Congrats, buddy!
Thanks guys! It's a truly unique feeling knowing you brought another person into existence and are now responsible for their well being. I can best describe it as a mixture of pride, awe, and fear.
LOL, VERY few people catch that for some reason. I think a sign of getting old is returning to the music of one's youth ('90's for me).
Price and package. The last time I checked the Mazdatrix lines were cheaper and they include all the parts needed while the Racing Beat ones require you to purchase the adaptors separately. Aside from that they appear to be identical.

No updates?
I know how it is about kids eating up progress lol.

Yep, even though my wife if taking care of Ian for the most part I've picked up the slack in other areas so garage time has been limited. That in conjunction with my radiator ducting woes has kind of turned me off the car for a bit. I'm hoping some inspiration will strike me and/or my exhaust manifold comes in and gets me excited to work on the car again.
Thanks Larry. Ian had his two weeks check up on Monday and he gained 20 oz in 2 weeks! It's certainly been a life-changing experience.
Sadly not much to update. I found a little time last weekend to work on the intake manifold a little. It's all painted so I installed the studs for the TB and the vacuum ports. I also filled in some gaps/inperfections in the runner with Quik Steel to improve flow a little. I still need to build it up some in places and with the colder weather that stuff is taking forever to dry so I can't go in and clean it up with the Dremel yet. The exhaust manifold is "next" on the things to do at the shop so hopefully I'll see that before the end of the year. Other than that Ian has been keeping my wife's and my hands pretty full and when he is actually asleep/calm all I want to do is veg out. Here's to hoping for a surge in productivity!

Be careful with that Quik Steel stuff. I used it on my IM when I deleted my VTCS and all the plugs but one were missing when I pulled the IM off a couple months later.
But glad the fam is doing well, man.
Yeah, that stuff sucks. We've had bad experience with it at work as well. Seems that quick steel doesn't expand and contract at the same rate of aluminum or even steel. It'll last one or 2 heat cycles and will eventually break away from the repair

Hmm, I used it in the past to plug the VTCS holes too (between runners) and I recall them all being there after a year or so. I recall it taking forever to set then as well. Fortunately it's not really "built up" in any locations and I really cram it in there. I just used it to fill in some of the gaps where the runners meet the flange so it's not like 1/4" chunks would be liberated. I'll check out the adhesion if/when it ever sets and decide to keep it/scrape it out then.
Some pictures to hold you guys over.
Finished intake manifold (painted w/ all fittings):
There are aftermarket cast aluminum thermostat covers available, but for nearly $100 I figured I'd just clean up my stock one. I removed the brackets and features I didn't need and painted it the same aluminum as the water pump housing. I figured the aluminum would flow better than black (its original color).
Working on the injector plugs today.

Got to play in the garage a little today. Not much to show. Finished modifying the injector plugs and I'm in the process of painting them now. Decided to finish painting once and for all despite temperatures <50 deg F. Painted the water pump and installed the pulley:
I also decided to modify my original design for the coil/ignitor mount. Istead of using metal spacers a while back I bought a bunch of 1.5" long plastic spacers (3/4" diameter, 1/4" hole). I spent the afternoon cutting six down to 1.25" length and four down to 1" length. End result:
I'm still tweaking the spacers a bit but over all I think I like this better than what I had before.

I was able to finish up the injector plugs over the weekend. I tried to take a picture showing what all I had done:
The bottom of the plug on the left shows how I had to modify them to avoid blocking part of the intake port. You can also see the painted vs. not-painted color difference. It's subtle but I thought the shiny, machined aluminum look wouldn't really fit on my engine. This is the same paint used on the intake manifold, thermostat cover, alternator, and front cover. I also rounded the corners of the retaining plate to give it a more finished look. Little things...

So I was thinking today, "Do I need an oil catch can?" My "crankcase" is vented through the oil filler tube. In the stock setup there is a purge valve that meters the amount of crankcase gaes into the intake. This is also tied into the charcoal cannister via a nipple just below the oil filler tube on the center intermediate plate so the purge valve allows both crankcase gases and fuel vapor back into the intake. The purge valve and nipple on the intermediate plate are both long gone on my setup. Right now I have the vent on the oil filler tube tied back to the charcoal cannister, using it as a sort of vented catch can. My question is should I really be running a separate, dedicated oil catch can and would it be wise(r) to hook this back up to the intake?
I saw that. So you're using a coolant overflow bottle as a vented catch can? That's somewhat similar to what I currently have but I'm using the charcoal canister. I just donth know if it's a good idea to use it or not. I guess it isn't a big deal to have it hooked up to vacuum though?
Okay, but basically the same thing right, and you aren't using any kind of vacuum to assist with crankcase ventilation? How much blow-by oil do you collect? If it's a lot I'll seriously consider getting a separate catch myself. What kind of vacuum line did you use? I've used silicone in the past on the PCV system in my Protege5 and oil seeps through it.
