It costs $4000-5000 to properly boost a miata for the street.

I've seen kraken's stuff and it's great. But I really want a complete kit personally

Yeah, that's usually including a diff and clutch right?

Just a clutch, because a proper miata will already have a good diff.

$4000-$5000 assuming you're starting with a solid base.

Mine's an NA6 so no Torsen

Time for some basic arithmetic.

MKTurbo $3850
96 Torsen $550
Clutch with flywheel $670
$5070 total
Cooling and brakes have already been taken care of.

Well done, gold star. :)

Good wheels and tires have also been taken care of. Being in the South, cooling was a big one

You can do the clutch for cheaper. I would buy a used 1.8 stock flywheel. Then put on a 949 Organic clutch or a FM1. You can use the 1.6 949 Organic clutch, but I am not positive if it will hold enough torque. I would rather you not have to rebuy parts. That will get the clutch into the $300-$400 range.

1.8 diff is anywhere from $300-$1000. Just depends on luck, timing, and what exactly you want.


I can say when I was working on the price for my full setup. I wanted to make it as cost competitive as possible to what you will end up paying when going the DIY route. After seeing hundreds of builds on mt.net and doing several myself, I found that $3000-$4000 is about what you will end up cost wise on turbo parts to max out a stock motor. You can do it a little cheaper with searching out used parts, but you will be waiting for them to pop up.

This sounds like an excelent plan. On a street car, you can totally skip the lightweight flywheel (a used 1.8 one can be had cheap) and do an open diff for half the cost if you are on a tight budget.

And while the 1.8 is better, I can tell you for sure, a boosted 1.6 miata is nothing to sneeze at and a whole heep of fun. I have been enjoying my stupidcharger for the last 5k miles trouble free and my friend has a heavoly souped up greddy kit on his 1.6 crap can and that is a hoot (especially on 700tw all seasons.).

Yeah, I plan on getting a 1.8 clutch from 949 since it holds almost 300lbtq on it's organic disc, and I found a complete 96 torsen with axles and driveshaft for $550. And I might just go with a stock 1.8 flywheel

MK Turbo got Sonofthehill to 12 second quarter mile times. What is he running, about 15psi?

Damn, that's impressive. But I'd imagine his engine is pretty built

stock engine in STH's car.

For clutch, you could always do an eBay flywheel and 1.6 949 clutch, rated to 220 ft lbs. about to put that combo in my dad's MSM.... will report in my thread how that goes. Totaled $470.

I'd definitely like to hear how that goes! I like to save money where I can, but not cheap out on quality

I haven't been recommending the 1.6 949 clutch just because I'm not sure if my turbo setup will beat that torque limit. The 1.8 I know will hold far more then enough. I f you can stay away from wanting to turn up the boost to much then it will probably work great. If you think you might want to turn up the boost then I don't want you having to buy a second clutch.

I was planning on the 1.8 clutch because of it's greater torque capacity and pairing it with a stock 1.8 flywheel

Since no one else mentioned it, keep a close eye on the classifieds (and facebook). I just picked up a mint FM2 clutch on the dirty. Quality used parts are pretty easy to come by.

I wouldn't recommend SOTH's power as something for a newb to emulate on a stock motor. He had it last as long as he did because he knows how to tune. He was probably in the 280 range with his trap speed.

I know that my motor would have blown a long time ago if I had tried that...

225 is a healthy goal though.

The worst thing about having a turbo kit for a 1.6 is that you'll have to replace it with another 1.6 if/when you blow it. Or you'll need an entirely new setup as well.
