JDM parts?
 

so i have a USDM engine and someone is offering me a deal on a bunch of turbo ii s5 jdm parts such as LIM UIM and throttlebody,(i already figured out the difference between USDM and JDM on these), my question is will JDM s5 tii fuel rails, and injectors work fine, i imagine they would, i just wana make sure that im not gonna buy parts that will be useless to me. i plan on running a n370 ecu with an rtek 1.7 or 1.8, i wana makesure the fuel system will work fine with the n370 ecu too. i imagine it would but again, just wana MAKE SURE

fuel flows through JDM fuel rails the opposite way of USDM (FPR on primary, PD on secondary)

They'll work fine, just have to hook p the lines differently like mentioned above. I must ask why you want them though, is something wrong with your current rails and injectors? There's no performance difference between USDM and JDM, your money is best spent elsewhere (unless you really need to replace your current ones).

haha i thought we was being a smart ass with the fuel flows oppisite ways thing..but i guess it does. the only thing wrong with my fuel rails is that they are NA fuel rails and NA injectors, (im building a turbo engine) and im buying this stuff for a good deal from a guy who ordered a j spec engine.
