• Hello all - advice required 1Z engine MTDi into T4 van...... by T4TD on 27 Jan, 2009 10:54
• Hi everyone.
  
  Having trashed my old TD engine one last time (bust piston), I decided it was time for a TDi conversion for my T4 Transporter van.
  
  I have a 1Z engine (now in bits) ready to build up, but wanted to replace the pistons with something stronger.  I am aiming to get around 120-150bhp when all sorted.  The van already has a huge intercooler fitted, and a new GT15 turbo was fitted about 15,000 miles ago.
  
  I am looking for advice on pistons, as have been advised to try ALH pistons, but interested in other peoples views..... Also looking at aftermarket pistons, such as Mahle.
  
  I have gathered a few pump bits, but need some advice there also.  I have an old AFN pump that had a bearing fail, and also have a good set of AFN injectors to use.
  
  Any advice/hints appreciated.
  
  Thanks in advance

• I'm planning on ALH pistons on my 1Z/AHU mtdi. If you want some extra insurance you could get the tops ceramic coated. Kolbenschmidts are a high quality brand. I don't think Mahle is too bad either but I could be mistaken.

• If you are looking for maximum strength go for the oil cooled dome version.
  
  I'm going to be ordering several sets soon and could put your name on the list. I have to warn you they aren't cheap.
  
  I also have TDI ALH pistons in Nural brand which are quite good, in stock in stock and .5mm over
  
  PM me if you are interested.
