inter cooler upgrade

what i meant to say was will it fit FACTORY SIZE pipe, not that i would reuse the old pipes, eventualy i want the same diamiter pipes but after market ones

Sure, it's a matter of volume and that's a HUGE difference in volume. Take a bicycle pump and fill a 1 liter bottle with 30psi. Then fill a 2 liter... which one takes longer? Also the smaller diameter piping grants a higher velocity intake charge (better at low RPM). I'm not saying the factory piping is great... I'm saying that.... oh god... can't believe I'm about to say it..... Bigger isn't always better.... This goes for intakes, throttle bodies, headers, exhaust and so on.

Factory IC inlet and outlet are 2". The factory piping is pretty crazy though and had restrictions all over the place where it's pinched down.

so what what would be the next step to factory pipes. i know i would need 2 pipe reducers to run this intercooler. im looking for a fast responding motor and what cre said about diamiter is just a perfect explanation, ( i know some of it because on my vintage race bikes im always messing whith velocity stacks for variouse tracks long and short.). i dont quite have the money for new intercooler pipes but i would like to optimize the facotry ones any idias?

u could simply get 2 couplings and some watever there called...the circles that have a bolt of them that u can buy at any parts store...uuugh failure....and slap those on the fmic. But im going 2.5" piping, slightly bigger, less restrictive, but not so big the engine is gonna be like WAFGJABFKJABFUAFKJ is happening lol and if u get spearco style fmic's (which we did) the pressure drop is practically nothing, and it will still be about the same level of responsiveness.

in the future i would upgreade the pipeing to a bigger diamiter in the future. since my goal is 550rwhp ill need about 600 to reach my goal. in the futer ill go 2.75 inch pipeing whith a bigger more modern turbo from garret but at the moment ill stick whith factory diamiter but i will optimize the factory setup. since at about 200hp per liter you start to lose responsivness i can worry about bigger diamiter later down the road when i have more cash to put into it
