Keep it Land Rover?

I bought a clean high miles D90 about a year ago with the thought of possibly doing a cummins 4bt swap down the road if it needs it or I decide this is a vehicle I want to keep for the long term. I'm always evaluating this... I have done 2 previous 4bt swaps and several other engine swaps and this would not be the most difficult of them (4bt, nv4500 and an atlas II would fit nicely). Maybe I'm getting turned off a little by the whole "keep it Land Rover" mentality that seems to prevail?? I admit, I don't know much about the LR motors but I do know the 4bt pretty well. Cost is always a consideration but not the only one. Just looking for some advice from the group here... 4bt v 300tdi??
many thanks,
-Jon

4bt would be better and cheaper. People are really growing up on the whole " keep it rover" thing. Besides, do what will make you happy. Axle upgrades will be a necessity if you plan on using the atlas.

Cheers

Isn't a new 4bt like 5500 or something?

The whole "keep it rover" thing has its place, and in many ways its fun to see what you can devise using stock parts, but there's got to be some tolerance for the custom route too. I personally can't stand SBC's, because people seem to want to shove them into every car I've ever owned, from BMW 6er's to Alfa Romeo's etc and it gets old watching the old debate start all over again about "ease of serviceability" and "cost of parts" and other such nonsense.

Go for the Cummins - some have done it and it seems to be a great motor for the D.

Do the cummins and keep it. If I plan on keeping a car/truck, I modify it into what I want.
Example, I took my original low milage '86 Buick Grand National and made it into a low 9 sec strip/street drag car. Purists cried... F'em, it's mine.

No comparing the power you would have in the 4bt compared to the 300tdi. I have had 3 300tdi and I think everyone of them was under powered. I don't want a speed demon, but I would like to be able to maintain the speed limit up and down in the mountains with a loaded truck. Instead with a 300tdi you are on the shoulder going 50mph, with the a/c off, if you turn the a/c on you might see 45mph. If I had the ability I would go with the 4bt. Just my 2 cents.

If I didn't have a 300tdi - I'd go Cummins 4bt. And if/when the 300tdi dies (hopefully after hundreds of thousands of miles), I would go 4bt.

No to hijack too much, but wasn't there a guy that put a 4bt into 90 recently and driving it around the US?

Yeah, Shane at Rover Hybrids did it... The guy was taking pics around the country. www.vanishingamerica.com

It was pretty interesting and it ran on Veggie oil too, so did his motor home.

The one they did at RoverHybrids is a beauty. I contacted them about a couple of diesel swaps options and the 4bt was $30k installed. Seemed a bit steep, but with the custom work and engines getting harder to find, it probably isn't too far off. There is a Land Cruiser shop (Proffitt's I think) that does 4bt swaps regularly...it's about $18k and you provide the Cruiser.

The first 4bt I did , in an early Bronco was about $2k for the motor, it was basically an unknown miles regasketed delivery truck takeout. The second was a similar beginning but a couple years later and about $2800 (went into a '57 willy's pickup I built for a guy, he sourced the motor). A cummins certified rebuilt motor is about $5k I think. They are fairly cheap to rebuild and parts, turbos, etc are readily available if you don't need/want the warranty.

I'm not about to pay someone else to do anything, not my style. I enjoy the build as much or more than the finished product. I think most would say my shop is a little ridiculous by most home shop standards but I will just say I have an amazing wife.

I think this seals the deal for me. I just want to be sure I'm not passing a real awesome motor because I don't know something about it.

If you are clever, you can get the engine fairly cheap. He got the engine in a old frito lay truck at an auction direct from frito lay for something like $2500. Pulled the engine and put and old small block in it and sold it for $1500, so essentially hes into the engine for $1k.

I saw that build on www.4btswaps.com. He's put a ton of work into it, and looks like a bit more to go. That is definitely YELLOW.

I have a friend putting one in a Scrambler right now, sourced from a bread van too. As far as "keeping it Rover", that attitude is for car collectors and snobs as far as I'm concerned. I wheel my truck, not enter it in car shows.

Here is a pic in the Scrambler.

What's the saying? Oh yeah:

"This thread is useless without pics (of that low 9 second time slip...)"
