t04b question
lets say i put a t04b with a .63 trim and a .90 a/r on my turbo II and i just ran it at 8-10psi, would the powerband be ackward? would boost fall off after it reached full boost?

no, that would be a pretty good setup. you would have good spool, ok top-end. but the boost i don't think would drop off.
but can you get a t04b with a .90? i thought only .84 and .96 were the only ones available under 1.00.

hmmm, maybe its .96 then, its a p-trim turbo, theres no name brand on it. i think thats what im going to do is run this t04b but only run like 10psi of boost as long as itll hold the boost till redline, that would be awesome.

Whether it holds a certain boost level till redline is mostly only affected by the hot-side. Also, the wastegate, and manifold would also be big factors in determining your boost-pattern and powerband. With a .96 A/R and the P-Trim, you should be able to hold that boost till redline and higher. It also means your powerband is more affected by the turbine-side rather than the compressors-side. However, depending on which model T04b you are using (I don't know what the .63 is) you won't see that great of a power increase at only 8-10lbs boost compared to about 13-18 lbs boost.

im going to buy using an hks cast iron divided manifold the exhaust side is also divided with a hks standard wastegate for either 10-14psi. when should i see full boost on this turbo? if i was going for 10psi? and if i was going for 14psi?

with a .96 a/r on the turbine side and a p trim you would probably see 10psi very quickly.
but the HKS manifold is junk ultimately.
btw the .63 a/r he mentioned is the compressor housing a/r.
why are you so worried about only running 10psi? you'll need a standalone EMS anyway with that turbo. don't think you'll still be able to run the stock ECU...

I thought the HKS cast only came collected (un-divided)?

As far as I know, the HKS cast is only available in collected (un-divided). Their ss manifolds only available for the FD are divided though, I believe.
The manifold may be junk for many people trying fine-tune their powerband and get the most power out of their cars, but it works, and can be had for a very cheap price also. Very hard to beat value-wise.

HKS DOES make a cast fully divided manifold along with their stainless tubular manifolds. I wouldn't consider any of their manifold junk, however the collected cast manifold isn't what I'd call optimal, but it works and is cheap. Cast manifolds are very robust and last a long time.

Using a divided manifold and a non-divided (.96 is non divided) is a waste, either go fully divided (manifold and turbine) or non divided (mani AND turbine).
