hi i was told that you were looking for a SRde swap for you 510. I have an Autech S15 N/A SR20DE/S14 5 Speed set that I am thinking of selling so I can get a DET motor set. It currently has ruffly 22K on it now and is still sittin in my S13. The only issue we are having right now is it needs the right MAF wish i have ordered and should be arriving shortly. If you are interested hit me up.

note*I am currently still deployed for a nother few months but my mechanic might be able to get it pulled and shipped for you. Thanks
