You should probably start your own thread, but I do think your premise that you can compensate for greater air flow on an EFI engine by fitting bigger injectors is flawed.Glad I am asking the question now. Listed on Ebay USA refurbished OE 280z injectors 380c..
Wont be buying those then...
However as I am looking to replace, and looking at the same changes..
increased air and exhaust flow, upping the injector size ? Or will the standard injector be able to handle the increased air/exhaust with ease.
I would rather not be running lean.
Genuinely not trying to hijack the thread. Thanks
TBH I suspect a change of air inlet routing and exhaust manifold won't significantly change the amount of air the engine flows and so you should leave the EFI stock.
