#2852, "Are 4g63 injectors and 420A injectors the same shape?"
i know they don't run off our ECU, which doesn't concern me since i have a stand alone waiting to be installed, but i was wondering if i can use stock GST injectors for now to get this thing up and running? I just need to know if anyone has compared them side by side to see if they will fit our fuel rail and injector bosses on the manifold? If anyone has compared the two, let me know, or else i'll have to pull mine and check.

you must not have read what i wrote...i already understand that they are different in regards to peak and hold and saturated. i have a haltech E6K that i purchased...and i am looking to get it up and running for now...until i get all the bugs out i don't plan on running insane boost levels. All i was wondering though was if they are the same in regards to fitting into the fuel rail and injector bosses.

Can you guys explain the diff. between peak and hold and saturated. I'm getting my star stage 1 in a week or so and plan to install my bro's 450cc injectors off of his galant vr4.

Cant answer either question except to say the Galant uses the same injectors as the turbo talons and wont work on our car even if they do fit the rail (I understand Jason has a Haltec that can work with either type, this isn't directed toward you so dont snap at me).

Looks like no one, understood your question! Well I hope I have!
( I am about 90% sure ) From a quick look that I took last time, YES it does look like they will fit to our fuel rail. Our fuel rail will take just about any "bosch type, O-ring" fuel injector. However the actual wiring clips for the harness may be different (but I am assuming that you are hard-wiring the injectors directly to the Haltech.
I am glad that there are memebers like you willing to take our mods one-step further. The Haltech is my next mod, after my car is running again (I am currently going through a $$$$ major engine modifying spree - port (& flow), polish, balance, bore, 3-angle valve job, SS valves, titanium retainers, etc..)
Good luck!
