    Alex's CGT - 7A Swap - Got Lip?

    I've hinted at this for a while now, but figured I'd start a project thread for this. As if I needed another project, my friend made me a deal too good to pass up so I picked up this 1986 Audi Coupe GT.

    1 owner until May '14. Supposedly the car had been sitting from 2002 until then. Super clean! Minus the 'matching' dents on the lower part of each door...
    Kirk got the car running, but was still fighting a 'brick wall' at 3k rpm's. I troubleshot some more and replaced more parts to no success. I'm pretty certain I have a CIS curse.

    Soooo.... NO MORE CIS!

    Road tripped from Seattle to L.A to pick up a full 7A swap (engine/wiring harness/ECU/etc) from Chris/varia. Did about 2600 miles in 4.5 days, but it was great. I love a good road trip.

    Started cleaning the engine tonight. In case you didn't know, oven cleaner makes for a great degreaser for a first pass before I break out the pressure washer. Works better than purple power/simple green, just don't leave either on for very long. The oven cleaner foams and clings which gives it a better change to break down the grease.

    Foamed up:

    After a quick scrup with a brass brush and rinse with a little hand pump water sprayer:

    IMG_20150212_210443223 by alxdgr8, on Flickr

    Another round of oven cleaner with the hose/pressure washer should get the block nice and spiffy.
    Going to paint the block, powdercoat some stuff, ceramic coat the bag-o-snakes, do some seals/gaskets, and upgrade the injectors.
    Also picked up some H1/H4's, Jamex strut bar, 2Bennet coilovers, and TSW Hockenheim wheels. Front struts of the coilovers need rebuilt so I'm going to buy some new ones. Also need to pickup some strut mounts and install some Mance mount savers into.

    End goal is to make this a fun and reliable DD so I can sell the Toureg. I'll DD this and the Merc (when I get that fixed soon) so I can save some money to get a Focus RS when it comes out in a year or so.

    Got the head off, lots of carbon buildup but the bores look clean with hatch still present.

    Did some more degreasing and cleaning. Also started blasting the header in prep for ceramic coating. Lots of nooks and crannies to get to! Going to be even harder to spray it with ceramic.

    a header is always a fascinating thing to look at. Are you going to coat it, or have someone else do it?

    I'm going to do it. I did it on my V8 headers (which I haven't run yet so who knows how long it'll last). None of the DIY stuff is as good as Swaintech white lightning, but it'll be better than nothing.

    I should have cleaned them up (PO welded them), but I don't plan on keeping the 32v in the car too long so I decided not to spend much time on them. They don't leak and you can't see the welds from the engine bay.

    What blasting media did you use?

    I've done the DIY ceramic coating a couple times. Didn't last on the dirt bike header, but that gets blasted with mud constantly. I haven't checked the gti manifolds in a while.

    Mainly aluminum oxide. For the V8 headers, I did an etch with glass bead between the high temp ceramic primer and the chrome ceramic top coat. But that was when I had glass bead in my old junk blast cabinet, that got thrown away when I moved. So I'll probably just etch it with the aluminum oxide at really low pressure between coats.

    What ceramic coating did you use? I used TechLine Cermakrome sprayed with a HVLP gun and then baked in my powdercoat oven.

    Buddy over in ID makes some various poly mounts for Audi's, so I ordered some engine/trans/subframe mounts from him. Got 80A durameter for the engine/trans and the subframe come in 95A.

    I used Techline Black Satin, sprayed out of a cheap Harbor Freight airbrush, and cooked in my powdercoat oven. In hindsight, I probably should have sprayed it on a bit heavier.

    Ah, pretty much the exact same setup then Would be interested in hearing how your car header is holding up.
    I actually had to blast off one of the manifolds after I sprayed it too heavy the first time which caused cracks/peeling during baking. Stuff is a pain to blast off!

    Got some new toys and they're already getting a workout! Steam cleaner cuts right through grease, even better than degreaser and the pressure washer. The air-powered vacuum is also really handy for sucking up whatever on engines and anything else around the shop. Easier to grab with the air hose than lug the shop vac around.

    Got the block cleaned and degreased in prep for paint. Got some Duplicolor engine enamel primer and 'aluminum' color. Will be much easier to tell where oil leaks are coming from over the black paint...hopefully there will be none!

    Harbor Freight, it gets surprisingly good reviews (and isn't one of their brands). Came out to like $115 after tax with a 20% off coupon. They occasionally go on sale and drop below $100 with a coupon at HF. This model runs $140 other vendors.

    Yeah, no one tool will remove everything. I've used a combination of oven cleaner with a hand brush (be very careful with aluminum, don't let it sit long), pressure washer, steam cleaner, and parts washer with citrus degreaser to get everything clean.
