I could probally search around forever and find the info, but im really sleepy...so no..



Ok, I'm building myself some 2.5" upper intercooler pipes for now, then I'll build the lower ones afterwords.

I'm thinking doing the upper IC pipes should be pretty easy. I am just going to buy the mandrel bent mild steel from jcwhitney or something, then MIG weld er' up, then have the whole thing ceramic coated so it won't rust and it looks shiney. I like shiney.

Has anyone else done this and has the numbers for what bends work the best, and where to find those plastic/rubber couplers for connecting the hardpipes to the intake etc etc.

Thx for any and all help. If this goes really well I would be more than happy to help some other people out by making some pipes for them.

My suggestion is enlarging the "snorkel" hole and running the upper intercooler pipe through there. By going that route instead of through the side fender, you cut about a foot and a half worth of pipe length. Not only that, but it's much easier working with the pipe then.

I'm thinking about doing this too, but I don't weld. Though I'm sure I could find someone who does. I'm looking to go sp61 soon and will need new IC and pipes to really enjoy it.

Hey, you are in Minneapolis. I'd be more than happy to help you out if needed. I have a full metal shop with about every tool other than a mandrel bender a metal worker would ever need. I would insist that I had some test runs though so I could ensure good quality welds.

I'm sold- Once you get yours put together, Ill order myself some bends. You could even use my car as a testbed if you want- I have to fix my drivetrain problem first though : / may need a new tranny... :mad:

I have made many sets with the JCW 2 1/2 pipe. You will need the car with you, because you will need to know all the angles. I made a extra set so i now go by them. The best way to run the upper pipe is through the snork hole. I have done the one through the fender and it is a lot of work, plus like other have said it is extra pipe for the air. The best thing with the pipes is you can hit about 8 to 9 psi with out any boost controler. It is amazing how much better they flow and the turbo spools up so much faster also. :bigthumb:

I did the JBL thing, with some minor modifications. Worked out great. I boost 10 lbs daily and I commute ~ 70 miles a day.

I didn't have to enlarge mine at all, the 2.5" pipe fit through fine. But if you want to run a CAI through there as well, it will need to be enlarged.

I got my couplers, reducers, & clamps from HTS, not the cheapest but competitively priced, and definately high quality, with fast shipping and great service. They've been working great now for ~4.5 months @ ~15-16psi on a DD, about 8k miles, with no problems.

I don't know about other companies, but with the sizing HTS uses, you order hose/couplers/clamps in the same size as the pipe it will go on. The TB, iirc, is 2.75". HTH

I was just looking at my car this weekend, and to use the hole near the headlight, I'm assuming that I'll need to remove the washer fluid at least, and probally figure out something for the FiPK that seems to be in the way as well. Hmm...

My cardomain page has pics of my piping which I used 2.5" JCW al-steel u-bends. You only need like 4-5 to do it depending on your IC outlets (I have the NPR large and needed a straight section too.)

Who ever asked--2.5" couplers fit 2.5" tubing (and a little loose on 2" pipe)

The link to my site is in the www link under my screen-name
