Guest mofaster Posted February 8, 2006 Share Posted February 8, 2006 I'm putting either a Ram Jet 350 or a screamer of a 327 in my '71 240. I want a rear end that will handle up to 425 lb ft of torque but i want to maintain the independent suspension. How much torque can a properly rebuilt stock rear end take?

desert dog Posted February 8, 2006 Share Posted February 8, 2006 240 axle? Not much. Quote Link to comment Share on other sites More sharing options...
blueovalz Posted February 8, 2006 Share Posted February 8, 2006 A thorough search will net a ton of information and discussion about the R200 (later model Z rear end assembly), as well as the typical modifications using Nissan parts (or others) that are stronger than the OEM set-up. Key words: R200 R230 axle There is just too much to explain even in a long paragraph, but suffice it to say the R200 assembly has held up well behind many HybridsZs, and not as well behind a few others.

dj paul Posted February 8, 2006 Share Posted February 8, 2006 you want an r200 or r230. you can get an r230 out of a q45 and get the stub axles and get some stronger hub assemblies and you should be ok. the rest of the rear suspension is good IMO even tho im going with 240sx rear subframe.

desert dog Posted February 8, 2006 Share Posted February 8, 2006 I thought the Q45 diff was an R200? I am actively looking for a R230, and the only vehcles I know of with that pumpkin are the 300ZXTT and the Armada... No, you will gut an R180 (240Z diff) in fairly short order with V-8 power.
