im just wondering if this swap is just as easy as the red top sr20,  
is there any wiring issues or anything that i should know , witch would make the swap harder then usual ?

I was thinking of doing the same swap in a little while and I was just about to ask the same question.

Are you referring to the blacktop S14SR20DET motor? If so, yes the wiring is different and more difficult. If you send your harness out to be modified then it really is not that hard.

yeah, but for the extra money an S14 SR costs you could put an SAFC2, injectors and turbo upgrade on a S13 SR (just not a $1200+ brand new garrett, used T28, something like that)

or S15, the valve cover isn’t flat like S13… due to VVT
