it does work but save up for some sleeves. Check out erl performance they have the best block and support
yeah i think i might just save the extra money and sleeve itdont use one, at that power level if it detonates the stock sleeve it gone regardless. Just get it sleeved and dont worry about it.
Well, first you have to change "b20forlife" to "kseries4life" then I am sure you can get a block.ok so i been wanting to put my built motor in my car. its stock sleeves with wisco 9. 86.5mm pistons and pauter rods. now since its stock sleeves and i want to push like 650whp will a block guard help or is it not even not worth the extra 100 bucks
