hey everyone,
I own a 92' miata and tryin to throw a 13b turbo motor in it. I was wondering if anyone could give me a few pointers or advice on the pre cautions i might need to know before I put the new engine in. So if any of you guys could help I'll appreciate it.
thanks,
cmroczka

I don't know of anyone on this board that has done such a thing. In fact, most people on here will argue endlessly that:

A. W(hy)TF would you want to put that engine in.

B. Search more.

C. Although not horrible, watch your grammar, and add a helpful thread title so we don't have to look at your post just to find out we can't help you.

That being said, welcome.

Having played with turbo rotary motors a fair bit, I can say with some authority FOR THE LOVE OF CHRIST RUN AWAY. It sounds like a good idea, but when you eject an apex seal onto the car behind you / overheat and warp a coolant seal and then look at the cost of a rebuild, you will cry. However if you feel like you know what you are getting into, and are determined to be different, good luck. Dont skimp on proper engine management, buy the biggest injectors you can afford that you can still idle ( and have fun playing with sequential injection ). And start saving for when you inevitably break it.

Yeah, I know the concept of a rotary engine sounds cool. No pistons, no connecting rods, yada yada yada. I've heard of people with Rotary engines making big power, but dude, seriously. You want to leave that 1.6 in your car, and just call BEGI or FM and order a kit without the management and at least a GT2560. Then get a MSPNP, an LC-1, 550cc injectors, and a decent clutch, and be more than happy. The money you will spend doin it this way won't even be half of the money you will throw away on parts that you will break on that 13B.
Oh yeah, WELCOME TO MIATA TURBO . NET

You will probably need to modify the oil pan and possibly the tranny tunnel\ power plant frame.
I suggest you read this Rotary Miata FAQ!

As the former owner/racer of an rx7 all I can say is "Hahahaha!"

Seriously, you could actually end up making a small fortune doing that swap, if you started with a large fortune.

What makes less torque below 4000rpm than a 1.6 Miata engine? A rotary engine.

Don't get me wrong. There were things I liked about the rotary engine. I liked the way it revved. And uh...the way it revved, I guess. OK, there wasn't anything else. It was tempermental, fouling plugs, and not cranking cold. They flood easily. They have a very short lifespan. They are expensive to have rebuilt by anyone who will actually stand by their work. Many people who rebuild them use parts that should be junked and replaced, so you never know what you are getting. Did I mention that a naturally aspirated Toyota MR2 can take you off the line? Did I mention that they are troublesome and expensive? Did I mention they lack torque? Did I mention that they have a very short lifespan?

For the same money, a turbo Miata engine could be built that would be reliable and make similar power but for years and years longer.

But you will do what you want because we don't know anything. We must all just be haterz.

unless you can fabricate anything you do for the rotary into miata build the 2k is gonna be what it takes or more to get the rotary into the miata.

Begi for turbo kits, you can get their shangai starter systems for less than 2k and shanghai turbo kits as well

How were you going to fund your rotary swap if a couple grand on a turbo kit is too expensive?

Put the crack pipe down and troll elsewhere.

appreciate the info,

Just an engine in respectable condition would cost abuot the same, not to mention all the extra fabrication in order to fit in. Take the advice, and just turbo what you have.

As someone who long ago thought a rotary in a Miata sounded like a ******* great idea, but now has a turbo'd 1.6L....please take the above advice.

There are much better options out there, especially if this isn't your 5th engine swap project.
