Hey dude, are you still going to go for the manual with a crow cam??? If so, then I would STRONGLY advise against a 3.45...

The crow cam doesn't have all that much up top (without head work), and coupled with a manual box, you're gonna spend your entire life changing gears!!! If I were you, I'd go for a 3.23 at the most (which you might find you've already got).


Otherwise, in answer to your questions:

Yes, the XR6 diff will fit.

Last time I got quotes - ratio change was $400 and rebuild (may be required when getting ratio change) was $450. But this was quite some time ago...
Otherwise, you could spend a liftime hunting at the wreckers.

Ok thanx dave, yep manual and crow cam and engine rebuild are being saved up for as we speak, but as i said i kinda trashed the diff, but if the 3.23 lsd will give me the maximun and most reliable power delivery with those mods I mose well just get it reco'd. :)

Hey Thanatos!

What sort of crow cam are we talking about here? Because I have the stage 2 cam in mine with pacemakers, 3 inch cat and 2.5inch exhaust system, and it revs like a bastard compared to the stocker!

I would love to have a 3.45 and 5 speed in my manual! It would haul!

Friggin auto with two second gears! >:(

:)

Sorry, I probably should have explained myself better...

I am talking about the stage 2 cam. Mine also 'revs like a bastard compared to the stocker', but what I was trying to illustrate is that, whilst it revs hard, the power increase up top isn't anywhere near the increase down low... So therefore, it would be a good idea to harness some of this low down torque, instead of wasting it all by fitting a ratio that is too short. And, when coupled with a 5 speed, I think excessive wheelspin would be a serious problem during a hard launch (I'm bordering on that now!).

Hope this explains what I meant a little better!


Dave
