Base to Type S upper intake 03 TL

Hi, I'm about to install a type-S upper intake manifold on my base TL, I shop also for the type-S ECU, maybe bigger cc injectors along with fuel rail and fuel pump, I've already got AEM CAI which I know I'll have to cut a couple inch to fit the bigger(longer) throttle body, also equipped with DC headers...

But my question is: do I have to change more things, I fear I would be short of connectors for this new piece... and if I keep my fuel system as is, would it be enough ?

If Somebody already done this Mod, I would appreciate some advices on that job ;-)

Thanks:thumbsup:
