No flame, genuine compliment. You nailed all the power limits, even the 5-speed's dependency on being nice to it. Either you're making very lucky guesses or you did your homework.

The '03 has the crappy TF diff, which is different from every other 1.8 diff out there. They aren't known to be as reliable as the Torsens so just keep that in mind.

The 6-speed is way, way stronger than the shitty 5-speed. The 5-speed has been around since the late 70s in Mazda and Ford trucks - the 6-speed is a much newer Aisin AZ6 box. The same gearbox (with different bellhousing/tailshaft) came in the JDM IS200 6-speed, as well as the S15 Silvia. The Silvia guys typically start to break the transmissions starting at ~325-350whp, with increased transmission as you start turning the power up.

The 6-speed should hold up to ~350whp reliably in the Miata. The 5-speed will cry uncle at ~250 eventually.

I do want to add that the 03 miata's that were 5 speeds came with a torsen, not a TF which iirc is the tifigi Fugili or w/e...... My point is the 6 Speeds in 03 came with the viscus diff where as the 5 speeds came with the same tosen as any of the older models, but had to be a "checked" option.... This is at least what i have found out, I'm not saying it is truth as i only have opinions online to support my statement, but it could make sense. I believe your talking about the Viscus variable fluid diff, but that is from what i have learned THUS far is NOT in mine as it was a original 5 speed, and has the sport brakes but not the 6 speed, has the bose and the silver trim, but not anti lock brakes, nor does it have sport springs, from what i have herd they look like when i swapped my cheap ones im running now in there..... Anyways, I would like to thank you for your genuine compliment as it means a lot..... since most of the people only refer to Miata turbo as the intelligent but flamer group......

Anyways, i really want to thank you guys for the help and please let me know about being able to swap MS2 from parallel to stand alone!

There's no need to swap it from parallel to standalone - if you swap it, just swap the stock ECU back in. The point of parallel would be to not touch it ever - you still retain full control of fuel, spark, etc. but you leave idle, emissions, etc. with the stock ECU.

It's not piggyback where you modify stock signals - it's parallel, where you make your own signals for some stuff and leave some stuff alone.

It takes 5 minutes to swap ECUs as my Megasquirts are fully plug and play. Injectors, it takes what, 1 hour? I mean, it takes more time to give your car a decent wash and detailing.

You are sexy noob.

My only input is to aim for as much power as possible and get a turbo manifold and downpipe on day one that can support all that power. More power is more fun. That's about it.

I dont know how i feel as i know your a dude, and so am i.... so i mean, ill take my car is sexy, but yeah.....

I will start looking into what the power level limits of the Exhaust mani of the FM II kit that comes with just hardware will go, as i do want to have headroom past 250, just for the sake of it, along with a intercooler that will allow that as well. The Intake mani, i will have to look into as well, maybe gut it, just for now, and later get a expensive one, as it seems no one has a lot of evidence about one intake mani being better than another.

On a side note, has anyone built a DIY intake mani and had good to great success with it? any links or someone i could contact to ask about it? thanks guys!

Falcon is running an IM that another member on this site made. He runs a rotrex and whatnot, bu in this thread https://www.miataturbo.net/showthrea...=rotrex&page=2 you can see the difference in torque up top.

Mind that this is a NA though.

Ok, so as i get closer to parting what all i need togeather i have another question. The turbo size, after looking and thinking hard, i want a little bit of lag so i can still use liberal amount of throttle going into turn but by Apex or so be able to claw out of the turn with boost.... Its kinda how i drive, but what im more asking is, if a 2550 will be similar to a SC, what will have a little more "*****" to it, and have JUST a little lag....if that makes sense....... kinda of hoping someone knows of a good turbo a couple sizes up from the 2550 but isnt like 5K before i get boost... Also i know that this is a lose guess as many things can effect that BUT i still need good idea?


Thanks again for all the help guys!

There are only so many options. 2860, 2871 are next sizes up.
