Mounts:
Engine Mounts for Codes ATW/AEB/external waterpump blocks:
-OE Mk1 engine mounts will bolt to these blocks, you do not need custom mounts.
Engine Mount for Codes AWD/AWW/AWP/all internal waterpump blocks:
-You'll need custom mounts for the engine
Trans Mount for O20:
-020 trans bolts right in with OE mounts
Trans Mounts for O2A,O2J:
-You will need custom mounts for these transmissions

Who Makes Custom Engine/Trans Mounts??
-WRDUSA.com sells a O2J mount kit
-Vortex user need_a_vr6 can sells O2A and O2J mounts
-Vortex user Pataron can sells O2A mounts
-Dan Bubb <jdbubb@verizon.net> sells O2J mounts
-I(boostin20v) have one set of custom mk1 frame rails modded for mk4 mounts, PM for details

Wiring Diagrams:
AEB Diagram

Which 20v engine should you use?
Engine code AEB from the 97-99 Audi A4 and VW Passat.
Benifits:
-use of Mk1 motor mounts, no need for custom mounts
-larger intake and exahust ports:
-big intake ports: 54mm x 26mm (small ports: 43mm x 26mm)
-big exhaust ports: 36mm (small ports: 33mm)
-20mm wrist-pins (later engines have 19mm)
Cons:
-AEB engines are hard to find, and the euro versions (AGU/ADR) are difficult to find/import

Forged Internals?
AEB are all cast
AUG auto is cast, AUG manual is forged
AWD/AWW/AWP/AWM are all forged

[general problem]

slow day at work Stu??

[Boostin20v]

vortex should be my work

[vdubspeed]

this is better than the official 16V thread by 4 valves!

[polov8]

Thanks for putting a link to my thread in

I really will try to get the thing fired up before Christmas

[Boostin20v]

added Talx's swap

[.:Carlik:.]

this is great

[Boostin20v]

anyone who uses this info for a project, start a thread dedicated to it and I'll add it to the list

[Todesengel.]

seriously, this needs to be sticky!!

[diabolical1]

i agree ... should be a sticky!

[.:Carlik:.]

anybody want to give help on wiring to ce2 ? using AEB harness that is !

[G60 CAB]

So the hot setup is an AEB block with AWP internals?

[Boostin20v]

nah, keep the whole AEB. The later blocks have smaller wrist pins (19 vs 20mm)

[G60 CAB]

But can the cast internals keep up with big turbo setups?

[Boostin20v]

the AEB uses an external water pump, an intermediate shaft....its very much like an older 8v or 16v. the newer engines are internal water pumps without the intermediate shaft.

[Boostin20v]

bump as....well I dont know seems people cant find this

[Boostin20v]

added AEB wiring diagram -- thanks [inser username of person I forgot]

[.:Carlik:.]

LOL it was I

haha sorry bout that, thanks

[vdubspeed]

I was checking out funksoulkitty's webpage and now I have a question.

If I use an AEB motor from a passat and have to switch to a golf/jetta intake manifold. What year should I use.

Thanks.

AWP vs. AEB

[donmeister]

sweet thread, good job

I made 319whp on a dynodynamic with my OE AWD small port intake manifold on my ADR (euro equiv AEB) head. Car was running a Tec3 with a ok, not great tune. bascially my point is that you can run a small port intake manifold without too much problems (FWIW 319whp on the dynodynamic is somewhere between 360-370whp on a dynojet).

Ideally you've got two options.
Option one you'd buy a AGU intake manifold, the AGU is the only transversely mounted large port engine code. Problem is it was a non US only setup. From time to time they are avaliable on ebay.de and even the vortex classifieds.
Option two you buy an aftermarket intake manifold (~$525-~$1000) whcih you can order with TB on either drivers or passenger side and either small or large port.

360whp! hopefully someday my golf will reach that

[RiegerGTB1.8t]

wow

doh, looks like I fuged the permissions on the file. I'll get it working tomorrow.

[vdubspeed]

New question:
If I have use an AEB ECU...will I still be able to check the codes using a OBDII port and VAG-COM?

If you can't pull the codes...how will you know what's up with the motor?

[Boostin20v]

if your going to use the AEB ecu then make sure you wiring in the OBDII port. without hte port you wont get the codes.

perfect. I'm assuming it's only a couple pins anyway to get the codes. I'd love to see that AEB wiring diagram if you get the .pdf back up.

[Boostin20v]

I swear it'll be up tomorrow!

Its only 3 wires to wire up the scan port. power ground, and the harness k-wire (grey/white)

the bewildered looks you get from people as you plug in your laptop to and ancient ass rabbit. always a good time.

thanks...I was sure it was going to be about 3 wires.

[oopseyesharted]

any idea where i can get info on getting a 20v head on my aba block???
I want to run NA.
