I have a 1990 non-turbo coupe with a manual trans. I believe this is the lightest chassis for the Z32. Without twin turbos, intercoolers, HICAS, leather, airbags, iron brake calipers, thicker rotors, etc - the curb weight is only in the 3,300 ballpark. I hope to reach 3,000 lbs by removing the HVAC and all related accessories, much of the interior, exhaust, stereo, cruise control, wiper & antenna assemblies, spare tire/jack, and going with lighter seats & suspension. Also considering the LS1 is roughly 100 lbs lighter than the VG30DE, I expect to see a 200 lb loss with the aforementioned items. Here's a great link showing where & how to shed extra L-B's: http://www.twinturbo.net/nissan/300zx/forums/technical/view/1065404/Weight-Reductions-101---Part-1-The-Basics.html
