ok... since my b16 block is going to need to be rebuilt in the near future anyways, i'm thinking of just biting the bullet and going ls/vtec. i want to run .25 over ctr pistons on eagle rods, but i think the cr is going to be somewhere around 12:1... is that going to be too much for the stock sleeves? also, what kind of rev-limit can i expect (don't want to be cracking sleeves or putting rods through blocks, etc.)?
