocks, 13:1 compression, big cams, etc. They usually end up putting down somewhere between 240 and 260 whp on my dyno. Very respectable numbers. In comparison, take a standard K20A2 out of an RSX. Bolt on a Comptech Race header, CAI and exhaust of your choice. Add a set of JDM ITR cams, some good valve springs, an over bored TB and a Hondata reflash. You're now looking at 235-245 whp consistently without touching the bottom end or head. You've got a more reliable motor (near OEM reliability), a broader torque curve (I-VTEC) and frankly, with a catalytic, you can still pass emissions, even a visual in Cali. And we've already seen what a little more compression (12:1) and bigger cams can do - 265 whp on 91 octane.
I guess the point is, the K-series today (in its early stages of tune) is already the equal of a fully developed B-series street motor. And you can get that equality with virtually no mechanical skill/knowledge. Just bolt on and go. As development proceeds (heads, cams, etc.) that power will come up substantially and eclipse the B-series.
So, where do you want to be? Near the end of a great engine's development cycle (b-series) or at the beginning of a new era with an engine that already equals its illustrious predecessor?

RE: GSR actual WHP
and to answer your previous question, the american b18c1 is supposed to be 170hp i think, and the jdm gsr engine is 178 (the advertised number) i'm pretty sure.

RE: GSR actual WHP
The K series motors are the best for power, but they are still kinda new, so there isnt too many around for the price of a B. Give it a few years and youll see more ppl using K series, as soon as they become cheaper. As for the GSR.......Sacicions has an EG with a JDM GSR. The JDM GSR has about 180 to the crank, and HE has a video dynoing @ 160 whp with a crappo ebay intake.
