Has anyone actually bought parts from there?

I'm thinking it is the same as e-miata, which I have bought timing tools from, but nothing else. The sites look identical.

jimfoo this might be a possible route for you.  punch out your block and sleeve it.  you'd get to re-use your original pistons  :wink:

Ummm, didn't you look at the pic of one of my pistons? I don't think a sleeve will help it any.

"HI, the problem is that the TDI piston is longer top to bottom than the
IDI piston and for that reason the conversion won't work.  

I am working on a 1.6 to TDI conversion, but I found special pistons
that will fit the block (and won't stick out too much).  

Pete"
Guess the answer is no, it won't work for me.


Does that only apply to the 1.6 though?

I bought 1.6td injectors as well.  Let me how they perform once you try them because i am just curious as the price is unbelievable.

does seem sketchy...  i thought i'd bite the bullet and take one for the team.   :lol: it seems like i have one injector that is sticking at startup.  funny though its seemed to have gone away recently.. (back to smooth startups?)

i had smog re-do my injectors with 160 bar with GTD nozzles... little did i know that the higher the opening pressure, the less efficient they are... oh well!

I had GTD nozzles done with slightly higher than stock opening pressure and they performed worse than a brand new set of OEM 1.6TD injectors (not reman).

Maybe advancing the timing a bit with the GTDs will have helped, but I doubt that would have recovered the 10hp I lost and add more power. Maybe I just had a bad set of GTDs, or increasing the breaking pressure was simply a bad idea.

i hope its the increasing of the breaking pressure although my timing is around 1.05 1.06-ish... maybe these el cheapo injectors will work good!!!  8)

Ok, I'm stealing my thread back for the moment.  :lol:  It does indeed appear that AHU/1Z pistons are the same as AAZ, so the conversion will soon begin. :twisted:  Question, should I post the details here in general or in the TDI section?

Here please :D

I'm not surprised that the pistons are the same since the crank is the same other then the nose.

Some questions to see what I can use and what I have to buy. Can I use my AAZ injectors? Are TDI cam, valves, lifters the same as 1Z? Also I've seen contradictory posts about using the AAZ pump in am m-TDI. Some say to just swap heads and cam plates, others say much more work is needed.
