quick question will a sohc thermostat housing fit on a dohc? ka24

[AN89HATCH]

My friend has a broken thermostat housing, on his 93 dohc ka24, but all we can seem to find in the junk yard is sohc ka24's, is the thermostat housing interchangeable, since it pretty much is the same block? what about the timing chain cover, is this also interchangeable? thanks

the thermostat housing will fit, but it sit closer to the block than the dohc, you will need to bend/reroute some vaccuum stuff to make it look clean.

As for the timing covers go, i assume you could, the bolt pattern is the same, but the distributer/oil pump holes would need to be plugged up. Also the crank pully sits out about a 1/2" farther on the sohc than the dohc. So you will need the sohc alternator brakets to keep the belts lined up.
