Ok, I'm about to get an 89 CRX 95% rust freechassis for $250. The only thing making it just a chassis is because I guess it doesn't get compression because it needs a ring job.

Now lemme ask you...WTF does that mean. I'm most likely going to get it for a project car, but what needs to be fixed to get it running. I'm eventually going to replace the whole motor, but until then, I figure if I can get through fixing this engine it'l be a good learning experience for the future.

If there are any pages out there that discuss this and have pics etc lemme know.
Any and all info will be helpful.

I decided my 90 crx si is falling apart from rust so it's my new daily beater!

Thanks in advance!

What do you think I'd be looking at for costs if I did it myself?

 

Just get a used d series motor from someone here on HT. Use that until you do a swap. You will spen MORE money to replace your rings, than you would if you get a used motor for a little while.

 

I agree, buy a used engine.

But if you want to do it, a ring job means that the piston rings are worn out, and need to be replaced.

To do that, you have to disassemble the engine. Remove the crankshaft, rods, and pistons. The cylinder walls will need to be honed, to get the correct hatching pattern to break in the new rings. The block needs to be thoroughly washed out to get rid of any metal dust. New piston rings will need to be bought and installed onto the old pistons. When reassembling everything, you generally want to install new crankshaft and rod bearings, too. Then you put it all back together, and break in the engine like a new one.

So, you have the cost of:
New head gasket
New piston rings
New rod bearings
New main bearings
Cylinder Honing
maybe new rod bolts and/or head bolts

If the cylinders are gouged at all, then you would need to over-bore them, and also buy new oversized pistons.


I am in a similar, yet different position. I've got some B16 pistons I want to install in my B18A(my stock bottom end is in excelelnt shape with full compression, though). But for me, the cost and work of doing all that isn't worth it for me right now..

Hope that helped..

 

thanks for the help guys. It doesn't even seem like it would be worth the money for the learning experience! If I need to get it running I'll either get a cheap d series or just plop then cash into a b series...or just pull my a6 from my rusty rex and swap it

Thanks again. Made that totally clear for me.
