We hit the track with Flyin' Miata's latest power adder.
This is my first post on this forum, so I thought what better way to start my first post than that of a build thread. So a little over 2 yrs ago I purchased my 94 Miata A Package with 93k on it and lots of hail dents for 2k. I bought the car from the original owner who sort of took care of it.
First things first I freshened up the motor, trans and diff with all new fluids. Cleaned up some stuff and added a Mishimoto radiator. I put in a F1 Stage 3 six puck which was ok but would later fail on me. I also installed Megan EZ Streets which many argue to be a POS coil over but I have had them for about 10k on 2 different miatas and have survived several autox and drift events.
At this point you are beginning to loose patience with me and my build but have faith less fail is to come and more awesome choo choo power goodness.
After bending a NRG steering wheel leaving my apt complex. I learn my lesson and got a 350 mm Monte Carlo.
At the same time I installed a Hard Dog Hardcore Roll bar and added a 5 point G Force Harness.
Then I was bored. I loved driving the miata but Powering through corners on stock power with a knock off Magnaflow muffler wasnt doing it for me. I need something more. So like many I bought a used FMII no electronics kit and began working.
In the middle of a Texas Summer I built my DIYPNP MS2 and Installed my FM2 on 460cc rx 7 injectors. I was ready to lay down the powa! So I thought.
Quickly I realized these little cars hate to have big ass intercoolers placed in front of them and air doesnt enjoy going through them.
More of this would continue to happen and I got fed up and began ducting with plastic roll. I also added a coolant reroute and built my own COP harness.
I pulled a tone of emission crap out and and took out the dead weight broken AC and cleaned up the bay agian. I also added slotted rotors and EBC green pads. As well as a cheap straight pipe exhaust and left my hollow out cat. ( My county doesnt have emissions but checks for a cat).
I went a little crazy on the ebay and bought a lip and put in a GT500 extractor. This is pretty much where I stand.
These are my dogs Torsen :) and She Ra. Torsen is a Rottweiler hound mix and is still a puppy. She ra is a border collie greyhound mix both rescued for the animal shelter
So I added a EBC and with in the matter of a few pulls the clutch was toast.
So I did the right thing and machined the flywheel and got an FM1 clutch kit and began doing my first clutch with my wifes encouragement in my little garage with a little floor jack, two Jack stands and a sizzor jack.

Currently I am breaking in the clutch still and will be installing this as the FM wastgate bracket took a crap and some how has tons of flex and leaks.
It should be here Thursday and Im pretty excited I will be able to service it and it doesnt use that funky bracket that FM uses not that its a bad bracket I just think the guy that I bought the turbo from might have dropped the turbo and the wastgate actuator hit first and broke part of the bracket where it bolts on to the compressor.
Anyways this is my first post and I look forward to being part of the discussions.
Hey, welcome! It looks like you've done some nice work.
I like the looks of that hood vent, but it doesn't look like there is much "meat" holding the nose of the hood on now.
Nice work! Nice dogs, too...
Welcome to the forum!
Welcome. I just picked up a '94 myself.
How many mph is it?

Yeah it is slightly flimzy. It was more of a cheap experiment. I was having overheating issues and ducting was only doing so much. After I installed the extractor overheating is pretty much gone with the wind (see what I did there haha). All I need to do is add some bracing to the underside but I need to figure the best approach to welding connecting rods on the otherside since its all aluminum. The hood was already light to begin with but its insane how light it is now.
UPDATE: I played with the kinugawa wastegate actuator this weekend and it seems to be well built however the ratings are way off. I was hitting 12-14psi on the 2560R with barely any preload. On their site the actuator is rated for 4.5 psi haha thats way off. I took all the pre load out completely and adjusted the positioning a little more and managed to get it down to 10-11 psi. My goal is 12 psi. I am thinking a lot has to do to the wide variety of applications its designed for. Since different turbo have different flow rates. possibly? Idk if my reasoning makes since. I contacted the company about the issue and Im waiting for a response.
I was also having lots of heat soak with my IAT sensor so I relocated it this weekend to the front of the intercooler on the cold side. I figure this will help avoid the underhood heatsoak I get when sitting in traffic or starting the car after being parked for 15 min.
The sensor is already water resistant but I went ahead and added some extra water protection. I went for a drive last night it was about 75 out and I got the temp up to about 185 on my water temp sensor. When I went to park it I was able to touch the IAT sensor and it was cool to the touch. I hope this fixes the heat soak.
I also finally washed the car after doing the clutch swap. Boy was it dirty.
