As above
Looking to convert my 3.2 auto to a manual.
I have a pfl manual breaker on the side of the house so before I wheel it off, what can I remove and what do I need ?

Dont forget the Diff, and Prop (I think), as just posted in Dans 'In need of a Diesel; thread. ;)

.... and what do I need ?
Talk to 2woody aka Stu ;)

no need dif as 3.2 auto its 3.9

Chat with Jamesv6, he did the conversion on his old mv6 auto to manual :y

you could give me a call as well....
I'm just doing my eleventh autoectomy now !

Thanks for the info lads.
Must admit, I didn't see the guide BUT its easier to talk to folks who have done it themselves :)
Quick question about the 3.7 / 3.9 diffs.
I know the car will get off the line a little quicker with the 3.9 and it will offset the extra weight of the lpg tank :)
What is the difference in mpg between the 2 diffs in the real world ?
Anybody run both on there cars who could tell me ?

Hi Stu
We had a chat last year before the world turned to shit :)
Not forgotten mate :)

If we just forget about Auto boxes for the minute as its a bit more important to get the ratios right so that the Auto box locks up at the correct Torque and Speed. Asfor the Manual Ive run Manual V6's with both 3.7 and 3.9 Diffs, both were ex Plod so the speedo will be fairly accurate compared to standard which generally read around 3 mph higher at Motorway speeds.
Manual with the 3.7 is the standard set up so on a 70 mph run your doing around 2600 rpm in 5th, which equates to about the same as an Auto with a 3.9 diff. So expect normal MPG figures of the car.
Manual with the 3.9 fitted, does feel a bit more lively off the mark, but not by much, mpg wise when pottering at slow speeds theres not much in it, however when sat at the same 70 mph run your doing 3000 rpm in 5th, so simple maths is going to tell you your going to be down on mpg on the same constant run, in fact I would also say it doesn't feel right you think you need to change up another gear if your used to driving V6's.
Bearing in mind, your planning to change from an Auto to Manual in order to achieve better mpg economy, I would say its important to get the right diff ratio (3.7) in there.
As said on the other post if you feel like experimenting to get a bit more mpg over the norm, why not fit a 3.45 Diff from a Diesel, admittedly you may loose a tad on acceleration but you still got 5 gears to play with as a work around and would expect greater mpg improvements on a run, haven't calculated it but reckon your be doing around 2200 rpm at 70 in Top, I reckon the Torque of a 3.2 would be good enough to cope with a 3.45 but have never dont it myself. Would be interesting to see the results of this though.

Thanks for all that Chris :y
I want to keep the car but can't live with 16 mpg on lpg :'(
Not when I never got less then 23 mpg with the 3ltr.
And that was using the TheBoy style of driving ;D ;D
Just got to do the numbers now and hope everybody pays me :y

obviously if you want acceleration, 3.9 , and if you are after mpg 3.7..
but I wouldnt go for 3.7 personally..

I tried that and there not much difference tbh

not much is how much ? ;D :y

you don't have to do the 3.7 at the same time. You could always do the manual first and change the diff if you decide you need it.
I have a 3.2 still with a 4.2 diff in it and its a hoot 8)
-
manuals are completely different beasts than an auto.. dont hurry for the diff.. you may feel the need for an lsd because you will have hard times controlling the back of car.. :) esp in a rainy country :o

I'll bet ;D the car is a totally different animal above 4k rpm in the 2nd, 3rd and 4th... a very effective way to get from A to B, especially when the suspension is sorted :y

....... but don't look at the instantaneous fuel flow or the fuel gauge ...... ;D ;D ;D

;D ;D ;D Driving it like that, you're having too much fun to think about fuel economy, let alone care... :y

I had this set up on my 3.2 with LSD too and must say its nice to drive round town or if you do track day, down side 4.22 diff its top speed on each gear
