Anyone put anything lively in a RRC ?

The handling must have been ..... Interesting !!!

Think I have decided on an ACR 4.8i, gas flowed heads / BIg valve with a new Ecu.

And to keep the original matching number engine to one side once rebuilt.

Need to find someone to fit in the Berkshire area who I trust ! Had so many bad experiences !!

( I do however reserve the right to change my mind !!)

Might be too far away but try these guys. http://www.lloydspecialistdevelopments.co.uk A mate of mine had his Chimera fettled by them last year and was very happy.

A bloke in the US put the Humvee engine in a P38, even sells a kit to do it.

I've got a Range Rover CSK that had a 300BHP 4.6 in it, just taken stage 3 heads off it and gone back to standard heads/injection in preparation of selling it, left the 4.6 and camshaft in there though. Handling was taken care of with lowering springs, bilstien dampers, poly bushes and 18" wheels (same as sold by twisted for their defenders). Went pretty well.

I'm about to put another 4.6 into a 4 door classic with the stage 3 heads and a torque bias cam, should be quite nice for towing

Interesting, which engines are they i.e. RPI, Turners ?

Were they reliable ?

Have seen your CSK its absolutely lovely, needed some work though !!

Sorry for all the questions I may have more !!!

Thanks

The block in the CSK is just a standard 4.6 that had liners and cam bearings done by V8 Developments which I then built up myself. The new one is from V8 Developments and will come as a short engine, the heads also came from V8 Developments.

Engine/heads/cam in the CSK have been fine, done quite a few miles and took me to the south of Romania and back in some crazy heat.

Thanks, building the CSK was fun, I've decided to sell it now though

[phib]

Perfect thanks for the info.

You don't want to take a 60k mile, 2 owner, 91 Vogue SE in part ex for the CSK ? No Mot advisories but will need new head gaskets or engine !!!

Had £4.5k spent on it recently :-) but always love your CSK !!

That looks lovely, if I didn't already have my 4 door I would consider it, trying to thin the fleet down a little though

Ok. Having spent about four years faffing about deciding the engine route for my two door project I can mKe the following observations:

Sticking with an RV8 is the easiest option for obvious reasons. Personally, I wouldn't bother much above 4.6 as the more the increase the cc the more long term hassle you're buying. Sure, people have got North of 300bhp from them but it's bloody expensive and they tend to be much more fragile.

In addition to this, above 300ftlbs and the R380 manual trans, the 4HP22 auto and the later borg Warner transfer case become consumables so really need replacing with their uprated versions from Ashcroft.

The Chevy SBC and also LS series all fit and fitting kits are available. They deliver the power of a hugely tuned RV8 without breaking a sweat.

The Jag AJV8 can be fitted but you need to start cutting the bulkhead, buggering around with the sump and also fabricating bespoke adaptors. Even then, like the Aston V12, it sits further forward than you want and upsets what is actually an exceedingly well balanced car.

The final option and the one that I am going to install is the M113 Merc V8. Superb engines, smaller than the RV8, very tough and in 5.0 form delivers a very easy 350 bhp and also ftlbs. It also has the torque where you want it for the ZF4 auto.

I toyed with using the Amg version but it really is too much power and means toughening up all the rest of the drivetrain as well as needing a proper brake package.

I'm already using a Disco 1 front axLe so that I can run Dedender 110 brakes at the front. That's the best solution for increasing stopping power while still being able to retain 16" wheels. Although a later, metric Classic can fit those brakes straight off as far as I'm aware.

Be interesting to see that as 'how to' with lots of photos.

I could do with that also.

I'm using a non electronic HP box with uprated internals. I was going to use a TKO manual as modified by Rakeway but I suddenly realised that I needed at least one auto car and that the Rangie is about wafting and was always better suited to being an auto anyway. So that means the most complex element is going to be the manufacture of the adaptor plate from that to the engine and how to handle the differing spline output/input. Once that is negotiated then mounting brackets and the ECU should be more straight forward.

I'm hoping to start work over winter on this aspect.

Have been speaking to Lloyd developments, they seem very knowledgeable and they use ACR ( which was my preference)

I am not that mechanically minded / have no time so having someone who can sort the whole thing would be great

I approached them a couple of years ago when I was looking into installing an AJV8 into the two door. Nice guys and their well laid out and thought out quotation suggested to me that they knew what they were doing.

Wasn't there a firm in Melton Mowbray called TMS. They did Litchfield badged Range Rovers with TVR engines in them. I guess they are no more.

Do any of these survive?

Yes. Dom built the engines. I've seen a couple over the years. If I recall they had a shade under 300bhp and went rather well.

It's the easiest type of conversion as in simplest terms it's a straight engine swap.

Downside these days is that a new RV8 built to those specs is over £10k whereas an LS is half that and just a much better engine.

TMS Land Rover were bought out Marshall Motor Group. There was also TMS TVR so the connection makes sense.

Yes. They sold a Rangie they called TMS but then Lichfield gave them the right to use his name. I think it was by then that they were a TVR dealer.

Another vote for Daniel and Nathan at Lloyd's. Mine spent about 4 months there last year and its due back for a few bits next month.

I have a nice 4.8 cross bolted V8D engine in my RRC, goes very well and surprises a lot of people when I bury the right foot

[WTFWT]

i was in the same position as yourself and pondered and researched all the options for my 50th Defender.

In the end I went for a V8 Developments 4.8 aiming for 300 hp. I drove the car up and dropped it off with them and picked it up a few months later. It's sweet. Fast, revs very smoothly and sounds great. It is thirsty though and it took further to tweaking of the mapping to get it just right. Ray builds a good engine.

[vjj]

Had a long read through this

Some comments

Stage 3 heads and torque cams work against each other - torque cams run out of puff at 4750 just when the benefits of the head work begin to show

Stick to stage 2 with medium valves

I had V8 developments build an ultimate 5.4 last year to go in a German 2 door RR with a 5-speed manual

Dyno'd at 346bhp at 5400rpm
And 385lbs at 3800 running an edelbrock 600
£11500 plus vat

Big rover power costs money - a chevy zz4 crate motor makes more than that - especially the torque - and costs £4700 including vat

Do the maths.

My own 6.3 litre 90 has a vacuum ZF auto from ashcroft with the later internals and big planetary gears - I also adapted a massive Hewland torque converter to fit -15000 miles and no issues - twin oil coolers are the secret

Desolate's 6.3 classic has a TH700 4-speed chevy gearbox and Ferguson Formula transfer box - same as interceptor ff ☺

His 90 has a John Eales 4.9 - now he calls them 5.0 - running hot wire and a Kent 218 cam
It is lovely and would be perfect in a RRC

Not cheap though at 10k!!!!

Donkey - that merc engine is a good idea - but there will be a lot of aggro

I am rebuilding a TVR 5-litre at the moment with
Stage 1 heads and a kent H180 torque cam and edelbrock intake and carbon

Will be about 260 bhp and 300 lbs torque

Drop me a pm if you are interested
