ok so ive been doing a stupid amount of research and want to know whats the best tb to match up to the v5 magnus intake manifold....? I was wanting to run the boomba tb but what has me confuse is the intake manifold has a 90mm flange? Question would it be best to run a 90mm throtle body to match the intake and a 3.5mm intercooler piping? Throttle response isn't a must as i will see power around 7k with a built 2.0....

 

im guessing you 3.5" ICP and 90mm should be perfect. 90mm is roughly 3.5" so shouldn't have step issues.
