Airflow rates on a 14b? And turboing a LT1 camaro

Ok. So I have a spare 14b turbo laying around. I used it to turbo our 88 dodge dakota 4x4, but eventually got tired of fooling with it and took it off.
Since the 95 LT1 camaro hardly ever gets driven anymore, its the perfect candidate.
My only question is what is the airflow rate on a 14b? Like maxed out, how much air can it push?
I can make the setup and get it working, thats no problem. I'm just wondering if the turbo will be a restriction in my intake.
If im not mistaken a 14b supports around 275ish maxed out on an eclipse? The camaro already has close to 350hp. What do you guys think?

Thanks for the help.

In this case a 14b would take power away rather than add it. A given turbo can only flow X amount of air so if the car is already at an airflow greater than the turbo can supply, I'd imagine the turbo would restrict the motor to its highest flow rate. Regardless, a single 14b is entirely too small for a V8. If you had to turbo it, the smallest I would consider is probably something a shade smaller or equal to a GT35R.

I agree here. The 14b is way too small for an LT1. I would do something about the same size as the gt35r or similar...

Well here is what we are going to do.
Doing a single turbo ran off of 4 cylinders.
My buddy says he seen a guy with the same car running a single t3/t4 and it was making power. Side by side a t3 isnt a whole lot bigger than a 14b.
Which brings me to my original question....how much air can a 14b flow maxed out.

Tim was flowing 27 lbs per minute on his 2.3L with 272 cams at 10 psi. Unless I am mistaken, I believe thats about maxed.

According to an old post by Kevin, the 14b flows all of about 30 lbs/min.

In this case, the real restriction is going to be the turbine housing. It spools very quick on a little 2 liter, on a V8 it's just plain wasteful. The name t3/t4 itself can be misleading, there are some decent sized t3 turbine housings and wheels.
