I just ordered all the fittings to somewhat replicate your setup (love it). I already had the Nuke rail on order, just needed to get a visual on the hoses. Another question haha, how did you fit that -8AN fitting onto the valve cover? Did you cut in threads?

Nice.

I had an aluminium welder attach it for me. Although, I'm not exactly sure how it is sitting in there to be honest. The original port isn't threaded and the fitting isn't welded in, so he must have used some sort of adhesive or something to hold it in there. It is solid, but yeah not sure to be honest.

I gave the welder a male to male -an8 to 1/2 fitting (if i remember right :/), with the hope he could thread the stock blow by port and thread this in, but apparently he couldn't thread it, but it is nicely stuck in there somehow.

Yeah, maybe it could cause a leaner condition in one cylinder than the rest, but it's N/A so maybe it's not that detrimental. I mean, I can't imagine all these other unopened 25 year old M20's on the forum to have perfect AFR's either and they're doing fine.

I saw the line into the valvecover. Looks really sleek. I welded mine shut and plumbed two -AN10(?) fittings on the cover, but I have a stock intake manifold to conceal most of it. Your option follows your motor's lines better with the ITB setup.

I'm in the process of gathering info to change everything else to -AN fittings (fuel, vac, maybe even water) and your bay was a fun/informative example to look at.

Thanks mate.

I could see converting all the vac lines to -AN fittings could be a 'fun' experience lol will look great when it's done though. Rad hoses/Coolant lines would look awesome it all converted to -AN fittings. Wouldn't be a cheap exercise though since all the coolant necks would have to be threaded, or have a threaded bung welded to the end. Would have to be pushing towards -AN14 or so sizes so all the fittings would be mega $$$. But hey, would look great when done and you wouldn't have to worry about split hoses anymore :)

Thanks so much for the pictures, like they say "worth a thousand words." One last question on the topic, approximately how many feet of hose did you use?

No worries, yeah a picture is so helpful when trying to explain the smaller details.

When are you guys going to move into the future and start using the metric system lol but at a guess, would probably be close to 6-7 ft or so. But depending on how you're planning on running your lines, just measure befor you order. Nothing worse than being 100mm short when it comes time to install. lol I have been down that road befor...

To be honest i haven't thought about it, but you're right all the blow by going into the same cylinder might cause some problems long term i guess, time will tell.

The setup didn't come with a port for a catch can, we drilled/tapped a hole and threaded in the port for the catch can. I wasn't overly keen to just run the blow by to a can that just vented to air.

I also had a -AN8 fitting threaded into the blow by port on the rocker cover, so that I could run AN8 lines.

I like the catch can setup and lines. Did you make a hole yourself in one of the intakes to plum the line or did the setup come this way?
Ever worry that 1 cylinder is going to get all the oil vapor rather than spread accross all 6?

Im interested in knowing more about your AN fitting fuel system. What fuel pressure regulator did you use? Did you run the braided hose all the way to the tank? More pics please?

Hey mate, I just went out and took a few shots of the system. It's a pretty basic setup really, but works well and cleans up the bay nicely.

I have just run -AN6 lines to the stock hardlines on the firewall. So I haven't run all the way back to the tank/pump. the pressurised line to the fuel rail, which loops back around to the reg, then from the reg down to the return/drain line. I'm using the 'Nuke Performance' fuel rail which comes with -AN8 (if i remember right) threaded ends. So just used a reducer in order to run -AN6 hose.

I am using a 'Hybrid Racing' fuel pressure regulator. (Hybrid racing make Honda kswap parts, my old civic was sponsored by them a few years ago) but the fuel reg is universal, so it does the job.

haha I am just waiting on parts now. rebuilt s54 is sitting on the stand and the harness, subframe and oil pan should be done soon. then off to paint

Nice man!!

Lol I meant on the car. I know fuck all about photography.

haha whoops. Yeah same.

Thanks mate, the iphone6 does alright sometimes. I need to learn how to use a 'proper' camera and get some better shots though.

damn your car always makes me motivated to finish my white mtech2 touring

Get to work mate haha

Great shots. You really handled the details well.
