Bought a Turbo Kit getting ready for install Block off m90 or Keep it? Why

I bought a turbo kit... car tuning.
I have 9.9:1 pistons intense stg 2 cam stg2 heads 110# valve springs and too much other stuff to list

My questions.
I have a giant 3.5" intercooler core air-air Im already using the m90 liquid to air phenolic Use both or just use the m90? *save weight*?
The m90 itself.... pull the impellers or keep them in

It is a ported housing and LIM, 42.5# injectors...
3.0" pulley

I have a small turbo that came with the kit but I will be upgrading it to the t78 I bought in the future.

I was wanting to know if I would be better off spooling the Big turbo with the m90. Should I pull the impellers or keep em?

Thanks for any and all advice.
 


If this were my car here is what I would do:

Get an L26 upper and lower, install them and use the FMIC.

Twincharging is cool but inefficient.
 
And the sell the SC, sell the IC core etc and there's more money back in your pocket.

I have a similar build with a phenolic intercooler and an air to water heat exchanger. I have been thinking about adding a turbo to the mix. the idea i'm stuck on now is just adding the turbo kit and using the air to water intercooler with the block off plate installed. a friend told me that to make 400 hp, the intake manifold has to support 600 cfm of air, and the gen 5 pushes about 540 cfm, so I think my ported supercharger case and machined lim will support about 400 hp.

since the air to air intercooler came with the kit, you might as well use it, and probably should use the intake setup Decker suggested.
 
Why get the different manifold what is wrong with just pulling the impellars? I do realize the m90 is going to be a hinderance to a turbo only made to put 400 whp on a mostly stock car, but the t78 can make quite a bit more power top end would the m90 with a stock size pulley be a bad idea just to spool it up?

Thanks for the input. I have never turboed a car I am really new to builds in general.
 


the supercharger rotors are designed to be turned by a belt, I dont think the air from a turbo would turn the rotors

its probably not a good idea to install a turbo with the rotors still in the supercharger
 
And I believe Danomite or w/e his name is on here that's twincharged even recommend not doing it because it wasn't worth the hassle.

No its purple and looks gay. All the more reason to stuff thousands of dollars in it. Can text ya some if you want compg IDK how to upload.
 


The rotors continue to spin as the car makes turbo boost the kit came with a blockoff plate to actually pull the snout and impellers sorry shoulda clarified that.
 
I was just suggesting posting a picture in case I've might of spotted the car before. Trust me we have probably all seen worse

I bought a built trans from a member here a while back
7/8 chain input shaft clutch shaft something 3.29 gears... maybe some other stuff cant recall too much. Hes the same guy I got the zzp shortblock from
 
KABOOM. Just saying... :-P.

Man I didnt know it was gonna turn into this or idve gone big turbo out of the gate... Ill upgrade it when and if it snaps.
I tried to find the post but couldnt track it down. there is a small chance I got it at clubgp.com that is where I bought the cartuning kit.

I also wont be putting on the t78 until I sell some other stuff because I would have to get 80# injectors and have a welding shop fab me a DP. Its gonna be the little turbo for now.
