injectors

[Boostdeznuts]

I have a 67 Chevelle with 5.7 stock moror with 4L60E tranny. Am putting in a 76 turbo on it . What injectors should I get to run that turbo setup ?

A set of 80# Siemens should do the job........[Unless you are on E85.]
80's at 4 bar are now 94#. [What I'm starting with on my 5.3.]

You have any extra 80s laying around Chuck? 8 I need lol

Would you need adapters with the Siemens 80 for the ls stock harness?

i run 60s which if you put alot of boost down its throat youll make them out super quick.

If it's an LS1 harness, then no. If it's a truck, then yes.
We just cut the truck connectors off, and crimp the EV1's on. FAST has a kit w/ the pins, connector bodies, etc. That cleans it up, and eliminates another connection.

For an OEM app, we use EFILIVE.

Sorry, I don't. I snagged these on LS1tech. He was going to E85, and was selling his 80's. Super deal. Near new, $200, shipped.

Whatever you do....Be really leary of any of the lo buck injs on the bag!
I've had some come here for "issues".. Ended up in the trash.

Thank you I just finished installing a 4.8 4l80e it's up and running n/a now but was thinking of turbo set up ... How difficult is it to tune with efi live? Would like 500-550 rwp

The learning curve is fairly steep w/ either EFILIVE, or HP Tuners.
You can try the EFI program @ www.efilive.com, and d/l the tuning software. It'll be a demo deal. If you want to buy a suite, let me know.
Are you running the engine w/o a filter?
If so, it'll be difficult to tune w/ the hot air from the rad being blown into the maf sensor.
