I plan on building a lsvtec motor, and was wondering if LS rods are good for 9000 rpms. I'm using Integra type r pistons, micro polished crank, blueprinted and balanced, arp rod and head bolts.

 

i have a very similar setup except my ls rods are shot peened.

I'm setting my limiter to 8200 lol. But then again I think thats pretty conservative

 

with the rod bolts it might be, but i personally wouldnt trust them. 9 grand is really up there

 

buddy had lsvtec turbo with 10 psi shiftin anywhere from 9 to 10k and ony thing done to the motor was arp connecting rod bolts

BS.
his stock head / train can't handle 10k

Your fired get out of my state.

I have ls rods shotpeened polished and ARP bolts 8500
9K maybe with full balanced bottom end still i'd keep to 8500 or less.

 

ace come down here to bethlehem and u can go for a ride cuz last thing people call me is a bullshitter

 

and im gettin my motor built right now stock ls rods plan on shiftin anywhere from 9-9800 is the rev limiter in like 2 3 weeks

this is why ls/vtec die, hte rs ratio sucks ***, the speed of the piston is insane i hope u relieze at 10k on an ls the piston is moving faster than a b16a at 10k, the valves should of floated by now .

i call teh bs or at least this car only has 200 miles on it, constant 10k on a stock ls vtec = certain death bottom line.

what do you mean by built? stock rebuild? i dont understand...a "build" usually involves some kind of internal upgrade. anyways, if you paln on revving that far on stock internals, plan on buying another rebuil kit...and a new head.

*edit* and just beacause you CAN rev to 9k doesnt mean youre making power to 9k. if you did, honda woulda set the rev limiter there...

 

If you are looking to get a motor to 9k get a gsr or a b16, you ls/vtec won't last at that...whats a stock ls 7200, i don't remeber off the top of my head but with out changing oil pump water pump rod bolts you really shouldn't rev it over that..with those modse that just makes it a little safer to...don't gsr blocks have extra oil squirts to help with the higher rpms? Honestly if you want a motor that will rev up there just get a gsr and build that...i know easier said than done...I am building a ls vtec but i am only doing that to have a better flowing head for boost, anyways...good luck

 

since the discussion is up i guess ill go ahead and ask instead of making another topic. i have a couple of ls bottom ends just sitting around. id like to use them once i finally get my car turboed (b16). if i use the ls block and buy a gsr crank shaft and maybe something along the lines of golden eagle rods and pistons would the bottom end be able to go to 9k then? with the forged internals i don't need the oil squirters do i? maybe some of you lsvtec guys can chime in and help me out.

i'll get right on it

 

just buy real rods. you're building your motor. it's already apart. if you can't afford to build it "right" then don't build it at all. not that an ls/vtec would last revving that high anyway...

on a side note... shot peened ls rods are pretty decent if you are too poor and/or cheap to buy real rods.

 

A trusted import mechanic around here had a b20 with an ITR head/pistons, but otherwise stock. He would beat the **** out of it daily, shifting at around 9k (ex tach goes to 8k iirc) - no problems for a year (or maybe more). It was killed either by a bent rod or a spun bearing (which is caused by deforming rods).

Cheaper forged rods are only $250-350, why would you risk it?

 

I take my LS rods to 8200 with no problems. I have a fully balanced B18A bottom end, with ARP rod bolts. I plan on going to 8500 or so with ITR cams when I get them.

stock bottom end, all new bearing, water pump oil pump, TB, jun dual spring skunk stg 2 cams,,,a lil more but mild build, stock botttom end and i plan on revvin it 9 or more

 

maybe i should up my redline then?

I have shot peened ls rods, arp bolts, new bearings and a fully balanced rotating assembly from crank pulley to pressure plate

 

and b4 anyone says anything i do plan on gettin rods shotpeened, and already have arp rod bolts

 

i have a fully built/balanced/blueprinted ls/vtec w/ eagle rods n je pistons, and mine doesnt even see over 8k. again im going turbo, so theres not too much to worry about over 8k for me anyways, but to the original poster, i wouldnt rev my stock bottom ls/vtec over 7800-8000 at the most, as stated above, rod stroke ratio isnt very good in these bottoms, and unless you got stronger rods/bolts AND a balanced bottom, i wouldnt do it...of course it is your time and your money you'll be wasting when you blow it... good luck anyways...

 

Why in the holy moly are some of you guys revving to 9-10K. The damn motor isn't making power up their so why in the hell even do it.
At the shop I used to work at we had a b16 with skunk2 stage 2 in and the motor stoped making power at around 8700 if I remember correctly. It just doesn't make sense fellows but its your money and your motor so............
