well i need to know if the ka24de head (duel overhead cam from a 94 240) will directly bolt to my 1990 block. i want to switch heads...i want the duel overhead instead of the single. now i know my 90 comes with the 2.4 ka24e and i just need to know if they are compatible and what major adjustments if any i might need to do during this head swap. do i need to adjust the ecu? will the newer head bolt directly on the air intake manifold and exuast manifold? please help!

No

Im going back to the other forum. This place is filled with newbies.

incorrect.

you can put a dual cam head on a single cam block, but it's not a bolt on affair.

first off, you compression ratio will become 11.1:1.

then, you'll have to figure out how to get the chains to work.

and you'll need to use the DOHC intake and exaust manifolds.

It's a fun project not worth it IMO.it gives oyu either 11.1 or 11.7 compression doesn't it?Depend on what SOHC piston you got...I know there is 2 write-ups about it.Search I'm too tired,,,,falling out of my chair.Good luck if you do it.

Its sohc pistons in a de. If not, let me see some links and I will stand corrected.

You've lost me...It's SOHC block correct?And putting a dohc head on it? Or you put SOHC pistons into a DOHC block?With the DOHC head

[InsanityInc]

Putting a DOHC head on an SOHC is the same compression result as putting SOHC pistons in a DOHC engine.

Ive seen Sohc pistons in a Dohc long-block. I have never seen a Sohc block with a Dohc head.

Ive seen Sohc pistons in a Dohc long-block. I have never seen a Sohc block with a Dohc head.

then search...people have tried it, some stuff doesnt really line up and such.

emil...just swap in the whole ka24de

[TheSnail]

Are you telling me to search? If ish does not line up right, then why would I search for something that I think would not work in the first place.

[emils_240]

now should i swap the transmission too or can i just to the eng?
