how would you know Fit/Doesn't fit???

[somy6]

Well I have a 95 Sc300. I also have a 2006 350Z that i dont own anymore but have some parts left of it. I was wondering how would someone know if these parts from another car fit or not. I have two things that i want to put in the SC.
Front brakes, they are the same lug pattern but how would you know if they fit or not???
440CC injectors, would the injectors fit if i get the right rail or what???

Any help would be really appreciated. Thanks in advance

brakes - doubt it, the bolt pattern on the lower control arm should be different. If you want to prove me wrong, you can take your old assembly off and see if you can fit on the new calipers.

injectors - doubt it as well. even if the impedance is correct, the physical size may be different. Again, you never know until you try it.

FYI, your sc can fit ls400 and supra tt brakes (both 4-pot) and the injectors are high impedance, and are direct fit to few rx-7 (fd) and most rb20det injectors. The ones you'll find that is direct fit is usually 550cc.
