What internals do i need to change when i do a engine rebuild?

 

It would not be worth it to change everything, you would simply by a new motor.

Depends on the cause of failure.

 

you'll probably have to rehone, so oversize pistons and rings.

then you'll need all the bearings. probably valve retainers, too.

you can't take this to any old shop. The S2000 has FRM cylinders (most others are cast iron, FRM is a high-perf Honda thing) and the techniques are different in doing a hone.

billman is right, though. You may as well buy a used motor.

 

Theres nothing wrong with the motor except a crack where the oil pressure switch goes. All the internals are fine its just i want to change what is recomended since the motors out.

 

Personally, I'd either not mess with it or buy a whole shortblock for $2200 and sell off the broken block and internals. You put it up for $600 and someone will probably buy it.

 

Theres nothing wrong with the internals. The only thing is the oil pressure swtich got threaded and oil is leaking from it.

 

If there was no catstrophic failure, for example rings and a valve job, I'd build my own motor.

 

Since your engine is in good shape otherwise, I wouldn't touch your cylinders. But as long as you have the engine out, you should consider changing your crank bearings.

You should also consider replacing your clutch plate & T/O bearing since a significant portion of the cost is labor.

 

I think it all depends on your experience level and expectations. If you're done a motor before, have a good torque wrench and ring compressor, can follow directions to the letter and trust yourself to take apart and re-assemble precision engines like this one, then go for it. I've done it and I always worry after the fact that I forgot something.

Or you spend 2200 for peace of mind, knowing you've got a honda built block that should last 200K miles with proper care.

If this is the block I'm thinking of you're going to have to take it completely apart to have it repaired right? The oil pressure boss has broken off?

 

The complete motor has been taken apart.
