I am picking up a 92 coupe later this week and it has 223,000 miles on it. The car is 300$. The body is shot for the most part. What i want to know is weather or not it is worth rebuilding the ka24de and swapping it into my 89(ka24e). The motor is seized up right now. I am looking at new main bearings, connecting bearings, piston rings, full gasket kit for 300$. That is if the motor is still repairable. Is there a big difference in performance between the ka24e and ka24de. I plan on just doing a N/A build. I figured that if the motor is shot i could make most of my money back by parting out the car. What do you guys think? Should i chance it and buy the car or wait till spring and pic up a ka24e from a friend for 100$ and rebuild it. Tag on another 150$ probably for a timing chain kit.

We are looking at 800$ for a fresh rebuilt Ka24de.

Or 550$ for a fresh rebuilt Ka24e.

what do you mean the body is shot? as in frame damage? or just rusty/dirty?

You can't even get rolling chassis most of the time for that cheap, so go for it.

The difference between de & e? about 20hp stock and a few lil things here and there. DE has more aftermarket support relatively.

It's worth as much or as little as you think it is worth.

From your post, I'm more confused than anything else - it seems you already have a 240, and getting another one? I'm not sure what you plan on doing w/ either of them (parts car, race only car, daily driver, etc, etc).

Yes i have a 89 fastback right now.(has the ka24e motor) Later this week i am buying another 240. It is a 92 coupe with HUD. The 89(daily driver) seems that it is starting to die. It is starting to smoke out the exhaust more and more every day. Usually when i sit at a light and them take off it will smoke for a second and the stop. This doesnt happen every day. I just figured be prepaired for what might happen soon. Every engine dies ......yes even nissans. So i was going to pic up the car and start a rebuild and them swap it late this summer. The car's body(the one i am buying) is not in that bad of shape but i didnt plan on keeping it. My 89 fb is in better shape and has less miles on the body. Dont really have any room for the second 240. I saw the car at night and the shop owner just said the motor was siezed up. The car is at a auto shop sitting in the corner of the lot. Apparently the owner doesnt want to repair it so the shop owner bought it for 100 bucks or something. Now the shop owner just want to get rid of it too. So i shot him a number and he said come by later this week when he gets the title. I looking to build a daily driver/ street car. Just mostly bolt-ons. Hoping to reach the high 14 on all motor. Flywheel, custom intake, Full exhaust, remove secondary butterflies, under drive pullies, clutch, remove a/c, remove mechanical fan and replace with electric fan, and maybe a mild cam. Just a mild and relayable street car. I could keep the coupe and gut it and every thing and turn it into a track car but i need to graduate high school and then i will be going to college. I dont know if my uncle will let me keep the car at his house for 2 years or more while i am at college. I will post some pics of the car when i get it later this week.

its not 20hp diff... and u can make more power from the sohc than the dohc na... trust me.... why does nissan motorsports use the sohc? the only reason why the dohc has like 10 more hp is cause it has a higher comp than the sohc and one more cam...

If you're going to college you should probably get some reliable transportation and forget about messing with cars for a while.

Old guy speech done.

The DE motor has a lot better aftermarket support and will see 11:1 compression with your E pistons swaped into it. So you have a huge freebe right there. Plus for $300 you can part it out. Just don't piss off your uncle or get the city after you for having a junker in the yard.

On the other hand, you might be looking at a motor that is FUBAR. But for $300 you can't get burned too bad.

looks like i will be sticking with the sohc after all. The guy switched and now wants 400$. I can go with out that and build my own N/A sohc. This guy put 12:1 JE pistons, Custom intake Manifold, 70mm tb, header, and a jim wolf ecu and he is throwing down 275 to the wheel.

I doubt that is to the wheels. He didn't dyno it either, so it's all guessing. I saw his post in the for sale, and looks like he's saying to the crank, not to the wheels.

275hp to the crank possibly, if it really ran a 13.9 quarter mile... maybe - can depend on a lot of other factors such as weight of the car (could have stripped the car down), tires/rims he ran - so from all that info, you can get a ballpark amount.

Still impressive, but I doubt 275 w/o at least a dyno.
