i think it’s too low temperature. The coolant goes to 80C in a decent amount of time but oil lags behind a lot. Let’s see how the 90C thermostat goes.





Dang Nate, that’s emotional, but full of truth. This forum is awesome (I’ve been wanting to use that for too long haha). In all seriousness, the knowledge sharing and help given is truly great around here.

I’m down to do PPRI as pit crew or to spectate. The 1k driver entry fee is rough for me this year.

Im down for pit crew or to spectate! Let’s hash out a plan soon.

You guys should consider the trip to Miatas at The Gap. The MT.net group there every year is tight and supportive in the same way. We also often exchange items that are too heavy to ship easily, not just for ourselves but for others back home who couldn't make the trip. We even had Gemlingz there from Iceland a couple of years ago. He drove all the way there...

Oh f*ck, entry is a grand? I’m not gonna have that much money to my name after this drivetrain swap I’m still down to run it if you guys are. PM me your number and I’ll start a group chat this week!

My science teacher told me the land bridge disappeared years ago. I knew she was full of it!

Driving to the east coast trailering the car would be kinda f*cked from where I live but maybe one of these years I could fly and convince the girlfriend that we’re going on an east coast vacay lol. It’s on the bucket list for sure. Looks like a good time.

OK, count me out at that cost too. Maybe we could all just do a trackday in Arizona and meet in the middle or something.

Ricardo, let me know if you need a hand with swapping that new engine in or anything!

Z_WAAAAAZ

Yeah, agreed, it might be better to meet in the middle and do an event that doesn't cost an arm and a leg.

I hear Arizona is a great place to visit in the summer I'll stay in touch.

If you need some extra heat in your engine you're welcome to borrow some of mine. I've got more than enough.

Definitely jealous of you guys have access to multiple tracks... Maybe I need to get a truck that can actually tow.

Always tow so you always get home.

Honestly, I'll take a little extra heat. My cooling system is overkill when driving on the street in the winter. My record this year was running 30 degrees under thermostat temp on the freeway lol. I need to make a removable radiator block off panel. It's perfect for running hot laps in 90 degree weather @ ~270whp though.

Seconded. Having now towed my vehicle for the last year, it scares me to think I used to drive it 5 hours round trip to race it with a turbo'd 200k+ mile stock motor lol. I think even when I blew my last 6 speed, there's a good chance I could have made it home. I'm glad I didn't have to find out though.

I would be down once I get a trailer setup figured out! That way I have a chance to survive the scorching heat.

I'll take it, especially if it helps you too haha.

Absolutely. Now that I've got a taste of towing, I really want my own. I'm sure one of these days it'll be the only way to get the Miata home...

I decided to upload the video of the last trackday when I was mentally checked out and played with adding some more telemetry:



The last two weeks have been anxiety inducing. I've been preparing to swap a BP-6D in Scooter, and I also wanted to do a 6-speed swap while I had all of it out. Unfortunately, the tail housing was damaged in shipping. Zak has been awesome and sent me TWO tail housings, one NB1, one NB2, yet neither worked. This housing I have has a boss for a detent, which after talking with Flyin' Miata, Mazda Motorsports and @Fireindc , seems to be a non-USDM thing. If any of you know more, please let me know. I asked the shop to put the trans back together with one of Zak's tail housings anyways but I knew I wouldn't get it back in time for the swap as I want to make it to FM Summer Camp in June.

No detent on this one

In the meantime I decided to swap from 500cc injectors, to 365cc. When I chose these 550cc injectors I knew they were way overkill but I couldn't find anything smaller with ECU data. I also didn't realize how much that would affect idle and low throttle cruising in an NA application. I went with FIC 365H and they provided injector data for the Link ECU. Some re-tuning was needed around the low TPS cruise and idle areas but it all worked. These injectors should also support E85 at my future power goal of around 160whp.

I then took Scooter on a few cruises throughout the week to give the BP-4W a final send off. Lots of fun was had.


I love hanging out at this lookout, if you can't tell



I should record this drive sometime but it's not easy to make it justice. Maybe telemetry or an engine bay mic would help with that

That brings us to yesterday. A day I've dreaded for too long....








Having friends around is always awesome





So the BP-4W is out and sitting in my tiny garage. This is the first time I pull a motor and it's a bit surreal. Today I'll spend all day cleaning and finishing the BP-6D and hope to introduce Scooter to it on Sunday. I don't expect to start it until later in the week because some wiring needs to be redone (cam sensor, R8 coil swap, Link CAN Lambda). I'll also post more pictures of the ITB linkage and BP-6D later when cleaning is over. Wish me luck.
