Distributor-----------Check- Si
Alternator/Pulley-----Check - Si

Cooling Fan Switch---I'm using old thermostat housing do I need to go Junking for a diff one? I already purchased a new thermostat to be safe

MAP Sensor----------Same deal, its the old throttle body... where should I do this connection at? Or can I keep it where it was?

Will any of this affect my performance?
