Picked up a 1990 S13, unmolested. Currently working a coolant/head gasket/cracked head or block issue at the moment. Bought last year in North Carolina, had a seized engine. Bought another KA24E off eBay and she's smoking white out the tailpipe like crazy. Installed new head gasket, torqued down properly and everything, still smokes. Points to a crack. This sucks. Not giving up! I had a 1991 S13 back in the late 90's after joining the Air Force and I will get this baby back to operating again! Keeping her stock and most likely will get an updated paint job at some point.
