I want to build my rabbit as my fun car. And track it. Since its already a diesel, i figured why not stay with it.
Hopefully in the next week i'm picking up a rebuilt (knurled pistons tho, ew) 1.6td and a junk (sheared crank keyway) 1.9.
The 1.9 is missing most of the accessories and the turbo/inj pump, but it still has the manifolds.
Don't know what it looks like inside, but the price is good. I'd most likely giles-ize the pump and toss in the 1.6, get the exhaust and intercooler routing all sorted, then build up the 1.9/2.1 slowly.
Anyhow. I read the thread that was linked a while back about the 2.1L aaz and decided to see if i could find those pistons. Well, thanks to ebay, i did.
http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=120347361616&ssPageName=STRK:MEWAX:IT (http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=120347361616&ssPageName=STRK:MEWAX:IT) It seems like these are 1mm oversize, so 84mm bore i suppose.
Apparently that price is for 4! And if the picture is to be believed, they include rings. I have no idea who the manufacturer is. Maybe someone recognizes the logo on the box?
I have been highly unsuccessful in finding out the height and wrist pin size (to see what rod i'd need) - anyone have any ideas where i could look for this info?
How cool would a diesel track rabbit be?? I'm sure its been done loads of times before, but i'd just love to kick some ass with a td rabbit.

It looked to me like that ebay link was for one piston.
-
it clearly states that the price is for 4 pistons.
-
My merstake, I didn't read it good enough.
-
its alright, the only reason i looked again, was because i, like you, was skeptical on the price.
-
i think theyd be 83.5mm stock bore is 82.5, im not sure tho
-
basically a 2.2 liter either way
-
the logo looks like they are MAHLE not 100% on that though if so they were o/e suplyers
-
how thin would that make the cylinder walls?
the general consensus is that a 1.6 block does not have enough meat in the cylinder walls to bore it out and use 1.9 pistons, I just wonder if the AAZ has enough to use the bigger pistons.
this also brings up the question, how much wall thickness is needed?
-
well hopefully soon i'll have a 1.9 to look at, and if that is indeed the price for 4 pistons, i'll order a set and see what happens. 150 bucks shipped for a set of pistons is dirt cheap, i might as well check it out. for everyone else's benefit at least.
-
I read the same thread and from what i can remember the photos showed very little left between cylinders and i think they were standard size pistons if that is the case those pistons would take 2mm from what little that engine had between cylinders think i would be taking another look at that thread? and check the liner thickness plus they have 10 sets available there not going to sell them in a hurry as those engines are just about obsolete over here {£50 each for a complete engine }
-
here's the picture again.
(http://zwalve.eu/d/1698-1/2100-07.JPG)
still looks like there's going to be a fair bit of meat between cylinders, but pictures can be deceiving. i have my 1.9 block now, so i'll do some measurements and post up the results.
-
looks that way with a copper h/g could be doable, will be interested in measurements
-
the issue is not the amount of deck left between the cylinders, but the actual thickness of the cylinder walls.
-
I agree that would be my concern ,any idea what the diameter of the stock aaz bores
-
stock is 79,5mm. why the ,5 is a mystery to me. even numbers are SO much better, but not to the germans, apparently
