  • hey i got a 95 talon esi with a blown 420a and 2 4g63 NA engine from some 90-93 talon esi's and i want to swap the blown 420a for a 4g63... what kind of stuff will i need? will i need all do the stuff from the old talon like the axles,transmission,exhaust, and computer?

  • @94VDUBgolf That generation of 4g63 won't do it. The only thing worth swapping in that year (because the pre-95 stuff doesn't fit) is an EVO 8 drivetrain. You'd need the WHOLE front clip minus the body. ECU, driveshaft, rear, etc. 1g 4g63s won't fit that car.

  • I have an odd question. Could cramshafts bend on the 2.0 turbo, NT and 18 motors. My brother talking me out from buying a clean unmodified , un beat 92 TSi. Previous owner is an honest guy and told he it has the required maintence done , recently had tune up. Is this true, I told he was full of it and mentioned only the valves get bent not the cams.

  • cams don't bend. If one of the journals seize, they break. Valves bend because they're the thinnest, weakest link in the valvetrain, but that only happens if the engine jumps time or the timing belt breaks. All 3 of those motors are "interference motors" which means the valves and pistons share space at different points in the engine's rotation.

    If that car has had its scheduled maintenance performed correctly, you shouldn't have any problems with it. 4g63's are tough motors.

  • aphex twins?

  • Si.

  • @Jafromobile what mix of window licker is that?

  • @Jafromobile ok thanks im sellin both of the 4g63's im just going to put a crappy 420a in it.

  • @Jafromobile I have a 94 4g63 block just like this.. I blew my oil cap off and my timing belt broke, so as the valves as the mechanic said. Is it still work fixing or rebuilding or just swap it.

  • Oh, there's this comment. I just uploaded both removal and installation videos for doing this with the engine in the car. Process is basically the same for a TD05 series.

    Going from a 14b to a 16g is like going from a T25 to a T28 on a 2g. Everything lines up like it was.
