Where are you located? We do any custom fabricating and looking for a ATS to design one.

make sure you got the MAF mounted on a part of tubing that has the exact same inner diameter as the OEM one or it'll mess up your AFR.

good luck!

I've actually gotten in contact with a race shop here (powel race shop). They've also built intakes for CTS-v's solstice', sky's cobalt turbo's and everyone whos had one made by them had AWESOME things to say. Plus they've built racing corvettes/cadillacs so I trust 'em :yup:

I'm going to his shop in the next few days to develop and build an intake, charge pipes and a DP :) should be fun!

Well I went to the raceshop today!! getting my intake dimensions measured, he's gonna contact me in a few days :) but he thinks he can get something together. John Powell is an awesome guy and really knows his stuff. I'm glad theres someone that close to me who can do things like this with cars.

But anyways here we are getting the intake dimensions measured. the airbox pops right out and theres actually no sound baffling in there.

I'm also getting custom performance springs made, YYZ springs, 2" or so drop but still retain travel, getting a downpipe made as well and hopefully an electric cutout.


..oh and just for fun.. heres some of the awesome corvette racecars in his shop

Cool! Any good fabricator can do this. Here is what we made for a prototype for the LY7 CTS:

That looks awesome! I cant wait to get mine together :) He's going to be making a fiberglass housing based off the stock airbox base with the filter sitting in it then covering it with a lexan cover.

But yeah we're gonna be looking into DP (with electric cut out possibly), different springs and yes, the intake.

Its already a cold air intake and with the lack of baffles... what will a custom made intake do/improve???

the choke points are the tubes going into and out of the turbo, as well as the tubes connecting the intercooler to the intake manifold...

A downpipe with a high flow element and a tune will yield performance results. The high performance Element will deliver the swoosh sound.

yeah the down pipe will be for the performance element.

I'm mainly getting the intake for the cool sound it gives the car (I seriously love the sound of an aftermarket intake lol) but after i get the car tuned to optimize the intake then it will actually give a good performance bump having it there.

The factory airbox doesn't really scoop deep into the fender area, go pop yours off and have a look. Its just a little piece of pipe(no longer than 6") that points to the grill. We actually found water spots under the air filter, so water is getting in there lol.

But anyways, hes gonna make a box from fiberglass that looks like the factory lower box portion, and also mould a fiberglass tube going down into the fender to scoop up cold air and bring it into the chamber that will house the cone filter.

But again, I'm mainly getting this done for the cool sound it gives the engine, I know it only gets ya maybe 2-5HP, but the deeper sound it gives and being able to hear the BPV is just something I gotta have lol

Well I built my own intake tube and it flows 10% more than stock using the stock air cleaner.
OBTW - I sent the tube to JacFab for air flow testing.

DIY Less than $100

Of course mine uses -6AN to hook up the fresh air line. I hid it under the tube so it didn't look like the air tube had a "woody".
I also replace the worm clamps with T bolt clamps fro a more positive seal.

I tried insulating it with header wrap.. No improvement performance wise,(lower IAT's when comparing IAT 1 & 2 to stock readings.
Also it looked like chit IMHO.

Next mod is the air box & filter.

Have a parts list with links - I just read your TB Upgrade post as I am gathering a parts list.

Of course you have to trim the pipe to get the curve correct. Next you will have to trim the couplers.
Don't have an invoice for the T-Bolt Clamps.

Honest question here, could that not be done with a 90* bend pipe and straight reducing coupler? Did you braise/weld the -6an fitting on for the hose or some other method of attachment? Do you have pictures of where you trimmed the pipe and where you attached the fittings?

Yes you could do it with a 90 bend tube if you cam find one in the right dimensions and mandrel bend. But I believe Mishimoto or ZZP had cel issues on proto type 90.

As for trimming and the -6AN fitting.


1) I just trimmed one end and took off small pieces until the angled reducer fit. You need a calibrated eye ball for this. lol Now once that is done you need to trim the couplers. Lastly if you have access to a bead roller I would roll a new bead at the cut off end. This will give you a better seal.

2) For the -6AN fitting. I loosely fit the parts together and marked the location, took it apart, drilled a starter hole and then used a step drill bit until I could force threaded it in. This thin walled pipe and trying to cut threads with tap is almost impossible.

Ah gotcha. I figure there was a reason you went with something other than a 90* bend. No bead roller here. Probably won't tackle this project myself or at least not for quite a bit of time. If you decide to make a kit out of what you've made though...let me know lol

When I was looking to create some aluminum hard piping for my cooling system (engine swap in my Subaru), I was able to get the piping bead-rolled by a machine shop. I don't remember what it cost, but not much - might be worth looking into that, Skizzo.

A lot of exhaust shops that have a pipe expander can put a die in to do bead rolling as well. I found a local shop when doing the IC piping on my Camaro years back and they charged me $20 to do like 4 or 5 pipe ends. Took em 10 minutes tops.
