Cammed Motors Specs + DYNO Graph Mandatory

[EUR003act]

That is because the more aggressive cams tend to push the peak torque higher in the RPM range, thus benefitting engines which can rev higher. Also, when you say stage 1 cams for K24, do you mean K24A1 or K24A2?

not sure... alot of sites state cams for the K24A3 (us version) which is only 9.6:1 comp ratio...

heres what ive found so far:

K20A2: 02-04____________ K24A2: 04-05

int. pri.= 1.285" ____________ 1.313" - (Bigger)
int. vtc= 1.398" - (Bigger)____ 1.379"

ext. pri.= 1.291" ___________ 1.306" - (Bigger)
ext.vtc.= 1.369" ___________ 1.382" - (Bigger)

When you say K24A3 in the US, they mean the CRV engine. Make sure you ask for K24A2 cams. Not A3.

yeah i guessed that...

its interesting looking at how many different stock cams honda made for the k-series... tsx cams seem to have the biggest primary lobes... where as DC5R cams have the largest vtec lobes...

For interest sake, the K20A ITR valve springs are not a straight swap into the K24.
The spring seat & retainer would also need to be changed as the CL9 valve spring is more narrow.
That is the K24 retainer is too small for K20 spring & the K20 spring also has an unaceptable overhang over the K24 lower seat edge.
For those who don't know the lower seat basicly look like a thin washer.
It's made of steel & prevents the spring eating into the alloy head.

***DSP26's notes***

after spending $XXXX amount to get my car running, I understand now that those who were saying get a better Final Drive ratio are correct as it moves the entire powerband across to the left. Only reason i don't regret this build was coz my engine needed it... but in terms of first performance mod, final drive is better!!
