Good clarification P3nGoo1n.

Since we are on the subject, does the OS Giken require any modifications or additional parts for a 6mt open/diff?

The OSG diff was actually made for open diff cars. I THINK that means you don't have to buy the extra stub shaft assembly but I'm really not sure since my car had the VLSD. I'd really like to find out so I can add it onto my review for everyone's record.

Thanks bro, i did ask that same question to Mike at GTM over email a few months back and he told me that it did not need the stub shaft assembly just like you mention but it would be nice for someone to do a review of it to have more info or probably i'm gonna have to get myself one and do a review!

Everything else being the same, it should be pretty straightforward. The normal stuff still applies such as new carrier bearings and diff bushings.

Comparatively speaking, what's the (general) cost of a Quaife diff? What does "$100s less " actually mean...? In dP3NGU1N's write-up he mentioned his all-completed project was somewhere around $2500. I'm not sure if that's worth the cost for a weekend fun car, DD, a few days on the track here and there car. I'm not against performance parts, but a purpose built racecar I'm building not. ;-)

Thanks again for all the insight and PMs too guys!

TRJ,
here is my Quaife invoice

1 x Quaife Differential = $1,228.00
Model Base 6MT
Additional Parts Stub Axle Flange
___________________________
1 x Nismo Differential Cover = $139.00
___________________________
1 x OEM Side Bearings and Seals for 370Z = $130.00

I had VLSD so had to add stub axle

Install cost should be similar.($400.00 at local speed shop for mine)

I was just referring to base prices, not extra parts and install costs. I don't have an LSD just trying to do some basic research from what I've seen other members run to help you out. You've got dp3ngu1n's total for the Giken plus surfdogs for the quaife. It looks like either way it'll be over at least 1500 with the install. Again gotta figure out what you want from a DD or weekend warrior car. Those guys will be able to tell you their experiences I can't. But I can say it won't be a cheap upgrade so just keep it in mind, I looked into it a little while ago and just couldn't justify the cost right now. But that's my choice, I've just been putting funds towards other parts of my car

Here's the "base" prices I was referring to

Quaife base price without anything else is 1100, Giken is 1600

Basing those off of here: Quaife Differential

Yeah. How much is quaife oil or can you use any brand? OSG oil was expensive at about $70...

Differential bushing was another $90

VLSD stub axle - I got lucky and purchased someone's used diff and got the whole thing for $100 (The assembly itself from nissan is something like $140).

Add all of these things together you're looking at $530 in parts alone OTHER than the LSD itself. (Though I think you can actually reuse the bushings, but why would you want to?) $500 was what I paid in labor. All things considered an LSD is at least $2000 even for the most frugal solution.

A Quaife is a gear (helical gear actually) type diff and so does not require special oil. It generates much less heat and is lower maintenance in the long Run.
