20v head + MK4 2.0L AEG, AZG, and newer (NOT ABA, NOT 9A, NOT G60, etc)

[redline_etc]

There is water menthol injection that will keep the piston temps down if you plan on big hp numbers

[vwknight]

instead of replacing or notching the pistons, couldn't the right size headspacer keep the valve from smacking the piston?

Ehh, compression would be too low I believe

[VwBoy2.0L]

Do they have any AVH blocks?

[vdub_jeep_club]

Has anyone successfully done this yet? NA at least?

I still need more info on this.
iv been reading and preparing to build this for about a year.
I need to know what parts are needed.
on hand i have
2002 awp gti donor car, the block is unsuable.
i have an AEB head in my basement and a AEG block and Crank.

I would like to use the AEB head and find a AVH block with Oil squirters.
-
as for the parts list i think i need but know im missing some stuff.
Eurospec 83mm 5v pistons
forged rods (144mm, 20mm)
European head gasket
1.8t timing belt kit
-
id also need to shave down the 4th oil squiter
then everything else from a stock 1.8t gets swapped over ?


could Richard_Cranium or mk4_2.ho chime in i belive you are buildin gor have built them ?

[bonesaw]

you need pistons for 92.8mm crank and 144mm rods. Thats about it. you can swap the 06X oil filter flange over, etc. depending on piston size will depend on gasket you use. I did not have to modify any squirters for my AVH block.

[1999.5GTIVR6]

Perfect, thanks for the information.

just have to decide if i want to use the aeg crank or swap to a TDI crank. then ill be ordering a parts list

[bonesaw]

If you use tdi crank you will need different pistons.

[1999.5GTIVR6]

doing custom pistons anyways

[ayrdesigns74]

I have a APK block setup with a AGU big port head turbo manifold ko3 turbo custom piping running with Megasquirt 2 it revs to 7000 rpm easy it needs tuning some more but it runs except for the clutch slipping a bit, I took out the pistons got them notch for the fifth valve ,realy nice set of MAHLE pistons by the way used a 2.0l head gasket i got from Germanautoparts.com 1.8t heat bolts and rod bolts

ayrdesigns.......i just creamed my pants, your ride is gonna be a beast. get a build thread going man, a lot of peeps will follow it. good luck with the build

[1999.5GTIVR6]

so whats a better base.

AWP block bored out with a 2L crank.
or
AZG/AVH block.

is the bored out 1.8t going to face over heating issues while idling in traffic.
physically when it comes to size are the blocks different ?

[elRey]

six of one, half a dozen of the other

[bonesaw]

The benefit to the 2L block is you will have a 92.8mm crank already. The block is also beefier. All the 1.8t accessories will bolt on. The only downside I can see is the coolant port on back of head isn't tapped.

[elRey]

The block is also beefier.

They're from the same casting. So, this is not true.

The only downside I can see is the coolant port on back of head isn't drilled/tapped.

Small addition.

[bonesaw]

Less boring. Haha. It really doesn't matter

[1999.5GTIVR6]

They're from the same casting.

how did you find out they are from the same casting?

iv looked at both and feel the 2l in fact beefier.

I have an awp block on my back step and an aeg in my basement i could pull out and compare

Please do and document where you think one is beefier than the other. Then come back and share your findings.

If you have a aeg, why don't you use it? Just for the oil squirter thing? remove the 4 halen bolt that fill the hole, and screw your 4 oil quirter, plug and play.

As for the head gasket, anyone ever took a look at a 2.0 fsi head gasket and compare it ?
