    Thread: lets get a ABA 16v Parts List/FAQ Thread going

    1. 11-28-2004 10:51 PM #126
      if i were to keep the aba distributor instaled in the block i could use that with the stock ecu and all should be fine right

      You will still need the 9A parts, the PL (1.8L 16v) parts would work if you were using any 1.8L block, but for the 2L ABA you need parts from a 2L 9A.

      yes, you should be able to run it on motronic but it will be a little easier with OBD 1 than 2. You should have a chip made for it though, I hear techtonics makes them for ABF/16v ABA's, unless you are going with a turbo or supercharger them go with C2. You should make an adapter plate so you can use your OBD 2 throttle body unless you move the switches from it to a 16v one. You got the part about using a 16v cam gear on your intermediate shaft, right? Otherwise it wont turn at the right speed. Its a straight bolt on if you use a 9A intermediate shaft, otherwise you will have to mod the ABA intermediate shaft to get the 16v cam gear onto it.

      Wow, you just confused the crap out of me. LOL. It's hard to say but the pistons look like stock shaped JE's. I keep reading what you wrote and it's starting to make sense. Man I'm thick skulled. LOL. I want to get 8.5:1. I have to loose 2.'s of CR. Will deshrouding the valves and polishing the combustion chaber gain me some then maybe spacer it. Man, I hate to use a spacer.

      since you are going with a larger bore you could unshroud the valves all the way out to the new bore diameter, this should gain you some space to lower the compression but I'm not sure how much.

      how far can i go with this with a chip before the system is maxed i want to run some boost or high compresion and some serious cams not sure which way is better i need to keep the stock ecu so that when i get tested for emisions they can still plug the car in if not it will fail damn MD laws

      also your compresion ration depends on the head used either a 1.8 or a 2.0 the 1.8 will give the highe of the two correct?

      nope, same size combustion chambers and therefore compression.

      Ok, so I got my ABA engine tonight. I pulled the pan and oil pump, and the 16v oil pump and 8v oil pump are different. The 16v oil pump is driven by splines on its input shaft while the ABA oil pump is driven by a rectangle (for lack of better words) on top of its input shaft

      The C2 chips are being used with the kinetics turbo kit. I saw it put down better than 350 whp on a turbo VR6, so chip tuning has potential, but you should really sit down and figure out before hand what your total budget is and how much power you need. If staying NA then I would get some sport cams, a 50mm or ABF intake manifold and eurospec sport pistons. If going turbo a stock manifold or short runner, stock or a euro intake cam and ABA or 9A pistons. Remember when going turbo though, take your total costs of all the parts, add them up then double that number at least for your total budget.

      Well, you could try changing the input shafts, cutting the drive gear off the ABA distributor, or just leaving the distributor and living with it.

      I could, or I could just get a 9a oil pump. I dont want to screw around with the oil system on the motor that costs more than my car. Just not worth the 80$ or whatever a new oil pump it

      i1m not to familar with vendors were can i get the c2 at and whats the deal on the install and what kind of money you talking about for this mama-jamma

      has anyone actually completed this swap who can post pics of the process like the other swaps...

      So I have started on the dis-assembly of my 94 ABA motor. I pulled the oil pan off 2 nights ago and had a b!tch of a time trying to get the actual pan off. Turn out that there was a windage tray in there, and it is bolted up to the oil pump. So if you are pulling your pan, separate the pan from the gasket, not the gasket from the block.
      Ok, so next I put the engine on a engine stand. I removed the intake manifold from the head, no problems here.
      Then I took off the valve cover, and some sorta plastic splash shield.
      Since I am going to need to change the intermediate shaft, I figured it would be easiest to loosen the pulley while the timing belt was on. In order to get to the intermediate shaft, I needed to take the lower timing belt cover off. In order to take the timing belt cover off, I had to pull the crankshaft pulley. Now that the crankshaft pulley is off, I the timing belt is off too and I can't use that to resist the intermadiate shaft so I can take the pulley off. Then I look at the int shaft and notice that I can access it without removing the pulley.
      Ok, So now I pull the head off. Easy!
      I go to test fit the 16v head on the ABA block, and the guide pin is too big. So I pull/push the pin out of the ABA block, and put a pin in from my 9A block.
      So that is where I am. In need of a 9A oil pump and all the gaskets and headbolts, but I'm very happy. The crosshatching on the cylinder walls looks mint.

      pictures coming later!

      nice, would love to see some pics.. id already began to rip apart my aba, but i need to remove the 16v head from my scirocco. keep it comin.

    16. 12-02-2004 06:55 PM #142
      c2 only has 12v vr6 eproms and what not they dont have anything posted on the site for a 2.o

    17. 12-02-2004 10:59 PM #143
      Their site is a little behind, contact Chris or Jeff, you may need to schedule some one off tuning though depending on your needs.

      sweet thanks, what system does the odbII aba use motronic?? is the a way to by pass the second o2 sensor and just run the one with no cat.??

      With no further waiting, here they are!
      So last night I pulled the head and oil pan and put it on the engine stand. Today I pressure washed the block and painted it with black engine enamel. I also cleaned up the pistons with a wire brush, It was a tedious task, but the results are nice. I also put in the 16v intermediate shaft and pump gear and block off plate. Very easy job, there is 1 o-ring and 2 13 mm nuts holding the shaft on there.
      While I had them both out, I took some comparison pictures so you know whats up. There is a pic of the ABA oil pump below, and you can see how it is driven by the peice on the end. The 16v oil pump is driven by splines on that shaft..
      Here are the pics of everything.
      Here is the block after pressure washing

      Here is the bottom end, cruddy pic I know..

      Here is the block painted..

      Here are my pretty pistons, ohh so happy!

      Here are the intermediate shafts..

      Close ups..

      And lastly the ABA oil pump..

      Lastly, a pic for views, the assembled upper half of my motor..

      Hope that helps, and more information in a bit. Now I need head gasket and block gaskets before I can continue, and I am F'in broke!
      Later,
      Kevin

      nice pics, keep em comin.. i wont be able to start assmebly for a bit, still in school and no more money
      also, what the crap kinda manifold is that?? homemade?

    21. 12-04-2004 08:45 PM #147
      if you are using the ABA pistons, is it necessary to run a decomp head gasket? i think someone was saying that with the new head and the aba pistons it lowers the compression - but to be honest this thread mainly just gave me a headache
      and which gasket do you use, the aba or the 16v? and dont you need to block a couple of oil drain holes or something.

      When you say decomp, I assume you mean a thicker head gasket that will lower the compression? If that is what you mean, then no, you just use the stock ABA headgasket.
      What are your plans? Naturally aspirated or turbo?
      Basically, for n/a you want high compression ratio, such as 10:1, by using 9a pistons.
      For turbo, you want low compression such as 8.5:1. Look in my pictures above, you see how the pistons are dished? Those are stock ABA pistons in an ABA block. I am going 16vT so I want the lower compression of dished pistons.
      HTH,
      Kevin

      thanks for that. I am also wanting to go Turbo, so the ABA pistons would be the go. How much boost can you safely run with that setup?

      With the aba pistons/rods/crank and a 16v head, you should be able to run 15psi at least. You will need to go with stand alone fuel injection and stuff, but the mechanicals should be good for at least 250whp.
