Chaging the Diffs to rangies

MOTORSPORT_SAFETY:
Hi guys

Thanks for all the advice iv decided its probably not worth the expense to do it

As I said with the overdrive and fwh I dont think ill see much of a benefit in doing it.

I have the disel 2 1/4 sorry I think some people got the jist it was a petrol.

As for brakes its getting the setup that was on the 6cyl so are 11" drums on the rear and not too sure whats on front as I have not got that far yet hopefull all things being equal the back will have everything on it except the shoes this time tomorrow in my wisdom I got all forgot to get the normal shoes for the rear though I do have 4 sets of shoes for the fronts so not probs sourcing them in the future lol.

All the best gang if I have any more daft questions ill be sure to ask lol

id stick with what you have got i have got them in my s3 diesel and it only really gets up to speed on the moterway and i have only seen the benifits of them on a long run. the other bit which hasnt been said is choice of tyre type and size if you use any thing biger than a 205/600/235\70 it will be really slow of the mark and even more so with muds

Miniman:
Best thing I ever did to my 88" was get rid of the old tired 2.25D and fit a Perkins 4203 3.3L. Its No more BHP but its packed with tourque. With the engine only reving to 2600rpm you would think its going to be slow but because I have rangie diffs in it will do 60mph flat out and it will stay there up and down hills.

Tikirocker:
I've got a Holden 6cyl 186 in my 88 and have been toying with either a rear Salisbury conversion or the RR axles conversion giving disc brakes and wider track. If I went with the RR option I'd actually swap the 3.45 diffs out and put in the Rover 4.7's to maintain the gearing - running 3.45's make the gearing too tall for low range though it might be ok for h'way but you'd find it tough work pulling hills and anything else unless you had a big motor in there. My Holden 6 cyl has more torque than most standard V8's but I dare not go with 3.54 anyway. Better to stick with 4.7 and get a HRTC conversion which leaves Low Range alone in my case but every case will be different for the driver and vehicle.

Best, Simon.

--- Quote from: "Miniman" --- I have a servo off a 90 and 11" 109 from drums and the brakes are super duper.....

So will 10" on front and 11" on the back be fine or does it need 11" all round :?:  I'm just weighing up the options for a future engine swap as the 2 1/4 diesel is pants IMO. Probably wont be swapped this year but everything else can be uprated first :D
