I Just Bought This 93 rx7 And Was Told To Put An Aluminum Radiator And Change The Vacuum Hoses To Silicone. Does Anyone Know The Size Vacuum Hose I Should Use And Where To Buy Them? Thanks For Any Info.

 

First, go to the Main Section under 3rd Gens and the first few "sticky" posts has most if not all of your questions answered about your new car (congrats by the way).

Second, you can buy a kit with all of the required hoses and tools as well. I just bought mine from hosetechniques.com. I think around $120.

Good luck!
