How much boost LQ4 w/ 243's
How much boost LQ4 w/ 243's Stock bottom end LQ4, Katech rod bolts. Has an EPS grind 231/234 .617/.612 112 lsa, would probably end up changing out the cam. Has stage 2.5 PRC 243's with the stock sized valves and PRC .650 springs. Top end is a FAST 102LSXR and NW102 tb. ARP head bolts and standard 6.0L GM MLS headgaskets.
Basically wondering how much boost this setup could handle and if I was going to go the turbo route with probably a tc76, am I going to be better off selling off the 243's and getting a set of 317's.
Ran the new setup for the first time Saturday and was running consistant 11.2-11.3 with consistant 1.5x 60' times. More or less just looking to see how much boost my setup could take before I really get too excited over doing a turbo build down the road.
I've searched for LQ4 w/243 head setups but looks like no one is really as stubborn as me. I'd just hate to have to sell them and get a different set of heads worked over
Thanks for any input
