Almost 100 views and not a comment??? I know someone has some sort of input
Picking up a parts car with a friend and it just so happens to have a g60 block with a callawy kit on it. The past owner has it running on the digi 2 system. Now what am i getting myself into with this. Mind you im grabbing this just for the callaway setup but im trying to see if using the g bottom end is worth using. Any info would be dope, i know extremely little about the g60.
Most of the hard core S/C guys will tell you that the extremely heavy G60 internals won't work all that well with a turbo. There is some truth to this. But..... the real key IMO is engine management. DIGI 2 is entirely unsuitable for ANY forced induction. DIGI 1 with a G60 turbo specific chip works but Standalone EMS will really make it rip.

G60 internals aren't really that heavy compared to any other VW engine. The PG bottom end is indeed very stout, head flow is always more the issue when gong for big power. And that doesn't matter if its croosflow or counter flow.
DIGI 2 is about the worst management for running a turbo on, I would say CIS is worse, but you would certainly have better success with CIS running a Volvo or other fuel distributor.
DIGI 1 would be better, but a stand alone like 034 or Mega Squirt will net the best results. For the kinda of power likely to make with a Callaway kit, Digi 1 with a stock chip would probably suit your needs. I don't imagine the callaway turbo made much more then 10psi on an 8v?
I wouldn't try to turn this into a power car anyways, I would try to maintain the integrity of the Callaway kit and restoring the function of something rare and very cool.
But the single most important thing I can stress here is this: Please, PLEASE! sell me the Callaway Valve cover!
