Mechie3's 818S

[Mechie3]

What are you doing about the atmospheric pressure sensor that is built into the driver side secondary air pump valve? Is there a way to change the offset of the MAP sensor to factor in atmospheric pressure?

It only affects the 07, not the 06 WRX. I ditched the airpump back in 2007 when the WRX was my daily driver. Never had issues. It wasn't until the 07 came along that people started having problems when they deleted everything. Haven't had the pump or valves since.

[JeromeS13]

Awesome! Makes me really glad that I have an '06 donor. Thanks!

[Mechie3]

The service manual still shows an air sensor in the one valve but its just a backup or something. There's a large thread on nasioc about it and consensus was 06 doesn't matter, 07 you can cut the sensor off the rest of the valve and ditch everything but the sensor.

Where are you guys finding the service manuals for these cars....

Good deal. That's one more piece of useless crap that I can get rid of.

I think I got mine from Ebay? Mine is just a series of .pdf files. But, it comes in handy if you know where/how to look and use it.

Ok just wondering. Ive seen the ken gilbert site. Just wondering if there was another source out there.

How many sources do you need? I downloaded the entire service manual for my '04 donor from that site. For free. The fact that each chapter is in an individual pdf IS kind of a nuisance, though. You'll need to set a little time aside if you want to print the thing. But the price is certainly right.

[07FIREBLADE]

I was just wondering if there was anything else out there. Computer doesn't like me and wont let me save the pdf file for the 02. Oh well, i was able to download and save the 06 manual for my dd wrx. Current donor is the 02. I was looking for a dvd copy if there was one available thats all. I hope this answers your question. The price is perfect and the only other thing we need now is the actual assembly manual.

I got a cd from ebay for my 2002wrx for $5.00. It was a complete copy of the factory manual.

[Mechie3]

Made prototype #2. I like it much better. It's shorter, but with a bigger diameter cap. The o-ring compresses axially now so there's little resistance until the o-ring bottoms out. The black part is plastic since it's just a test piece (didn't even finish the flange). I learned how to program and cut threads on the CNC, so that eliminates another issue I had with the threads not always starting straight.

[Bob_n_Cincy]

good work Craig, looks great

[longislandwrx]

I'm looking for something similar but it needs to accept an OEM cap so I can use the AOS.

I don't suppose you want to start over?

[Mechie3]

Nope. Lol. I don't have a tap big enough (M42 IIRC) which is why I went to the smaller M24. Don't have internal threading tools either for the CNC or manual lathe.

[Mechie3]

Made the bottom portion in aluminum today. Fine tuned some of the process. It goes on much smoother and make a nice seal. I'm considering doing a short run of these as there's been some interest in them.

Rev 2 on left, rev 1 on right.

[07FIREBLADE]

How much?

[JeromeS13]

Count me in. Did you ever finalize your alternator mount as well?

[Zodiac]

same here

[metalmaker12]

Let me in on that

[Mechie3]

How much?

I know of someone else who makes them for $80, so definitely not over $80. I'll have to add up times and material costs to see what makes it worth it. It would come with the stainless steel cap screws too. I think all WRX are the same, but regular impreza are slightly different. I'll have to contact FFR too to see about milling an 818 logo on the top of the cap. Not sure if it's copyrighted or trademarked and don't want to infringe on them even if it isn't legally protected but they don't want me to.

Count me in. Did you ever finalize your alternator mount as well?

lol. Not yet. It's one of those things where it's close enough to being done that I temporarily lost interest. By that I mean my wife keeps asking me when I'm going to finish the patio.

[metalmaker12]

I hear ya on time, put it this way, you make me two and I will make you a custom dp/ exhaust even trade if not to elaborate.

[Mechie3]

We could work that out. I know what I want it to look like, not sure if it'll fit with the trans. I'll have to see.

[flynntuna]

That is a very nice piece, it seems to solve the problem of adding oil to the engine. On that note, is the stock fill tube reversible so that it faces the rear?

[07FIREBLADE]

I was gonna ask if you could do the 818 on the cap. Glad you had it in mind. Hope you can....

[Mechie3]

That is a very nice piece, it seems to solve the problem of adding oil to the engine. On that note, is the stock fill tube reversible so that it faces the rear?

I can check tomorrow if I remember. You'd have to use a funnel with this. The hole is about the same size as the stock tube, but there's no large cup on the top to prevent overflow.

[THE ITALIAN]

That is a fine machine job. & good idea, Let me know

[mekohler]

I am interested as well, 818 on it would be a big +
Great work

[Mechie3]

On that note, is the stock fill tube reversible so that it faces the rear?

Checked this morning. You can reverse it so it faces the rear, but it also makes it face horizontal as well. Probably not what you're looking for. lol.

[wleehendrick]

For under $100 with a logo, I'm all over it! However, one thing to consider... factory caps have plastic touch surface for a reason. I can see someone branding an 818 logo into their hand by grabbing a hot Aluminum cap!

[Mechie3]

I used a metal cap on my plastic filler tube for years, and it did get uncomfortably warm. I'm sure with a metal/metal/metal contact it'll get rather hot. Nothing a rag over your hand can't fix if you don't want to be in the 818 club permanently. haha. I could make the tops from Titanium, but I'd have to buy a special tap that would likely cost me $500. Plastic could be done too, but that isn't much fun.

[Mechie3]

Time to machine the cap: 10 mins
Time to machine the logo: 12 mins

Ha!

Certainly looks pretty nifty though.

[Frank818]

Wow that's nice!

[flynntuna]

You guys sure know how to spend my money. LOL My budget is growing exponentially.

[wleehendrick]

A little lacquer in the milled areas and it's perfect!

[Mechie3]

Great minds think alike.

[07FIREBLADE]

Who do I make the check out to this time

[longislandwrx]

what about a Delrin cap? Delrin is super cheap and your tools should have no problem cutting it.

A block big enough to do several caps is like $10 on ebay.

[THE ITALIAN]

I'm looking for something similar but it needs to accept an OEM cap so I can use the AOS.

I don't suppose you want to start over?

Cannot this AOS be done somewhere else? I know it is important just for detonation, not to mention having a clean induction system, but MORE tubes on the top is just messy.
I use a clear tube on my roadster so I can see what comes up, but I don't have a turbo or intercooler. A catch-can is just another item to clutter the engine bay. OR perhaps a dry sump $ystem !

[Mechie3]

He probably has the grimmspeed AOS which screws into the stock oil fill tube for easy installation and a somewhat clean look.
