Need some info on the KA24de

[cheezy240]

Well I'm picking up a 93 hatchback this weekend, it has a 95 KA in it but it has a spun rod bearing. It has not been ran longer then 30 seconds to make sure it doesnt mess anything else up. But I was wondering what all should I get done. Like what will the crankshaft need done? and what is the ratio on the engine stock? And the rods and what not will stay stock for now. It come with an extra block and a head that I am going to get cleaned up and build that up when I get this engine running, I want to go turbo KA later in the future. I tried the search but it didnt really give me anything. So flame if you like I'm just trying to get some info. And I'm only 16 and still in high school that's why I was looking for maybe a price range because I'm not made of money Wendys isnt a great place to work haha. But if anyone could help me I'd appreciate it

Bump, really no one? Come on Nico peeps don't let me down

and what is the ratio on the engine stock?

Should be 9.5:1 for the s14 KA...

Not sure if the crank needs anything at all done to it...

[cheezy240]

oh ok and what is the best ratio 9:1? and ok I thought depending on the shape of it I would have to take it to the shop or something

The first thing you'll need to do is find a good machine shop. Have them check the crankshaft to make sure the spun bearing did not score the surface(s). Then, I would have them tank (clean) the block and assemble it to stock specs with a quality rebuild kit (bearings, gaskets, etc). I say this, because you are not made of money and any future boosting will probably not be huge if you want to keep it reliable and not bust the bank. Keep it simple, and do it right; ask questions from professionals in the engine biz where you will get your work done. But get the crank checked first!

Alright thank you very much! and ok I'll do that but the engine with the bad bearing I can't pull it I was just going to go in threw the bottem and do it. I need it running for school/work and I was going to build up the other one and drop that in.

Ah, well honestly I've always pulled the engine. Either way, you'll need to have the crank checked and use new bearings and seals. You'll have to pull the head off if you're pulling the pistons out, in which case you should get a new gasket kit and replace the piston rings too. Putting them through the bottom would not be a good idea. Good choice keeping the other one as a build though.

Yea I knew I would have to do that. And could I do the main bearings that way to since I'm going to be in there? And idk if I'm going to mess with the bearings yet I guess I will have to wait and see.

Yea I was going to fully rebuild that one and get aftermarket cams, rods, pistons etc. And turbo that one.

And do you have an idea of how much it would be to get the crank done?

Yes, do the mains ... replace ALL the bearings. You'll have to make some calls because machine shops and their pricing will vary especially by location. They will tell you if you can use the crank or not, so the price should initially only be for checking it.
