      Does this thread include the BGD? ...im in the beginning research stages of a 2.0 20v, i have a BGD shortblock with 40k, is this good for the 20v head? it has oil squirters and a huge oil pump... compared to the AEG which i didnt see any oil squirters and it had a tiny stock looking oil pump.
      Also are the stock pistons ok to use if i notch them, or are they junk? thanks in advance [IMG]http://**********************/smile/emthup.gif[/IMG]

      ok so has anyone had any problems running notched/clearanced pistons? is it better to notch 9a pistons rather than the stock 2.0l pistons? do we know if the 30v audi pistons will work without modification? ...if so whats the c/r of that setup?

      It's a housing that contains twin balancer shafts aswell as the oil pump. It can be ditched and replaced with a transverse 1.8t oil pump. [IMG]http://**********************/smile/emthup.gif[/IMG]

      what do the balancer shafts do, better to have? will an aeg oil pump work?

      Ros and piston would cost about $1k. Is it really worth trying to notch stock pistons?

      as for the piston problem that has been mentioned in this thread, wouldnt it just be easier to get a set of overbore 1.8t pistons?

      1.8T pistons have an incorrect compression height (wrist pin location). If you threw 82.5mm 1.8T pistons in the pistons would hit the head @ TDC.

      unless perhaps you get some custom rods or custom crank, maybe both just for giggles

      what if you used a head spacer? if you were going turbo.

    16. 10-11-2008 03:45 AM #91
      a head spacer in combonation with oversized 1.8t pistons would be a good idea, If you could keep your compression ratio high enough for the motor to run properly.
      It basicaly works like this, if it takes a .0625 headspacer to clear oversized 1.8t pistons in a 2.0 block, and said headspacer drops compression 1-2 hole points, then you would need piston custom machined to be 1-2 points higher in compression than stock 1.8t pistons.(if you wanted to run the factory 1.8t turbo pressure).
      I could be wrong tho, it might actualy work just fine with just a properly sized head spacer and oversized 1.8t pistons, because essentialy I guess there would be the exact same compression distance between the head and the piston as whats in the 1.8t.
      If someone could identify which one of my ideas are correct, then we might have this problem solved.

      does anyone know what cambelt, tensioner and cam pulley to use on a AEB head on an AQY (mk4 2.0l 8v crossflow) bottom end?

      ok so i started hearing about the 30v v6 pistons do they freaking work or not? i'm building one and everyone seems to still be arguing about it one year later. i know JE makes pistons for this application. jrc has a lot of info, but if i can get a sset of the 30v pistons for half the price that would be even better

      the 30v piston may work but you wont be able to run a big cam or alot of boost

      Any solid answers on the use of the 30v pistons on the AEG 20/20T?

      Just to throw this out there, isn't it just a lot easier to just build a 2.slow out of a 1.8T?
