MZR DISI Turbo Swap: Can It Be Done?

I looked at the rulebook for the IDRA. It read, and I quote "Engine manufacturer must match vehicle chassis manufacturer. Brother subsitutions are allowed such as Lexus/Toyota, Nissan/Infiniti, Honda/Acura. Domestic manufactured engines are limited to four cylinder and OHC six cylinders." No Chevys in Mazdas allowed here. I am pretty sure the same go for other sanctioning bodies (in drag racing).This was true for all classes except for the bracket and outlaw classes. Personally I am not a fan of Bracket racing. It is not as fun to watch and does not get the attention as heads up racing. The outlaw class is basicly a pro mod like class that will require an investment of 100's of thousands of dollars (car, support, etc).
If you never plan to compete, than I would most certainly agree that the other swaps are the way to go.
My goal is to compete in a heads up class. To have any hope of winning, you have to have a motor approaching the maximum cubic inches. An older Miata would be more competive with a developed NC motor, because there is the potential of getting more cubes out of it.
That is why I think someone should try the swap. It will take a lot of development time and money. But it would be great to see the Miata kick some Honda ***.

And yes, many different tracks will have different rules, as classes. A friend of mine races in mini stock, and the rules for that are it has to be a SOHC engine, carburated, must be the same manufacturer motor, and for every litre of displacement you have to have X amount of weight in your car... They normally try to make an even playing field, so they punish larger displacement by adding more weight. So really, a 1.6L can compete with a 2.4... it's how it works.
And I agree, just GTFO.
PS - competing with Honda's with a mazda engine (except for rotary) is futile. Honda has a great design, and the support is insane. There are many 1000HP honda civics out there. I don't care what you say, Mazda does not make a block in conventional form that can be built to that. Your only hope if staying with mazda is some 3 or 4 rotor setup.

What seems to be your problem?

OMG why are you so retarded? Have you even tried bracket racing? At least it requires skill and some amount of brain cells. It's not merely "may the fastest car win" fest. And seriously, have you ever actually drag raced a car? You'll find bracket racing is exciting, and at least gives everyone a hope of winning. And bracket racing has huge favor with professionals as well.

Before you act like you know something about me, you may want to ask a few questions.
You know, I came on this forum to learn a trick or two. And you know, I might teach you a trick or two as well. I was giving arguement as to why it would be a good idea. Maybe it is not a good idea, but act like something other than an 8 year old will you?

Lad, I have been drag racing for 15 years. I have gone faster than you ever will, and my normally aspirated miata will blow the doors off your piece of ****.

How many months did you spend "doing something the same"? 
Doing an engine swap because you want to is the only reason you need IMO. Some actually like the problem solving and fabrication that goes along with a project like an engine swap vs. mail ordering a kit and installing it over a couple of weekends.

I've also seen us run off a couple of experienced older guys that were just lacking forum etiquette in the past few seasons.
I was responsible for one of them...and feel like an asshat for it.

Well most internet forums are not known for their tolerance. You just have to shrug off the intial wave of e thugging and go about your business.
I understand the need for a larger displacement motor but the other factor in your MZR choice is the engine management. with direct injection you may be limited to factory ecu with something like the Accessport from Cobb. There may be some standalones that can control DI motors but I am not aware of them.
For drag racing a 3 rotor 20B would be really cool but might not be legal as it was not sold in US.
Personally I dream of a Hartley V8 with twin turbos but since I could just buy a porsche GT3 for the same price I'll let you know.

Like kaisersone and myself have said MZR will be a nightmare to get running, theres one guy in Ukraine who is currently working on cracking the mazdaspeed6 ECU (AWD) Id guess you would use mazdaspeed3 or FWD CX-7 ECU in a miata for it being 2 wheel drive not 4.
Either way, I would love to see it done, but over 2+ years of personal involvement in MZR engines I would advise you to stay away from it.

lol...we really don't need a banstick yet, we'll run him off soon.
Want to go drag racing? Buy another car. You're sounding like a 15yr old keyboard cowboy with ideas and no money...or logic There is another Miata engine that has the same output as the NC's 2.0L and drops right into the NA....but obviously you're so stuck on the MZ i'm not going to bother telling you. There is another 2.0L 4 cylinder that isn't too hard of a swap into a Miata....hell, there has even been one guy who had a V6.
I don't really see anyone doing too much with the MZ because of Mazda's retarded ECU. No one is going to care to really crack it because there are much better swaps out there for the money.
