heard a rumor that g35 rear may fit a G50

[jamesmost]

anyone know if true?G35 gearing?

[jtesensky]

You wouldn't want the G35 gearing on a G50, it's alot longer (due to the 5 & 6 transmission gears) I believe it is a 3.23 ratio (auto trans), I know that the G50 is a better set up for off the line acceleration. You're best bet is still the N/A Z32 4.08 rear end. I wan to know if the 4.08 will work on the G35, now that would be interesting...

[jtesensky]

BTW, a '90-'93 1st gear start Q45 would smoke a G35 off the line, I would put money on it...

[jamesmost]

beg to differ those g35 fly off the line90-93 - has the same rear as 94-96the difference is 90-93 has a taller first gear 58 tooth94-96 has a 52 tooth (or is it the other way around/)

I own one, the automatics are nothing special up until about 4K RPM in 1st gear...

i hear u the coupe i drove was a manual transmission apples to oranges

OOOOOHHHHHH! a 3.23:1 rear!!!! Look out 200 MPH!!!

OOOOOHHHHHH! a 3.23:1 rear!!!! Look out 200 MPH!!!

With 0-60 in 30 sec

With a drop to 3.23 from 3.538 [9%].............the TCU speed vs gear vs load software would be way off .........unlikely that the engine [any used Q engine] could provide enough torque at reduced rpm 50mph AC on in overdrive would be a trip------ LUGG CITY [1665 > 1515 rpm]..............constant downshifting without removing 9% of the vehicle weight.

Changing 3rd gear x diff ratio would raise max 3rd gear speed to 157 mph unlikely that the reduced 4th ratio could maintain that speed after a shift as the HP would be lower [~~5%] at 4750 rpm vs 5230

The G35 uses an R210 differential, same as the Z33.

G50's have R200s.

For the price I'd stick to the R200 units.

I have the definititive answer. I just spent the day digging through rear subframes. I compared J30, Q45 (both G50 and Y33), G35 and 350z.

The G35/350Z rears that I saw were R200 diffs. Just like the others. They WERE NOT R230 diffs like the 300zx turbo.

They DO have the 6-bolt flange like G50 Q45s, rather than the 5-bolt flange of the other infinitis and NA Z32. These are the evenly spaced 6-bolt flange, not the "3 pairs of two" flange used on 240sx and some others. BUT, they have ABS rings on both flanges, so you would have to use them on a car with TCS or use TCS axles.

The cast iron R200 hogshead is the same in all these cars (Q45, G30, J30, 350Z) so the front diff mount is the same. The input flange appears to be the same as the G50 also but I wasn't able to check if they were the same.

The G35/350z diff cover has one mounting stud versus two for the rest of the cars.The location of the one mount is the same as the right side one of the double mount on the rest of the cars (weird).

Nothing about the suspension geometry, subframe, strut mounts or anything else is similar to the early RWD Nissans. In case you've never seen one, it's made of hydraulically formed aluminum sheet with aluminum control arms and is just beautiful. It's a shame it won't bolt into any of the earlier cars.

Good info robert!
