Iam looking at possibly doing an engine swap, but looking for other ideas than Rover engines.


Do you intend to keep that truck road legal? Perhaps you need to contact your Kali DMV to understand what happens when you disable the OBD II system. I hate to break it to you but you need to buy a DI.

Has anybody thought of a BMW straight 6 M50 M52 S50 or S52 engines? They don't need much connected to the Rover to run as long as you got the original engine harness and the ECU. BMW also has a bell housing for 4HP22.

Nice engine but also prone to cracking cylinder heads. Plus those engines don't have much lower end power. Better engine would be a E39 E38 4.4ltr V-8. Problem with the OBD2 4.4 is the immobilizer spyder ECU. You could use a OBD1 ECU but that would never work if you had to smog your BMW powered Rover. Very cool motor and also aluminum and sounds like an F1 engine when you full throttle it. Also mates to a ZF transmission. So a bell housing swap may be possible. You can get 20 mpg with that engine and a 740 is almost 3 tons

MB engines were mated to MB transmissions. The BMW and Volvo engines were mated to the ZF transmission.
that appears true for NAS MB cars (MB uses ZF 4HP2x transmissions elsewhere).
Whoever wants to put a BMW straight six in their rover - measure the BMW's engine length, and that of your hood.

I'm learning to really, really like the 4.4!

There are some things that don't make sense, but they are some SMOOTH engines!

I would like to know why it so difficult to remove the fan clutches from them.

You can get a used 2.8 M52 for as low as $600 with wiring and ECU. Power would be about the same but you can supercharge the BMW engine for about $4K and get 350hp out of it reliably.

BMW parts are cheaper than Rover in most cases by the way.
Speaking of cheap parts...
It's a violation of federal law to use an engine older than the vehicle (not that I particularly care about it, but the OP lives in California with his 2004 MY vehicle).
I kind of doubt that one could get any 2004 and later engine - including mopeds and snowmobiles - with wiring and ECU for $600...

Yeah, you don't swap in a non-Rover engine to save money. Unless you own a scrap yard and a machine shop.

...and don't waste your time with a MB engine either. My Dad's had 2...a GL320 TD and a new GL350 (?)...both have broken down and left him stranded a couple times each. I don't know the specifics of the failures, but I know they were mechanical problems with the engines. (Dad lives 1500 miles away and now just swears a lot when I ask how is MB is running.)

Hey PT, BTW...If/when mine fails (assuming it isn't junk already), I may be shipping the whole truck to you to put a new motor in...or maybe we can explore finding a TD5, ecu, and manual transmission for it. (Ahhh! It's nice to dream...)

I have a D1 with 300,000kilometres on her and going strong. I have a D2 with 165,000k on her and going strong (albeit with a vacuum leak that I cant find!!). For my money if you want a usable addition to the 4.0 (or 4.6 minus the first part) you stroke to 4.6 and use top hatted liners to prevent sleeve movement; porting and polishing of the heads, port matching of manifolds, full balance (including balancing the harmonic balancer itself); mild billeted cam. Lets face it this motor is going to give you some very usable gains and mild cam will not upset her offroad idling around.

Cheers

Rather than change out the engine, why doesn't someone come up with a mod to the center diff that will allow for 2H. Getting out of 4H all the time outght to buy you 3-4 mpg for a lot less money, and improve acceleration.

Thanks for the heads up to this site. This part
http://www.toddcosuspensions.com/lt230pati2wd.html is exactly what I was talking about. I just need to confirm with them that it doesn't eliminate 4H leaving you with 2H and 4L. I want all three options.

Vanagon syncro freaks sell a kit to change to rear drive only. The advantage is the driveline never articulates in a Vanagon. Where a Rover front driveline moves alot.

I believe it replaces the center diff with a spool. So you lose your AWD (non-locked 4), and can only be in 2wd, or locked 4wd.

I really don't see why there would be any MPG gains. All the front rotating drivetrain will still be rotating. Unless you somehow unlocked the hubs, the tires will turn the CV's, which will turn the axles, differential, which then causes the front driveshaft to turn. Everything is still turning, you have all that rotating mass and friction, without the benefit of AWD.

R - you should know better that loaded gears (ring and pinion, and the diff itself) use more power than simply spinning ones.

That said, there will be little to no power/gas mileage gains with 2HI conversion, but the handling may get worse.
