Thanks guys. All awesome info. Now the dilemma I am having is.
I have the GX in the car running fine and a complete 96 2.0 gti in the garage that needs a head gasket.
If anyone feels like throwing in their preference and experiences it would be great.
A. Change pistons and get larger valve head?
B. ABA bottom with larger valve head and stay CIS?
C. Swap the whole ABA over?
Its a daily that goes to the track once a month or so.
I have been into VWs and racing for years but always on the suspension end of things.
This is my first "built" I use the term loosly engine. So my apologies if I am asking a bunch of dumb questions.
It seems that all I hear around the vortex is ABA stuff but over at clubgti.com many of the purpose built cars are still building 1.8s
My last autocrosser was an 87 golf gt. with TT header, TT cat back, 268 cam, Eurospec cam gear. Cam timing was retarded 3 degrees if I remember right. The car was a blast and won two seasons in a row until they put the Suzuki swifts and Datson 510s in the class.
