Hi, I'm back!
Somehow the website reminded me that I have a few new posts here through email.
I was waiting for some people with more sense and experience to reply to my post.
There are some production cars that has ITBs with FI, for example R34, R32 and some people put Screw type and Centrifugal type on E92 M3.. you can also look into twin charged Exige.
Yes, it doesn't really matter which way, turbo or sc, both's problems can be dealt with some creativity.
The supercharger kit I've been looking at is indeed the SoS one, although I don't really mind the kicks in power.
I was looking at something similar like this with the turbo impeller facing towards the headlight or moving the intercooler more forward for the supercharger.
There is this double barrel ITBs I really want to put in, but space is an issue with barrel type.
I'm not in a hurry to start the project since I have a few more year to prove my skills/setup on the track to my friends in Canada.
Again, the car will also be used on twisty mountain roads.
Thanks for all the replies!
