13b for 93 miata
 

hello im new to the forums.

do you guys know were i could get a rotary kit or something to put a 13b in my 93?

there is no kit, you will have to do all the fab yourself. Alot of work, but would be worth it if you know what your doing.

p.s there are kit for the ford 5.0 V8 and the LS1 v8

yeah i saw the kits for the v8 and man everything together is so expensive... might as well do a 2jz haha jk

Why not, if you have the tools and you know what your doing, it would be badass. Only problem is space with a 2jz. Eaither way, a swap will cost ya. If your worried about money, just turbo it.

wanna know a sweet swap for a 93? a BP.

+ a turbo :bigtu:

The only problem with the BP is that it can only make so much power before it would be cheaper to swap in something else. The problem with that is having that much power in a miata is instant death ;)

Really, How much power is that? Because there are people making in excess of 400 RWHP without tremendously high dollar parts in the BP. Last I checked the cost of a Z06 LS7 motor was about $13k and only made 500 HP.

Really it's the drivetrain that becomes suspect. The 6 speed becomes suspect over 400 RWHP, the axles are suspect north of 300 RWHP, and the tires just can't grab the pavement. The BP motor is capable of making stupid amounts of power with modest amounts of money and major amounts of boost. Unless, of course, you are a pussy who is afraid to turn up the boost.

the only thing a 13b is good for is a boat ancor.

cliff notes: rotary = fail

eh, I love rotarys, the whole ocncept makes sence. Just hasent worked out perfect cuz of those peskey apex seals and the heat. I wouldent mind a rotary miata..

You ruined it by spelling anchor wrong.

Otherwise :bigtu:

Yeah - The rebuild kits for the rotorys are what turned me into a Miata owner. I couldn't fathom $1200 just for the rebuild kit - It wasn't worth it, so I picked up LOLA and sold my RX-7. I don't regret it at all :bigtu:.
I now have better gas mileage and don't have to worry about APEX seals - And LOLA is faster than the RX-7 was. :bigtu:

That's my biggest beef with rotaries; the gas mileage.

mis-spelled words is a trademark of mine :bigtu:

i USED to own a FC, that was the biggest waste of time and money ever. sucks too, RX7s are GREAT cars with a CRAP motors

i would personally do a 2jz swap if i had the money.. 2500 for the motor with auto tranny. but the 6spd cost like 5000. weird... but that would be a monster if a 2jz could be fabbed in there.

Have you guys seen that red miata with the F20c s2000 motor?

Yea I have seen it in the past. Its a pretty sweet setup. He even swapped the digital gauge cluster too. Very nice, but very expensive.

yeah i forgot about, the digital cluster. i was shocked at how almost perfect the motor and cluster fit with the car. but of course i forgot its roadster parts from another somewhat roadster

wow. Seriously. wow.

:bowdown:


edit: great it looks like I'm bowing down to nothing :crx:

You claim the 400 rwhp a lot but there are what, less than a handful out there and none that are true daily drivers.

Making big power for a short time (which most people neglect to take into consideration), and making big power for a daily driver are two different things.

All I hope is that the new rotary enigne mazda is comeing out with will be much beter than the old 13b. The larger displacement is a start. I mean comon.. 9k rpm with like 4 moveing parts, lighweight, and runs so smooth... plus they can spool large turbos with ease. I wouldent mind a rotary car as my non DD. So what if they consume alittle more fuel and alittle oil by design?

What about swapping a turbo miata motor into an RX-7?

Wouldn't you rather have an LSx though?

Not after Phillip's experience.

There is a kit. I don't remember the name of the company that makes it though, I think they're based out of Florida.

And the kit is like $4500 for some engine mounts and other stuff.

It's been done before (rotary in a miata) and if you want to do it all you have to do is write the check(s).

Swear to god.. Theres always someone.

Forget the rotary unless you really like failure.

Mazda BP 1.8 from Junkyard is like 100$ for the longblock.. at least, thats what I've bought like five of them for now...

The problems with rotary is the fact that they're turbo'ed. N/A lasts far longer... but at the consequence of power. Though a good port (1/2 bridge as a full bridge port is hard and cn shorten life) can make a big gain. Hell, a carb'd 13B with a large street port and big carb would be fun as shit to drive. Or just say fuck it and p-port it buahahaha.

Now, if you really wanted to make a lot of power and TQ without a V8....and money was no object, there is always a n/a 20B. I have seen a 20B n/a with a custom header (duh) and tuned with a MoTec make 380hp. Now, if you were to take the high-comp rotors from a S5 and do a street port, you'd be looking at well over 400hp and dependable at that...

oh when i win the lottery......

My friend told me that the realy problem with the FD wasn't the apex seal but overheating which led to the seal's failure. He said he read an article about how someone modified the radiator placement and basically double the life of the engine (from 60K to 120K...)


-t.t.

P.S.

here's a sportscompact article.

yeah i was thinking about the 20B and p-port it cause it sounds monsterous lol but it also cost way more then a 13b... could find a good 13b for 1800 but 20b for about 4000+

you DO NOT WANT to p-port any kinda of "reliable" car lol. Almost no idle, wears seals very fast. But a p-port 20B could make unfathomable amounts of power lol

Sadly, there is a shop in Ga where the owner "collects" 20Bs... there are like 20+ of them just collecting dust. :(

Sounds like me and you need to take a visit to this guys shop

oh no im not looking for reliable lol i have a hybrid to daily drive. but yeah i would pick up 2 of those 20b's have one for the miata and build a damn gokart with one lol

I guess that really is how you could turn a miata into a money pit. Install a turd under the hood. Jesus you'd be better off with a D15 honda engine..

haha d15 sohc lol

While we are on the topics of ridiculous engine swaps, anyone ever consider a diesel?

haha never thought of it. redline at 2800 rpms but can tow a boat with a miata

Don't tell that to the guy who took an endurance championship racing one! NASA series a few years back. 270 RWHP N/A 13b. It was fun to drive but loud as hell.

Yes, it ran 11,000 RPM.

My sisters beetle has a red line of 5500 and isnt to bad with the DSG.

Its like 90hp - like a stock miata, but has like 180ft/lbs of torque.

we we are probably much lighter! but i dont know.. never knew how much those weighed

4g63... that was MY idea :( i've always thought about it since u can convert the AWD to RWD

id go with a supercharged s2k engine with about 300 hp.. thated be sweet.

404: Torque not found.

LSx.

id go with a 1.1 Yugo motor
actually two of them, on up front one in the back
yeah, AWD Miata
NOT

DJ you are in Houston right?

PM me if you want to talk. Why did you sell your turbo kit for a swap. Should have just gotten an ecu and called it a day

I've considered a diesel swap... I'm waiting for the BMW 120D engines to age a few years so I can pick one up cheap and import it. They rev to about 6K and make good power and torque. They also get about 3X my current city fuel economy. I bet with a slightly larger turbo and some stage 2 injectors I could make that engine perform very well. I won't be doing that to this car though, I'll get one that's a little more beat up and use it as a DD.

how about a SR20DET? i remember seeing a miata have that and it seemed to fit the car well

Yup, and there's a guy up the road from me with a p-port in his 70-whatever rx7. Last time I was over, he fired it up for me and we rode around the block. It was so loud, one of his neighbors called the cops. He was shifting at 10k. :bigtu:

why. Turbo 1.8 can make the same power

Torque++

Those pigs are heavy, 3000+

i guess he wanted to be different? lol i wouldn't do it. id just turbo my stock 1.6 or get a 1.8 to a 2.0! and boost

If you want to be different, slap a 2.3 MZR turbo in. Stock form you've got 270hp/280tq and be done with it.

you refer to yourself as "he" now? As well as act like you didn't start a thread about engine swaps......

Ok, really, id have 2 miatas. one with the supercharged s2k engine, and one with a supercharged LSX... as long as monies dont count :eek5:

Well then, since you're buying... :cool: I'll take two, please.

if you read the post before the quote, i was talking about how i saw a guy do it. so thats why i was say to pitlab i guess he wanted to be different

You know what would be intresting? A turbo 5cylinder audi engine. Would sound badass.

DIESEL! Then get a banks kit, bullydog exhaust, stacked chips.. And some propane! :)

1.8 2.0 not much of a difference.
