What type of pipe and where did you get it from for your intercooler piping? I was thinking of some mild steel with mild steel mandrel bends, or are silicone bends better? Any help would be greaty appreciated.

Alot of people including my self get there piping off ebay because its cheep and come with silicone connectors and clamps. Most people use either 2" or 2.5" stainless steel or aluminum. Some will go with all 2" or all 2.5" and some will go 2" on the hot side and 2.5" on the cold side.

Yup. Just get on eBay Motors and search for "aluminum bend" (no quotes) and you'll find loads of sellers. Usually all it takes are 45 degree and 90 degree pieces. I used all aluminum except for one steel piece (an exhaust pipe, actually) at the throttle body inlet so I could MIG weld a few fittings to it. (The TB inlet is almost exactly 2.5")

Worked fine, although we didn't end up using the couplers, they seemed ok.

so do you guys typically use the couplers over welding as many pieces as possible to prevent blow-offs? or only for high boost situations?

If you can weld aluminum, thats better of course, but couplers are fine. Try hard to keep them to a minimum, although they sure make fitment easier. Just less connections to fail, the better. If at all possible, roll the ends. Someone somewhere near you must have a bead roller for when everything is cut and ready. T-bolt clamps are also great, but not too tight. Aluminum really keeps it cool, my coldside pipes are cool to the touch after drag racing. What about your BOV and Idle air control valve connections? You might need to use steel if you can't get someone to weld aluminum connections on.

JB weld is an option for those also.

Don't trust the t-bolt clamps that come with the ebay pipe kits. 4 of mine broke after a couple days driving on salty roads last winter.

The welds are a bit weak, we strenthened them with an extra weld. But you shouldn't be driving on salty roads, anyways. Next time I'll send my civic over on the ferry and you can borrow it.

I've heard of people using it before on this forum, but how strong is JB weld? If i have to weld i could use steel at the tb like Joe perez did right? I just don't know if i can fully trust jb weld.

JB Weld is fine, heck permatex could be used. Just use a X" threaded pipe and drill & tap accordingly. screw in the pipe with sealant and you should be worry free.

It's how Jim B made money for a looooong time.
