Well technically you have a P38-type diff, which is basically a "snub nose" rover diff.

They are a very poor design (as confirmed by the Ashcrofts - the leading experts on rover drivelines). In a 130 that tows regularly, it is not a question of if it will fail, but when.

Your money would be better spent swapping the rear axle for a salisbury type, as fitted to defenders until 2002/2003.

I have the BAS remap and find very good. Pete Bell will custom write a map for needs and vehicle specs. BAS writes his maps to stay in the safe range for EGT's, but a gage is still good idea.

I also use a AliSport intercooler as recommended by BAS, with silicon TF hoses. In addition I also have a decat pipe and centre muffler removal pipe.

All the mods work very well together, but I think the intercooler is of the biggest benifit.

You hear lots of "doom n gloom" prediction on your rear diff, and while I do agree that Ashcroft have stated they are a poor design. I have not had any issues with mine. I tow a off road van and do my shre of off roading.

If you go for a locker make it an Ashcroft, but it will not help with diff strength or your towing ability unless you towing extreme off road.

I agree with drover regarding the diff, I'm on my second puma, tow 3.5 ton for work 3-4 days a week, the ute is always heavily loaded, and I drive it pretty hard off road, no diff issues, no noises, no doom and gloom, if it breaks fix it then, if your in the scrub and it breaks, it's not the end of the world, you can still get home..remember that these vehicles are designed to take a fair amount of punishment before they break..trust me!

So Drover, if you did it again is there anything you would leave out. I've got a autologic remap and am waiting on my Alisport intercooler (have the TF hoses already as I had a hose let go). I also tow for owrk and an off road van plus do 4WD challenge events - no probs with diff so far touch wood (he says while touchinghis forehead...) thanks

A locking diff will make no difference whatsoever to power, it's purpose is to apply the power that you do have to both wheels in a situation where the vehicle is not moving due to a loss of grip.
In my current shopping for a 130, the owner of one that I looked at had fitted a 3" exhaust system, said it made a big difference to power and driveability. My short test drive was not enough to confirm or deny.

Hey Marty,

Happy with all the mods (exhaust, map and intercooler) and would certainly do it all again.

Iam however cautious of looking after my engine and don't like having it pushing maximum power.

I use a have couple of maps loaded on my tuning device. Currently I just run a stock map with EGR closed, speed limiter removed. This combo is nice, releases extra power with causing much extra strain and keeps the EGT's low.

Cheers

Thanks guys,

So at this stage I'm looking at the remap, IC and hoses from BAS... Still considering the rear locker as I'm planning on towing on sand a bit (condsidering the simpson as well) and thinking more along the lines of avoiding losing traction as much as possible with the extra weight behind me.

Drover, where did you get the decat and centre muffler pipes? Is this something that any exhaust shop can do? Is it something that is a simple bolt-out / in job?

Sorry for all the questions, (I did search) but this grasshopper has much to learn
