machine work for forged rods with stock pistons?
 

in the middle of a build and heard a rumor that you need to machine down aftermarket rods to mate with the stock pistons. can anyone confirm or deny this?

Call Pauter they have experience with this, I heard something about a tapered rod end but I don't know the details

The best bet is to start by checking with the manufacture of the rods yeah.

yes. every rods in the aftermarket not fit to stock piston.
you should machine rod's small end or you can ask to manufacturer to make rods for stock pistons.

LT one is OE rod for zn6 , Rt one is aftermarket (skunk2)

Hi,

You already read my post. Didn't you?

I've asked to Skunk and they replied do it if you want to use stock pistons.

If you are building why don't you just get pistons too? This doesn't answer your question but it seems logical to me

Call Pauter or whatever manufacturer you're going with.

Gotta trust what some of us tell you sometimes..

yes you need to machine 90% of the rods on the aftermarket to fit the stock piston

for some reason the aftermarket designs have yet to catch up with the oem trend of a thinner top strap

Any idea who makes the 10%?

lets just say a certain UK company is planning to release a steel rod that will fit the stock piston very soon
and this rod has already completed a years racing in the Fensport car - winning the toyota championship

If you are looking to build a high comp engine, JE does offer pistons the will support aftermarket rods. The pistons are cheap. The factory ring landings look tiny and to thin push high amounts of hp. If you going to replace things don't take corners.

They offer 9.5:1 & 10.5:1 & 13.5:1 standard bore.

Why keep stock Pistons though ?

Some thread necromancy here...

I was also wondering about this. I was thinking of getting forged rods that fit stock pistons so I can keep the 12.5:1 comp ratio for some time and go FI in the future. Plus I also read that NA engines have had bending con rods since the stock rods are cheaply mass produced.

Would you know if said company will be making lightweight rods?
The ones on the market now are significantly heavier than stock.
