Turbo/Non Turbo 4G63 Ext. Differences?

[Attrayant]

Hey all,
I was wondering, is it possible for someone to use a nonturbo block, turbo head, and still retain the turbocharger with minimal problems? Reason why I'm asking is a friend is thinking of buying a 91 talon tsi awd but he was afraid that the previous owner might have swapped out the turbo block with a non-turbo block off of a junkyard or something. Is that possible? Also is there a way to tell by lookng at the engine, as it sits in the car, if the block is out of a turbo or not?

Bump - anyone?

im pretty sure if he was using a non turbo block the compression ratio would be all messed up, and it couldnt handle nearly as much boost.


not too sure how to tell or not, but why do u think the owner would do something like that ne ways?

Because the guy who sold him the car had abunch of 4G63 non-turbo's laying around and he thought maybe the guy would want to keep and build the turbo block and just throw the non-turbo block on his and sell it that way, trying to be sneaky. You never know these days.
