What's needed for IC piping install Options

[Rjb23]

Ok, I'm gonna be taking off my top mount and putting my fmic on in a few weeks. What do I need to do that, I know I need the basic stuff like ic piping, couplers, fmic and mounting brackets(obviously), all that stuff I have. But do I need BOV or BPV, MBC or anything extra like that? I'm still running stock boost and plan on running stock boost for a little while after that.

yes....bboy is right, if you get the hks and recirculate it, it will be pretty much the same as an mr2 bov. its a silly thing to do for mr2 guys, because they already have a good bov to start off with, and you loose 90% of the sound when u recirculate the hks.

well they sell the recirculation adapter for the hks ssqv (i have 1, not installed) its just that u need to run a 1 inch hose back to ur intake pipe...then the hks wont cause anything to go rich in between shifts

The whole recirculation thing is another thing I don't completely understand. If the air is being let out to relieve pressure on the turbo, why is it that recirculating the air back into the intake pipe does not reintroduce the same pressures to the system?

because the whole stress on the turbo blades happens after the turbo outlet... when you recirculate your are realeasing that stress from that location and moving it before the turbo.

think of it this way ... if you attach a boost gauge before the turbo, you wont see any boost on the gauge because there is no presurized air there.
