well i blew up my USDM sr20 lowport so i called up soshin for a motor well i got it today and im pissed it is a roller rocker motor with a black valve cover. Which motor do i have from what i have searched it seems to be a newer primera gt 10:1 compression motor someone help me and and tell me what motor i got i already know i cant use it cause my s4s and my ecu thats already tuned wont match up so i know im screwed but i need to know which motor i got so i can sell it or send it back to them also the the head code is 53j 4r
