I remember reading that the LS/VTec you guys did cracked a cyclinder wall when you guys raced it but what exactly happen and why did it happen. If I'm right you guys were pushing like w 10-12PSi with a kind of built motor... I didn't think 10-12 was that much or correct me if I'm wrong about any of the above things. I'm just woundering cause after I finish my turbo ZC project ( I almost finishing now ) I'd like to switch and go with a CR-VTec or LS/VTec since I'm done and come to known alot about the ZC's and want to try my hands at B series. What can I do or what can be done to prevent something like that happening or was it just a freak accident.

they are putting the head onto a b20 block now.

Nah I meant what caused the walls to crack and waht could be done to prevent such a thing hapening besides sleeving the piston walls ? Or like I said was it just a freak thing that happened ? Thanks... just curious.

ummmmm... i think about 14lbs. of boost cracked the block, he just had the stock ls internals in the block

OOOOOOHHHHHHHHHHH..... that makes alot more sense. I thought they had forged pistons, rods, and all that good stuff.

Stock block, stock pistons, stock rods, etc... stock stock

I pushed it a tad high, it could have done more on stock internals, but my car was only tuned for 12psi. Detonation killed the block, not weak internals.

Cool thanks... it all makes alittle more sense now cause I thought it was fully built.
