building an MHDi ( MTDi ) 2.2hdi

[famous phil]

  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

MTDI pug hdi i would love to see that   pug idi injector brake psi 140 bar , hdi 2000 bar ish and the hdi is about 7 stage injector too,
the pug engine sits in there nice , 1z tdis are cheap now

  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

Forget the engine, I want that 305 van!

  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 ,

Does the XUD mecanical pump bracket bolt right on to the DW10 HDI motor??

[famous phil]

  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

Heh i see 35psi daily on my XUD...

  been quite busy with other work , the campers still running with D-turbo lump just tightened head studs to F,T ,just got round to fitting the pump bracket  two bolts fit - one mount point needed machining other still needs  looking at ,

 pumps fixed in position, been trying to find a suitable set of injectors , bmw 320d fit and are two stage but might need pipes making ,, found some better injectors being shorter so have pipes that fit  , will check out some more when I get the chance whilst looking for a better turbo

    :)machined up another set of two stage injectors to fit ,
 Set timing up on one of my MTDi pumps , bled injectors and this is the first start up , I'm really pleased at how she sounds , sits nice and steady , just need to take this in to my factory for finale build up + fit new fuel injector pipes , pos variable vane turbo or twin turbo ( in readiness for bugjam :rolleyes: ) , then fit adaptor plate to fit my T25 / T3 camper as still designing machining parts for new high ratio gearbox to fit  ,

[snakemaster]

some nice work there what injectors did you fit to get her going , does the hdi engine have the same cc cup in the pistons as the vw tdi ,what is the CR of the hdi.  what power you hoping to get

[dts67]

Great work mate, really admire this.

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
