Turbo vs Non-Turbo 4G63 Head help

[johnnytsi]

Is there any difference between the Turbo and Non-Turbo head on a 4G63?? The CAPS program lists different part numbers, however, I have one of each, and they sure look like the same part! The same for valves, The set of brand new valves I purchased from Mitsu for a non-turbo have the letters 6T on the Valve face?? The NT head I have is in much better shape than the Turbo head, if they are the same part I'll use it on my Turbo Engine.

I just got a non-turbo head installed on my car the only thing differnt is the cams. If its a 90 head the coolant passages and a little smaller.

Do the Turbo Heads use a Soild Lifter or Hydrolic?

Good News for me, this appears to be a newer head, the two end Exhaust Manifold studs are bigger.
