I picked up a few interiors pieces for the Miata, those parts were Aerodramatics door handles, I.L. Motorsport door cups, Zoom type 2 radio console, and Zoom type 2 center console.

My oil and coolant temp gauges had been sitting on the passenger side floor for a while and I finally wanted to mount them, so I worked on installing the zoom radio and center console. While I was there, I installed some other parts that I had also been holding on to such as AWD vent rings, K.G. Works vent *****, AWD cigarrete lighter surround ring, K.G. Works climate control lever caps, Zoom push to start button, and RevLimiter window switches.

Thanks. I still have plenty of things I want to do to it. The pics will slowly start populating this thread

Got my K.G. Works rear view mirror installed. Also installed I.L. Motorsport door cups with AeroDramatics door handles, and RevLimiter leather door straps.

This past weekend, I installed a TSE radiator that I purchased to help with coolant temps. I don't have a lot of miles on it yet, but so far my initial observations are that coolant temps were about 10-15 degrees cooler while cruising on the freeway. I was also able to switch back to a stock cooling fan. Now I don't have to worry about the Spal fan pulling a lot of amperage during start up. I burped the coolant system with one of those Lisle funnels and it worked great. I did have to cut my top radiator hose that I use with my coolant reroute, but it wasn't a problem. Overall, I'm happy with this radiator, and it'll only be better once I finish ducting the heat exchangers.

I feel the same way about my TSE radiator. It is just a step above everything else on the market. The only thing I would change would be to add a drain plug.

Saw this car in person yesterday - very nice build. Looks good inside and out. It was good to meet you man, hopefully will see you at MRLS in fall.

Having a love hate relationship with that center consol. I like the gauge location, reminds me of my old subie, but something about it..........


That trackspeed radiator looks ultra clean. Mine hasn't even been filled yet and it looks like that vanity plate up top is oxidizing and needs a polish. Probably won't but nothing is pretty on the car, even if unused. oh well....


any new developments?

I love the center console, gives the interior a complete different look, also it hold my gauges in a good location where I don't have to look down very far while driving.

The TSE radiator is still working great keeping my water temps in check and looks good. Not as shiny as when I first installed it, but it doesn't bother me much.

I had been out of state for work from Nov. 2017 to April 2018. I'm back in California now and will continue to update this thread. I've acquired more parts for the car that need to be installed and have plenty more pictures to upload. I also just recently bought myself a 2013 Mazaspeed 3. This will be my new daily driver so I can focus on the Miata build.

The build will continue

What's up everyone, it's been a while since I updated this thread. I recently went back to school and that has taken a lot of my free time to be able to wrench on this car. I also bought a newer MS3, so I parked the Miata in the garage and didn't move it for a little over three months. Summer school ended a few weeks ago and I decided it was time to work on the Miata during the short break before fall semester began.

So before parking the Miata in the garage, I noticed it was starting to smoke when I was sitting at a red light or when I was in slow stop and go traffic. I did a leak down and compression test and numbers weren't that bad. I forget where I wrote down the results of those tests, but I remember it having decent compression on cylinder 1-3, cylinder 4 was around 12 psi lower than 3, and it had about 10 percent leak down in cylinder 4 also. I assumed from the start that it was bad valve stem seals. I had originally used the valve stem seals that 949 Racing sells https://supermiata.com/Supermiata--v...s-miata-1.aspx they were fine at first, but slowly developed a leak that allowed the oil to get into the combustion chamber. Another problem I was having was that I would have low oil pressure during idle once fully warmed up. It is around 10-13 psi on a built VVT motor with a VVT Street/Strip boundary engineering oil pump. I thought the oil relief valve might've been stuck so I planned to replace with a new pump. For this to be fixed it would be much easier to just pull the engine/transmission again so that's what I did.

Rolled the car out to the driveway and pressure washed the sub frame to get all the gunk off.

Got the engine onto the engine stand and started the disassembly. I forgot to take pictures of the exhaust ports on the head, but you could clearly see that cylinder 3 and 4 had oil in them which convinced me the smoking came from bad valve stem seals.

Degreased and washed the block making sure to get brushes into the oil galleys and coolant ports.

Setup a clean table to start disassembling the head. I was going to be installing brand new fel pro valve stem seals, but first I was going to clean everything up. I pulled out the SUB lifters, Supertech dual valve springs, and supertech valves which were covered in hard crunchy oil.

Once the head was fully disassembled, I made sure to remove any old gasket material and I washed and degreased it. I also clean up the combustion chambers and ports the best that I could. For the valves I ended up having to use a bench grinder with a wire wheel to clean up the them. The oil on there was so baked on the valves that no amount of scrubbing with wire brushes would remove it. The bench grinder took care of that in a couple minutes each valve. Once they were all clean, I installed the new valve stem seals onto the bare head and began reassembly. It came out looking pretty clean again once it was finished.

Next, I worked on getting the crank and rod/pistons onto the block. The old ACL race bearings didn't look bad, but I thought if I'm opening up this engine, might as well put in new bearings, so that's what I did. Installed the crank with new STD ACL race bearing and a OEM Mazda thrust washer. I also cleaned up the supertech pistons and put on new Wiseco rings. I ended up setting my ring gaps as follows, top rings .017" and 2nd ring .019". My main bearing clearances were all between .0017"-.0020" and rod bearing clearances were all .0020". I also ended up removing the oil squirters and plugged up the holes to see if it helps with my low oil pressure at idle.
