Turbocharging/Supercharging NB with automatic transmission
 

Owning a 2004 1.8 NB with auto tranny.
Miata is an-anti stress toy, but need more power to take away this stress much quicker and get more fun :fawk:

Was looking to make a swap of engine from MSM, because it has:

Factory supercharged egine
Manual Transmission
LSD


But after reading this thread ( [NB] Mazdaspeed swap (into '02) - MX-5 Miata Forum ) understood that this is not a good idea at all.
Turbocharging/Supercharging would be better in my case.But i would prefer Turbocharging as i really find supercharger noise annoying.

The question is, any of you guys had an experience or any info on turbocharging of an NB with auto transmission?
Any mods must be made with transmission before going on with turbo?

Would be glad to get some threads and articles to read and get useful advices.

oh my.............:facepalm:
don't even know where to start

in for eggplant

Just start, and we`ll see :)

But please do not advice to sell AT and buy MT one.My Miata is the only one Miata in our country.And due to law limitations there is no possibility to import another one to our country :) Thats why I`m thinking on such crazy things ))

The main goal is to have a daily driven auto, which will be very fun to drive

ahahaha do what ? )))

it...

Thought i could get some advices and help from you before I do it, but it seems like i was wrong thinking so...

in what universe is a MSM supercharged?

I was going to make fun of you but looks like you're from some 3rd world country, so there's probably a language barrier, among other things.

So here's a serious answer:

there are plenty of turbo and supercharged auto miata's. they tend to hold 200-250whp just like the manual ones.

So turbocharge it.

What i don't get is... if doing a manual transmission swap is out of the question, then how on earth is an MSM motor/rear end swap even a possibility?

MSM is a Turbocharged one :) I do know this.
200-250 without transmission mod?And even without AT fluid cooling?

Well, I tried to find out list of pieces for AT to MT swap, so I could order them from USA.But unfortunately could not find any info on it. I case of MSM swap, technically it is much easier, as I could just buy a damaged MSM from auction and move all the stuff from MSM to my Miata.
But as I told at the beginning of this thread, swaping to MSM has some disadvantages like VVTi lose and etc.

That is why I begin thinking on turbocharging my Miata.Was worried, if auto transmission will be able to handle about 200-240 HP.But as 18psi told, auto tranny will handle this power with no probs

At first, I read it the same way. Now, I think he is saying he cannot swap entire car, but he can swap parts.

Vlad, is the stock auto transmission control separate from the ECU? Or will the aftermarket ECU have to control the transmission?

AT to MT swap is easy.

But you said you couldn't do it because you had the only miata in your country. But this means there wouldn't be an MSM in your country either.

I don't know, i'm confused.

Personally, i'd go for the MT conversion FIRST, unless you've had some horrible accident that left you with only one leg that you haven't told us about.

Exactly

I can order a salvage MSM from USA and import to our country as spare parts, not like a complete car

Automatic transmission control unit is separate from ECU.
Decided to use MegasquirtPNP Pro as an engine management.
Gonna use 2003-05 Voodoo II turbo system(without their fuel management)
Gents, any advices on injectors?
thinking on using 350cc injectors.
Should they be enough?

If you are using a megasquirt there is no real downside to getting MUCH larger injectors.

IF

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?

*COUGH* *COUGH*

<<<<turbo'ed a AT

The AT computer is indeed separate, I ran a MSPNP just fine.


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
