I would have searched (I did manually search through 13 pages before giving up) but since the search is down.... Anyways, I'm looking for what might be needed to run an ABA block with 16v head. Also, how easy is it to retain the serp. belt setup? And what's the compression on a setup like this using factory parts. Thanks.

If you'd like to search again, look for "ABF" instead of ABA.

Re: 16v ABA info wanted (OhioBenz)
Just curious...
What pistons are you using in that ABA block with a PL/9A 16V head?
Any ideas on where to get a timing belt for less than ~$75?

I bought the Kent belt - ES $53.50 I am running the numbers though because that's a rip-off!! It's a stock belt in Europe! We just don't know the VW part number to order it from. There's no way that a belt that's only 1.5" longer costs 4x a stock belt.
The other solution is to run the 8v pulleys and buy a standard Gates belt which I have the PN for! Relatively minor mod work on the 16v cam pulley only - if you have an ABA bottom.

Thanks for the info. on the Kent belt.
If ABA (w/16V head) compression is higher than ABF (using "correct" pistons), then the timing advance maps in the ABA ECU may need revision. Maybe that's what he's referring to?

When you say "our" I'm assuming you mean the 9A code engine (2L 16V).Thanks for the info. on the Kent belt.

if you can get this belt let us know

Re: 16v ABA info wanted (Electron Man)
The ABA-16v combo has low compression because of the dished ABA pistons. The ABF setup has pistons that are the same configuration as the 9A except for the compression height and pin diameters are the same as ABA. ABA has a 30.9mm CH and a 21mm pin, 9A has a 30.2mm CH and a 20mm wrist pin. Hence the need for either custom pistons or modded rod ends (my choice)
Thanks for the VW number, I have had no luck running the number that was printed on the belt. My local little parts guy would love to be a US stocker of reasonably priced ABF belts

Hmmm, that contributed a lot of helpful information for the questions asked.Re: 16v ABA info wanted (OhioBenz)
All I ment by the statement was that the ABA/16v combo's are a bit of an unknown quantity at the moment, that's all. Until people start getting some hp numbers and comapring them, we don't know what this combination is capable of. Whether or not going down the path of the ABA/16v is the better choice compared to custom pistons with more compression, no one has real numbers to compare.

I'm not trying to enlighten anyone but myself. I just put the finishing touches on a 16v Turbo ABA block for a friend and the compression numbers we got were not promising. In our case we have compression numbers that are around 7.9/1 compression ratio. Knowing that the guys who make 550 hp out of a 2 liter 16v engine are putting out around 9.5/1 compression ratio with a very large turbo attached makes us wonder if if we are a bit low.All I ment by the statement was that the ABA/16v combo's are a bit of an unknown quantity at the moment, that's all.

Re: 16v ABA info wanted (130_R)
OK, I understand the CR might not have been impressive, but my basic approach is that the block/bottom end construction combo with a 16v head is on of the best 4cyl combos available to us - with a whole range of fueling options. Choice of pistons is dictated by your desired outcome. If you just want to make a simple bolt-on/in swap, then maybe that's not for you. If you are looking to build a very sturdy 4cyl engine that can handle boost or high CR, then I think it is.

If you are doing this conversion then the $50 cost of a belt is pretty small in the grand scheme of things. I went ahead and bought 2 of them.
