Some stuff has been happening lately...
-My super expensive ceramic bearing exploded after 20 minutes of use but Boca Bearings refunded me and told me to call one of their engineers next time for assistance on selecting the right bearing. Good company.
-Got a squaretop
-Installed my Jongblood 15x9 wheels and xida's
-Went to the track and was seemingly down on power all day. Still tied my personal best (within 1/10th) while being 5mph slower at the end of the long straightaway. So xidas and big wheels make the car grip pretty well.
Did compression check after the track day- sad trombone:
Already ordered a nice VVT engine from parts group. Hack job engine swap coming soon

Car is running/driving nicely. Pretty happy with how easy this was for my first motor swap.
Just FYI for those swapping NB2 motors into NA's:
I did ZERO wiring to put this motor in the car... Made some ghetto mounts for my coilpacks, trimmed the plug wires and am running the old style CAS for now. I'm not running VVT until I get motivated to spend money on VVT tuner thing and do some wiring. I made a plug on a lathe at work to cap the new cam-sensor hole for the temporary.

Car is running AWESOME. Did a personal best at HPR- 2:04.69 I think about 5 sec under SM record on worn NT-01's.
Zero overheating issues with BP6D and reroute.

thanks- I've actually been feeling like I need to move the seat up a bit- and hearing someone else (with lots of experience) say it helps convince me.
I was worried that my legs would be too cramped though- the pedal reach is perfect right now. Might have to buy a pre-made mount with a million holes that I can play around with.

I'd also like to see data on your videos.

I'd like to keep the stock wheel- more stock=better for me and I'm too cheap to pay for one.
How do you do data? I have Harry's lap timer, but use go-pro for video. I'm up to 121mph on that back straight

I'm capturing vid and data with an iPod and external GPS.

A side-"benefit" of my mounting location is that Emilio can't see my hands (actually, that's not a "benefit" at all -- since I can't either -- I end up relying upon other instructors observing).

The car is looking good.
RE: the brake dust, I have found a plastic kitchen scrubbie to be the tool of choice to get that stuff off. It takes a while especially in the corners, but it should eventually come off.
I gave up on worrying about corrosive brake dust for track days when I realized since I store my wheels indoors, I'm washing and inspecting the wheels after every event regardless, so it doesn't matter. I've used the Hawks and liked them in the front but they don't have a DTC-60 specifically for the sport rears. I use Cobalts now. They fit properly, they don't really care about bedding or previous transfer layers, and they work.

Been working on the car more- mostly to fix little things that have been bothering me for a while.
Also ordered a Marrad seat to hopefully make DD'ing a little more comfortable.
Made (bent a rectangle of aluminum) a block-off plate to cover part of the radiator and oil cooler. I've been having trouble getting up to temp on cool days (street driving) and if I run the heater- forgetaboutit. Might have to cover more area, but this was too easy not to try.
Made a Hornetball style cowl intake filter using a hot glue gun :like cat:
Also got some used OEM 16" wheels. I needed a spare or 2 to fit over my big brakes and now I might start running them at the track. Ultimate sleeper miata? They make Bridgestone Potenza RE71R's in this size...
