I need some new injectors.  I was wondering if anyone knew what the injectors are rated at in these cars and what might be a good swap.  Maybe a little bit bigger injector to help out when I start putting a little more boost to this thing. :wink:

I think Jeff M. is making a chip to work with the sy/ty injectors which I believe are 29 lb/hr. At least that is what I've heard. Anybody know for sure?

They are 22lb hr. Don't know of any good substitues. New injectors will really make it run right though.

You need to use ACDelco part #17086651... Jeff M has the best price on these, If you can't reach him by email jeffm@turbograndprix.com  cc it to me at jim@turbograndprix.com and I'll make sure he gets it. :)

Is that the original part or something slightly better?  Does anybody know of another vehicle that used these injectors?

That is the Original part #
Everyone that uses different (aftermarket) injectors has problems, Jeff is working on a chip that uses the Sys/Ty injectors, but it is Not ready yet, so if it was me I would either get a set of originals, or just get 2 to replace my bad ones and wait untill jeff gets the chip done for the 22lb injectors (which also needs a set of jeff m ported and polished heads to work with the new chip) :shock:

So nobody has tried the Accel style fuel injectors? I figured there would be at least one person who'd try the far superior design. I dont know if they are compatible with the TGP, but they make them for the LT1s and other GM V8 multi ports.

Well...I haven't tried them yet, but they are on back order and should be here in about a month...I'll let you know how it turns out.

Yes please do so.. I have to replace mine soon in this engine... I would like to know how they work..  KCP

I put the new Accel injectors in my car this weekend...It runs better than it ever has.  I put the 24lb/hr injectors in it.  I don't know if that was all that great of a decision...but I haven't seen anything negative come out of it yet.  My car never idled well and now it runs like a clock.  I couldn't be happier.
I was almost ready to put a brick on the accelerator and let the car sail off of a cliff...but now I am just as happy as a little kid with a new puppy.
Time for an aircleaner upgrade.
What would be the best aircleaner?  Doesn't a cold air intake get a lot of water and dirt off of the road?  I wanted to put a true cold air intake on it but I drive this car a lot and I don't want to be sucking water and dirt up into my air cleaner all the time.

By the way...the injectors are only $180 for six from Summit racing.  Summit part number ACC-150624.  If you want smaller or bigger injectors, the last two numbers are the lb/hr rating, and the 6 is the number of injectors.  I actually ended up ordering 6 150124's because the six pack had to be back ordered.

Glad to hear it's running Mark! I'd go with a K&N directly on the turbo. If you do a search you'll find a couple different part numbers. I have the RU-1390. I'm going to get another one that is an 1" shorter. This one rests against the intercooler.

Any word as to how long the chip will take for the bigger injectors?  I'm thinking of a chip soon...

Mark,

    Glad to hear they worked well for you.  Keep us posted as to how they work long term.  Did you already have a chip in your car?

No...I'm still running the factory chip...Do the chips change the shift points...because my car likes to stay near that red line for a while before it shifts.  It would be nice if it shifted a little earlier.

Dont think it changes the shift points, just chipped my STE and it wants to cut boost under WOT at the shift points.  Did an idle re-learn (again) and will wait about a week to see what it does now.
