550cc injectors w/out tune? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

My friend needs to borrow my stock injectors.

I have some 550 injectors that I just got but was waiting on enthalpy tune before putting them in.

I have fuel regulator.

Question is:

Can I run the 550cc injectors, adjust the regulator so that it's running stock pressure and be okay for a while?

What kind of harm will that do to the engine?

Don't you'll flood your plugs.

None... If it even starts/stays running. If it does, it will likely run like shit for a while, then flood out.

My advice is to tell your friend to wait till your Enthalpy ECU gets to you.

nah, you're good. put em in. you got this bro.

and put a bunsen burner behind your exhaust tip on start-up.
