Cobalt SS injectors

[Azrael]

I have access to a few injectors from a supercharged cobalt for pretty cheap. They're 32lbs/hr and was wondering if anyone would know if they'd fit Gen3 manifolds/fuel rails?

WAYYY too big for a N/A 3100. I've got 24# in my car and it runs extremely rich even with a low base fuel pressure. Unless of course you tune the ECM for them.

If they fit you should sell me 6 of them for a good price

got any pics?

i have a set of Multech 1 #24's that i'd be willing to trade or Multech 2 #22's if that's what your harness is for.

I'm going supercharged later in the year so #24 won't be enough. I don't like the idea of tuning with an RRFPR thrown into the mix so I have to look in the #30-40 range. When I say local, what I meant was the next nearest city so I don't have direct access to them to be able to take pics.

they "SHOULD" fit physically

however, you should check the height of them installed and if they are sitting in the manifold properly. i helped my friend change his 00+ 2.4L injectors to stock ion redline (supercharged 2.0L) injectors and we had to clearance the rail a bit, to allow the fuel rail to move down a bit (1/4" if that) becase of the shorter injectors.

then i grabbed his 2.4L injectors

L67 injectors are what most people go with when boosting these engines, they are #36 and fit perfect.

How do they fit with the 3x00 fuel rails?

I would assume Perfect since thats what he said...

Yep, they're the same as the stock 3400 injectors in size.. just white plastic instead of black.

I wonder how those ^ will react with OBD1 (not 1.5) and boost?

[Azrael]

The L67 injectors were also on my list and I'll probably go with them since they'd just slip right in and are also in big supply. I was just curious if anyone knew if the 2.0SC ones would work as well. I guess GM used shorter injectors in a lot of their new engines then.

you'll have to spend alot of time tuning but they should work fine. I was running #22 Multech 2's on OBD1 last year w/o problems.

I guess I should just go with the known L67 injectors then.

Thats what I'm running now...

What O2 MV levels were you getting and what injector PW readings were you seeing?

Or did you not go that far into tuning?

If i can find my datalogs i'll have a look. I know it was running lean, BLM's were in the 130's but i hadn't added more fuel after i ported the top end and put on the headers..
