fitting g with turbo
Hi to all here i have posted some pics of the turbo i fitted last weekend can anyone tell me what the other bits are and where they go it's worse than a Rubiks cube!!!!!
thats a better picture the first pipes are vaccum pipes that control auto gear box and engine stop etc one does go to turbo thing with shinny top ive disconected this so none of this stuff is relevent to turbo .thing in middle sits on top of rocker cover and works with throttle linkage to swith vaccum pipes on and off (i surspect turbo has come off a automatic )the other pipe looks like the one from the manifold back to the fuel pump .i'll get cammera out tonight and try and show you . good luck
Hi the pipe with the flange fitting is the oil delivery which attaches to the place where the two bolts are screwed into the side of the turbo ..the other end attaches to a right angled fitting underneath the oil filter ( you will have to remove the oil pressure sender to fit the "T" fittting....the other pipes look like part of the emissions control system as fitted in the United States..you will not get peak performance with the original 300D exhaust.keep the new pipe bore as large as the flange at the rear of the turbo all the way..a side entry single muffler helps.once you have got it all plumbed up you can put a boost guage into the output side and set the wastegate for optimum boost...if your engine is not the original OM671A keep the boost well back..you will have to set the injector pump timing to give you more fuel on a non OM617A engine....
That thing on the right is the 'overboost' protection valve. One end plumbs into the manifold, goes to the valve, and then to the top of the ALDA on the injectionpump. If an overboost is sensed, the valve will open and thus exposing the alda to atmospheric pressure and so reducing fuel.
(I think......)
Anyway, it is a safety thing. Will dig out more info later

oil pipe at top
oil pipe into sump
pipe at back of manifold which goes to the alda /when this pipe is disconnected power is not there i never got pressure sensor with mine , kashi123 i thought waste gate regulated pressure is this switch there if that fails ?
this part is emmisions control an i have disconnectrd it it did run to vacum switch on top of rocker cover i used the one of the original engine as it was easier these switches con trol auto gear box . hope this helps but as you may have gathered i am no expert and if any one know better i would be only too glad to here
Here explained far better and by someone who knows what they are talking about:

Richard looks like i will need to get a pressure switch i did wonder what they were on photos of other engines .blooming heck my spelling was bad earlier was rushing though
thanks jeremy
thanks 4 all the help lads im goin 2 look at it this weekend will lit u no how its goin
You will have to instal an "oil return" pipe from the base of the turbo to the sump...to avoid bits of aluminium falling into the sump pan when you are drilling the hole for the fitting it is advisable to remove the sump pan....fine particles of aluminium in hot oil tend to clog the oil galleries and can result in major /terminal damage........
