Does anyone have teh GM part number, flow ratings, and original manufacturer for the OEM injectors in a '91 191 CID V-6?

Beyond that, anyone know where I can get a used-but-nice set? (That would just be the icing on the cake.)

 

I don't have the part # or flow rating. But I do know that the 3.1s received Multec injectors.

For a good set, I would send a used boneyard set to Rich Jensen at cruzinperformance.com so he could clean and flow test them.

 

The 2.8l & 3.1l (191cid) have 15#/hr injectors.

The 3.4l have 19#/hr injectors.

As mentioned by MDv6man the 3.1's are GM Multec's.

Can't help with the part number.

I thought that the 3.4l came with 17's??

(160x.50) / (6x.80) = 16.66

You best bet would be a pull-a-part yard, and then send them off to be cleaned professionaly.

Trust me, you dont want to buy from the dealer or any parts place. 45-70 bux an injector. You can buy a used set, have them cleaned and tested, and have better then new.

 

I got a set of 19Lbers on ebay, $50, and sent to Cruzin for cleaning $60 runs like a champ.

 

I've got a set in my garage, yanked from a '90 3.1L, I assume they'd be the same part #. I'll go take a peek at 'em tonight, and let you know. Got them, and the fuel rail they're in, for $10 from a wrecking yard.

 

Thanks for the replies. They definitely are Multecs by their shape. I just haven't been able to pull them out to get a number. I'd like to have a spare set on hand to send to Cruzin' Performance before I jump in head first. I won't even mess with injectors without having Rich check them out first. To me, it's a no-brainer (which is just my speed) any time you pull injectors. They are probably more important than having clean spark plugs, and I won't hesitate to send them in just because they're out.

I just wish I lived a little closer so I could walk them over there. Besides, I'd like to see his shop.

Tom,

I was thinking of getting some bone-yard injectors and sending them in, but I wanted to verify the compatibility first.

 

Vader,
Nice to see you over in this part of the site. Just curious....what are you planning on using these for?

 

hey guys, is it possible to use the 3.4L injectors on a 2.8L engine? I figured if the engine has enough cam and head flow, the extra injector flow would help performance. And, yes, i realize the need for a custom chip. Will the 3.4 injectors fit on the 2.8L fuel rail?

 

They should swap. I have tryed 97 dodge injectors, and 97 ford injectors in a 3.1l fuel rail, and It looks the same as the 2.8l rail. The 3.4l rail looks a little diff up top, but they all should interchange.

 

A '91 Camaro SC with the 3.1 V-6. Stock Multecs are getting too low on resistance and won't always fire. Probably the solenoid insulation dissolving issue again.
