its aford not a nissan wrote:20 psi is normal for the TD42 hot at idle...........no problem to fix

Agreed... its fine, if it worries you put 20-60 in it

many thanks gives me a starting point

As above I have a T3500 Mazda truck 3.5L 4cy . Have just rebuilt the engine, and following a bad idea of putting a ebay turbo on it Im keen for a smaller turbo. So my question is, what size turbo?? Seems to be hard question even for MTQ. I would like boost of 8-12psi by 2000 Rpm, keep in mind the ...

and from my experiance. Snap there goes a crank!!!. But that is pretty good from an old SD i must say!! Thoughts KiwiBacon? Looks quite good. Torque figures are about what they should be so no-one is playing silly-buggers with the dyno settings. Those SD33's must breathe quite well to provide 118kw ...

I wouldnt say it needs a rebuild at that klms, before buy it, take oil filler cap off at hot adle and check how much blow-by there is. I asume its a MQ non turbo with a turbo fitted??? putting a turbo on a non turbo SD wont shorten its life as they are the same engine, (some will argue the point ...

ok am probaly get someone to rebuild the whole thing. i am looking at Warby engines in cranburn has anyone used him or heard anything about his work. seems like a good guy. John is great, knows his shit and does it well. We use warby for all our machine work. He did all the machine work for the 2 ...

agree blockage towards tank somewhere

i did one for the SD but it replaces the heat exchange all together. In hind sight it was a bit of a fizzer. If u still run the heat exchange remove the cast alloy pipe from the filter housing to the heat exchange. Just run a tapper tap in the the housings fit some JIC hydraulic fittings and het ...

something must be wrong with the system, it should under the right conditions go into self clean mode which literally dumps lots of diesel in to the engine. Cant remember if the navras injectors overfuel of it has a injector in the DPF. The excess fuel burn hot and should burn up the particulates ...

I will say a balanced motor does make a noticeable differance at high rpm, when i rebuilt my old SD33T i got the rotating assembly balanced and did the rods and pistons myself. All though this was to try and stop it breaking cranks but in the end it was decided that they are just poor design with 4 ...

adaptor plate for T700 holden auto. Had thought about this a lot, a few years back, even had some drawings of plate and torque converter/flywheel, never got around to it. then adaptor plate for transfer, or the remote mount. Bought a GU td42t after 2 broken SD33T cranks.

All good info. Yes turbo pump is bigger. N/A oil pump only has about 30 psi pressure at max torque around the 1800-2000 rpm. But when fitted to a N/A the power is around 3000rpm by that point it has it 50psi. Althought a very wide bearing still didnt do mine much good, shells were marked after only ...

thanks marc

factory 6psi, cant see 10 being an issue but i had to ask the question given the trouble ive had.

NOTE use nissan rear main seal!!!! Bit harder to do it in there rather than upside down in a stand.

Turbo oil pump is bigger too so have fitted 1 since i have a N/A block

As stated who uses a SD for towing at 10 psi boost??? As you all know towing at 20 psi did not work well for me! Plan on towing 16' caravan around for 6months, between Vic and qld. Basically has anyone had any engine trouble at this boost level. As i dont fancy another 2 piece crankshaft. Cheers ...

Eng Aus, 1300 364 463 Should be fairly cheap. but having rebuilt a few RD's the cranks crack sometimes. I did a customers after a t-belt failure, pistons rings, brg, head o-haul, basic in chassie rebuild. Only to have it spin No. 2 bigend after only 800klm. Apon dis-assembly of eng sent crank out ...

Very worth while conversion. All as Wicked said, use 2 holes and make up and weld in crush tubes for the others, Vee out top of rail for one bolt. Can very easily fit up TD pump aswell.

In my experience i wouldnt bother again, Let it over boost by a few PSI will keep the egts low..

But yes the link suggested by coils is a very good and decritptive post

sounds like a buggered ring, cracked pistion yes. Like you said a rooted valve wont pressurise sump. Just squash the top of dip stick tube so it stays in!

search is your friend.. All is possible 24 to 12 is a bit of a pain. I found it easier to swap over wire looms. but each to their own. All bulbs, motors, dash cluster needs to be changed. Just swap shafts with from donor, diffs should all be the same, unless by some odd chance you got a c200 in the ...

Cam specs found little card, BUt not sure on what std grind is Was about $200 for cam grind and to face the 12 cam followers Running Clearance" In .014" Ex .014" LIFT @ LOBE: In .283" Ex .283 Advertised Timing Ex Opens 65 deg Closes 29 deg In Opens 19 deg Closes 74deg .050" Valve Timing Ex Duration ...

I think the shifter tops are different between the factory L28 5sp and diesel 5 sp
I stand corrected if im wrong. No not to much trouble to swap

Each to their own with addatives I think.

Update. Fully rebuilt SD factory tune till run in, wholy shit EGTS out of control. 620deg post turbo up a hill!!!!!!!!!
Could this be a down-fall of a lumpy cam??
Yes pump and injectors have been done, cost me 2500$

Clive Cams in Furntree Gully VIC. Did an awsome job,, when i say custom, the hard facing was coming off mine and i gave it to him and said if you can make it lumpy do it, if not just fix and std grind. Like i said i think on a SWB big boost is ok. Small car not on boost all the time go for it crank ...

Cranks,,, This is an old thread. Got mine going on saturday. After much deliberation it was seen that the crank/block are of poor design with only 4 mains to hold the thing in. After another crank was found we talked about treating it. But it came down to the crank gets a bad "whip" up in the front ...

Vanne, check your damper, just pull one end off and see what its like, should have a fair amount of resistance. Dampers only cover the real prob. Could also be loose king pins, or if using extended shackles and castor may need adjusting. Jack up and drop the tie rod ends off the knuckles and turn ...

Try engines australia. i just bought a SD33T kit including liners from them for 900$ TD42 was not much more i dont think

to go v8 u will need a bellhousing, if you go RB you can fit a L28 input shaft and bell housing. RB will bolt to this box will be on a lean and small mods on top housing bolts. I have no idea on cost, RB may be the cheapest option if using all used parts at the right price. But injected RB then has ...

what patroler said. I doubt its too advanced, up to 3mm past the marks on the towards the drivers side will be fine for an SD, this make up for worn gears and advance unit on pump drive. A diesel thats too advanced will blow white smoke and have a real death diesel knock. A way too advanced diesel ...

sounds like the delivery valve on the injectors pump is playing up. I take it you didnt swap injectors as they are the same.

Since all you did was add a turbo and manifold plus injector pump the prob must be there some where. Silly question no stray rags stuck in the intake???

Rabs From my experience both motors are pretty much the same. Oilers under the pistons. Heat exchange on turbo motors are a little bigger, post 83 had fine cut timming gears to reduce noise. All items will fit. Yes there is a spot for the turbo oil feed in the N/A block, just above the ALT oil feed ...
