At the urging of Psyber, I've decided it is time to start a build thread. I bought my first Miata in 2008. It was a 1990 Miata with a ton of miles on it that I got for $1500. That car is the one that has transformed into the car I am driving today. I swapped the 1.6 out to a 1.8, added a MS1 and a turbo kit made by WittyWorks that I found on craigslist. I drove the car around like that for a couple of years making 223whp/182tq. It was a lot of fun, but I wanted ALL OF IT. I sent a spare 1.8 to get built, and while the motor was at the shop I found evidence that the chassis I was using had been rear ended pretty bad in the past. I decided I didn't want to waste any more time on that chassis and started looking for a new shell. I found a 1993 LE that was being parted and bought the shell and a lot of extra parts for $500. Here is the shell after being pressure washed the day I got it.

I got the motor back from the machine shop, and the work began.

When my friend and I finished putting the car together I took it to a shop for a tune and made 305whp/225tq.


It was a ton of fun, but I got an opportunity to purchase a full turbo kit using an EFR 6758 with only 80 miles on it for $2500. I got the kit, installed it, and started ironing out the issues I still had remaining from putting the car together originally.

I currently only have one issue left that I am trying to solve. When my car is idling and the fans kick on it will occasionally kill the car. I've messed with the fan settings a little bit to try to remedy this, but haven't been able to fully solve the problem. I am going to tinker with the idle settings today to see if I can get the car to stay alive. The car is scheduled for a new tune on Thursday, so if I can't figure it out, hopefully they can help.

As the car sits right now these are the basic modifications I have done. I'm sure I will forget some things:

Whalecum! I think we follow each other on Instagram! Build is looking solid thus far. Have you had any issues so far with the Begi intake manifold?

I've had nothing but issues with it. I've sent it back to get fixed 2 times and when I originally received it the flange hadn't been machined for the injectors to fit. It's been a little ridiculous. They keep blaming it on my AWR mounts, but continue to fix it for free. I won't be purchasing anything from them again.

YAY!

Did you have rail fitment issues with the ID1000 and the FM rail? Mine's tweaked a bit as though it couldn't compress all the way. Turns out I probably should have ordered the flowforce spacers.

I have the FM rail and ID1000s with zero fitment issues once I used the little plastic OEM rail spacers. The ID1000s have a spring spacer deal that compresses as pressure is placed on the rail.

Not the older ID1000's, the x's are the new hotness which you may have. Theres been a revision to those adapters, but back when I had first got these in 2013/14, these ev14's stood a bit taller and the FM rail has tighter clearances on the orings than the OEM fuel rail. I couldn't get away with the slight shift as easily with the new rail in place. It's on there now, So far no leaking, but I haven't played with bumping fuel pressure. I'll revisit it and probably change the injectors out altogether when I finish my new spare head and inspect the motor.

I have recent non-x ID1000s and they have the spring spacer (still longer than the new x injectors though).

I had to get longer bolts, and they didn't rest flush on the oem spacers. Maybe FM's batch of rails didn't drill the counterbore far enough. They replaced the original one I had on hand due to a defect that posed a safety risk.
Anyway, I'll stop cluttering the build thread.

OP: Let us know if you get the idle stuff sorted out. Looking forward to numbers!

Nice PNW build. I'm down in portland and hopefully finishing up my 6758 setup also.

Has it seen a dyno?

alienmiata1

iTrader: (2)

Not with the EFR. That's coming Thursday. Hoping to see 350-400whp

Hit me up! Always down to meet miata people! I'm going to try to hit an AutoX down there this year, so I'll let you know if I bring the car your way

The FM fan kit you have can draw a lot of power. I would try to make em kick on independently. This is a sweet built. What BOV are you using?

psyber_0ptix

Looks like a turbosmart kompact shorty dual port. I run the same. creates a cool helmholz whistle at about 0psi

I do have the kicking independently. I've tried bumping up my idle. It seems they just want to kill my car.

good eye Psyber, it is a turbosmart

Are you increasing idle when the fans come on?

****, my idle up duty is like 7%

Im running on bandaids apparently
