Turbo on Disco 1 V8 Petrol
Hey all,
It has been suggested to me by a mechanic friend to put a small turbo on my V.8 Petrol1999 Disco 1 (good condition / 148,000 km). I 4WD a fair amount, rock climbing and similar, and the additional power would be handy. I have approximately 50mm lift with 265/70 R16 rubbers, fairly standard build. They said it was increase power and was likely to improve fuel consumption.
A few questions...
1. Is this true?
2. If possible, would it be advisable? I am thinking that it may result in extra strain on transfer case and auto gearbox.
Many thanks for you replies.

None of this. Lol
A few have tried. These engines are a bit....fragile as it is. A turbo would only exacerbate it's weaknesses.
A turbo in general is a hindrance until it spools up enough to make power. Reving at that required RPM while trying to negotiate an obstacle. Unless you're going through level mud I guess

I had thought of this as turbos are in my bloodline, it wouldn't necessarily be a bad thing if the turbo is small enough. You wouldn't really lose any bottom end if you trade off for high rpm pull. Something easy to spool like a 16g if you are doing it on the cheap would work, just remember that a smaller turbo, though it would spool nicely and give better low rpm grunt, will also put more wear on the motor than a larger slower spooling turbo, thus negating some of the benefit. If you wanted to keep it simple, a "remote" or rear mount setup could be tucked up back where the exhaust is if a scavenger pump is used for oil flow (Google sts turbos)
Your Achilles heel would be the added strain to the head gasket, so I would definitely make sure I have fresh mls gaskets and arp head studs if even attempting this

I wonder if anyone has fitted a turbo can provide feedback for the performance afterwards, especially strain on the drive line and the fuel economy.
Also, while stationary, there is a significant clonking sound while moving from neutral to drive and back. This I think must signify wear in the drive-line, which will only be exacerbated when adding a turbo of any kind.

You'd be hard pressed to find anyone who's installed a turbo on this forum or any Land Rover forum. They don't play nice with the antique V8 engines. You'd be hard pressed to find anyone who's done it on an engine builder site as well.
If you want more low down grunt you'll have to do it the bolt on way with gears and the old fashioned way as in larger valves, injectors, port matching, mod'ing the trumpets and plenum, shaving the heads further, overbore to max and grab the 4.6 crank and find lighter rods and aftermarket pistons and headers. Then you'll have to toss the ECU for squirting/timing and make your own maps.
As far as driveline components handling more torque and power that isn't an issue, they're more than happy to accommodate a GM 327/350 without breakage.
Good luck on your hunt. Anything is possible, the only limit is your bank account.......

If going with either type of forced induction turbo/Supercharger I would look into a aftermarket FI set up.
There were early attempts at superchargers on these from some well known folks and fueling was always the short coming. Some added an extra injector to keep it from going lean as the factory system couldn't keep up with the added flow.
If you take care of that part reasonable amounts of boost can be handled with little issue.
You would of course want to address the exhaust and heads for improved flow to see more in the way of gains. Also probably a bump up on the camshaft as well.

If you want to run low boost without any ECU tuning, you can do a blow through MAF and a rising rate fuel pressure regulator.... For safety sake I'd probably add a water/meth kit as the ECU is going to try to lean out the mixture unless you're flooring it. The proper way would to be use an aftermarket ECU.
In my experience though, adding turbo's to vehicles that didn't come with them from the factory is a game left for those that really know what they are doing and are willing to deal with blown headgaskets and cracked ringlands.
