Stage ! in!!!
It'* been a while. I got the stage 1 kit [under drive pulleys ported and polished throttle body,1/8 rockers, fan switch, 180 thermostat']. I also put in new upper intake gaskets,plugs,and had the coolant system flushed abd refilled because I had mixed the coolants due to the leak in the intake gasket. All I can say is wow! Horsepower gain has got to be 20 to 30. Nail it from a standing start and the tires burn until the 1-2 shift. Kick down into passing gear is just awesum. The down side is a loss of about 3-4 mpg and a rough idle at start, and the temp runs 195 to 200 even though i put in the 180 degree thermostat. Which makes the next mod of a trans cooler move up the list. Anybody with a N/A 3800 should pony up and make these mods. My wife will even drive my Bonnie now and her car is a Trans-Am!
