My turbo is now on!!!

[johno90]

I finally had a weekend spare this week so without delay i jumped right into fitting my turbo.

As some of you know im doing it all myself using a td05 20g turbo and water to air intercooler rated to 600hp.

Bolting up the turbo and manifold was easy as, making the dump pipe was more of a challange cause i refused to go less then 3" pipe i had a absoltutly no room between my exhust housing and firewire, after doing some angle cutting and guessing i finaly got the 3" to fit :) with about 2mm clearnce :P

Drilled holes into lower thermo housing and upper thermo housing and tapped out to fit dash 4 adapters for the cooler lines on the turbo, oil feed was from spare bung in the block and fitted a barb fitting to the sump.

Todays mission is to buy some silcone bends for the intake piping, fingers crossed someone has what i need. once i get the piping sorted and postioning ill mount the intercooler. The heat exchanger im mounting to the bonnet with a decent scoop and fan.
Finaly if i feel up to it ill make the exhuast a bit longer then just a dump pipe :P

I do have pics of everything but it says upload failed everytime i try it :S

Top effort old mate!!! That much more satisfying having a lash yourself so well done.

I do have pics of everything but it says upload failed everytime i try it :S

Looking forward 2 seeing the pics.

Check file size of each image, anything over 1.9mb will give above error.

I use this program to resize images: http://www.fotosizer.com/

If you still can't upload after resizing images send me a PM

Cheers

Thanks for the program!! works mint

Heres some piccies, will get more once all plumbed up. god i hope repco or autobarn have the bends i need. i dont want to drive to work tomorow with just a turbo spining around doing nothing :P

Hows 550 degrees sound for pre turbo? looking to tune it to about that.

[bazz61]

good effort mate , im going to turbo my 2000 ute , its a black top same as yours , just a note , does the motor pistons etc need modifying to handle the xtra heat etc & horse power??

[johno90]

2000 black top has completly different internals then a 93 black top :) if i was you id change your internals first.

Anway its all going, went for a drive goes ok, will be better with cooler finished and boost turned up.

Pyro seems a bit dodge tho its brand new autometer one but if iwiggle the resistence wire goign to the sensor it jumps up 100 degress

[moose maverick]

Nice job mate, did you buy the gear as a kit or source it individually? I'm currently in negotiations with the minister of finance and recreation to purchase a kit to breath new life into my 500,276km NA TD42. Nothing like the noise of a charged pooey diesel!

[MC97GQ]

Hey Johno,

Nice setup, quick question where did you get your new manifold did it come with the turbo or did you source it separately if so how much and where from, I'm looking for a new exhaust manifold for mine as I'm not real happy with the one thats on it.

How did you go with the plumbing, Repco are hopeless for bends etc, Supercheap or Autobarn are probably the better option.

Let us know how you go I would certainly like to see how the setup goes.

[johno90]

i got my bends from autobahn and super cheap. as for turbo i bought all the parts separately, manifold is off ebay cost me $350 and is a good design nice flow and has external waste gate cast on it which i used as the pyro spot.

Car has heaps more grunt tho i do have a couple of probs, my wastage is slightly opening causing it to only make 9psi. Also getting very heavy diesel knock under load which i never got on my last td. pump has been wound in 3/4 turn.

Turbo is pretty damn big doesn't come on boost till at least 1900rpm but between 2300 and 3300 its like getting punched in the balls. i plan on properly tuning it once i fix my pyro and finish installing my water to air cooler.

[nissannewby]

Sounds like your timing might be a touch out have you inspected it to make sure she is right?

[johno90]

Na I haven't, don't have a dail gauge to check it. Thi I'll see if I can borrow one. Does anyone know what timing should be for having a turbo on it

[nissannewby]

On the GQ's i think its about 0.76

[johno90]

Is that standard or a setting for use with turbos

[no eye deer]

Recently saw .84. I'll try and verify that though..............

Mark

[no eye deer]

Flounder!! .82 sound better?

http://forum.ih8mud.com/diesel-tech-24-volts-systems/520211-downside-advancing-timing.html

[nissannewby]

I would start at 0.76 then go from there only going at 0.01 at a time.

[johno90]

Hey all, got it running 15psi now, waste gate was slightly open. still getting diesel knock tho not as bad buying a fail gauge this week to check timing. will start at.76 and go up from there as newly said, should i just keep advancing till it doesn't knock??

[nissannewby]

It will be more likely to knock the further you advance it as it will end up with pre-ignition it could be to far advanced as it is and may need to be retarded a bit.

[Bambill]

Nice setup.
Could you tell me the number on the turbine housing?
The extra engine noise (diesel knock) could just be from all the extra exposed pipe work you have now.
Mine sounds like a direct injected engine in the lower revs, but it is advanced a fair bit.
700degC pre turbo is still a safe EGT. 550 is very low.

[johno90]

I'll get the number for you when Im back at the car next, I can't even get my egt to 700 fuel maxxed and driving hard, my cooler works super well plus cause of the turbo size it's still extremely efficient so it doesn't heat the air to much.

[Damian_74]

Hi Johno,
That charge air cooler looks interesting – where did you get it?
I am looking at doing something similar?
Some more photos of the finished product would be nice.

What is the charge air temperature after the cooler?

You can overcool!

If the temperature drops below the dew point (remember to take into account the relative pressure), the water vapor will separate creating thermal efficiency loss, possible cylinder lubrications problem and cold corrosion (more relevant when using high sulfur fuels – forms H2SO4 , Sulfuric acid)

[johno90]

Got it from the states. my heat exchanger runs a thermo and electric pump and I've added a control so it keeps air temps around the 30-40 C mark.

Will get photos next weekend of it all in its finished state.
Just to add it is really surprising how much people underestimate the output a standard injector pump can give, had some guy lecturing me on 110 kw is all it can do, i just felt like slapping him around abit. People seriously need to learn to shut u if they really don't know what their talking about, I'm sorry i have years of experience doing these mods and you just tried it and failed yet you somehow know allot more then me (End Rant)

:)

[nissannewby]

110 kw at the wheels is pretty good if thats what he was talking. I do know a few people who have maxed standard pumps at about the 160hp at the wheels, this is with fresh pumps. Anymore than this and you will be need to look at bigger pumps. If everything is working well you may and is all fresh you may be able to push the 180 mark

[Bambill]

I would seriuosly ignore the post above about overcooling the intake charge.

[johno90]

Well its all on now, wound the pump right up and was extremely happy beating a worked GU td42t :) :) get seem to max out at around 550 pre turbo. next step is to get it on a dyno and view some real figures.
