    Need a quick aba 16vT question answered

    Anyone know what the CR is going to be if I slap a 16v head on an ABA? The internets are not being very helpful. I blew the engine up in my vanagon last week two days after replacing the transmission I blew up.

    So I figured more power is order, logically..

    ugh.., I remember talking about compression ratios for exactly this years ago.. don't remember now. It was something like 9:1 iirc, but I know that's not a helpful answer

    Damnit! I suck for not following up. Its 8:1. got it sorted. parts on the way.

    that's quite the drop in compression. Isn't an aba with a counterflow 1.8 head going to run at around 10:1?

    Maybe I'm just forgetting numbers like usual...

    Yeah, that sounds about right. Might even be closer to 10.5:1. Need more area for extra valves. Think about the 16 piston crown that is flat with relief cuts just for the intake valves. Drop in compression means room for boost

    I used to want to switch to an aba-16vT on the gti. That combo makes good sounds

    8.5:1 or so is what I remember. It'll probably run like the old Porsche 930 turbos. Absolute dog until the OMG TURBO!!!

    And from what I hear from the G60 Corrado guys, the OBD1 ABAs are the ones to have. Oil squirters, forged internals and such. But of course this you probably already know.
