I built 4 gen4's with blown honda 3.5 First cars still own, number 18 and 19 both "Al B." blower kit. The red one won first place at Sacramento Autorama. Second two 2006 numbers 118 and 119 .,#118 "Al B" Turbo KIt and built engine. #119 "Al B." Blower kit. What a coincidence but true. It kind of tells you how many gen4's in two years Funco built.
