    Just to further complicate the situation, the 2.25 petrol came with either 8:1 or 7:1 compression! I can't find what the difference in power is, but it will be in the single digits (hp).

    I should probably provide a little more background. I have a 1964 SWB petrol car that I will be putting a 300TDI into with an r380 and series transfer case. Anyone that thinks it can not be done please save your breath.
    I also have already converted my axles to Range Rover ones and have vacuum assisted disc brakes on all four wheels.

    The aim of the game is to transfer the engine with evidence that the 300TDI has <20% power increase from the stock series 2.25L (74Hp).

    This way I negate the need for any major changes necessary with a engine swap >20% increase of power (collapsible steering column, 2 speed wipers, demisters the list goes on)

    There is no point going off the engine HP provided by Land Rover for the 300TDI as is over 20% power increase (111hp).

    Therefore.......



    In NSW if you want to be legitimate and get your car engineered you have two options.


    1 - Chassis dyno your series to prove its HP and then chassis dyno the 300TDI and de tune it to the required HP. This is fine however you would be starting off on your back foot as the hp figure the series would give would be depressingly low.

    2 - Engine dyno your 300tdi and "de-tune" it to spot on 20% power increase. This way you utilise the engine hp figures provided by land rover for the series to your advantage.


    I am now about to lock in option 2 unless, I can find someone with a peppy S2A SWB CHASSIS dyno figure that is around the 74HP mark. TIf I had that I could chassis dyno the 300TDI and de - tune it while the engine is in the car which is much cheaper.



    I hope this makes sense. The fact the 6 cylinder engine only came in the LWB model does not help my case.

    Cheers,

    Bill.

    They were a dealer option I believe not a factory option.
