I put a silvertop in my ae92 when the bigport died and was disappointed to basically end up with the same performance (maybe powerband shifted higher slightly?)
Now its got a blacktop ecu/loom and it does go better definitely. Hopefully even better with the blacktop head/manifolds down the track - we'll see.
Honestly i dont really think there is a "better"
If the silvertop goes no better than a 16v, but the blacktop isnt as tough, its 6 to one, half dozen the other.
