Difference in TEIN EDFC motors?

[Persona]

Hey guys just snagged a TEIN EDFC kit at a local shops clearance sale. I noticed on teins site that the motor kit is not the one suggested for my make/model. Is it just due to wire length etc? Or am i out the hole.

Your kit may have different shaft threading. The s13 kit has motors with 2 different shaft threadings. The rears threaded smaller. So you may not be able to mount them on your coilovers.

Damnit thought so, well i guess i'll just have a extra set of motors ha.
