So I came across a Garrett GT1446 from a 1.4L dodge dart. I have a NA6 which I'm considering going turbo. With this set up, I'm assuming i'll hit full boost at very low RPMs but would it chock the exhaust at high RPMs due too the turbo's small size? I would like to get your guy's opinion on this set up.

Don't do it. Bad idea for many reasons.

This turbo was well matched to our 0.45L FSAE car.

Use it as a cup holder or something and get yourself a cheap SR20 turbo for cheap.

Can you get another one just like it?

I like the way Joe thinks....

What would be the smallest turbo you would put on a 1.6L?.. I'm not looking for peak hp, 150-160hp would be ideal

If you can make a manifold I'd get a K03 from a VW or Mini. Still something I want to do, will be crazy peaky for awesome spool but will choke flow to around 160-180 on top. They are crazy cheap, those guys like upgrading to k04s. Or there's the BMW twin turbo M car, get one of those turbos.

There's a few guys done it around the internet, not many here I've seen...

something in the GT2052 size range. it's going to spool fast, make a **** ton of tq at 3-4K, then choke off past 5K. your peak tq will be much higher than peak HP and it would be a very twitchy and unfun miata to drive anywhere but the highway.

Just do a GT2554r

whats the point in turbocharging if only for 150hp

If you want a low-powered turbo Miata, you could always buy a stock MSM.

Having the biggest ***** in the room doesn't mean you'll have the most fun. I would honestly keep my drive train stock if it had just a tab bit more tq.

I have most of the items needed to turbo the NA6, I'm just missing the exhaust manifold (and apparently a different turbo).. it'll be much easier and cheaper to finish this project than to try to sell it and then look for a well maintained MSM

this isn't about *****. this is about spending at least 2 grand to make 30hp

it sounds like you just need a 1.8 vvt swap and nothing else

I suspect that most of us probably said that to ourselves at one time. I know that I did.

Boost is addictive. You start at 5 PSI. Then you upgrade the injectors and add an intercooler. Then you throw a decent MBC at it. Then water injection. Before you know it, you're peaking at 230 WHP and wishing you'd gone just a little larger on the turbo.

You knew it was bound to happen.

I was happy with 10 psi. For a week.

I went up the boost tree like this.

Turbo in and street tuned...

"My car is only 1900lbs, this T25 on wastegate will be fine"

3 days later..

"I wonder if I can get a few more PSI if I preload my wastegate"

2 days later..

"Screw this, I'm getting an EBC"

Running 11psi through this 1.6L controlled by an EBC has been one of the best decisions I have made with the car. The little SR20 turbo spools pretty well considering the cost and availability of manifold/DP combos.

I was happy at 24 psi... for a week. Now I want 30.
