Just thought I'd post some pics of some engine conversions that I've been doing since the early nineties
at the moment there's a breakers I know well and have a load of damaged cars PSA's HDi's I can buy a low milage HDi without injection system for £100 , , So all I need to do is design an injection system for the job ,,,,
The campers below are fitted with = red one 12valve 2.1td we'll be changing the pump to bosch at the weekend ,, the other blue camper is fitted with a 306DTurbo engine xantia inlet manifold running underslung intercoolers ,
if all goes well will build an MTDi / MHDi for the 305 van

1Z's are cheap now some friends have these in there campers and to make them go as well as my Peugeot powered campers means the life is greatly shortened = I've built some hybrid injection pumps using pumps collected up from later VW TDi's 220/300bar , these had rods through the block or cracks in the block behind the flywheel so parts were really cheap ,these parts will be great to power the direct injection HDi , for these injectors to fit the HDi cylinder head 0.8mm to a depth of about 15mm then about 1.4mm to a further depth about 6mm needs machining , the lower portion is identical ,

if you got a bit of spair time i would make or get a pump bracket to bolt on to the hdi engine to take the landrover 200/300 tdi ve bosch pump and put the 300 injectors on to , you will need the same size cam pully (on hdi)to fit the bosch pump and maby a extra tencher/idler , the pump would need tweeked up for max revs/ power, injector spray patern may be a problem, 300tdi injectors are 230bar not shure the nozzle size

I've been building mechanically operated pumps - Bosch electronic type pumps like fitted to the VW TDi , I've built the pump and have some injectors from a BMW to fit the HDi engine
the pump bracket I'm going to use is from a pug D turbo engine
The pug van above is to be fitted with a HDi gearbox and 2.1 bottom end I think - just picked an engine up today , it took plenty of searching to find a 305 van this good , now has PAS and lecy windows
, just like another pals that had been a local delivery van warehouse stored fitted with 1.9TD ,

Hi, I've not actually tried bolting one on yet , I've looked at the casting and believe it will bolt on , I'll try one on as soon as I get chance
which is going to be very soon- blew head gasket on DTurbo engine due to boost gauge giving wrong reading and me turning boost up , I fitted another gauge and was hitting over 25psi

Hi, I've tried a couple of different injectors from BMW 320 to early transit connect , piston crowns are similar to vw tdi , compression ratio of this engine is 18.00:1 a 2.2hdi that I'm also building is slightly lower at 17.60:1 , the 2.0L hdi I'm building it to be a realistic 120bhp with 196ft lbs , In a pals unit sits a very clean 305 estate that the 2.2hdi might get fitted to , I'm after a lot of power from this engine
