    4BD1T MSA5G Range Rover Classic Outcast Adaptor

    I'm at the stage of making the chassis engine mounts and need some advice on setting the engine height relevant to the chassis.

    This means that I have the engine, gearbox, adaptor and transfer case all bolted together - transfer case sitting in original position on its mounts and the engine end suspended by a crane.

    Before taking the v8 out I put a straight rule across the bump stops and measured a gap of 70mm between the rule and the bottom of the sump. Have people set their 4BD1's to the same gap, or to gain bonnet space gone smaller ie 60mm or 50mm?

    Note I have the body off the chassis at this stage so its a bit hard to judge head room at the bonnet. I reckon I could get the engine in at 70mm and probably have bonnet head room without a 2 inch body lift - but those with experience I suspect will say you need the body lift.

    Has anyone modded the bonnet ie cut the interfering section out and raised it like a bonnet scoop?

    And yes, I'm taking lots of photos for later presentation.

    Take the springs out to help check clearance. I have no bonnet mods and 1 inch longer bump stops. With stock bump stops the front diff hit the sump corner on hard impacts.

    Thanks Dougal.

    I did wonder about extended bump stops - I assume standard bump stops are mounted on a steel extension block - or can you actually buy longer rubber?

    Likewise, I did wonder if the corner of the diff pumkin would contact the corner of the outer edge of the sump.

    I was thinking that putting a rule across the bump stops and measuring the sump-to-rule distance would have sufficed and just set to original v8 distance. But I guess taking the springs out would show the degree of bump compression, particularly considering the extra weight the engine imposes.

    Did you go to the trouble of a 2 inch body lift? This vehicle came with a 2 inch spring lift only, not that the spring lift has much to do with the chassis/engine position relationship.

    My starter motor has probably 10mm clearance from the chassis. How close is yours?

    Thanks AM.

    Don't know if Defender and RRC bonnets share same chassis distance.

    4BD1 is set at 70mm bump clearance as per v8.

    Going by your suggestion I get 525mm.

    Do you think 5mm mallet dent in bonnet would be noticed?

    Quick look over first pages of Onheit - very nice work, but umm...it appears your turbo is on the drivers side while mine is on front passenger side. Is this correct?

    I don't know AM...I think you may have proved something anyway, about the relationship between the two vehicles.

    Just read a bit more of Onheit to see yours is a 4he1 and explains the turbo.

    No body lift, the extended bump stops I have are orange poly. Packing then down will have a similar overall effect. You have to allow for about 50 percent compression, letting it just sit there isn't enough.

    My starter is the compact 24v and my chassis is notched. Would likely clear static but touch in motion without the notch.

    I could try post some engine bay pics of mine, it has a body lift and top mount intercooler. Engine is in standard isuzu series3 position.
