mucho thanks for the info guys, the reason I was asking about the protoge' was, I found a rebuilt head on line that stated 1.6 motor out of a mazda protoge', I am asking for more info. It was proffesionally done but not installed. Oh by the way, the reason for the lack of power in the XR2 was one of the f#**^ing injectors power source was hanging off the motor, lost the keeper piece, luckily my Beamer buddy found it and had a keeper on hand!! I always immediately think the worst. I will compression chck the motor! Probobly nothing even wrong with it! I just want to be secure before the boost. Thinkin' bout
BOOSTED
for a license plate!
