as an aside, Force9 axles or Toyota axles may be a cheaper option for guaranteed durability Cheers

Thanks for all the replies and options.

I'm after keeping it as standard as possible but upgrading the weak links in the system. Theres no point in upgrading the drive shafts as you want them to be the weakest pint so you can drive if one breaks. You don't want it going past them and breaking the gearbox!

If the front diff is 2-pin then i'll upgrade that and then look at the LSD front and rear but if its 4-Pin ill leave it as is. No point in replacing it just for LSD. Unless I can't pull away with all the power not being able to go down then I'll need the LSD Very Happy

@Caterham - Yes its having a LS3 V8 fitted over next few weeks, so a little more power and torque than standard!!

sorry James but that's simply not true.

since when has 430hp been 'a little' more power Rolling with laughter

looking forward to the photos etc. Thumbs Up


..... next you'll be telling us the only reason for doing this is because of the issues with diesel exhaust fumes etc Laughing

Your upgrading the diffs to lsd rear and four pin front but not the shafts or CVs in order to keep a weak point is how iread that

Really.

I would upgrade them too, then at least you can drive it which I assume is why you are putting the engine in anyway?

We run a lm 5.3 around 400bhp with Nissan 9" diffs and longfield shafts. Shafts still break. Changing to spydertrax shafts and knuckles for this season still running 9" diff. Front with locker rear on spool. Cheers

@Caterham. - yes of course I am! Diesel is not the fuel of satan so I'm switching to petrol to be more eco friendly 😄

@JST - getting so much conflicting info here. Halfsahfts and flanges I'm planning on changing but not driveshafts. From speaking with other people who have upgraded, driveshafts haven't failed but half shafts and flanges have. 2 pin diffs have also failed as far as I can see but without definitive data how the hell do you know! If a drive shaft failed then I can at least engage diff lock and still get drive as a get me home.

So I still need to know the front diff - I'll call the dealer and ask them the build.

I'm of the opinion to just make everything as strong as possible so none of it breaks.

I just don't see the logic in making something weaker so it breaks!

The gearbox should be plenty strong enough, as it's basically the same one as used in the Mustang.

The weakest point is likely to be the clutch, they fall apart even with 120bhp.

there is aways a weak link somewhere. on my trayback its the LT230 which as we all know are quite strong. and thats not broken yet.

OK that makes sense so you are doing shafts and CVs just keeping the original props. i follow now. my understanding of driveshafts would be halfshafts. where as i now understand you mean driveshafts = Props.

Build sheet for mine says 4 pin front diff. it still had a 2pin in it. Cheers

LOL thats useful saying 4 pin and then finding its 2 pin!!

Yep thats where my head is just now, will run the car as is but carefully as I run the new engine in and then at 1000 miles when I have a service ill have the half shafts (props?) and flanges replaced with uprated ones.

Ill ask my mechanic to have a look at the front diff and will strengthen if is 2 Pin.. Then i can really open up the V8 Very Happy

I'm not sure the build sheets are always that accurate, mine says it has a "rear diff 2 pin", but as i understand it all 110's have a 4 pin rear as standard.

Perhaps this is due to the ambiguity of the technically meaningless term "2 pin" .

A diff can have either 2 or 4 differential side gears. If it has 2 gears, they are carried on a single cross pin. If it has four gears they are carried on 2 pins. So a four gear diff actually has 2 pins. No landrover diff on earth actually has four pins.

"Two gear" and "four gear" would be the correct terminology.

(Don't get me started on the term "hawse fairlead" either, because again there's no such thing! I blame the internet formthe uncontrolled spread of meaningless pseudotechnical babble).

Sadly forums are a double edged sword - lots of internet myths, that just perpetuate.

"cheese diff" Rolling with laughter
In my opinion you may put more torque (stress) on your drivetrain with 120hp and aggressive tires than with a v8 and road tires. I wouldn't change anything untill it fails. Cheers,

I am having a thought that "2 pin" may be a corruption of "2 pinion" and that is how it has started up. 1995 Defender 110 CSW
