Im about to buy my first FD RX7. Im looking for some vendors to get aftermarket parts from ... not for high performance but more for reliability mods such as an upgraded radiator, hoses, vacuum lines, intake ... small stuff. Also, does anyone have any experience with lithium-ion batteries? I did some research on bike batteries and the weight difference from lead-acid is huge ... around 9lbs to 2 lbs for comparable performance. If I could get a list of some companies to check out I'd really appreciate it, thanks guys.

 

check out Mishimoto..They make great radiators.

 

Also Koyo however there a bit more expensive.
