the p100 diesel is an odd one , it basicaly the same engine as all the TD's but with a better pump and turbo on !

it will fit but will probably need a few things changing like mounts , alternator bracket , thermastat housing , flywheel , bottom pulley , downpipe from turbo , sump

when you get the existing engine out just put them side by side and go around the TD lump and make it look like the one thats come out but with a turbo stuck to it !

everything is interchangable between the 2 engines so its just a case of seeing what is different

as for the dumpvalve - a convenctional DV wont work as the intake never goes into vacumm (which is required to open the valve) , its possible to fit a electonicaly opening valve and a switch under the clutch but they are pointless and sound crap

i was playing about with mine and can get turbo chatter by fitting a throttle body from a petrol where the IC sits and closing it with a cable , it forces the air thats produced to go back through the turbo and causes chatter , again totally pointless and was soon put back to norm !!
