d16y8 intake manifold.
what are the power limitations. Can it support 400 +
if not, why ?

I am sure it possibly could BUT there are much better manifolds out there what for sure would so my question is why not upgrade and not worry about it?
I have an recommend the Edelbrock.

how is your low end with the edelbrock
everyone seems to look at the high end . above 4k with everything.
if im going to replace my stock one, i want something that will create power down low as well as flow up top. i more concered about the low end power i guess.

I would just bore your throttle body to 60mm and port match the Y8 manifold. Then it should have no problem supporting 400whp. I am sticking with my stock Y8 manifold for fitment issues with my ZEX box placement.

throttle body is already bored to 58mm i believe. close enough ? 
Are you running the port matched y8 ?

I think I have 2-3 of them in our stash somewhere. Let me check tomorrow to see what I have.

Low end is fine. I also use a 70mm TB (Bored ITR). Creating power down low = wheel spin.

Ive seen both the Z6 and Y8 manifolds make 400~420whp.I think its possible they could make/support up to 450whp.

well... IMO any IM will be good to make 400whp ... add more boost and the air have will be pushed into the IM... it have no choice.
BUT a better design will just give more whp at the same psi... its just more efficient... and can give a better power curve.
I did 335whp at 20 psi with my setup using a y8... but I will bought a Edelbrock to get the full potential of my setup/engine.
Hope that my exemple will make thing clear...

Why? The stock Y8 TB is a 56mm.
The Edelbrock Y8 manifold performs same as stock bottom end and better high end performance.
Edelbrock also has a new 62mm TB that was at SEMA that's a direct bolt-on for the Y8 manifold.

Re: (OnePointSicks)
I think with 2.5" charge piping around 60mm would be ideal, but I don't think that the stock 56mm would be that much of a restriction.

Ah, he works there
Honestly, I don't notice any reduction and I am using a stock exhaust, header and cat for breakin. The top end power is amazing and you can here the VTAK kick in like a DOHC. I know, I am a ricer.
