Guest Anonymous Posted February 16, 2000 Share Posted February 16, 2000 right now i am in a "collection of parts" stage before i do the v8 swap. i was just wondering what kind of rear everyone has. i have heard that a stock z rear can take about 400hp and anything beyond that is asking for trouble. I plan to have a 500hp 350 with about a 300hp nos system. what do you guys recomend? has anyone ever heard of or tried to use a corvette rear? i heard that independant suspension hooks up good. thanks Quote Link to comment Share on other sites More sharing options...
Mikelly Posted February 16, 2000 Share Posted February 16, 2000 Shannon, What are you intending to do with the car? Obviously you are gonna drag race it some, but is it gonna be a street car? Seems like 500HP +300 shot of nitros is a bit high. If you are focused on drag racing, then get a 12bolt chevy or Ford 9Inch rear, but be prepared.... It will cost a bunch to put one in correctly. I personally am using a 1988300zxT rear with LSD and 3:7 gears in my 500+ HP 383 stroker.

MYRON Posted February 16, 2000 Share Posted February 16, 2000 Shannon, I think that an R200 datsun diff. is pretty damn tuff, its the ujounts and half shafts that may give you the most of your problems. If your planning on spraying your 500+ hp motor with a big shot I strongly suggest the you go with a solid rear axle. With that king of HP any racetrack will ask you to leave after your first pass with the independent rear end. And you better put in a good cage as well Myron Quote Link to comment Share on other sites More sharing options...
Guest Locutus Posted February 16, 2000 Share Posted February 16, 2000 How can I find out which rear end I have. Its a 79 280ZX with a 5spd manual. I was planning on replacing all my ujoints. Anything else I should replace while I got the car up. Mike Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 16, 2000 Share Posted February 16, 2000 I've read that anything over 450hp is well beyond any Datsun gear. I'm going to be running around 425hp in my 240Z and am installing a full spaceframe subframe, integrated rollbar, and a Ford 9" posi rear. I'm straying from the pack after this point because I'm keeping my IRS by installing Corvette half shafts with Ford input ends. It will then connect to the datsun rear struts with modified stub shafts. This will be a beefy system that will be able to handle anything I will throw at it. With 800+hp at your disposal you should consider nothing less than a solid ford 9" rear. I'm assuming this will be a "dragstrip only" car...if I'm correct in that assumption than I suggest installing a spool since any spider gears on any differential will also explode spontaneously. Good luck...this is definately a crazy proposition...just the way we like it here!!!! SpencZ Quote Link to comment Share on other sites More sharing options...
pparaska Posted February 17, 2000 Share Posted February 17, 2000 Shannon, I'm not sure which car you have (and by that I mean which stub axles (240/early-260 or late-260/280) because the earlier ones are a bit more prone to break with lots of torque, big sticky tires and clutch drops. The later stub axle gives a little more strength. BTW, the 280ZXT stub axles are the same size where they usually break, at the transition from the splines to the bearing race surface. Jim Biondo is using C3 Vette stub axles, stock vette bearings and custom outer race spacers to put a stout aftermarket billet piece in the stock hub carrier. BTW, Jim met a guy down in the southeast US somewhere that has a 700 hp Supra Turbo engine and tranny in a 240Z. He has been having trouble with the CV halfshafts. Seems the ball bearings in the tripod joints are trying to force their way through the outer tulip casing on the inner CV shaft joint. Jim is considering a bolt-on reinforcing band or having them carbon fiber wrapped on a filament winding maching to stiffen this area on his car, although he hasn't seen the problem with only 550 hp . Man, there's always a weak link if you keep upping the power ! ------------------ Pete Paraska - 73 540Z - Marathon Z Project - pparaska@tidalwave.net">pparaska@tidalwave.net - Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 17, 2000 Share Posted February 17, 2000 Shannon, I've made a few posts on the same subject recently. I'm starting a drag Z project very soon. I will be using a ford 9" w/ powerglide tranny (4.56 gears I think) with a 383 stroker. From what everyone says this will be a strong combo. If you want to read the post "Brute Speed Z Project" it might help a little bit.. Thom Quote Link to comment Share on other sites More sharing options...
Cyind Posted August 23, 2000 Share Posted August 23, 2000 Shannon, I have a vette rearend in my 450+ HP and it hooks up strong and I can still corner also. 700R4 will get rubber in 1st, 2nd and 3rd... how sweet it is... ------------------ Z U V8ter http://cyind.com Rspencer@satx.rr.com Quote Link to comment Share on other sites More sharing options...
pparaska Posted August 23, 2000 Share Posted August 23, 2000 Cyind, please give us the details of the Vette rear in your car, how it was done, etc. I know there was a place down that way it Texas years ago (Conversion Concepts?) that had a catalog where they said they were working on a Vette rear end swap into the early Z. Are you affiliated with that bunch?
