I love it when a plan comes together!

Sorry, this was a bit harsh. I must have been having a bad day.

It is a cool project and I too hope to see it finished, hopefully you aren't too stubborn to go back and re-engineer any misguided decisions should they arise.

Has anybody ever re-tuned one of these engines for low end torque? I'm curious how much you can mess with the cam timing to boost the bottom end.

I was wondering what high range ratio they used in the South African edition. And whether or not the ZF box could be connected to it with the bell housing from the RR 2.5 diesel. Think that was the only other RR with a BMW six

It gets about 275nm of torque at 1500rpm.... That's not bad... You want more?

Hmm, good question about the ratio. I read the R380 in the 2.8i is same as the 300tdi other than the input shaft, but who really knows. I'm sure you could use any BMW 4HP22 ZF bell housing.

You're right... Rover v8 puts out 285 or so... But it has better fuel economy... Which is something I worry about on longer trails.... Maybe it's my gearing but I have never had a problem with power getting up a hill... Plus it's Beemer engine

Any 4hp22 housing will work. That's how mine is. In fact, it has a BH from a M20 powered car. M20, M5x engine all share the same BH pattern on the block.

I'd be interested to know what they used in the SA trucks. Seems to be almost no info out there on them. Mine is just running the 4hp with a LT230 28D from a 96 Disco 1.

What would you like to know about the SA trucks? I know most things about them now.

Andrew, have been following your build in this thread...
NICE WORK !!!

Engine conversions are never based solely on skills, experience, or knowledge which can be learned along the way.
What gets you through a conversion is the perseverance to tackle one issue at a time and a willingness to invest the resources (in this case money and time) to bring the whole project to a successful conclusion.


Question:
Have been using a Chrysler air cleaner for my Mercedes conversions, but they are getting hard to find.
Could you please post or PM me the rough dimensions for the air cleaner you are using and what mounting brackets you used?

NO.

The 4hp22 was used in many applications, so the Rover 4hp22 can have the bell housing swapped to accommodate a BMW I6, Jag engines, etc, etc.

LT230 may be able to bolt onto any 4hp22, but I'd think you would have to swap the rear of the 4hp for a Rover 4hp rear.

Andrew:
A guy down in TX with LHD and AC installed an OM617 in his 90.
He relocated the alternator because he didn't use the factory one.
This required him to use a different AC compressor with LHD.
To make it all fit, he ended up using a P38 steering box and overcame all the panhard rod issues.
If you decide to go with the P38 Box, PM me and I'll put you in touch with him.
He will be able to walk you through how to accomplish a successfully install of the P38 steering.

I'm def interested in the P38 dealio. Would help a ton as I have my alternator up high and no PS pump.

Change the bell housing. The 4hp22 is in every RRC, Disco 1, and 97 NAS 90's. These trans were used in everything from 3 series bmw's to the 7 series and big jags. One of the most popular transmissions of the 80-90's

Yeah, I surprised I could get it for less from John Deere than from a Donaldson distributor. I ordered it from www.greenfarmparts.com. It came out to $132.79 after a 2% off promo code plus free shipping.
was going to say that looks like the Wolf military donaldson assembly that is an upgrade for a 300tdi (flows better).

Hey thanks! I agree! The dimensions for the air cleaner can be found on page 3 of the FPG RadialSeal technical data sheet:http://www.emea.donaldson.com/en/com...ary/049945.pdf They come in a variety of sizes. The Defender 2.8i version is model # G070009.

Thought I would join up and say hi considering I have just fitted a M52 to my defender, found your thread after searching for bits and pieces for mine on google!

Mine is on the road now and it is fantastic, being that the M54 is better you won't be disapointed!

For interest I went down the R380 / LT230 route, if you want any info I have a build thread over on LR4x4 http://forums.lr4x4.com/index.php?showtopic=76920&hl=




It's more or less as you see in this photo, but finished off (rad mounts, enclosed air filter, brackets etc). Keep meaning to take a new picture!

Adam
