JMortensen Posted December 3, 2008 Share Posted December 3, 2008 They're both L28 engines, but the later motor has dished pistons and the early one has flat tops. You can get about 10.5:1 compression by running the flat tops with the early head, but that is really high compression for pump gas and a lot of people running that combo have to back off the timing to prevent pinging. To make it simple, the parts swap back and forth, but you have a head with a big chamber and flat top pistons on one and a dished piston and smaller chamber on the other.

naviathan Posted December 3, 2008 Share Posted December 3, 2008 Swap the head from the 75 onto the 82 block with a 2mm head gasket and throw on a MegaSquirt for some fun. Or take the time to tune the stock EFI if you want. Quote Link to comment Share on other sites More sharing options...
baby280 Posted December 3, 2008 Author Share Posted December 3, 2008 how about the injectors, fuel rail, and fuel pump can I swap them off my 82 zx and put them on my 75 z? Quote Link to comment Share on other sites More sharing options...
naviathan Posted December 3, 2008 Share Posted December 3, 2008 I'm going to go with yes on this one. i'm pretty sure they're the same injectors. Quote Link to comment Share on other sites More sharing options...
