I've been working on my '87 FI RX7 for over a month now, filtering out all these minor problems and have blown a descent wad in the process. . . this car has great potential and I refuse to give up. . I need a radiator and all my problems should be solved, does anyone know where I can find parts for cheap but are reliable online?

 

Do you want new or used?

USED: try http://www.car-part.com/

New quite a few places so then do you want stock or performance parts.

Stock: try http://www.blackdragonauto.com/index.htm

And then for performance. Many to take your pick from.

And of course there are the parts for sale threads right here.
