Ls Vtec
 

What would an LS Vtec with a B18B bottom and a B16A2 top redline be?

It will be as low as the b18b redline unless you strengthen it so that it can withstand revving higher.

It has Je pistons and eagle rods, but stock crank, and i am quite sure stock sleeves.

The crank doesint realy matter. im pretty shur that u would red line at about 8000 give or take

might wanna balance the rotating assembly and get a gsr crank girdle. just to be safe.

Balancing is very good but u would not need to get a new crank unless u wanna go lighter but stock cranks should be more than strong enough.

i didn't say a new crank, just a girdle from a GSR

without rod bolts i wouldn't go over 7500rpm

all new eagle rods come with what u need. and ur stock crank would be stong enough but I don't think you will make any more power past 7500, so you could go to 8 g's but I don't think its worth it. 7200-7500 would be a good power end and safe area for longer life.

if its using a b16 head it should make power up to 7800 rpm

hey duch, listening to some of the guys in this thread will cost you a lot of money.Don't listen to this bullshit about strengthening the block.Ihad a 90 integra with an ls/vtec.The block never even came out of the car when I put my b16 head on.I beat that car senseless for two years and then I sold it,still running mint.Your redline will be 8200 with most vtec ecu's
