Factory lpg owners

Robson Rover Repair · 22nd May 2021, 16:43

Folks, I hope people could help me.

I'm on look out for a factory lpg kit for a kv6, however as part of that I'm hoping people could maybe shoe me their factory lpg kits and aftermarket installs.

It would strictly be a spare wheel setup not a large boot tank.

Also I'm keen to hear mpg, anyone who's used conversions or done a DIY.

Part of my v6 rebuild may do it all at once.

I’ve got the original MGR lpg course notes somewhere..... I’m fairly certain it was only a factory option on the 1800 though

Could swear I was looking at a factory fit 2.5 a couple of years ago on eBay - I only remember as I would have loved to buy it. It did say it was extremely rear mind.

I've considered buying a V6 and putting a system in myself as I'd love a 75 with a true Rover engine. I had an old Jeep Cherokee with LPG and did a few repairs on it a while back - they don't seem all that complicated but getting your work signed off does if you're fitting a new system yourself. The other thing to consider is that LPG is about half the price of petrol but only gives two thirds the efficiency with the older, more affordable kits. When I worked out how long it would take to cover the cost of the kit it hardly seemed worth it.

Mate Mark has a v8 he's gonna be rebuilding I think factory lpg also, was the famous one someone stripped and left as a mess.

When I did the model launch course in around 2003 I think I’m certain it was 1800 only, that may of changed afterwards? Although a ‘factory’ option they were converted after the car was built iirc but sold as an option as it was converted within Longbridge. Any cars converted after purchase would potentially look similar as a well known kit was used by Longbridge. They were an incredibly rare item and the dealer I worked at only ever sold one. There’s mention of lpg on one of the service sheets I think as the plugs were changed at different intervals.
I could be wrong of course as it was a long time ago....

I'm also pretty sure I've read before that "factory" lpg conversions were only offered on the K series engines and not the KV6. I bought my ZT V6 180 auto with a BRC kit already installed which initially worked well, although it's non-operational at the moment. I'm planning on re-commissioning it soon. It's correct that the efficiency of lpg is less than petrol and hence the mpg is less. I get a fairly steady 29 mpg on petrol overall (with no particular concession to an economical driving style) and when it was working I calculated that on lpg it was 24 mpg. However, the half price of lpg does definitely make it worth having and I reckoned that the overall fuel cost of running the car on lpg was pretty much equivalent to the cost running a diesel engine.
I have a 60 litre "toroidal" lpg tank in the spare wheel well. The boot is big enough to make carrying the spare wheel loose not too inconvenient most of the time.
