Anyone know how much a used rear 5-sp diff would cost. I hear that will give me a little more low end torque with my auto. Is this a hard thing to swith out? Can you just buy new gears...is that easier?

 

yes you can just buy the new gears... .probably cheaper than most full diffs...

 

how much...100bucks?

 

you can probably find it for around that price, just gotta look around

 

what about the high end? If you are on the hwy are you going to run at like 4k rpms? Seems like that would make for shorter engine life.

 

eh, not sure, there is a spreadsheet on another thread that you could see where you would be at, it definately wouldn't be that high...

 

The Auto's 4th gear is slightly taller than 5th in the manual box so even with 4.10 gear on an auto you will be running lower rpms the frwy than a 5spd.

 

Yeah, you can get a used 4.1 ring and pinion for about that much, but we have to assume he's going have someone put it in - $500+ in labor at least? Of course, you being the thrifty automotive equivilant of Bob Villa, you probably over looked that.

 

lol, hey now be nice.
