dont do SR unless you have $6000 that you dotn really need for anything else.
you can do it cheaper by swapping goodies from a clip over but a stock SR for $3500 will have you wondering why you spent $3500 for less torque that your KA down low and not a whole bunch more top end.
another $2500 in FMIC, full 3" exhaust and sme other minor mods will reinforce why people do this swap.
KA-T is ghey unless you are doing ALL OF IT YOURSELF, and HAVE ALOT OF EXPERIENCE or RESOURCES at your disposal.
you dont simply slap bolt a flange and a turbo on your manifold and drive away with a KA-T i’m sorry.
Chris (Canadiandrifter240sx) can do SR or KA swaps as well as anyone and is usually cheaper (if you have all the parts already)
if you need parts, myself, varun and andrew can hook u up with everything you need.
