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...Quote:

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.
damn your know your stuff adrian!

***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!!
