I also made some mild changes in the engine bay. Originally, I only wanted to install the TRD rear strut bar, but being my clumsy self I dropped one of the mounting bolts and it got wedged underneath the OEM airbox. When I pulled out the airbox to get at the bolt, I noticed that one of the clamps was missing and it was actually drawing in air past the air filter. Oops. Time to pull out the airbox and fit my almost complete ARC air intake instead. Those who've seen a build or two of mine know I like ARC parts and tend to snap them up whenever I can. The ARC intake for the 2nd gen engine is actually pretty rare so when one came up on ebay, I grabbed it.
It was missing a couple of bolts and hose clamps, so how bad could it be?
First, I decided I didn't like the OEM nuts that hold the AFM and airhorn together, so I tried to replace them with nyloc nuts.
So far, so good, only that I didn't have short enough wrench so the whole thing got put on hold while I started bidding on some Bluepoint short wrenches on ebay. Getting them took a while but I was finally able to do this:
Hey, only spent $120 to fit a dollar's worth of nuts. Fortunately there's also a K&N filter that's a perfect replacement air filter for the ARC foam filter that was missing from my airbox, resulting in this:
I had to improvise a little more as the little rubber sleeves for the mounts have gone AWOL. The OEM sleeves are too big but will do for now. After yet another trip to Summit Racing to buy some proper, boost safe hose clamps I finally got the whole thing together just in time for the last Club Trials event of the season:
Well, almost. I had noticed a lot of movement in the engine when I was hard on the gas, which didn't exactly improve the shift quality. I ordered some urethane inserts for the front and rear engine mounts to solve the problem. Pulled out the front engine mount and was greeted by this little guy, which really couldn't be persuaded to take the urethane insert.
Yep, someone had fitted an N/A MR2 front mount to a turbo. Given some of the other mods that I've discovered while working on the car (for example, the center tunnel cover has been wrapped in leatherette and I think the seats may have been dyed), I'm guessing that someone wanted to turn it into a more "luxurious" car. Didn't help me one bit, but thanks to one awesome vendor on MR2OC, I had a used turbo engine mount within a few days and ended up putting the urethane insert in the day before going to the track.
After bolting on the OEM wheels with BFG Rivals, time to head for the track. The first day wasn't that successful as I was consistently 2-3s/lap slower than in the rented Spec Pinata I used for the previous event. After some tweaking of the suspension (turns out the front Konis hadn't been set consistently) and bumping up the tire pressure to 34/36 from the 26ish/29ish I run on the street, I finally managed to get consistent lap times and broke the psychologically important (well, to me) 1:40 mark on Thunderhill West:

Over the season this year I managed to find almost 10s/lap when I compared to where I started out. That's pretty good in my book. Plus, I'm not last in my class anymore . Given that this was my first season doing actual competitive motorsports, I'd call that a result.
With the season over I know have to figure out if I want to throw more mods at this car (mainly suspension, but some additional power mods). I've never completely warmed to it, plus it's got one big downside that already cost me a couple of track days - try transporting a second set of wheels and all the equipment to change tires at the track without trailering the thing. Something more hatchbacky (and with better parts support) might be the way to go unless I really want to drive through snow storms on well worn Rivals.
