I have been curious as to the potential of the K24 motor, <U>by itself no vtec</U>. I have searched and found a few short geared trannies that would probably better compliment the motor. I was thinking along the lines of the TSX Tranny.


Anyway out of my searching I haven't found any cam info for these motors. Does anyone make aftermarket cams for these yet?

Also will pistons from some of the Vtec K-series fit into the K24 block to help raise compression?


I have found a few K24 motors for cheap(when compared to the price of a K20) and was thinking of starting a new roject later this year.

 

I havent seen a non Vtec k24

I think it has plenty of potential if you dont plan to abuse it with high rpm driving like on a road course!!

 

Nobody I know of makes cams yet.

Why would it be a bad idea on the track(road race)?

I wonder if some company would be willing to make a custom set?

I have some ideas bouncing around and I am curious to see what could possibly happen.

 

Rocket might be willing to do some regrinds of the stock cams. Send him an email and see what he has to say.

Piston speed gets pretty incredible at high rpm's. With that said I raced 5thgenjons k24/20 swap for half the autox season (with stock rods) and it ran great and is still running great.

As for cams, theyre going to be out soon Im sure. To build a custom set may be a little pre-mature.

 

Will the k20a2 intake cam work for the k24? If it works then you only have to get custom exhaust cams.

I doubt it. They use a completely different form of VTEC.

 

toda sells the de-stroker kit to make it a 2.3 liter which perfects the r/s ratio, then you dont have to worry you cant rev the **** out of it all day!!!!!

I call BS - post a link to any toda k24 destroking kit

some people have tried a S2000 ('04) crank to destroke the block to 2.2L - this has been covered before...there have been serious reliability issues with this setup IN THE PAST (not saying it can't be done)

I am pretty sure fastbrakes got around 160 whp 160 lb/ft tq with stock k24 hasport header & K-pro

 

k24's have vtec. Just not on the exhaust side.

The trick is to get the tsx tranny to mount up, no mounting kit for that as of yet.

It does not have true VTEC. No high cam and low cam, just a system that disables 2 of the four valves per cylinder below a certain rpm.

Yes, and the cam only has 2 lobes opposed to the other VTEC cams that have 3.

The K24's have alot of potential. I beleive Nikos on the board is using a K24.

 

The K24 does have a form of vtec,just not what your used to.It uses the same oiling setup as the K20a2.One of the intake valves uses a very low lift lobe,maybe .050" lift.The intake valve uses a larger cam lobe,maybe around .350".When vtec kicks in around 2200 rpm,the rocker pins locks the two rockers together which causes both intake valves two utilize the one larger cam lobe.
The head still has plenty of potential.None of the K20a2/a head parts will work besides the retainers.

Good info, I remember reading some **** on K20a.org about the difference in heads.

How about Pistons? Will any of the K20 Pistons work in the K24 w/o hitting valves?

 

All of the K20 engines use an 86mm piston while the k24's use 87mm.The F20c from the s2000 use's a 87mm piston though that may work.Not sure about the pin diameter or compression height.

 

Then why not just disable the "fake" VTEC on the intake side and build it like you would build an LSvtec. How does the k24 head flow compared to the k20?

 

If you disabled the VTEC than you would basically be running off of 1 intake valve.There is a way to lock the rockers together though.
I dont get what you mean by "build it like a lsvtec".You do not need to run any external oil lines for anything and it's two completely different engine's.
The K24 head flows decent,but nothing compared to a k20a2 head.The valve that is always "on" has a wierd port configuration.The casting on that side is built up and restrictive,compared to the "vtec" valve.
The K24 from the tsx flows about as well as the K20a2/a head and has the same vtec.

 

Oops, I meant to say allmotor LS, not LSvtec.

 

k24's are scarry......thats all you need to know....those things are beasts!

 

I loved my k24 Just not the car it was attached to.

 

they why didnt you just swap it in a eg chasis?

 

thats what I wanna do is put a K24 in an EG hatch

 

good ****! i love k series motors...if only they werent so expensive.
