Hello all! I'm looking to get some 2.5" couplers (90s, straights, 45s, whatever) and possibly some 2" piping/couplers/clamps for my hotside. Not sure if I'm actually going to reduce down to 2", so I'm mostly looking for 2.5" but if you have leftover pieces from your build that are 2" I'd gladly take them and put them to use. Thanks!

Oops, meant to post in the WTB board, is there a way I can move it or does a mod have to?

Yeah, I've looked at their stuff, really looking for used because their couplers are pricy and I only need a couple so I don't wanna get a whole kit off ebay.

 

They really arnt though. They are quality boots and cheap. I dont think you can beat the value there. If those are too expensive this might be a bad hobbie to get into.



What specifically are you after. Like what quantities of what.

 

I agree. Siliconeintakes.com is kind of my go to in a pinch. It's cheap, they ship fast and it's fine. Then if you need specialty reducers, long leg elbows or straight up funky size couplers then HPS or Vibrant. Those two can be pricey.

 

I mean pricy compared to what you get in the ebay "kits". Of course a couple pieces aren't much from them, but to make a whole hot side with couplers and everything adds up as much or more than the universal packages. That's why I was looking for others' extra bits before buying new.

EDIT: Specifically looking for 2.5" - 2.5" 90 degree couplers, straight pipes, clamps, and all of the above in 2"

 

Its almost always cheaper to buy a kit of random bends, couplers, and clamps from cx racing than buying exactly what you need from silicone intakes. And then maybe just a couple special silicone parts from either ebay or SIS.

 

I may have a bunch of this stuff, used. Lemme sort it out later today and take a picture

 

Here you go. My 2.5" collection is pretty lame, my setup only had 2.5" after the intercooler. My 2554 had a 2" outlet, so for ease of routing it stayed 2.5" from turbo to intercooler.

2.5": 90* for throttle body
small straight section
BOV T coupler
straight coupler
another ~90* pipe

2.5" stuff

2-2.5" adapter stuff: long 90* 2" pipe with hose barb
2-2.5" 90* coupler x2, that hole is 3/8NPT for a GM AIT
2-2.5" straight coupler x2

2-2.5" adapters

2" stuff: 120* bend
small pipe coupler
~6" pipe
90* pipe
x2 45* couplers
straight coupler

2" stuff

Various T-bolt clamps. Haven't checked the sizes on this stuff, but 90% of them were bought for the pipes and couplers above, so they're mostly 2 or 2.5" compatible clamps. Probably a few ~2.75" for throttle body stuff.

T-bolt clamps


Rough estimate, this is all like $200+ from silicone intakes, not including shipping. That BOV coupler alone is $20, so are most of the reducer bends. I'll take $125+ actual shipping for the lot.

 

Nice, exactly what I was hoping to see here! I wouldn't have a use for the bov T coupler, but as for the other bits, are they from a previous build to where they can just be dropped in, or will I need additional pieces? Primarily on the hot side where you have 2" piping.

 

I actually need a silicone BOV T piece.. maybe work something out?

Could use the GM IAT section too.

 

It was from a previous build, yes. I changed around a few pieces to temporarily run my 1.6 N/A, then installed a 1.8 and a proper intake. So I’m not sure if it would still work, plus you’d have to run the same inter cooler and turbo manifold in the same place for any of it to work. And it would technically require the BOV T you don’t want. It would be 100% up to you to figure out if it’ll work for your setup. Let me know.

 

I have some bits now, enough to pretty much complete my cold side, so I'll take it. Would you consider $105 shipped? I don't want the bov T (maybe muthagoose will buy it?). I don't see the hole for the IAT, but if it's for the cold side, he can have that too.

 

Sure, I’ll PM you two

 

Thanks Curly! Got them all installed, awesome quality and condition on everything! Now I'm ready for a tune

 

 

Of course! Getting my STI exhaust fit on tuesday, so I drove home with nothing behind the turbo. About 3min on the highway, my speedo stopped working >.< After I got home I looked and my wideband wires melted into the speedo cable, but not much so I pulled it off and nothing was exposed on either end. Do I have to replace my speedo cable now, or is there something I can try to do to fix it?

 

Not gonna need the other fan?

 

 

Not half bad for a cobbled together system! The trimmed coupler you have at the intercooler inlet is technically the one I trimmed for the throttle body, but looks like it'll work there too. If I had one criticism it would be that you went from 2" to 2.5" and back to 2" off the turbo, staying 2" might save some room around the radiator. But I realize I didn't exactly ship you all that. I was able to simplify my routing a lot since I didn't have power steering, glad it all worked out!
