You get the right injectors

I'm sure a quick know search of the forum will point you in the right direction on that particular topic. Your avaliable fuel will also play a role in you injector selection. Where are you located? Do you have access to 91 or 93+ octane unleaded? E85 maybe? You may wish to consider putting a fuel pump on that shopping list as well. You will of course be running a wideband, yes?
Well, surfing a little bit the forum, found that RX8 450cc fuel injectors would be fine(Besides, Pen2_the_penguin does reccomend RX7 460cc injectors as well).
I do have access to 95-98 octane uneladed, no e85 :(
255 Wallbro allready installed and running.
Of course, wideband will be used.

Just get some RX-7 460s, walbro 225, and call it a day.


BUT from my experience, the AT doesn't handle 16+ psi very well in the first gear clutch pack, tends to slip-- i recommend doing a 5-speed swap
Cool.Did you use MSPNP Pro?
Going to run near 8 psi.
User 18psi told that if not to abuse it too much, factory transmission will handle 200-230 whp with no probs.

Azerbaijan. And for the folks playing along at home who don't know where or what that is, it is a central European country that was a republic (SSR) in the USSR until it declared independence in 1991, shortly before the USSR dissolved. (As to the comment about the OP being from "some third world country," when it was part of the USSR it was technically a second world country, since the division of the world into three parts (something Julius Caesar started when he began his book "The Punic Wars" with "All Gaul is divided into three parts ..." (well, as I'm sure we all learned when studying Latin in high school, he actually begins the book "Gallia est omnis divisa in partes tres, quarum unam incolunt Belgae, aliam Aquitani, tertiam qui ipsorum lingua Celtae, nostra Galli appellantur.") was first world = industrialized western countries; second world = industrialized Soviet bloc countries; and third world = less/non industrialized countries. BTW, any guesses as to which of the three "worlds" invented this division? )

And the country is developing a road racing tradition; see: Baku street track set to host Azerbaijan’s first GP in 2016 is unveiled | Sky Sports

I was wondering about fuel, too, but if the OP is running an '04 Miata, and the country is hosting a Formula One GP, then there must be relatively high octane gas available. There may not be another Miata in the country, but I expect there are a number of high dollar European and Japanese sedans and SUVs that need to be fed and kept happy.

Bill (who really did take Latin in high school; of course, the language wasn't quite as dead then as it is now. We had toga parties long before anyone heard of John Belushi, and Animal House was not even a thought, much less a movie.)

All respect to Jeremy, but stay away from the RX7 units as they are oldschool Bosch EV1 technology from like the 70's. The RX8 injectors are a great budget choice as they are a much more modern design. The new hotness is the Bosch EV14 technology as found in Injector Dynamics or Fuel Injector Clinic injectors. That should give you some direction to read up on.

18psi is Russian, I'm sure he understands. TBH, I was expecting something random like Sumatra or Nambia or whatever. Having "the only miata in the country" is a little hard to wrap ones head around.

And thats totally cool, but remember, I have no idea what kind of fuel is available in Sumatra

That's bitchin. I love motorsport but I grew up with Laguna Seca in my back yard so I'm a little spoiled.

I'm super interested to see where this is all going. Are you going to start a build thread somewhere?

Great, will look for RX8 ones

I can start a thread about racing events.The closest one is Baku City Challenge 2014, which will take place on 1-2th of november.
I will be in staff crew in the place, where those races will take place, so a lot of photoes can be made directly from workshops and garages

I`m a little bit confused, as Flyinmiata.com says :

"Q: I have a 96 Miata (1.8L Automatic). Can this engine and trans configuration handle a turbo? If so, at what boost and what HP at the rear wheels without destroying the trans or engine?
There are a few automatic Miatas with turbos running around and they are not having any transmission problems. You may also need to modify the downpipe slightly to clear the larger bellhousing of the automatic. For your 1994-05 automatic car you will need to buy a Voodoo. Our FM II will not work on the 1994-05 automatic cars because the FM II replaces the factory ECU. The factory ECU operates the automatic transmission on the 1.8 and our ECU does not. 1990-93 cars can use the Link or Hydra ECUs if desired."

Please comment on it

It appears FM is saying the ECU does not operate 1.6's with autos, but it does in the 1.8 cars. What year car did you turbo Pen2?

Noticed transmission Control Module on page 6.
So in case of 1.8, ECU is not messing up with transmission, right?

Looks like it still has a separate control module. No idea what FM is talking about.

I have a 1.8L 94' miata, and the module is indeed separate.


As for RX7 red tops, I will admit i had to make a low-impudence resistor pack for my injector harness, but ive havent had issues. RX8s are plug n play though

Thank you, everyone for being nice to Ahmad. I'm certain he is in a difficult position having only one of three Miatas in the city of Baku (please reference his "Meet and Greet" thread from last week). Many of us are spoiled by having so many Miatas and so many cheap resources in our own language. And thanks to Bill for being extra nice.

Please continue.

I was running 15psi on my auto NB... ran all of it when the boost controller went out. That's the reason all 4 rods got bent and cracked the ring land of #4.
BUT the auto trans never puked, even though it had 220k on it. It was rather odd though, it also would wind out a bit before shifting. It was nice sipping coffee in traffic then get on it when I needed.
Did conversion to 6spd now.

About 9 months, tracked it twice at Barber. Honestly, I had planned to do the 6spd swap expecting the trans to blow. Engine went first. I had it tuned at 225ish.
The "odd" thing mentioned was it losing power in the converter - just like a slipping clutch that slowly engages - but all the time.
I "heard" that the miata auto is the same as in the fd autos - truth? I never researched it as I didn't care.

im not sure about the FD autos, BUT it is INDEED the same automatic transmission used in 1980s 300ZX turbos. I was able to get a boost referenced vacuum shift modulator from one and it created better shifting.

here is a old video of a 0-60mph in my turbo auto

Cool,

My Miata shifts on 5500 rpms, how did you make shifting on 7000 ?

Tranny ECU Tuning?

Nissan 300ZX turbo boost referenced, and adjustable vacuum shift modulator, its like a 12 dollar part that you just replace the oem shift modulator with.
