if the main weakness in most ls/vtec's is rod bolt failure or rod stretch... how can thi sbe prevented without upgrading the rods?

arp rod bolts alone do the trick?

ARP Rod Bolts.

Shotpened LS Rods.

Actually depends how high you wanna rev, I've seen people use just the bolts, but I will be doing the rods as well, better safe than sorry.

 

just want to go to 8

 

use the arp's and get the rods re-sized

 

Arp bolts will be fine. Before I rebuilt my ls vtec, I was using stock rods with arp bolts and I was using an ecu done by locash and he didnt put a rev-limiter on it. Whenever I would miss a gear it would shoot up to 9k+ and My rods were fine. One time I hit 9950 according to my V-AFC and the rods never let go, so ARP will be fine up to 8k.

Also a friend of mine is running stock+ ARP's in his ls/vtec, takes it to 9200 daily!

Just out of curiosity what happened that you have to rebuild it now?

 

nothing just considering upgrading

 

Like the other guy above I'd recommend arp bolts with shotpeened rods. I had that with b16 pistons in my last lsv set up and it was nice with my old 402's

 

imo the rod will break long before the bolt... we were making 185hp and turning 8500 daily in our stock bottom b20vtec for about 25k miles with no problems from the rods or the rod bolts

 

i rev 10k all day long @ the track.
shotpeened rods with arp bolts.
n/a though. if i were running boost, i'd upgrade the rods.
