please comment if you have real input :)

I have a plan to build the best possible Range rover classic from the best parts from the whole range rover series.
they alle had their god and bad tings. and i love the look of the Classic, but would like it to be a daily driver.
with mostly on road drive , with some horse trailer driving , and 2 yearly trips thru europe.
would like it to be updated with climate control with vents to back seats. heated seats front and back...

what should i get from what ?

I was thinking:
-Engine and transmission : m57 + 6hp28x ( strong and plentiful )
-keep the RRC axles ( not much difference to the P38 )
-L320/322 complete wiring (except for engine )
-L320/322 interior and dashboard
-L320/322 ABS and air suspension control ( will work better than RRC and P38 systems )
-Transferbox i am not sure if keeping the original Borg and warner or change to a new one that works with the computers inside.

I am fully aware of the complicity of the project, but the RRC will be supplying frame axels and body.
another RR will supply wiring ,and interior .,,,
and a BMW engine will be the last part in this ,but as it is all Canbus it should be possible to get the systems to talk together.
and in worst case the engine will work as standalone.

suggestions for better part compatibility and ease of installation , or other suggestions

thank you , i have been lurking here for a while with out creating a profile, i am close to ending my CJ7 Jeep project so i have been looking into a RRC project , think I was in one 40 or 45 years ago .. and loved the combination og style and proper 4x4 ability

It’s a start. A proper one.

What size wheels/tyres will you have on it?
Click to expand...
tire size is always difficult, because of suspension height is influencing it a lot. i would like to go maybe 18 or 19" for sure not going for 22" to not enough tire to drive comfortable.
but pretty sure it will be beluga black with , alurims and brown / cinnamon seats. i was close to buying one with that color combo, but it was so rusty , that i would have spent a lot on rust repairs before the rebuild could begin.
 
Have a look at the ZF8HP transmissions. They are a decent step up from the 6HP.
Im in the planning phase of changing my P38s 4HP to an 8HP a really cool part about this is the 4HP has a 2.7:1 1st gear the 8HP ive gotten has a 5.5:1 1st. So crawl speed is going to be insanely slow. The breaking of CVs will probably be way easier:rolleyes:

Id try to fit the whole driveline(engine + transmission + transfere case) from some newer model car. Itll just make packaging and electronics easier. Have a look at like BMW X5 drivelines. You just going to lose low range on the transfere case. The X-drive stuff is quite impressive though so if you not going to be doing rock crawling the i dont think loosing low range is such a big deal.

Are you actually for real? Are you doing the work yourself (I'm doubting, as you simply wouldn't ask some of these questions if you were). What is your budget? £20k, £50k, £150k or more?

Doing this will likely result in a non roadworthy vehicle in the UK and would need to go for an IVA.

It also sounds like the entire project would be pointless, as you'd end up not having the character and charm of a classic anyhow.

I think the ZF8 is actually in RRS the last years 2011 off the TDv8 i think, but i am not sure if the bell housing fits the M57 Engine. my plan was also to use the complete driveline except the transfer case from the RRS should fit 6/8HP transmissions

My plan it to do a restoMOD , and i think there this looks quite nice : crown rr
I know that one is a RRS with classic panels on top. but still looks nice.

I am doing the work my self , i have just finished a jeep , not as complicated , but lots of Fabbing and electrical investigate and do . really fun and interesting.

regarding the roadworthyness, a classic has frame and body construction ,here In Denmark you are allowed to do changes as long they are approved by a engineer . changing axles P38 would not needthat ,but just a MOT to see that it i installed correct. and most of the changes in my project would just be informing MOT of the Changes.

but if i changed the suspension to multilink or similar things then THEN i would have to do the engineer control.
 
I confess to not being an engineer, but don't have to look far to find a level of irony in your plan.

As I understand it you want to take the best Range Rover model the old Rover Co (latterly LandRover) ever made, renown for it's ability, reliability & mechanical simplicity .. then throw in the totally unreliable crap JLR have been incorporating into their models for decades.

I can fully understand JLR designing products for a changing market, where poseurs have largely replaced 4x4 enthusiasts, but to contemplate morphing a Classic into one of these ghastly JLR offerings in an attempt to produce 'the best possible RRC' o_O

Am I missing something here?

I had a RRC it would be better to spend the money on re-building as standard best and most reliable vehicle I have ever had appart from a bit of roll at speed round corners

Lucky there, my '87 Vogue had LR developed anti-roll bars retro-fitted by one of it's two previous owners, sacrificing (allegedly) only half-an-inch of suspension travel, for those few owners that would have actually ventured off-road ;)

Yeah i think the TDV8 had the 8HP.

This is what i would do
B57 engine along with its 8HP transmission out of a G05 BMW X5 and all its electronics that go with it, mainly the ECU.
Design an adaptor plate to fit the borg warner transfercase to the 8HP.

I would try to stay away from newer Range Rover parts, they not nearly as common as BMW stuff and they have a decent price tag attached because they came out of a Range Rover.

As youve probably noticed you wont get very many positive resonse from this forum.

I know this is not a idea that all will like and approve of. 🤣

as I wrote i would like use the best parts from the land rover parts line.
If all the parts on newer range rovers / land rovers are crap. then the project has no purpose.
but i am pretty sure , that there are things there are better on the newer models.

-P38 axles compared to RRC ... a bit stronger 👍 .
-fuel economy on a old V8 or reliability on the VM diesel, can be better .
-Brake system , there must be parts that could make a old RRC brake even better .
-transfer case : borg warner, Lt230 , newer models ?? maybe with terrain responce ?
- Airsuspension is the old RRC/p38 system better than the newer ones ?

is there something to gain ? or is some of the original parts the best ? the idea was to take the best
as see if you can build the best / most reliable RRC

i will be a hell of a lot of work , but that is the fun part of it. the RRC needs a full rebuild , so it is not a one of a kind, or close to original. so there is not a loss in using it for a project like this.

The BMW G05 is a very expensive setup. but agreed a VERY nice setup 👍
The M57 can be setup with the 8HP with a cantu box and will be a reliable setup at a much lower price
and there is support available to assist with programming and fault finding.
 
Put the rrc body onto an 80's G wagon chassis and running gear with the 6cyl mercs diesel engine and gain the hydraulic diff lockers as well. That thing would crawl up the side of a house if it could 🫵😎
 
Youll have to stick with the Borg warner transferecase because of the left hand drop propshafts. The LT230 is right hand drop.

If you going to take P38 axels use the P38 air suspension too, the P38 air suspension is set up for solid axels while the newer airbags from independent suspension range rovers wont give enough travel. The P38 air suspension works very well if you just replace the o-rings when they leak and ensure the height sensors are in good condition.

Then if you using P38 axels why not just the whole braking system too?
