1.6 cy TD bottom end 1.9 aaz head project
« on: November 18, 2009, 04:25:57 pm »
Ok, well if you read the top then you know what I'm up to I AM GOING TO DO IT! seriously the audi 500o intake looks promising but I am open to better designs and Ideas I have the 1.5 rot assy and the 1.6TD bottom end still in need of the turbo, ex mani. downpipe? arp studs, metal head gasket, piping, intercooler, and odds and ends.  I am told that this is always talked about but never done well here goes I need cash and I have stuff up for sale/trade too so If you can help that would be just spectacular.

The stock 1.5ers.  Are they too weak?  I was under the impression that the stock internals are very strong just the 1.5 block is weak.  This information is good to know off-the-bat so I don't make any fatal errors during the build phase.

thanks,

First mistake, you can't use a TDI head with IDI pistons.

Custom.

Nothing matches between TDI and 1,5. Cylinder bore, rod journals, piston height, piston pin, rod length, all are different in stock parts.

E: 1,2L 3 cyl Lupo engine has 76,5mm bore and 24mm piston pin. Maybe you could use those.

Were you intending on a TDI or IDI? Because using the 1.9 IDI head would be pretty straight-forward.

going turbo all the way baby, I was told that the 1.5 rotating assy would fit right into the 1.6 TD block this is not true? I was misinformed? also veeery good to know so the question still remains where do I get said internals for the bottom end???  THe idea here folks is to build a high "for a diesel" revving boost hungry heavy breather turbo beast engine "like legos" with strength and some "I mean look at what we are trying to achieve here" reliability.

Thanks,

TDI or IDI head? Two very different things. Other easy, other not.

AAZ is not a TDI. AAZ is IDI. You're in the wrong section here, bud.

You want the next forum down on the main page. A 1.5 rotating assembly with a 1.9 head is gonna be some major cold starting issues with super-low compression. :D

so there is no such thing as a tdi aaz? I have seen them elsewhere too on the vortex.

You've got to do your homework before you start into a potentially impossible project. What people here are trying to explain to you is that the AAZ is an IDI engine. You can use the oem 1.5 pistons with this head. If you were to use a true TDI head, you would need to use TDI pistons. Meaning you would have to find/make some since there is no plug and play TDI piston to use in the 1.6 block.

There's a pretty good discussion of the 1.5 assembly/1.6 block/1.9 head idea in Saurkraut's thread (lots of measurements and considerations):
http://www.vwdiesel.net/forum/index.php?topic=11786.60

You may have to circumcise your 1.6 block to make it work.
Also, you'll need a 1.6 block that doesn't require boring because oversized 1.5 pistons are very difficult to find.  Someone was selling them on here at one point, but they were pricey.
