The only diff. between the ABA blocks are the crank and oil squirters. The rods are all the same from what I am hearing.

correct... 93 / 94 had the forged crank / oil squirts

[German_Muscle]

list updated.....Bump

[The Hater]

When using 9a pistons on the aba rods you have to get new rod bushings from the dealer to fit with your wrist pins.

[German_Muscle]

so when i walk into the dealer i need to ask for what specifically? ABA or 16v rod bushings?

[A3dOUde]

if you want to run mk3 access setup like I will do, need a custom crank pulley as Trac Racing are sellin, pulley for same conversion as the 1.8T in mk2 if I remember correct...

I'm startin setup this winter... keep you guys informed

[The Hater]

ask for 16v rod bushings. this is only if you are going to use the 9a pistons, and aba rods. in the end you'll have 9a pistons, 16v wrist pins, 16v rod bushings, and aba rods...

Word is you use the 16v crank pulley...why do you need this custom one exactly?

[all-starr-me]

the timing belt and pulley is wider with the 16v one on there so for the serpentine pulley to line up with the accesories and belt 6mm needs to be taken off the sepentine pulley.

[A3dOUde]

well on mk3, you have the T-Belt crank pulley and another pulley for accessories.. but since the 16v crank pulley is wider, you need one custom made so everything lines up as stock...

[Flat Black]

Good to see you started a list for everyone to go off of. You can also do the ABA Serpintine set-up if you want to.

PS: You have IM.

[junkyardjockey]

What CR would you end up with;if you used the 9A pistons in the ABA block???

[MA_XXX]

9:1

[German_Muscle]

what about if you use ABA pistons and stack 2 ABA headgaskets? ~7.5:1?

What about motor mounts? all the MK1 motor mounts will work with this swap right? i have a poly front motor mount. Thanks

[The Hater]

Yah..all the mounts will work in a mk1, the 16v blocks should also have the provision on the passenger side of the motor for bolting up that motor mount. You'll also have to get the bracket for the trans..both the rear trans mount and the side trans mount.

[need_a_VR6]

Anyone here figure out a good way to cut valve reliefs with the pistons in the block? I'd take em out, but then I'd re-ring it, new bearings, etc and I don't want to go down that road.

[mwebb95jetta]

Is there anyone out there that sells this conversion in a kit? Im a little confused the parts list shows that you must use the 16v pistons but everyone talks about using the aba pistons? I undestand that the aba pistons will give you a c/r of 8:1, so assuming that the 16v pistons arent the same what cr do they giv you?

[German_Muscle]

no there isnt really a kit out there. You just kinda haft to do it like this. It gets very confusing sometimes to. Im going to use the 2L 16v pistons because im going to run it as natural aspirated for a while and because im using a 16v head. you can run the ABA pistons to if you want to keep your compression ratio to a minimum. It all really depends on your preferance. The 16v pistons are flat tops with 2 valve indentions for the intake valves. the ABA pistons have a bowl in the piston. Here is some pics.

2.0L 16v(9A) Piston

2.0L 8v(ABA) Piston

[mwebb95jetta]

So then the list that we have above is for a na setup.

[German_Muscle]

no, not really. im running N/A because lack of funds, next summer i will be bolting a SC61 to the engine with a few other goodies like Autronic. the ABA pistons give you a lil bit lower compression ratio thats all.

[mwebb95jetta]

so right now you have the motor runnin on 8:1, and it runs good?

[German_Muscle]

its not running yet, but yes it should run good, its not going to be fast but it will run fine

[mwebb95jetta]

which charger are you gonna be running the SC61. Who makes that one. sorry im just starting to get into this project and i havent looked much into forced induction besides the BBM and the neuspeed.

[German_Muscle]

the SC61 is a Turbocharger,, it is about equal to a T61. Here is some info on it. http://www.precisionte.com/pro...rgers

[need_a_VR6]

it is about equal to a T61.

... but with a waay more efficent compressor wheel of the GT family.

[mwebb95jetta]

link doesnt work but oh well I think im gonna with more reliable source of power,supercharger. I wouldnt mind going turbo but dont want to shell out the cash.


Modified by mwebb95jetta at 7:58 PM 8-20-2004

[The Hater]

what supercharger do you plan on running that is both reliable and more cost effective?

[mwebb95jetta]

Well before I was thinking about doing the 16v head swap, I was going to get the Neuspeed, but havent really thought about it since I decided to do the head swap.

[mwebb95jetta]

bump for a good thread

[Cabby-Blitz]

Does someone have a picture of the 9a IT shaft gear?

Want to see the diff. between the 9a and the ABA. Cause I want to see if I can do some work to get the 9a gear on the ABA shaft so then I can use the ABA oil pump and not have to source all of the 9a parts.

[A3dOUde]

for piston, if you don't need to oversize bore dimension, juste find a euro dealer that may sell you some 82.5 x 92.8mm 10.5:1 CR ABF pistons...

btw, I've got a quote for VW oversized ABF 83mm x 92.8mm 10.5:1 at 1400$cdn + shipping and taxes....

still don't know what to do

[all-starr-me]

Eurospec sports has cast ABF pistons for the ABA to give you a 10:1 ratio for $289 usd. if you want a 10.5:1 you could deck the block or head slightly. They also have pistons for use with 83mm and 83.5mm bores and 95.5mm stroke for a little more money. Use the money you save to buy some aggresive cams from autotech or TT.

The ABA pistons will give you an 8.1:1 CR and the 9A pistons should give you an 8.5:1 CR, both are good for boost.
