with the wet kit you can run it a little rich with the fuel jets. This will give you a little better safety margin. Also if you are running a relatively small shot (60-80) the effects are not as bad as running a 150-200 shot. Like Illusionz said, the Z motor is very strong even the N/A which has the same rods and crank as the TT and you see some of the boost that these guys are running on stock internals. I think some of these boost levels are equivalent to a 100 shot on an N/A as far as wear goes.
