I would have to go back and look specifically, but I would say I ordered first week in November and got my stuff second week in January? Well worth the wait, honestly.

BUT, Stefan from Napp Motorsports came over and we figured out it was, indeed, the starter and put my old 94 starter in and built oil initial oil pressure! Super happy! Also got notification the FlowForce R8 coils shipped and will be here next week, much sooner than I expected!

next up:
- figure out wideband signal (not reading on MS3)
- take out external fuel pump and new filter
- clutch line is leaking, will swap in a braided line
- first start??



Cranking, no oil pressure

What WBO2 do you have? I'm a big fan of using CAN for wideband communication if it's an option

AEM 30-4100 a little bit older but was used on my last setup and is already installed and wired — I like the can gauges too, especially the multi display ones, but not in the budget for now

Braided clutch line from FM will be here Friday,



Pulled out that external pump, put in a new filter

Looking more like a car!

so hoping to get the wideband communication figured out if I have a free hour the next couple days and get the clutch line in and bled over the weekend


and then first start and break-in? I have a week off of work after next week, was kind of shooting for that then, but I’m a little ahead of schedule at this point so we will see! Weather in Rochester seems to be starting to break into spring too, so I’m happy with this

Can't wait to see this build finished up. I'll be running a 6758 on my build too. Slowly acquiring parts right now and researching. Great work so far!

Got the wideband reading correctly!

Went to put on the new braided clutch line and couldn’t get it out of the old slave cylinder - so after about 3 minutes of messing with that I just ordered a new one 🤷🏽‍♂️

so while I wait for that, I at least got the truck out of winter hibernation


81 C10 350 w/4 speed stick. 1 owner, my dad bought it new and passed away in 2013 so I dropped a new crate 350 in and slammed it. Still technically in his name

it’s kinda of ratty and I love it as just a nice day cruiser

But right on target for the miata first start and break-in next weekend 🤞🏻

Why go dw instead of ff?

I was waiting for someone to bring it up -- honestly, because when I told my wife what I wanted I hadn't heard of any "problems" with them and they were a Christmas gift, seems to be pretty much only in the miata community (these forums in particular) that DW are looked down on. With that said, my understanding is that the 1000ccs are the newer ev14 design and either way are likely a big upgrade over the yellow 440s I had that I can't confirm their origin and were tapping out around 210whp

I also hope to have a decent experience to maybe provide some anecdotal evidence as a legitimate option. That said, Nigel is awesome at flowforce and if these DW's are introducing any kind of problem, I'll just buy FF's and sell the DWs cheap locally. It's not like they are welded in and I can never swap them out.

TL/DR: I ain't scared

YOU GUYS!

Managed a successful first start and break-in

Did a hot oil change and then went out on a short maiden voyage! I was so excited and forgot to take a log, but a huge milestone! A few little things to take care of, but can go forward with road break in 👍🏻


After 30 minutes of 2k rpm break in

Moving under its own power, kinda like the no hood look

Made it around my block, almost four miles. There’s a driveline or wheel vibration somewhere, not awful, but present

Cranked it without plugs and got oil pressure again first, then put them in and it seriously fired RIGHT up, it kinda scared me at first — I wasn’t ready for it haha

stoked though, ITS ALIVE

That’s great news. How exciting. The fun part happens soon. What are you doing for a tune/tuner? When are the dyno runs?

Following what my engine builder said to do, but now something like 250 miles of high vacuum and varied rpms, another oil change, and then to our local dyno guy — if the weather holds out and they don’t salt the roads I would love to get on the rollers within 2 weeks. Probably going to just tune 93 this time and go back with ethanol after more of a shakedown

Congrats on a good first start. How're you handling break in without a tune? Are you just staying out of boost the best you can or did you go the route of wiring the wastegate open?

It's going to be interesting seeing the difference in this car and Stefan's 7163 K24z3. I saw he also got his running this weekend. Both should be rippers.

not sure what you mean -- using the MS3 basemap and scaled my fuel and spark tables accordingly with my tuners guidance keeping things very conservative. He also said to tip into boost and not be too afraid of it, as little amounts of boost followed by the high vacuum is good for the rings

we literally had ours running within 2 minutes of eachother -- big moves in the Rochester miata scene hahah! He is going to the same dyno and tuner this saturday, I am guessing he comes in around 350-360whp on pump gas on that dyno

YOU AND ME BOTH! I think he will destroy one first -- I am content with 5th gear only pulls and is only a street car, something something mechanical empathy... but time will tell!!

Went on another cruise today, put about 20 miles on -- I tried to attach a log but it wont work for some reason? I did upload my tune and would love for someone knowledgeable to just check it over

The car seems to be getting kind of hot, not sure what is going on but I am seeing temperatures hovering around 200 going up to 206 before I got home. Fans are coming on, I do have the supermiata reroute which I think comes with 195 thermostat... but it just seemed warmer than I have heard others saying. Air temp was about 70

fuel pressure regulator is showing 60psi right now (do I change any settings for this over the base 43psi?)

*edit* it looks like the two logs did upload? Car shut off a couple times
