Over in the KA forum there is a discussion going on about high hp NA KA's. Someone brought up a fully counter balanced crank and being to rev to like 9 or 10k. I've been thinking for a while why no one has used on one a KA-T, I know it'd be expensive but some of you guys have a decent chunk of change.

Because there's more to it that jut revving to the moon. You must take into account the peak piston speed reached and the effects of reaching such speeds.

Because of the long stroke on the KA, the pistons would exceed the tolerable speed limits at 9k rpm.

Additionally, the rings would pretty much melt down in a matter of time. Maybe not a catastrophic failure, but a very fast ring wear issue for sure.

A destroke would be in order to reach those high rpm and it's just not worth the money it would take to fab up a kit, since there's no real significant gain from it on these engines.

Thats not even mentioning the head issues at that RPM....

The key to building a great motor combo is to attain the most useable power possible within a certain rpm range. I consider good power to be close to 400hp. But I want most of that available to me from just over idle all the way to redline. Thats how the world judges a good combo. For that, I give you the stroked out KA24DE. Apply a properly sized turbo, give me a half decent management setup and I'll net you enough ear grinning torque to make you urinate on the nearest vehicle equiped with VTEC...

Pretty much did that to the CRX that was "owning the road"

Easily done. Weld on the crank (and then turn them to change the locations of their circle) journals to add 1mm to the stroke and bore 1.5mm over. That gives you 2.6L, build it for wicked boost, and you are in a good way.

LMAO....I like the way you think man
