Im going to hone block to fit OS type s pistons.

Question, Do they come with wrist pins?

should I get lighter forged rods? Is it worth it?

Should I get new bearings mains, and rods?

Or can I just used mine and just get arp rod bolts? They have 95 k on them.

 

You will be fine with that.. I dont know about wrist pins..

 

most of type s piston sets that ive seen come with rings and pins.

 

will i be alright using the stock bearings?

 

The pistons should come with new rings and wrist pins.

No, forged rods aren't really needed in your application.

Yes, if you are in there replacing the pistons, you should go ahead and replace the main and connecting rod bearings.

ARP rod bolts are not needed on your application.

 

its going to be a built na motor, hopefully shooting for some good numbers, with honda bottom end, so do need new oem rod bolts, or can I reuse the old ones?

 

IMO stay genuine honda in the bottom end. You can reuse all your fasteners I even reuse the head bolts.
Beware of honing that block, our blocks have teflon like coating on the cylinder wall. Service manual says 600 grit or higher, and suggests not to hone. Some minor wear in a vertical fashion is normal and nothing to be alarmed about.

Helm has some very useful info

its called a nikasil coating on the liners

It's not nikasil, it's FRM.

 

soo you can't hone H22 blocks?
How do you squeeze in the OS pistons?

 

Honing the block is scratching the inner surface to allow the piston and rings to flow smoother without creating suction and eventually causing serious problems, and boring is widening the diameter of the cylinder. if you need to bore it out more than go ahead but honing does not allow for more room

 

well thanks for all the help, I think I am just going to be getting a h22a and pulling my motor, and building it slowly, probably will sleeve it eventialy, but it just takes time! I have a helms, and its the best thing you can buy when it comes to working on the car.

Not necessarily. Honing is more for allowing the rings to seat properly in the cylinders.

Boring is when you need to make a bigger change in diameter of the cylinder, and it also will make sure your cylinder walls are perfectly round and straight.

Honing will take some material off, but not too much. It will take off enough to fit in the OS pistons, but that's about it.
