S4 vs S5
Most people try for S5, overall newer, more power, a lot of people prefer the taillights, etc. The S4 are usually easier to find and cheaper. Also the S4 have a mechanical OMP so it can't fail...or you could just remove it and premix.
if u like the s5 look go wit the s4 convert the tailights and the rubber moldings after that you should be good then start wit the s5 swap cause those blocks are stonger why i saw go wit s4 its a bit lighter try to get s4 t2 cause that has everything you need for the full effect wit the vented brakes and wut not and that very sexy hood
