More torque in LD28
Hi there, I from Iceland and I'm new on the board.
I got a LD28 in my '85 Range Rover. the engine came out of '83 Laurel.
She's working fine but, lacks a little bot of torque on hi speed. She having a hard time to push the car on 38" tires.
my question is, how can I tune op the engine without damage her lifetime?
I rather not go with turbo mod.
BTW the engine only got 150.000 KM on it. so almost brand new.

Welcome to the Nissan Diesel board!
38" tires are a lot to push and the engine you/we have is 80HP. To my knowledge there are no performance parts for a LD28, and if there were, none would do any good without a turbo. In the USA none were imported with a turbo, so none of us here have any tricks up our sleeve.
The only thing you can do without a turbo is carry enough air in the tires to reduce rolling resistance, a clean air filter and choose a reasonable gear for the amount of RPM.
LD28 engines have a short stroke which gives a little more RPM, but is weak on torque. It is just the nature of the beast.

well, he's good good for highway use, but when driving in mud or up to clacier, it lacks a bit torque. Friend of mine has old 2,8 patrol engine in his range rover. But thats turbo engine. I allredy got a open 3" exhaust and a K&N filter. I also chanced the Diff ratio to match with the 38" tiers. Is it possable to chance the camshaft or anything like that? couse we usualy custom made things like that here in Iceland, also headers.
BTW, theese 80hp can push this truck up to 140kmh on hiway

That Patrol engine had at least 20 HP more than the LD28, right from the factory.
You'll have to add a turbo.

You might want to chat with someone at length that has scabbed an oversize turbo onto a little diesel already...you know... to save the engineering headaches.
I think a twin turbo setup would be really awesome! Can you imagine the boost two (11 Liter) turbos could make? Four maybe? Possibly some oversize headbolts? Propane injection? You may need bigger tires after all that!
Well, good luck, your gonna need it

Where the heck are you going to get enough exhaust to drive the turbine on that turbo that came off an engine almost four times the displacement of an LD28?
Have you considered the 280ZX Turbo retrofit?
