This is a dublicate post but the first post was in the V8 Chevy area..oops

 

I just want to make sure my info is correct?

 

I have done about a weeks worth of research on this rear diff thing and this is what i have as option...please let me know if i dont have this strait. I know that this has been beaten to death but any help would be nice? I think it would be nice to have the 3.7:1 gearing cuz the t56 final is to tall

 

1st Option-

5th month of 1987 to 1989 300zx cluch type r200

3.7:1

1 set of cv half shafts

1 set of cv adapter plates

easy swap - hard to find!

 

2nd Option

1991 - 1996 300zxtt VLSD type R230

3.7 : 1

2 sets of CV half shafts

1 set new half shafts

Fab front mount

Redrill Mustache Bar

new drive shaft

hard to find

 

3rd Option

1990 - 1997 Q45 (1990 - 1996 300zx NA) VLSD Type R200

3.54 : 1

2 sets of CV half shafts

1 set new half shafts

Fab Front Mount

Redrill Mustache Bar

New Drive Shaft

With stock diameter tires with the 3.70:1 you'll be at 1,500 rpm at 60 mph. With the 3.54:1 you'll be at be at 1,435 rpm. This is not a problem for the LS1. You actually could cruise on the level at 45 MPH in 6th with the 3.54:1 diff with no problems. I've taken mine all the way down to 40 mph and been able to motor along comfortably. It's amazing how quiet it is at idle and how the whole world wakes up when you downshift to second at that speed and nail it.
