TD42 Information

[nissannewby]

So the unichip is for the later GU TD42ti pumps? I am considering buying the pump from hall 4x4 but want to be sure. Or I might just wait and get the cylinder head first, rebuild the mote and then worry about the bolt on bits....
As or the heads. I can use and TD42 head? Blacktop or silver top? Some heads I see come complete ready to go. Would you recommend that or is there any work that I should, or could do to the head first? As for the power number I have said I am chasing, it was a figure I really just pulled out of my head as I really don't know what to expect with what different mods that are available. But I don't want to build a stock motor too, but at the same time, nothing too great as costs come with this aswell.



So what is boost compensated mean and do?
Sorry mate. This is a big learning curve for me....

Thanks for your input.

Yes the Unichip is for the TD42Ti.

Yes you can use any of those heads. However I would recommend using a turbo head. There are minor differences between them and since you are going to turbo then it will benefit. As for the head buy it (making sure its in good nic obviously) and fit it. New head bolts are a must.

Boost compensated is basically as Dale has described it. Obviously with a turbo you can dump in more fuel to make power. The compensator allows you to then control that extra fuel using a boost reference. So you basically end up with power and economy.

Really? Mine will need a rebuild eventually. Would there be much point in going 12mm on my setup?
Mine at the moment is a worn standard GU compensated pump
When diesel tec did the tune he said "there was play in the shaft and it will be okay for a while but will need a rebuild"
Whatever that means!

Just refresh the 11mm then

I should have worded my original post a little better. If you start with a NA 10mm pump then upgrading to an 11 or 12mm there isn't really much between the 2. If you already have an 11mm compensated then you have to ask yourself the question ben-e posed.

You can get the 11's built mate to then support even 150rwkw easily.

Probably means get it done when you can afford it for peace of mind mate. I had mine done when the engine was out being rebuilt. Also had the compensator added as it was a NA pump.
Unfortunately I seem to be dumping MORE black smoke than ever but I get the feeling it may have been a bad tune??

Who built the pump?

A bad tune will cause that. Do you know what the compensator pin profile is?

Any idea on a rough price? I know different shops will be different but just a rough figure to work with? I will go with Diesel Tec to build the pump.
150kw would be real nice, I have been thinking it will cost about 2k

12mm from Diesel central (starting with a gq pump) $2850. 11mm proba few hungy less.

You will have to discuss it with diesel tec and also see what he recommends he may recommend a diesel central pump.

I believe a DC3 which is a modded 11mm will set you back around the $2600 mark.

Is that to buy outright though or like an exchange type deal?

I believe that is on exchange mate. Diesel central do real good work hence the price tag that comes with it.

[Dales300exc]

Yes. Exchange.

Would this head be o.k to rebuild?
