EverRude Posted July 19, 2008 Share Posted July 19, 2008 I'm currently swapping the L28ET motor from the 81 ZX into my 75 280Z. The ZX is an automatic ofcourse so I don't need the tranny. Should I try to save the rearend for later? Or just scrap it with the rest of the body. It could be a long time before I would use it and it'll take up precious space and likely need a rebuild before it could be used (167k miles on it). The ZX could bring about $150 scrapped it I tow it in myself. If I remove that rearend I have to pretty much give the car to an auto scrapper just to get them to haul it off with no rear suspension. So basically it's like paying $150 for a rearend I don't need. Ofcourse I haven't driven the 75 Z yet. Could be that R200 is trashed.... If I had more money and space it would be a no-brainer. But with limited space I have to set priorities. That $150 could be a new brake bootser I'll probably need or some sheet metal I definitely need.... Is the turbo rearend worth the cost, so save for later? Or easy to get later, so scrap it? Oppinions? Thanks Quote Link to comment Share on other sites More sharing options...
naviathan Posted July 19, 2008 Share Posted July 19, 2008 Not for an automatic rear. Those are R180s and really aren't worth much. Although you can remove the diff and still be able to tow the carcass to the scrap yard without it. Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted July 19, 2008 Share Posted July 19, 2008 the ZXT's all got R200s iirc. It will be the same ratio as your 75, so Id just scrap it Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted July 19, 2008 Share Posted July 19, 2008 i would save it-in about 2 or 3 years of hard driving the spider gears get sloppy in the diff if you really use your car hard.plus it has a bigger pinion flange to build a heavy duty driveshaft with.i would probably save the drive shaft to-it has bigger u joints.most drive line shops will shorten and rebalence for around $100 or less.i have seen 280zxt powered cars waste the drive shafts at the drag strip with the small original z car driveshaft.

EverRude Posted July 19, 2008 Author Share Posted July 19, 2008 I didn't think about the fact I could remove the differential and still keep the rear end intact. I may just do that. Thanks guys. Quote Link to comment Share on other sites More sharing options...
z or bust Posted July 20, 2008 Share Posted July 20, 2008 If you dont want it I need one.... Quote Link to comment Share on other sites More sharing options...
roger.svoboda Posted July 23, 2008 Share Posted July 23, 2008 might want to grab the cv joint half shafts for use better than the u joint model. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted July 24, 2008 Share Posted July 24, 2008 If you don't save it, at least save the flange on the input shaft of the diff. It's a different size for 280zx turbo and it might come in handy. Quote Link to comment Share on other sites More sharing options...
