I got a cheap TT drivetrain conversion (subframe, TC, transmission, etc. from a 92 RT/TT ) and I'm also planing to upgrade the brakes to the 1G TT, the rear end (subframe) already have the TT parts, for the front ones I'm aware that I need to replace the knuckle, hub, rotor, caliper, tie rods? If I wanted to preserve the ABS, I would need to replace the sensor/ring on the fronts, then it should plug-in into the existing ABS wiring right?

Also, the TT ABS pump, ABS computer are different, I've checked ASA and the service manual, those have differences in its output (TT pump), someone has done this, TT brake upgrade WITH the ABS?

I have (94 SL):
ABS computer: MB686562
ABS pump: MB668391


For a 92 TT/VR4:
ABS computer: MB686563
ABS pump: MB668392

Your na ABS will work fine with the tt parts. And you won't need tie rods, just the tie rod ends at the hubs.

Oh, great thanks, I noticed on the wiring diagrams that the NA ABS is more complex but the TT one have an ABS signal wire going to the ECU.

Well, another question, I got the TT Rear subframe (from a 92 TT with 1G brakes), I have a 94 (2G MTX FWD) can I just swap the rear end with the attached brake lines or I need some combination with 2G FWD Inner lines + 1G TT outer lines?
