200tdi Alternator Upgrade Options?

I have a LHD Defender 200tdi. I have searched the forums extensively and have not found a definitive answer to what fits.. I am in the process of wrapping up a chassis swap and still have the wings off which would make replacement simple. Alternator is currently working fine but I will be adding some electronics and would like to upgrade from the stock 45A. I think an 65-80A would be sufficient for my needs down the road. Which alternator(s) will fit in the stock location with minimal modifications? I already know the harness will need to be upgraded as well.

Thanks
Ryan

Do you have AC?
I have a 200 amp conversion that fits the disco 200TDI engine.

There is a 65 Amp alternator that is stock and fits directly in. That is the simplest solution. Other choices are difficult with a LHD.

Do you have a part number? Is it a land rover alt or something else over the counter?

Same alternator as on a massey ferguson tractor.. Look on eBay.. I put one on mine and it works great.. Mine is RHD but I don't think it makes a difference.. Biiiig amps are over rated... You don't need anything more than 80 at the most...

Britpart is doing a 120 A direct fit unit now. I've had one for the last year. Seems decent. Around $200.

I bought a 90amp from a Range Rover Classic from O'Reilly's Automotive it was a straight bolt up. I drive LH drive 110 with a 19j.I believe that engine and the 200TDI share the same alternator mount. It comes with a lifetime warranty. What's nice about this alternator it has the tach. terminal

The mounts are the same but you need to be careful with clearance to the intercooler pipes. It is all very tight in that area on a 200tdi.

Very true I forgot about the intercooler pipes on the 200 TDI. I do run an intercooler on my 19j but the routing is different. I believe I'd do some measuring of alternator diameters to see what you have to play with for room.

To bring this back from the depths. I did not end up replacing it until last summer but I went with the Britpart DA1195. Which is a 100a alt. The regulator failed on my previous alt and seems to be the case here again in just about 5k miles on the new unit. Don't think I am causing any issues but wondering what may be causing these failures. Anybody else running this alternator have any issues?

I was concerned about fit after having read some threads on the issue but had no trouble installing the 100 amp kit (britpart DA1195). My 200TDi does have power steering, and still no issues.

I made this setup to install an AC compressor and a 200 Amp alternator on a 200TDI disco engine.

No problems here. Maybe there is something causing it on your truck or it is just a weird coincidence. If the warranty replacement fails again, I would start to believe it is the truck.

Yea I'll find it. Fits in the stock location on defender engines.


Edit: not as massive as I remember but 75amps is better than 65 I guess lol.

It's a Massey Ferguson mf-4225 alternator aka 12088n alternator.

Even uses the stock wiring plugs

That is the normal stock 65 A alternator. Yes, they are fairly common and easy to source cheap. They are calling it 75 A, bit it is the exact same alternator referred to as 65 A that is a stock unit.
