Dear members.

I own mazda BPT (GTX) and will upgrade the turbo soon.big 1.
My problem is i want to change injector to the bigger cc.
First choice in my mind is VR4 (450cc) or EVO injector (550).
SO i heard ppl say that our BPT injector impedance is high and
VR4 or EVO is high.So how to do if i still want to use this kind of
injector? i need to add a resistor to the injector??

VR4 injector is plug and play at engine? no need modification?
How about socket? same male and female socket??
SO if someone had try this before, pls guide me...

Thanks.
