i did a quick searcher and came up with diddle......im pretty sure im gettin an 02 si this week and i was wondering if the k24 block was taller than the k20 block, thus causing a hood clearance issue....also any imput on the stock k20a2 head on the block....or how we feel about a jdm k20 type R head on the k24 block...thanx yo

 

you need to specify what k24a you ar talking about,, Yes the block is taller.

hmm guess im goin to have to do some more research...im goin to say out of a TSX...sorry new to the K-series game

 

Ok, basically... there is the

k24a1 - CR-V motor

k24a2 - TSX motor

k24a3 - Accord motor

k24a4 Element motor

The accord, element and cr-v have the k24a motor that DOES NOT HAVE VTEC... TRUE VTEC.. Read this for complete info on this

The only k24a that can carry the 3 lobe vtec cams is the tsx.

Now... if you want to use a type s head with a "Non vtec" k24a like the accord, element, cr-v.... and you want to stay with everyhting stock... you can only use the CR-V block, or the TSX block (although tsx head almost like the type s head)

The stock pistons and valves will touch if you try to match a stock type s head with a stock element or accord block. The pistons are a little bit different, that is why they touch.

I hope that is clear enough for you.

 

I forgot to mention on more thing..

When it comes to bare blocks.. they are pretty much the same, all of them... Only major difference is that the tsx block has oil squirters, the other k24a don;t...

Another minor differecnce is that all the k24a blocks have balance shafts in the oil pump... Only the CR-V block will accept the rsx type s oil pump with no modification.. the other 3, need minor work to accept the pump.
