ok, so i will get straight to the point. i want to build a k24/k20 hybrid engine. my three main concerns are the RPM ability of the engine, the r/s ratio, and hood clearence.

first. i would like to be able to spin 8200-8500 RPM's daily. can the wrist pins be relocated high enough to do this safely with stock stroke? every day, or almost every day.

second. to get the RPM's out of this engine that i would like, am i going to need a deck plate...or will wrist pin relocation be enough? i am a little skeptical about deck plates, but i also know very little about them. it just seems that bolting a spacer between the head and block is a bad idea.

third. if i have to go with a deck plate, hood clearence will be an issue. i have a carbon fiber stock hood, and i do not want to get rid of it or cut a big hole in it. i also don't want a hood with a big bulge in it. would it be economically worthwhile to have mounts made to rotate the engine so the valve cover points more at the firewall. i know this is done in rally cars to lower the center of gravity, but is it something that could be done for a street car.

or, does all of this sound like a waste? should i just get a de-stroker crank? opinions please.

 

well i read on honda-tuning that they are afraid to even go past 6500 and they lowered i-vtec to hit at 4500 so what u sacrife in rpms u will get more torque and better street driving imo. Up to u but i prefer a k20a2 built that can rev past 8600. If u want to rev and have a k24 then just do the tsx swap. This is what Honda-tuning had to say about the k20/k24 ABOVE 6500 RPM, PISTON SPEEDS GET SO HIGH THAT PISTON-WALL FRICTION STARTS KILLING POWER. IT WILL ALSO KILL DURABILITY IF YOU TRY BEING TO REV HAPPY. Right npw alot of the clubrsx guys r makin like 210-220 and 140-160 on i/h/e k-pro. Right now u should just do that and wait for more companies to come out with stuff then build it

 

anybody else?

 

This discussion on R/S might help you make up your mind. It has me rethinking my plans of destroking a K24.
