jspec s5? no flames
 

im gon get a jspec s5 and i have usdm harness and ecu. would that just bolt in and conect and run good? i know the s5 has lighter rotor and comp thats y i wanna kno. thanx

Just bolts into a S5 Turbo car, yes... it does.

make sure the harness is from a S5 TII and you'll be set. other wise you'll have to mod your harness

you will also need the manifold and throttle body from the us turbo motor. j-spec tps has a different plug and some vacuums on the us manifold are needed that the j-spec doesnt have

no... you do not need the TB from a us motor. i used an USDM harness on a JSPEC motor with no problems.
