How much more does the K24 weigh?

A road race K24 making 300 whp is a tall order. I've been racing and building K24 for few years. My World Challenge K24 only making 275 WHP. Yes, it can make a few more HP if we do some exotic build, like smaller wrist pins, lighter materials custom pistons, and so forth. But that engine only last 7 race weekends before it starts loosing power. Realtime guys use fresh engine only for 2 race weekends, and use 2 more weekends on the used engines for practice.

Drag engine will make more power. Street engines also makes more power, and these guys think they are reliable. In most parts, they are correct, because no matter they claimed they taken it to redline all day long, it doesn't compare to a day of racing.

I realize it's a tall order. I'm expecting RPM will be the death of it, So I plan to use the Revs only when needed. It will make more power then the F22... it will make more TQ then the F22. Simple math shows both. It is about the same price to rebuild as the F22... Nope cheaper cause you don't have to sleeve it. The car runs pretty close to the WC cars now with A LOT less hp. If it can make within a few hp of the WC cars it's weight advantage should be enough to close the gap. It should have better weight distribution and better aero then the WC cars. I'd like to make more power but save that motor for one particular weekend....

I have the Honda tuning where it tells the exact steps needed to swap the K24 engine...that would be pretty useful to you I'm sure. That guy, I think kevos2K or something, did it already.

FYI he didn't use the stock manifold however, but I think he got a custom manifold from Magnus...been a while since I read it.

I Saw his article. It was kinda the... Ok this can be done point of the project. He did things a little different with the custom manifold. I believe he also did the K24 block with a K20 head if I'm not mistaken.

I found the link to the article...think he just used the full K24 engine...I think I remember him explaining somewhere on the forums why he didn't use the KA20. Could you use a custom intake manifold or does it have to be OEM?

Well the CRV enigine is a Single vtec Cam head (not single cam head, just vtec only on intake) much like the 02-05 160hp Civic Si's. Now I've tried to do a fair bit of research on this but from what I understand the CRV motor won't make much power, Like less then 200whp. The only way to make any kind of power on that block is to do a head swap to the RSX Type S head (or new Civic SI). Even then the Compression isn't very high on that motor. I do have to use the Stock Manifold. I paid $900 for the TSX engine from LKQ. From what I understand only the TSX got the 2.4L with the Vtec on both cams.
The Issue I have is the TSX head doesn't flow all that great so to hit the power numbers I'm going to have to have some decent head porting done. I'd love to run the RSX Type S head but it's not legal to missmatch heads and blocks in the class so I've gotta deal with the TSX stuff.
For TTC I'd do a CRV block with a RSX Type S head.
The build the way I see it to exceed S2000 hp on a K24 is cams. I've talked to several RSX guys that put (Accord,Element,CRV) 2.4 bottom ends under their K20 heads and a set of Cam's and valve springs and fired off numbers in the 240's.
