ok, so i'm thinking about how i can get power out of my engine the best and cheapest way. the obvious choice is the 3.0L, but all that BASICALLY does is increase the stroke. bore x stroke of stock 2.5L is 3.33 x 2.92 and in the 3.0L it's 3.39 x 3.39. now our bore and stroke are highly condusive for high revs, which depend alot on rods and stroke (along with cams, valvetrain, etc). the Civic Si, as well all know, is a very high revving car. well the stroke on that engine is 3.05. so all else being equal (which it is of course not), we could theoretically rev higher, yes? even our tranny seems geared for high revs. so what i'm wondering is, what kind of valve springs do we have, what are the capabilities of those springs, etc. i know our rods are sintered forged, but that's all i know. do we have any choices for aftermarket rods?
just in case you're wondering, if we got cams that just bumped the power band up 1000rpms and got 170 torque at 7800rpm, that would come out to 252fwhp. just think about that. the way our tranny is, a shift at 8000 rpms would drop us down to 5000 or higher in each gear, which is just about perfect. you know what my roommate's NSX puts down? approximately 175tq at 8000 and approximately 266hp. sound similar?
also, with all that really high-end flow, the two stage intake would be a hinderance, so we'd prolly need a single stage intake manifold, or possibly just eliminate all the butterflies along with the actuator and all the linkages.
so basically, i need to know what our valve springs can take, what our rods can take, and if rod bearings will still be an issue. and if anything needs changing, what would i look for to replace with?
thanks,
