depends on what you consider your 240. i bought my 1st one for 500$ 91 fastback. bad ka24e & swapped it to a ka24de from a later year & now it runs like never b4 =]

now thats the waste of time there and its no gain.. just get your self a ob1 KA24de and drop it in an fire it up.. there are many around.. now if you plan on doing some other motor swap just keep the sohc and save some cash.

if you follow the list with a fsm near by, this car will start No issues bro

You said you want to put a ka24de in a 91? Te 91 240's already have a ka24de.

If the Valve Cover says "NISSAN TWIN CAM 16 VALVE"

It is a dohc

If it is a '91, it is a DOHC

I know.. mine is a '91

Looks like this:



But your valve cover shouldn't be powdercoated black...
