Title: TDI bottom end, 1.6 head?
Post by: hamradio on April 22, 2009, 08:08:07 pm

So,


From what I understand, I could get a late '90s 1.9 tdi bottom end, aaz pistons and rods, a 1.6 head, throw it all together, and it would work?


What would the CR come out to?  Would I have to use a hydro head, or could I use mech?  Additionally, could I use an aaz head?



Lastly, would the block have provisions for a normal IP bracket to bolt to?



I ask this, because I could get a 1.9tdi block from a car that blew a tbelt for cheap.


Thanks.

im no expert so i wont say that it will  or wont work.

but what we all know is that the 1.9 is better then the 1.6.

i myself would not be inclined to use a 1.6 head on a 1.9 bottom end.

Thanks.  I think the bottom end is an AHU, but *might* be an ALH.  Is there a difference between them?  How strong are the stock tdi rods vs aaz ones?

D'oh.


Would it be the same with aaz pistons as it would with tdi?

wasn't there a 1.6 upgrade to 1.9 by just using the bottom end? a little counter productive though because the 1.9 head flows sooo much better...

Would the 1.9 head do alright?

yep.  the 1Z/AHU is nearly identical to the AAZ other than some of the internals.  jimfoo turned his broken 1.9 AAZ into a TDI by just adding TDI pistons & head.  he even used the AAZ head internals in the TDI head and it worked.
