I got the S13/S14/S15 special isssue, my favorite issue by far, and it made me want to do a SR swap into my S13 coupe...but i don't know where would be a good place to look for a good one. I've heard of some places but at the same time i hear bad things about those places. so i'm just asking where's the best place to get a nissan engine? plz&thankyou.
