Diesel options for '87 RRC

I have a friend here in CT who has a 1987 RRC with the original 3.5L motor. I think he has owned it for 20 years and the motor is getting tired.

We have talked about putting a diesel in it. He wants to stay with an automatic. He is the type of guy that would want to do it himself, he has a nice garage with a lift, etc. I know 2 of his best options are 300TDI and PS2.8.

Beyond that, I am out of my comfort zone...

Pendy has told me that has parts available to "convert the transmission" (the ZF in the RRC) to work with a 300TDI. Is that needed for a PS2.8 also?

From reading the 2.8 thread, it sounded like David Shechter's truck had a ZF but it wasn't clear if it was converted. Then the '97 D90 version (ZF 4HP22) was rebuilt to P38 (ZF 4HP24) specs.

I know the MDE kits come with some things like motor mounts and adapter plates...

But I don't think my friends wants to spend MDE-type money.

I know some people have bought from Duncan from landroverimports even though Pendy was not pleased with the boat anchor motor. He also is selling a 2.8 kit. Has anyone bought one of those from him? His ad says it will bolt right up to a ZF.

At this point, I just need some advice about whether 3-hundy or 2.8 is better.

many things will bolt together. not all will work together.

I would suggest your friend try driving some Range Rover diesels before commiting. I have both standard and automatic versions at the shop.

I do not currently have a 2.8 here. I will not offer those with autoboxes any more after having done a couple, unless someone has deep pockets and a good sense of humor. 2.8's also require additional expensive cooling equipment, especially if run with an autobox.

http://www.erikssonindustries.com/ will rebuild ZF to diesel spec. You can buy a used box with your motor in the UK for less.

Rebuild it or put in a 4.6 block. The 4.6 will really wake up that tired old RRC. I can't imagine that a 23 year old RR is worth putting any money into unless it is really clean otherwise. If he really loves it that's something else. I say drive it until it falls apart.

Are you talking about the 2.8 he has on ebay?

FYI that is a Isuzu motor not the 2.8 PS motor

Thanks Dave. I saw the displacement and assumed it was the PS motor.



Anybody: what does my friend need to mount a 300tdi in his '87? Are the motor mounts different? Assuming he has the parts from Pendy to convert his ZF, what else would he need for the 300tdi?

earplugs

I think that a different fuel pump is needed as well as filters. Not sure about motor mounts, he may need different ones welded in. I may be wrong, but I also think he'll need a Tdi radiator with the integral intercooler. Also, consideration for air conditioning and heat. There's probably a 300Tdi a/c compressor mount somewhere out there. That will mean cracking open the a/c system and rerouting all the stuff. Plus a recharge of course.

Just my opinion, but I think a 300Tdi in a RRC will be a dog. If he's OK with that, full speed ahead I say. Whudda I know?

my Defender 200tdi was originally in a RRC in the UK. I know when I ordered it he took the auto tranny off and gave me a lt77. I'm not sure what tranny it was, but I got it from Leachy who use to be on the board.

I also think you need a different torque converter and flexplate.

I'd also consider changing out the Borg Warner for an R380 and get the lower gears in it.

UH, I mean LT230 transfer case

It's a 1987 so it has the LT230 [BW started in the RRC in '89, I think].
