if i use 2.5 inch i/c piping. which t bolt clamps do i use, and what size silicone couplers do i use
like it says, i want to use 2.5 inch i/c piping, but my question is, when i get silicone couplers do i get 2.5 inch inside diameter? and what size t bolt clamps do i get? 2.5 tightened down or 2.5 inch all the way open?
my one pipe i am keeping 2 1/4 which is from the throttle body to hte fender. then i want to run 2.5 for the rest of the piping. i have like 2 inch piping now, and i think the couplers leak because some of them have cracks in them and the boost leaks off at higher rpms.
let me know. thanks, vernon

If your IC piping are 2.5" O.D., then the 2.5" I.D. couplers should work. Get the tbolt clamps that are 2.5" tightened. 2.5" opened will not allow you to tighten them when you account for the thickness of the coupler itself.
BTW, get new couplers, it'll save you the hassle of chasing down boost leaks later down the line. And you'd want to keep the same diameter piping all around. 2.5 from the turbo/IC, then 2.25 to TB after is only a bottle neck.

yeah but the pipe that i have from the throttle body to hte fender is 2 1/4 i believe and it already has the flange for the bov on it. and my turbo compressor outlet is no where near 2.5 inch its around 2 inch. and my charge pipes now are 2 inch from the turbo to the inter cooler which has 2.5 inch openings then 2 inch to 2 1/4 inch to the throttle body.
so i want 2.5 from the turbo to the intercooler then 2.5 inch from the inter cooler to the fender where the other pipe is.
but i have a feeling that my couplers might be leaking because they have some cracks in them and my boost falls off at higher rpms, which i think is the reason for it.

also for the bends on the passenger side, i need to 90 degree bends correct?
one coming from the inter cooler and one going up into the fender well?

How much boost do you plan on running?
I'd say just keep it 2.5" all around. It shouldn't cost too much to fab up a 2.5" piece from the fender to TB, then weld the BOV flange on it. You can probably use a cold air intake tubing that goes down to the fender and weld a BOV flange on that.
BTW, what turbo are you running? If it's a smaller turbo, that might explain the boost dropping off at high rpms, it just runs out of steam.

well i am running a greddy 18g right now. and i am running about 8-8.5psi peak, then it slowly drops off to abour 6.5-7psi.
i think the i/c pipes might be leaking off some air but i'm not completely sure. and it wouldnt hurt for me to upgrade from 2 inch i/c piping to 2.5 inch piping and get better couplers and clamps. because of the amount of boost i will be running when i put my other motor in.
i know it wouldnt be too hard and too much money but do you really think that that extra quarter of an inch from the fender to the throttle body will make a difference?
that piece is out of a kit and it was made with the flange on it and it has a bead on it.
