i see all these guys using ls rods on all there ls vtecs but for the same price i could get a set of eagle h beam rods and arp rod bolts. my question is, can i use eagle rods with usdm itr pistons in an ls block? are there any modifications that need to be done? I'm just curious because i don't think i've seen a single ls/vtec use eagle rods with oem itr pistons. all opinion appreciated, thanks

you sure can,any b series piston will fit those rods

 

Eagle rods are designed to use a floating pin piston. You will need to some modifications to make the fit.

aftermarket rods=aftermarket pistons. oem rods=oem pistons

 

of course you dont see aftermartket rods with oem pistons... cuz the oem rods will handle more stress than the oem pistons... pistons are more than likely to go out before rods... just go to a machine shop that deals with hondas... im pretty sure they have some ls rods laying around that they would like to get rid of...imo you're just wasting your money getting aftermarket rods...especially if you have a street application that is allmotor...

 

what i'm really worried about is weather or not the ls rods will handle 8500 rpm?? i would use arp rod bolts and i would have them shot peened.

 

yes it will handle it ... you need a gsr girdle to rev that high

riiight

Im sure ur talking from years of experiance

 

and u dont need a girdle. damn i hate these threads

 

why dont you need a girdle?

 

I ran an LS/Vtec with reworked OEM rods, ARP rod bolts and 11.5:1 compression using PR3 pistons for 40,000 miles, reving it to 9,200 quite regularly and never had a problem with it. I did not have a gridle. It was carefully built with lots of attention to detail. The motor is now in its 3rd chassis, and as far as I know it still runs like a top.

 

Ls rods are liter than eagle and I've take my ls v-tec to 10 grand with ls rods with no probs. good luck

 

but you can put aftermarket pistons on stock LS rods. IB has probe racing forged pistons that meant to be like stock, but theyre forged.

 

If you are using OEM rods (ie: press fit), then the piston makes no difference.

why wouldnt it make a difference? even if theyre forged pistons?

 

Wether your pistons are designed for floating pins, or press fit pins, the pin still floats on the piston. The only difference is the receiver groove for the wrist pin clips on pistons designed for floating pins. If your rods are press fit (OEM) then the receiver groove is not used, as the pin is retained by the press fit into the rod.

Because there are plenty motors that run without it, reving 9000RPM or more.

B16's don't have a girdle but they have slightly better stroke ratio then GSR and LS motors, GSR girdle is a good thing to have IMHO.

but is that still a good combo? stock rods with forged pistons? Sine the probe pistons are made to be used with stock rods, well the ones IB sells anyway
