Shopping Diesel

I've got a 1995 Classic 3.9 which is running on its last leg, so recently, I have been doing as much research as I can on what diesel conversions are possible. I don't want to do a rover diesel due to availability and lack of power. I want to go with an American diesel because of the power. So lets say that I match a 6.5 Chevy turbodiesel with a Chevy transmission. Would the LT230 transfer case be able to deal with this kind of power? What other issues might come from this conversion?

You don't have an LT230 unless you swapped it in for the borg warner in your 1995 classic. Either will handle a 6.5 chevy, but the LT230 is better.

The 6.5 chevy conversions I have seen don't look too good. I would go with a 300Tdi.

The transfer case is fine. The axles will need proper upgrades or they will go boom. Everything else is like any engine swap...

- engine mounts
- tunnel clearance.
- engine clearance to everything.
- proper cooling system
- front suspension to take the extra weight

It is an involved job. Easy enough for some, a lot of work for others.

yeah, pendy put a LT230 in my classic when my u-joint blew and took out my tranny. I have seen one on youtube with a yellow defender and it seemed really good. I know putting a rover diesel in my rover would make sense but I just don't like how small they are and how they have no get up and go. my 3.9 is already slow enough with 35's. I don't want a speed demon but I don't want something that's gonna get really frustrating when someone on a bicycle passes me. i've just heard the 300tdi's are real slow.
here's the link for the defender i saw witht the 6.5

I was just talking to a guy at work this morning who has a 1987 RRC with LT230 and the original 3.5L motor. He was talking about possibly looking into a diesel. I suggested 300tdi or PS2.8.

Why don't you just Pendy?

I'm sure you will get some good info that way.

If you know and are local to Pendy, go see Pendy and get off the internet.... Go drive a 300TDI that he has tuned first. It should be much quicker than your tired V8.

Nothing wrong with the 6.5 conversion. But it is a lot more work and money in the end.

Pendy is 150 miles away from me. so it's not that often I get a chance to go down there. it costs like 100 bucks two ways to go down there in my rover. I'll PM him and try to find a friend with a fuel efficient car to go down there.

I like my 300Tdi, but if I were looking, I think I'd look real hard at 4bt.

My vote would be 4bt as well. Find the delivery truck, rebuild it, bam. Parts availability and a no-brainer.

I don't think a Tdi has no get up and go.
I mean I don't feel any difference with the 3.9 on the 90 ( and the 110 is heavier )

I've been googling 4bt since Chaucer mentioned it. Seems to be a very popular diesel conversion for jeeps and many other off-roaders. i'll ask pendy about those too. he has a cummins diesel dodge ram he's towed my rover on many times. Hopefully I can test drive a 300tdi soon and stop relying on what i've heard and go on what i've experienced.

Dude, you want a diesel swap and you're worried about $200? The costs will be neverending with that. Not speaking from experience, but why not just do a 4.6 swap. That youtube video was LOUD. I know my wife would sure as shit not ride in that thing

Chris,
Last I heard, Kermit here in KC still had a Classic with a 300TDI. You could also check with Kyle Caskey for more local intel on rover diesel swaps.

would you spend 100 bucks to test drive a car? i wouldn't and thats why i wouldn't drive down to pendy in my rover just to test drive a land rover diesel.

I'm not sure what the fascination with the 4bt is. Probably if you like a really loud, slow revving motor that will vibrate the snot out of everything......kind of like a 2.5na with sac. Don't expect the conversion or the resulting upgrades to be cheap.
A properly tuned 300 fast enough for normal people. I drive one or another every day and can't remember ever having difficulty keeping up or passing that which I wanted to. Plus I can afford to drive the damn thing. Co$t of the motor etc has come down allot also

i talked to Pendy and he said that with the size tires i'm running (35's) that the 300tdi really wouldn't be that great for me. he said my best bet was a 4.0 or 4.6 would be good or to just wait a bit till he has a mercedes 5 cylinder diesel conversion set up.

Pendy as always has a point.

However...as usual I can only partially agree. I run 35's or 37's on Stazworks beadlocks which are fawkin heavy. The rangie weighs 5200 lbs with me and all its junk in the trunk. 4:10 gears and 1:4 T-case, bigger intercooler, some good tuning and the thing goes fine, and will return mileage in the low 20's. It can be a little slow when driving in mountainous country but still keeps up with the crowd.

I'd suppose that everyones version of what "goes fine" is, and I am sure that the Pendy has a good finger on your pulse.

oh, and I did also convert to a 5spd which make the biggest difference. I have a '95 w/ an auto box 300 which is much slower.
