If it doesn't go with the auto box, can't see it would be a lot better with a manual box, better to swap or fix the engine IMO.
How early is the box? If it's a ZF4HP22 it will have torque convertor lock up. No big diference in fuel consumption and they mask a lack of low down torque nicely.
Yeah i know. Thing is he says Mazda/Perkins. Now i know Mazda made a few Perkins engines under licence. But seeing as how Perkins as far as i am aware, have never made a six cylinder three litre engine. Think it maybe a pure Jap engine. Perkins are a work horse engine with a stroke longer than Kate Middletons legs. They are or were not, when i had dealings with them, something you would fit to go to a sprint meeting and hope to take a prize.
Had a mate who was putting a P6354T into a Mk 10 Jag running it through an E type g/box and a Yanky diff. The diff housing had to be built to fit the rear subframe. Don't know if he ever finished the project as we lost contact. Working out the rev's and ratio's on a slide rule (it was in the seventies) he thought the top speed would be over 150 mph. He had a scrapper and bought a new body shell for £420 from the main dealers in Chester when they were clearing out the spares dept.
As far as i recall the 6.354 5.8 litre straight six only revved at around 2800 RPM absolute max. So he must have fitted a hell of a diff for 150 MPH.
Quite correct that's why he went for a Yanky one. It was the 6.354T (turbo) and I must correct myself, it was a 5 speed ZF he was fitting. The E type g/box was mated to a 4 cylinder Perkins 4.203 I think that was in another Mk10 that he used as his daily runabout.
I have seen them fitted in a Rangie years ago, not the turbo engine, just the na version.6/354 were a great engine, not really about speed, but great low down torque if you can keep the halfshafts and diffs intact
4/203 must be seriously underpowered in that application I would have thought.
Great times
Only guessing at the 4 cylinder engine, it certainly wasn't the 4.108 ha ah. It was 3 ltr or above and could show a clean pair of heels to a normal family car and return 30 mpg. The gearbox had o/drive as I remember. I also saw a 6.354 in a Classic, it had an extended nose, twin headlights and two radiators fitted at the side of the engine (like the single rad on the 6 cylinder VM). I put a BMC engine in a Vanden Plas 4ltr R with a manual g/box, 4spd o/drive and free wheel out of a Westminster 6/110. 54 to the gallon, better than the 9 with the petrol engine.
I have had 4/203 before, as you say, they are very economical, and so much torque they weren't bad off the lights, but very slow top end. My s2a had Ascroft high range tranny box, some had Fairey o/d instead.Welcome To LandyZone, the Land Rover Forums!
