Good spare parts from other cars for P6

Hi,
Looking to start a resto project soon, and thinking about possible spare parts.
I live in Portugal so prices aren't like the UK....
Are there parts that exist from other manufacturers/models that will bolt on to the P6 V8?
Things like rear diff, auto gearbox (mine is 3 speed auto box, wouldnt mind a 4 speed auto box instead?), dirveshaft, rear axle etc.

Cheers
 
diff - you're looking at jaguar really if you want to change it i think.

For autoboxes check out Warren's thread on the ZF4HP22. It is on range rovers, bmws and ldv trucks.... but be careful which one you choose. It's all on Warren's thread...

Rich is that a 4 speed auto instead of the 3 speed auto I have at the moment? Apart from the extra gear, does it give better torque/power through the ratios?
Would I need to do any modifications to the car at all to take this gearbox?

Cheers

Have a read of Warren's thread!

Gearboxes can't give better torque / power - it's the engine does that.

Yes it's a 4 speed auto with lock up on top ( and I think sometimes third?). The first three ratios are identical to the borg-warner, top is then an overdrive ratio identical to fifth in the LT77.

Reminds me, I must sit down and put in some effort on the sticky thread. However pretty much everything is in the general ZF thread, it's just a bit randomly spread around.

So if the first 3 are the same as the stock 3 speed auto, there isnt any real gains (when I meant more torque I thought the ratios were different allowing for more pull through the gears etc). I would only opt for the 4 speed if the ratios were different which gave better acceleration. I'm not looking to top speed so the 3 speed is probably OK.
Are the Borg Warner (assuming thats the one I have) robust? Mine was stood still for 30 years, all I did was fill the transmission up with fluid and thats it!

By the way, whats lock up on top?
 
Lock up is where the torque convertor is locked, so that the gearbox behaves the same way as a manual box with no slip.

Borg-Warner boxes aren't bad - but they can be ruined in a matter of days by putting the wrong fluid in them. Modern fluids destroy the band material. Check out the sticky at the top of the transmissions section.

I beg to differ. The real gain is that fourth gear and lockup torque converter. My engine is now about 1000 rpm slower at NZ's national open road speed limit. The benefits are enormous in terms of refinement and (probably, when I get my leaking fuel pump sorted) fuel economy. The ZF is also much smoother than the BW, and much more responsive. I wouldn't have the foggiest idea what it's all done for the car's top speed, but it is a totally different open road cruiser now. However that's what I was looking for - the car already accelerates fast enough for me - and I've achieved it. Perhaps if acceleration is your holy grail you should be considering a manual conversion?

If you're after acceleration surely fitting the lower 3.54 ratio diff unit from a 2000 or 2200 would give you that, and it would be a direct swap with what you've already got. Only problem would be the engine revving higher at cruising speeds, but fitting an overdrive gearbox like the ZF or a manual like an LT77 would help with that issue.
 
You can always get hold of a jag 3.54 diff if planning a large increase in torque/power :wink:

arent the 4 cylinder diffs weaker than the v8 ones though?

I think the differential inside is only 2 pin on the four cylinder, 4 pin on the V8, but I guess the parts are interchangeble to make a 4 pin 3.54 diff unit, I'm sure someone can confirm this.

Also available in other ratios and optionally LSD 8) (downside is new mounts, propshaft and driveshafts need fabricating) or swap the complete Jaguar IRS in (again more custom fabrication required)
 
OK, so a diff from a 2000 and the ZF 4 speed auto seems to be a very possible swap (Im all for straight swaps, I'm not too keen on huge modifications, especially as my gearbox/suspension knowledge is limited - for now!).

Im not looking for distance trips, more like sunny drives through the coastal hills here outside of Lisbon (Portugal). I'm happiest at the lights blipping the throttle and watching people's head turn....OK OK and maybe a few blasts! I just love 'being' in the car!
