Hi all im about to buy a L28E and its in ehhh condition came out of a running 280z from what i was told but hes selling for 100$ and i want to build a motor of my own, i was thinking if i did get it if i where to rering it, new gaskets, new waterpump and things like that, highperformance oilpump, and ms, and full port and polish... would this be good upgrades for at least 200+ hp? is this doable on a somewhat cheap foundation?
