r34 different model types

Does any one here know what a the different models of the r34 are? Of course everyone is obessed with the GT-R, and everone knows what equipment that has. But what about the GT-V, GT-X, GT-FOUR, GT SPECIAL EDITION, GT-T? I am wondering mostly about the engine specs, and if they have awd or not. I can't find any sites that have this information on them. If anyone has any information I would greatly apperciate it. Thanks.
