yeah......well all of it is an interference fit.........all the pieces are pushing against each other etc.  none of it slips on.  its a PITA to install, but if it doesn't come apart easy, then the pipes can't move to let the air out.  I went to great pains to have no rubber elbows, just short sections of silicone.  We'll see. :)

06-02-2026 ATLAS Z UPDATE: Well parts came in, so I was able to put together my T fitting for by boost switch and vacuum source for my Blow Off Valve (BOV). I used the tried and true 567 sealant on the threads, and then I covered the lines with some of my plasti chrome wire loom and plasti-chrome tie wraps. Not too bad, huh?

06-06-2026 ATLAS Z UPDATE:  I put everything to the side and worked on engine harness wiring.  Not hard, just VERY time consuming.  I had opened up all the wiring, and now I am custom tailor-ing it to the setup here.  Making good progress.  Cutting the tie wraps connectors as needed to slide under bolt heads and tighten back down and had to make 2 large ones out of aluminum to put under a couple bellhousing bolts.  The idea being keeping everything off the firewall and sides.  they are shaved, and everything needs to look separate and tidy.  I am putting the chrome wire looms over it and making steady progress.  PICS: :)

06-12-2026 ATLAS Z UPDATE: the MAF meter I had bought was supposed to work on my 2006 model year wiring harness.....but it didn't. So I searched and searched before figuring out that the MAF was molded in to the intake pipe. So, I found one on eBay and it arrived today. I held the other meter up and took measurements and then cut it to length, cleaned it up and then wrapped both sides with self adhesive rubber strips to fit the 4" couplings. Doesn't look near as good as the other MAF.....but I didn't have a choice. By the way, 2006 was first year for MAF meter on 4200......it changed in 2008 to a different style, so if you have an '06, dont forget to get this piece. PICS:

11 hours ago, flatout said:

you may have mentioned this at some point previously, but what ECU is this going to run on?

The factory 2006 GM ECU, called a "P12".  Jeremy Gonyou at Lime-Swap converted my engine harness into a stand alone setup and cracked my ECU and programmed it for the turbo.  By using a factory setup I retain the variable valve timing and the wireless throttle.  60lb/hr Deka fuel injectors and with an 8 psi spring in my external wastegate.....around 350-400 hp at the crank.  Very mild setup.........well over 300 at the wheel, which in these cars is sufficient. :)

06-13-2026 ATLAS Z UPDATE. Today I finished screwing down the carbon fiber and installed the front flares. Pretty much all done. Later I will tape off both sides of each edge and lay in a coat of black pure silicone....then pull the tape off leaving straight lines and let it harden up. Then some paint correction and some clear and the body will be done! I gathered up some parts I am taking to get wrapped in dry carbon fiber (front bumper, cowl, and rear spoiler). PICS:

06-14-2026 ATLAS Z UPDATE:  I started the day by cutting and prepping a new throttle to be welded up, keeping the angles for leverage, but removing and bends to make it straight. the one I did before did not work.  It needs the bends to create leverage, and a spring mounted throttle foot pad to work correctly.  the factory one is bent, so pie cuts were used to straighten it, then chopping and shortening it was required.  It now heads to Wagner Fabrication to be welded up and then I will paint and install later.   Then I Mounted my dual catch cans.  I then mounted up my front blinkers and then went back to the catch cans....tying all the lines in,  One line is black braided, and as you can see, I masked off a portion of it and painted it with silver engine block paint to help it match the others.  Better than not at all! :) I also wiped down my forward metal dash piece and set it in then and then touched up some fittings in silver to get away from too much black.  I then took my blinker surrounds that have been repaired and sitting in primer forever and sanded them up smooth with some 320 grit sandpaper, and painted them with gloss black rustoleum 2X, and then a few coats of Krylon clear.  Also of note, I did cut and place a PCV valve in the breather line coming from the intake back to the catch can.  So....a lot of little things today, to include tying it all up and cleand up under there.  Definite steps forward today!  PICS:

06-18-2026 ATLAS Z UPDATE:  Well, after having people tell me about the intake and issues I will have with the MAF meter, and then researching on it, I decided to just redo the intake from the MAF sensor forward.  I ordered some 4" pipe, a coupling and clamps and dug in.  I did a layout and then cut the hood to start the process of making additional room for a smooth long radius 90 in 4" along with a vortex air cleaner to give the MAF Meter what it needs.  In just a couple hours tonight I got a good start on it.....but I will have to do a notch in the radiator support to get the pipe to where it isn't being forced up over it.  I am still waiting on the Air cleaner, but the job is well under way  PICS:

06-19-2026 ATLAS Z UPDATE.  I picked up my gas pedal from the fab shop today.  I got it home and wiped it down, masked it off and gave it a couple coats of Rustoleum 2x gloss black paint.  Should be ready for install tomorrow.  PICS:
