KA24E to KA24DE....Head swap?

[dragnsoul28]

I was wondering if it was possible to just switch out the SOHC head from the E and put the DOHC head from the DE in its place. Are they interchangeable? Wouldn't it just bolt up? Both are 16 valve...both are 2.4L. Need help quick!

trying to figure out the samething man. i hear that you can and then i also hear that you cant. but if i find out 4 sure ill let you know and if you find out before i do, let me know. lol. on the post that say u can, they say it will bump your compression up to between 11.1:1 and 11.7:1. idk man.

the KA24DE head will not fit on the block. just wont match up properly.

it has been done...with modification to the de head...not worth the cost imho...there is a thread on the forums about the guys build with details on the mod somewhere..you will have to search for it..it was a legthy thread if i remember correctly.

it is possible, with not many modifications. guy on here that goes by smug510. check him out. he done it. has pics posted and all. so dont listen 2 all these people that say it cant be done. they say do reasearch before u ask, but they r the ones that needs 2 research before they answer, lol.

the only thing is the SOHC is a 12 valve and the DOHC is a 16 valve. only mods i understand u have 2 do is to the timing chain cover. its a little different between the 2. and the compression parts of the heads do line up, head bolts, coolant passages, ect........
