Cobra_Tim Posted January 20, 2008 Share Posted January 20, 2008 Anyone know if this is a viable option for us poor suckers stuck with R180 diffs? I called the company and they say they get some orders from Zcar folks Down Under but never any orders state side. The were unsure if it fits our diffs. This would be for an ITS car BTW. *edit* http://www.purenissan.com/r180_lsd1.htm Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted January 20, 2008 Share Posted January 20, 2008 I have never heard of this company. Do they have a website you could link? Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted January 20, 2008 Author Share Posted January 20, 2008 Sorry I forgot the link They say its for the front diff on a 4x4 hard body pickup. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 20, 2008 Share Posted January 20, 2008 That is the Nissan LSD. There was a change in the ring gear size, I think it happened in the mid 70s (76???) and after this the ID of the ring gear changed. This has been discussed before but it's probably been 3 or 4 years. You can look it up. So the issue is that you'd need to have the later R180 for this to fit. Also, the factory that manufactures these supposedly had a fire and there are no more left and the tooling is destroyed (this is as of last fall or so). I'd try to order one and see if they come back telling you it is NLA. Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted January 20, 2008 Author Share Posted January 20, 2008 Right now we have a 4:11 from the front of a 720 pickup in the car. I know about the ring gear sizing change so as long as we had all the proper ring and pinion sets it would work just fine right? Also, we don’t have any race worthy ratios in the older style ring gear ANYWAYS. SO all Id have to do is get a 3.7 and a 3.9 from an old maxima and Id have the 3 ideal ratios in the later style that would fit that LSD unit and it would be 100% ITS legal. Correct? The guy on the phone told me he had these in stock ready to ship in a day. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 20, 2008 Share Posted January 20, 2008 I can't tell you about ITS legal. I'd imagine it would be legal but some sniveler might know how to determine which are the later ones and say that you're using a truck diff in your ITS car. Not sure if that would be an issue or not. If they have them in stock, I believe that would what you're proposing would work. I know no reason why it wouldn't. Quote Link to comment Share on other sites More sharing options...
Careless Posted January 20, 2008 Share Posted January 20, 2008 here's what I got for you: Here are the corresponding part numbers. Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted January 20, 2008 Share Posted January 20, 2008 Wow 6 clutch disks per side... Quote Link to comment Share on other sites More sharing options...
Careless Posted January 20, 2008 Share Posted January 20, 2008 yeah i said the same thing when I looked at it. quite a bit. I think the cusco has 16? pretty tight stuff. This is from the Japanese Nissan Hard body (D21) FAST index. Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted January 20, 2008 Share Posted January 20, 2008 Maybe 16 total? 6 per side already is a bunch. The Powerbrute R200's are 3 per side. I think stock was 1 and 2 friction disks, but don't quote me on that. Wonder if there is an appreciable difference in the torque the R200 clutch units can take compared to the R180. What I mean is what is the equivalent number of R200 disks when compared to the R180 disks. Anyone know the diameter of disks? Quote Link to comment Share on other sites More sharing options...

greenmonster80 Posted January 20, 2008 Share Posted January 20, 2008 I pulled a 4.10 from the 720 yesterday and plan on using it in my SR swap. This really got my attention. Price isn't bad considering brand new parts and modern design. If you get this please post how it installs and works out for you. Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted January 20, 2008 Author Share Posted January 20, 2008 Im not worried about the legality part... this I know wont be a problem as the rules state anything that fits in an un modified, stock housing, is legal. I just want to verify that this will indeed work with the 710/maxima ring gears. Quote Link to comment Share on other sites More sharing options...
