Mikelly Posted January 10, 2005 Share Posted January 10, 2005 So on Saturday I was in a snit over a stuck line on a hydraulic release bearing on my vette when Jamie rang me up. He was in the area, had just picked up a 300ZX R230 differential and wanted to do a little comparison. He knew I had TWO Q45 differentials I'd gotten from mark Icard, and wanted to sit them side by side to sww how different they are... So I said Sure "I need a break anyway!" I'll post the pics tonight, but there is one thing for sure... These two differentials are ABSOLUTELY different in exterior size. The case on the 300ZX R230 is for sure larger, and accomodates a lot more sensors, including ring gears for ABS. The unit appears to be heavier too! This should resolve any dispute or dicsussion about this topic any further... I know the Q45 has the R230 230mm ring gear, but maybe the difference is in the LSD type or the carrier on the 300ZX unit is larger. Regardless, we now have a definative answer. The 300ZX unit looks physically wider as well, which may impact axle length, which is something to consider when fabricating axles. Pics tonight!

RB26powered74zcar Posted January 10, 2005 Share Posted January 10, 2005 This is good to hear, as really, the best way to put something to rest, is to see it with your own eyes. Great idea Mike... and can't wait to see the pics!! Quote Link to comment Share on other sites More sharing options...

Mikelly Posted January 12, 2005 Author Share Posted January 12, 2005 Well heck... Good question... I don't really know... I'll have to check! Mike Quote Link to comment Share on other sites More sharing options...
mark Posted January 12, 2005 Share Posted January 12, 2005 Mike, If I remember correctly they are from 94 or 95 cars. Not after 95 for sure. Mark Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 13, 2005 Share Posted January 13, 2005 All information that I have is that only the 2nd gen Q's had R230's in them - the 1st gen had R200's. The 3'rd gens have R200 OPEN diffs in them. That said, since I will be turboing a V8, I will get an Armada R230 w/2.98 gears in it...
