Nissan Top Feed Injs

259cc = 175 WHP * Grey

Side Feed Injs

333 cc = 226 WHP * Grey

Q45 injectors are known ad "Phase I" injectors and are in fact 370cc injectors.

Theyre side feed. Ive used them before. Theyre easier and cheaper to get than the common purple 370s.

Theres been some reported cases of them requiring frequent cleaning and them clogging on occasion, whereas the purple injectors tend to be aot more reliable because of the newer design....

but wither way, the Q45 injectors are 370cc
