TD42 Information

I'd assume that would be on a rebuilt unit?

Yes it will be rebuilt. If you have a pump built then the cost between an 11mm, which is what comes on a td42t, and a 12mm isn't much then you will have plenty of room to move and 150 will be a walk in the park.

A mechanical pump will be a lot easier. If you wanted to spend the coin and unichip it you could see some nice results but it will cost you. A good secondhand unit should be around 6-800. But knowing pump condition is like trying to know the condition of a secondhand motor.

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.

It does a little as they will charge you more if you supply them with a non compensated and want a compensated item.

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

Thanks for your input.

Boost compensation stops it dumping fuel in off boost. Reduces the cloud of black out the back while off boost.

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!

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??

Thanks mate, a good tune should sort that out. Turn the fuel down and you will blow less fuel, but may make less power... Need to find a happy medium!

Yeah. My biggest issue is I basically turned my engine into a turbo engine when I had it rebuilt. But no intercooler so can't up the boost to make similar power. Save save save. Lol.

How much power do you want

How much power do you want

I am happy with what I have but if more is easy to get without changing much more then....

Just refresh the 11mm then
