ok I'll try it here. Canadians? Europeans?

Would like to use this mk3 AAZ pipe on my 86 Jetta 1.6TD. Has anyone ever done it?



thinking there's a chance the pipe could hit the rack as the AAZ is a tall block. if this works it would be an economical solution for rusted cast iron exhaust elbows and downpipes.

that is exactly what I am using in my '92 jetta with an AAZ. Don't know if you'd have a clearance issue using it on a 1.6, but I don't think so.

any idea how much clearance there is where it goes over the rack and subframe area? if it's more than an inch it should work on a 1.6

Jezzie has a 1.6TD with an AAZ downpipe.  It's in a Mk III body though so not QUITE the same.  No issue though.  There isn't THAT much difference between the A3 and A2 bodies.

mk2 and mk3 sub frames are IDENTICAL.. rack positioning, everything.. the axles and control arms are what make the mk3 wider..

Mk3 subframes require a different rear motor mount.

But is it in the way of where the mk2 DP would usually be routed?  If no then sounds like it would work just fine.

no they dont REQUIRE a different mount.. you can run a late mk2 motor mount in a mk3 sub frame, or a mk3 mount in a late mk2 sub frame. its the same mount even, it just has one big bolt hole, rather than 3 little ones..

and no, the motor mount has NOTHING to do with how the downpipe fits, its about 6" from the downpipe..

mk2 and mk3 sub frames are IDENTICAL.. True or false?  Yes or No?

[R.O.R-2.0]

the actual sub frame, JUST THE SUB FRAME, is the same piece, between mk2, and 4 cyl mk3 cars..

so.. its TRUE.. they are the same. like i said, its the axles and control arms that make up for the difference in width..

how on earth would you bolt a VR6 subframe into a mk2 if they were different? because you can put a VR sub frame into a mk2 with no other mods, besides denting/notching the frame rail to clear the VR crank pulley..

i stand by what i said.. besides.. this part of the discussion has NOTHING to do with the OPs original question.. we are getting way off track here..

Thanks for the clarification. 

[ilikevwdiesel]

thanks for all the replies. all things considered, the only difference in geometry between a mk2 1.6 TD and a Mk3 AAZ (with K14 turbo) would be a slightly taller block on the AAZ. So the downpipe in the picture should (technically) be slightly longer on the vertical. if this is in fact the case, the only issue would be the potential for the pipe to be too close to the rack or the subframe. hopefully Patrick will look at his mk2 AAZ car and see if there's plenty of clearance in that area. I had one of those pipes at one time but it went with an engine I sold.

[CrazyAndy]

IIRC the AAZ longblock is about 3/4" taller to contain the longer stroke.  That's what Theman53 told me, and if that much less room it to hit the rack then it looks as if it could be made to fit by taking out the 3/4 between the flange bends and the flex hose.  I don't know if the DP support that bolts to the exhaust manifold would still reach, though.  Maybe if it was turned a little bit to point to the closest it gets to the pipe a fat weld could tack it on.  Either way I definitely agree with you: stainless steel flex > cast iron toilet bowl.

I stuck one of these on my cars. It was a mk2 beater of beaters so even if it was rubbing, I never would have heard/noticed.
