Sorry to post this in a 4g forum, but i didnt see an appropriate category for my following questions. If it needs to be moved, i have no complaints LOL. At any rate, Im in a situation where someone i know has a 98 gs 420A motor. He bought a hahn super 16 turbo kit for his car. One opinion was, the way the 420s are made, they can handle more power... any truth to that? safe levels of boost? Any way to go higher boost without engine rebuild? Any information on this topic would be appreciated.. my AIM sn is jclp69 if anyone is willing to talk to me about this in a conversation sense. Thanks a lot!
 
You'll have to rebuild sooner or later. I just put my kit on, and I blew it up already. I suggest replacing the head gasket before turboing. Get a good MLS head gasket
