I have a crvtec setup as of right now and had put about just over 10k miles on it. Runs totally fine, but now I am changin up the head with some skunk2 stage 2 cams and plan on revvin to 9000 with a chipped p28 w/ the skunk2 program. I just needed to know if the stock rods can handle that friction or not. BTW the engine is also sitting at 12.5-1 compression and has the Z10 block girdle.

 

I would be careful as the ls motor does not have the most favorible rod ratio for high reving.

 

I highly doubt that could stand that!

I'd at LEAST shotpeen the rods and get some ARP rod bolts. Even then I wouldn't feel safe. I've heard the stock sleeves don't like high RPMS and high compression very much either...

 

You will need at least ARP rod bolts and proper engine clearances to last at 9K. Plus I hope that Z10 girdle is installed correctly...otherwise it is just taking up space in that oil pan and that is about it.

I had a b20 with stock rods and now i have to buy new rods and had to fix
a 5 to 6in hole.

 

rods are fine. need arp rod bolts though.

 

Agree, my friend's CRVTEC goes to 8400 with his ITR ECU, stock sleeved running 84.25mm JE 12.0:1 slugs, and it's been running fine now for about a year now... 12.62@107 in a full inteior EK

 

taking it to 9000 with stock rods and unbalanced crank could lead to probs quickly, but i know people making incredible power with drop in 12.5:1 pistons on stock rods and a built head revving 8500

 

i would never take it that high without balancing the pistons rods and crank

 

honda balances their **** pretty well.

 

this is true, however from my experience, it can always be done better.

 

i'd agree...you should balance the crank and have it polished...there is a guy on here that is in the MD area...think his name is nonvtc allmtr...something like that...revs his b20 with stock everything but pistons to 8500rpm...and aparently he hasnt had any problems...but i dont know how long it has been running like that

 

Balancing is key but, the "weak" point in LS or CRV -VTECs are the rods bolts. Stock versions give way to tensional stresses under high rpm loads. This is why ARP (at the very least) rod bolts are recommended.
