      I have not been on this thread for quite sometime. I can't wait to start getting all the parts I need for my AEB/ABA crossbred setup. [IMG]http://**********************/smile/emthup.gif[/IMG]

      thank you.

      a 20v head gives you more moving parts and far more air flow in and out of the motor for more power.

      Quick question i must of missed something.
      I would like to do this i have an ABA obd1 block do i have to use an AEB head or can i use any of the 20v Heads? I know the AEB engines came with an external waterpump apose to the newer model 20V is that the reason why i would need to use the AEB? Besides having better Ports.
      By the way i would be using Standalone.

      are there any other heads that will work?
      All 20V heads will work but only the VW Passat/Audi A4 got the big port heads (Only applies to NA)
      Thanks Wizard [IMG]http://**********************/smile/emthup.gif[/IMG]

      One advantage to the small port head is that you have a greater choice of off the shelf manifolds for cheap and can have the TB on either side
      if that matters
      Also, the small port heads cooling jackets across the rear side of the head (directly behind each Combustion Chanber) are more conducive to the ABA head gasket. You can see what I mean if you page back a few pages to where I modified my AEB. I actually welded up and bridged the cooling jacket gap on my AEB. There are others who run the AEB unmodified though and seem just fine. I am just a stickler.

      i'd assume somebody couldn't just use those cams in a aeb head for a affordable set of N/A cams... that would be far too easy.

      1 crank and you will bend all the valves if you bolted that head to an Inline 4 engine
      Custom cams would have to be made.

      In case someone can't find and ABA pulley and or wants to run the 1.8t, it appears to be a viable option if you create a Hubcentric shim ~6mm. Diameter is the same.
      1.8t transverse in comparison to the corrected ABA.

      Just managed to read almost all topic since the beginning but I've got the mess in my head right now
      I know the answers are all here, I've read them but I just can't put them together (and plus my not perfect english...)
      Ok, thank's to some friends of mine I'm beginning a long 2020 story. I think the first 2020 engine in Ukraine and for the start got just some simple questions. I'm building it from scratch and it;s being put down in the car instead of the 1.4 only after it's completely built.
      The engines I can find here differ from your's as we have european engines (it's easier to find the 4.2 RS4 engine here then an ABA)....
      The basic plan was: The 9A or 2e block repaired to 82.75mm bore, the new 82.75mm 9A pistons cut for the 20V head, the 20V head itself. That's the simple point.
      I have to mention it's kinda difficult to find some "tuning" stuff such as JE pistons etc here - so the idea is using stock VW parts for maximum.
      The first basic questions:
      - What conrods to use? The 9A or the 2e ones as they're different?
      - What crankshaft - 9A or 2e?
      - What CR will I have with that? Will I be able to use turbo? ANd eve more - I'm still not sure about wheather I want forced induction...
      - What head gasket to use - will the 9A one be ok?
      - Will the 9A head bolts be ok?
      - and the thing I just can't put together in my head is the cooling system - I'd like to leave as much stock as possible - is the 9A/2e cooling system (with the heater in the cabin) "connectable" to the 20V head? Just can't remember I saw the answer anywhere..
      - and the last one for the moment - engine management? Which will be easier to install and to connect to the stock Golf's electrics? The 1.8T Motronic or the PG Digifant?
      Eeem... Thanx in advance for your patience....

      The 2E is Europe's ABA.Its a 236mm tall block but with a counterflow head rather than a cross flow head.Both the 2E and the 9A have 82.5mm bore,not 82.75mm so if your using 82.75mm then they are not stock bore.But either way yes it is cheaper to cut 9A pistons for the #5 valve than going with custom JE's.

      1. Use the Connecting rods that macth the block.If you use the 9A block then you have to use 144mm connecting rods.If you use 2E rods then you have to use the 159mm 2E rods.
      2. 2E & 9A are the same 92.8mm crankshaft.The 2E uses a distributor so it has no need for a 60-2 wheel on the crank.
      3. With 9A pistons on 2E connecting rods in a 2E block your looking @ ~ 9:1 CR
      4. Head gasket - 9A or 2E will be fine
      5. No you need 20V head bolts
      6. For cooling yes they are similar,you just need to figure out how your going to cap off the front housing on the 9A head.
      7. PG diffiant is always easier than Motronic.You will need to have either ecu tuned depending on your set up though.

      The point is I won't find the 9A/2e block in perfect condition and the 82.75mm is the first "repair size" and VW produces stock oversized 82.75mm pistons

      Thanx. As ETKA gave two different numbers - yeah they differ the las letter only. So any will fit any block?
      9A crank: 053 105 101H

      Yeah, there are people who can remap either Motronic or Digifant (well, I hope they can remap the old Digi too).
      But what about reliability? What system will be more reliable with that hardware setup as the Golf is my daily-driver? The whole Motronic system or the whole Digi?
      Yeah, Digi is much easier - but wheather will it be more reliable with the 2.0T setup?
      And the final neat touch for the Motronic - the "check engine" lamp in the mk4 gauge panel will be functional in case of something...

      1. 2E = 236mm block,9A = 220mm block
      2. Yes both cranks are interchangeable
      3. As always
      4. 9A piston in 9A block = 9A stock compression ratio = 10.8:1 or there abouts
      5. You need to get head bolts from an AEB.Not from an AWP...
      As for Digi vs Motronic...unless you have a good chip tuner then your best bet is standalone.
      btw I do ship to Ukraine
