I just had I/H/E.. Zex Wet Kit with a purge and heaterI'm worried about the stock rods, I've seen one go through the block on spray. My buddy has a k20 swapped ek that let go before he ever even got a pull out of it. Dyno tuned then went boom lol. I don't remember his shot size though, he may have been on a 100 shot. @datbigdude, did you have a completely stock k20z3 you sprayed for a while there? what kid where you using? I don't mind blowing up my block I'm not sweating pulling it and replacing it, I'll do that in a weekend lol. I just don't want it to blow before I can afford to build a k24 the way I want it done for the overall setup haha.
