I bought a 94 hardbody with the single cam 2.4 in it it has a knock to it so I pulled the motor and it has a bad rod bearing. Is this motor a ka24e?

Yes, SOHC KA is the KA24e.

Typically bulletproof, but a good opportunity to do a DOHC swap!

I believe the timing chain ate the guides and trashed the pickup and starved for oil

Ah. Yep, lack of maintenance.

Keep us posted on what you decide to do!

WHAT ALL has to be done to do the dohc swap? Are those motors easier to find

If you go with the frontier KA24de its a direct swap.

Find a wrecked Frontier, or search "KA24DE frontier engine for sale."

Okay I'm trying to figure out some questions here I have a 97 Nissan hardbody pickup with the ka24e motor trying to figure out if a 93 ka24e will work I know the Distributors aren't the same so how would I make this motor work for this truck

You need a truck motor. A DE motor from 1993 is going to likely be from a 240SX, which I believe has a different bell pattern and won't bolt up to a truck trans.

You need a 98-04 truck motor.

That's the thing I already got the motor in bolt it up to the transmission everything lineup good but when I went to hook up the wires for the distributor the 97 has a built-in coil and 93 does it and I'm wondering if I just probably have to splicing into the harness and put a coil in that's the only thing I can think of or that or like you said get a new motor got any ideas

Since you have the 97s wiring harness, I'd check if the distributor from a 97 would fit in the 93 motors distributor opening. If not, see if the front timing cover from a 97 will bolt onto the 93 motors block.
The distributor bolts into the front cover and its gears mesh with those of the crank sprocket and oil pump.
Check the part # and pics for the front cover from both a 93 and a 97 that way you can ensure they're compatible before buying/installing.
