Looking to do this in a b20z, do I need to take the pistons/rods out of the block and send them to a machine shop along w/ the bolts?

does this mean that the block will need to be honed again before reinstalling the pistons?

could someone tell me step by step what needs to be done so that its done right?

you should install new rings at the same time so honing the cylinders would be a excelent idea.

BUT if you are gonna go through the trouble of pulling the rods out just to install new bolts you might as well replace the pistons for more compression.......

also dont forget new rod bearings.......

 

I wonder....after getting the rods resized when using ARP rod bolts.....would you then have to use thicker bearings or not?
Since you are taking material off of the rod's bore wouldn't you need thicker bearings afterwards?

Yes, you do have to use larger bearings. If you don't have the right tools nor have ever done this your self; I recommend sending the crack as well to the machine shop of bearing resize.

 

When rods are resized material is machined off the parting faces of the cap and rod(usually around .003").When the rod is reassembled it is slightly oval.Its then bored or honed back round and to original size.The reason for resizing after using performance rod bolts is because they usually have more press fit and distort the bore.Depending on the final size of the rod,the bearings may need to be larger OR smaller.

 

A normal resizing job does not take very much off of the rod end. No, you don't need to use oversize bearings, ACL's that I have used with resized rods fit well within spec.

Excellent info

 

If the machine shop does it right,it shouldnt change much.Why not just get a set of eagle rods,im sure for as much money your gonna spend on rod bolts,installing,resizing,you might as well just get a set of whole new rods.

Bolts cost like $40 and resizing cost another $40 roughly = $80. Rods cost at least $350. Depends on what he wants to do with his application. Those were my costs, but shouldn't be too far off any where else.

 

ok,then if its stock pistons you are gonna use,then i guess you might not have much of a choise,i also suggest shot-peening them.
