johnc Posted May 21, 2009 Share Posted May 21, 2009 (edited) Next week my machinist will be cutting one pair of side axles (stub axles) that will fit in the 27 spline 2004/2005 Subaru WRX STi R180 rear CLSDs and 2006 VLSD. The flange end of the these side shafts will bolt up to the stock 240Z halfshafts. This pair is the prototype and will be made from 4140, heat treated, etc. What I need is someone who can test these for me starting in mid-June. That means you must have the Subaru diff in hand (or can get one quickly) and have a running, driving, reliable car that can put some street and track miles on it in a short time. That's a tall order but you'll get to keep these side axles if you follow through and send me feedback, pictures, and measurements.

Just a thought, but you might try asking that guy that did the write up for the Subaru R180 conversion, since he would probably have most of those parts on hand, if not all of them.

mossy74 Posted May 24, 2009 Share Posted May 24, 2009 Sounds good, I'd be very interested, I will be running a mild 327 sbc though so I wonder if the halfshafts and diff will hold up. In saying that the PO ran the standard halfshafts and r180 for 18 years without a problem:confused: Quote Link to comment Share on other sites More sharing options...
SSS-S30 Posted May 26, 2009 Share Posted May 26, 2009 I'll be interested in a set when they become available. Quote Link to comment Share on other sites More sharing options...
Racer Z Posted May 28, 2009 Share Posted May 28, 2009 We might be able to help with the testing. We can drive to you shop to take care of whatever needs to be taken care of. Our 73 240z is drivable and has had some track time as well as still being street legal. We have a Subaru CLSD 27 spline. Quote Link to comment Share on other sites More sharing options...

John , i have got a Subaru 180 diff 4.44 ratio with a gear type ( no plates ) lsd specialist ?? told me that it should be a viscous but its definetly not . I want to use inner CV from Subaru and i made new flanges for the outside to fit 110 diameter Lobro CV without any spacer , i bought the diff but i still not know of witch type and year Subaru it is , Regards Adrian , www.va-motorsport.com Quote Link to comment Share on other sites More sharing options...
johnc Posted May 31, 2009 Author Share Posted May 31, 2009 I don't know what Subaru sold in Europe or Japan. Here in the US they used a CLSD in 2004 and 2005 and a VLSD in 2006 on the STi. The gear ratios are 3:54 and 3:90. Even then I might have those figures wrong. Quote Link to comment Share on other sites More sharing options...

Hi John, the 2006 STI should be CLSD also (like the 04' and 05'). 3.54 ratios are in the 2006 and 2007 STI. 3.90 ratios are in the 2004, 2005, and 2008 STI. Torsen LSDs came in the 2007 and 2008 STI.

John , i found out about the lsd , its a Torsen T2 , the 4.44 is right , you are right about they probably do not have it in the US , Quote Link to comment Share on other sites More sharing options...

johnc Posted August 21, 2009 Author Share Posted August 21, 2009 Got the rough machined prototype and I've welded the shaft to the flange. Next step is more machining, heat treating, final machining, broaching, and case-carburizing. Material is 9310 which is typical for carburized gears.
