I kinda dig the ITB/plenum set up in a "this is totally stupid an unecessary and on top of that, is made for a 1.6" sort of way.

I'm still confused ... the reason I want a second hand kit is that the car will be my first self turboing project.
I'm confused about how everyone says "you are only going to use the turbine and the manifold" why on used or new kits I have heard that a lot... If the kit was already in an NA6 and I buy an NA6 then why couldn't I use everything as the guy before me did. Being in Japan I feel comfortable buying second hand also , its not like buying used in Australia where every 3rd bloke is a hoon. Japanese look after shit , I know a lot of guys here tune their cars just for the sake of it ...I have never in my 10 years here heard a tire squeal unless it was done properly at a track or somewhere secluded after midnight etc...lol

It's because the stuff in these kits was largely garbage to begin with. Doesn't matter how well it was cared for.

Which Japanese ECU for Miata then? This turboing stuff the more I read the more confused I am. I guess the hard way will be the best way to learn this stuff.

I don't understand what a "Japanese ECU" is.

No offense, but it's fairly evident that you are no where near ready to be boosting your car. You need to put the wallet away and do some serious research into what you are getting in to.

I would add:

if you don't know EXACTLY what you want, what you plan to do with it, and how you plan to go about making it happen, as well as a thorough understanding of WHY to each of those questions, you don't know enough to turbo your car properly.

Sure, you can "learn the hard way", but I wouldn't like to find out the odds of that vs miserably failing.

I mean aren't there some Japanese brands , Apexi , HKS that make a Miata ECU? I know I have tons to learn people that's the reason why I'm here!

Regardless , this is why I'm going to spend minimum on this car , because I know I'm not ready to be doing it myself , I stated that clearly at the start of the thread.

Thanks for the advice and sorry I have so many annoying noob questions!

To sum it up the only way I can keep this low budget is if I buy all Japanese parts including the ECU because I am in Japan ...

Also Im sure an ECU such as a Megasqurt or an AEM are awesome but I doubt there will be anywhere that can tune those here , 98% of people don't know any Engrish for a start.

I've sent plenty of of MS'es to Japan, HK, EU, and Aus and somehow they all managed.

I think the problem is that WE'RE mostly in the US, and don't use "Japanese ECUs" because we like nice things.

Funny, I lived in Japan for about 15 years and had no problems. Perhaps you should try to assimilate into the culture a bit and make friends with some garages.

In case you haven't noticed yet, we are not about spoon feeding here. All the information you need has been discussed ad nauseum, and is not difficult to find. Like I said before, you aren't ready for this undertaking. Building a turbo car on a budget takes a strong knowledge of what everything does, and what parts are worth the investment.

You lived in Japan for 15 years so are you like 50-60 something?

Friend at the moment I am in charge of the overseas sales of a parts firm in Okinawa from trying to make friends in the car scene its where I'm at so I have connections in a department that I can get those parts next to nothing . Unfortunately tuning is very rare (and age) in the area I live , (furthest South on Okinawa away from all the Americans and that's where the tuners are mostly in their 20's)...

Funnily when you lived in Japan for 15 years ago the Eunos Roadster was relatively new and popular and there was lots more " Roadster mania" as they call it here , was your life like The Fast n Furious Tokyo Drift too? JK

#1You were in the friendliest areas of Crapan if anyone let you mess around their shop and your Japanese must have been great because 97% of people can't speak a word of Engrish there...

#2 Japanese in main land Japan usually frown on any gaijin coming around their shops unless they are interested to get some free Engrish practice (if they are middle aged) or you are ready to drop a few K in their shop. Or again , you are one lucky m.... f..... I lived in Kobe + I got into cars as a serious hobby only recently.
I used to own an RC parts store which was a second job + played live music. Not so lucky like some of you boys who grew up around cars either ...
Year 2014 , there are very few NA , NB Miatas left on this island , mainly NC here and there in my area ...

So for the third time I will tell you ...you were at the right place or definitely the right time.

Oh ...wanna see the tuning car scene in Okinawa in 2014?

Here you go a short documentary by Vice Published on Feb 17, 2014


There is a subtitle captions option there ...Vice is an English speaking company ...see any Japanese speaking English ? NO

In fact do you see any Jap drift or race videos like the old ones with Keichi Tsuchia Option bla bla bla ?
Ever see any Japanese drivers or tuners speaking English in any interviews at all?
Show me the link...???

Don't tell me you went to Japan and made tuner buddies please , I won't say its impossible but , if anyone reads this , remember what I'm saying when you visit Japan yourself!!!
Japan is the opposite of what you imagine ...Japanese people are kind but not friendly and open to talk to any one anywhere like we are.

Few young or old guys including Mighty Car Mods attempted to go there just to make a video of the scene , maybe you have seen them...was there at least one Japanese person speaking and hanging out with the crews ??? Ya get my point ...Japan is not what you imagine.

I'm thinking to start doing video blogs soon ... I wan't to put a camera on one of the busy streets in Japan and let it video all the cars that go by ...out of 200-300 cars you might see a slightly tuned car and its bound to be a Skyline or a Toyota Chaser.

There is a place called Speed Factory close to where I live in Itoman City , I know those guys ...they have been there for years ...many Americans go there etc. They get 90% Nissan Skylines - Chasers they actually helped me out with my Chaser but don't even recommend tuning a Roadster .

There is very little Roadster "Mania" left in Japan...

I can probably put together something out of salvaged parts if someone helped me out ...I'm buying a T25 with a T3 flange out of a RB20DET for $30 in a couple of days ...I can do this super low budget , I just need the help.

If there are no Jap options on an ECU then I can purchase an overseas made ECU ...

Looks like I gottta meet some Turbo Miata owners in Oki and figure something out as for now all I have is two friends who own stock GTR R32s and one who has owned and built Silvias and the 86 Trueno....

He didn't say he lived in Japan 15 years ago, so i'm not sure what that entire post was all about.


If you're hell-bent on using Japanese JDM Ass Fuck ecus, then you should probably definitely make friends with local turbo Miata guys, as here, we use good things and don't worry about where they come from.

In fact, many of the Megasquirts that we use actually come from Greece. Weird, huh?

He lived there for 15 years so my point is it was 15 years ago that he moved there or more ...for fucks sake think

JDM ass-munch ???

Apexi , HKS bla bla bla ... I wont go on with other superior Japanese electronics ...

Oh and one small thing the car we are talking about The Eunos Roadster is a JDM ass fuck car too?
Hmmm maybe its Greek that's why its so reliable :idea:

So it happens not one of the serious ECU makers bothered with the Roadster , so now they are shit?

I'm asking a question ... I had no idea that its only the Trust e-Manage Ultimate that can be used for Roadsters out of Japan...

There is nothing on them on any boards so I didn't know why and its answered by accident finally , I though common sense Japanese car so I expected that there are makers here that had specific models for the Eunos ...now I see there aren't , that's all I was asking for fucks sake ...

Go Google "Japanese ECU/aftermarket computer makers for Mazda Miata MX5 " what do you get? Nothing.

So if I ask "Are there any Japanese ECU's that I can use for this build?"

I get " I don't understand what a "Japanese ECU" is." -

Jesus Hitler Adolf Christ ...if you don't want to answer peoples questions and help out why bother trying with a half arsed effort...go chill , have a beer , maybe someone else will answer an "Are there... ?" question with a yes or a no.

Bet you $20 you didnt even read that long post there and think I'm praising JDM tuning ...go read it before you start bitching off...its to show you how tuning is "not in fashion" here anymore! In general and especially for the MX5

Quality control bot, aisle 9 please.

The point was that he could have lived there as recently as yesterday.


But really, please just go away. Nobody here can give you the help you think you need. As in... nobody is going to tell you what you want to hear.

You don't want our input. You want your own opinions parroted back at you.


And I say this as an HKS fanboi that makes extensive use of their equipment on my daily driver.

Looks like your plans to put an aftermarket JDM computer in a Miata are DoA.

..

So, Aaron, you speak Japanese? That's impressive. Props.

What was this thead about again? Seems kind of DoA.
