chrismoose17 Posted March 28, 2006 Share Posted March 28, 2006 i have a 79 280zx which had i standerd transmission before the sbc swap, but it has a r-180 rear end. why is this? i have been reading these forums for a long time and it seems like everyone has the same conclusion...all the 280z and zx with a standerd tranny had the r-200. any thoughts would be appreciated Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted March 28, 2006 Share Posted March 28, 2006 It might have the rare 3.36 R-180.... or something like that... Some 79 ZXs had weird rear-end ratios. Mario Quote Link to comment Share on other sites More sharing options...

CruxGNZ Posted March 28, 2006 Share Posted March 28, 2006 What do you plan on doing with the car? What gear ratio do you want? Help us out and we can help you. Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted March 28, 2006 Share Posted March 28, 2006 Don't sweat it Chris. Several guys here have gotten lots of V8 miles out of their R180's, self included. You can get R200's cheap enough and the swap is easy. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted March 28, 2006 Share Posted March 28, 2006 Some MT '75's had R180's also... Quote Link to comment Share on other sites More sharing options...
chrismoose17 Posted March 29, 2006 Author Share Posted March 29, 2006 as far as what i want to do with, i am not really sure many friends of mine are into autox but i really dont think the zx with the sbc will do to well at that. i will most likely do drag race it. as far as that goes what rear end ratios would i need, i want it to have decent acceleration but i will drive it on the interstate occsionally. so i really dont want a really tall gear. i also plan on investing in a limited slip diff, i am just not sure if i want to spend that much money on the r-180. wouldnt it be wiser to spend that little extra on the r-200. i have a 350 sbc w/ edelbrock performer carb and intake, electronic ignition and a 200r4 transmission. maybe that will help with what gear ratio i will need Quote Link to comment Share on other sites More sharing options...
