Here is just some of the stuff we here in Kalamazoo MI do with our spare parts/time.
SHO motor dropped into a 4ws mazda 626. 220hp 5spd.




Another creation an early 80's Rx-7 with a 200hp 929 v6 motor=highway wheelspin.



yup that's nitrous. Enjoy!

Karma is appreciated:tup:

Who woulda thunk to put an old 929 motor in anything? Pretty cool if its fast though

uh the sho is pretty fast and the rx-7 is even faster. I personally have no affection for the sho motor, but encourage creation because it is different. These are not my cars, that being said the SHO 626 is ridiculously faster than my stock 626 turbo.

Waste money? The only investment on either of these projects was time Darren. I personally have no affection for the sho motor, but encourage creation because it is different. These are not my cars, that being said the SHO 626 is ridiculously faster than my stock 626 turbo.

points for being different! that is for sure! I know I love it when I am at shows and I see a motor that should just not be under the hood! and I love to see the 3g rx7 with the ls1 in there! :) someone from my hometown has a monster miata. he has the v8 swap kit and he boosted it! that thing is nuts! not to mention he cut off the top and the hood to cut weight. I have watched him run my buddys supra that had 998 at the wheels and it was interesting to see! but the sad thing is a stock neon would kill the 2 of them from a lauch cuz all they do is smoke there tires! ahahahhaha!

no love for the sho engine? i think its a great choice to put in the car. anytime you replace a sohc junk engine with a more advanced one is a great move.

you see them in the junk yard all the time. nobody wants them:shrug:
If i was going to swap and engine, id put something worth while in it..
Something that has potential and reliable.

You see MX6's in the junkyard all the time too.:rolleyes: Not to mention Mustangs, Camaros, Escorts (Which are one of the most reliable domestics ever)

Dont make ignorant statements. Your dislike for a motor means nothing for if it's actually a good motor or not. It's a better, faster, and just as reliable motor as the KL. People just dont know how to take care of the motors. The SHO has just as much potential as the KL.


With that motor in a 2g MX6, it would run circles around a KL-powered one. Hands-down. Sounds worthwile to me. Doesnt even require a turbo kit.

major points for effort and originality.. ever since i started hearing about the FE swapped miata ive been dying to get my hands on a 91 or so miata to slap an f2t into it.. as a matter of fact i still have my f2 motor that has less than 30k miles on it. however all the miatas i find are too nice and still going for up past 3 grand. im confident a f2t in a miata would just be incredible. i havent heard or seen any swaps out of the ordinary or that compare to the 2 you shown

rebuilding a SHO V8 engine would be worth while. its a V8 engine that actually won't hurt handling when front mounted since its smaller. and it makes 240hp/225tq stock. i bet with a rebuild, intake manifold port and polish, headers, etc you could get 300 N/A and still have good handling. a high reving, high compression SHO engine would be a beast on a road course.

as for the rx7, i don't understand why you would replace the rotary engine when its lighter and can make much more power with a turbo, reliably.

You're joking, right? I'm not sure about that V6 they put in there, but Im sure its right around the same weight, and 2x as reliable.


If they were so reliable and that much lighter than standard motors, then people wouldnt be replacing them with LS1's in the RX7's. IIRc the LS1 is only about 50lbs heavier than the rotaries. If they were more reliable, then there wouldnt be massive recalls on the new rotaries in the Rx8 either

If you can find a transmission to go along with that :lol:

You've never seen a big ls1 swapped into a miata? I saw one a few years back... insane...

Forgetting a couple details. An all aluminum long block LS1 is only a little heaveier than a TII setup including all of the plumbing, manifold and turbos. And you cant compare the 13Bs to the new Renesis, they're different.

I wasnt trying to compare motor-motor. They are quite different. I was just trying to show the reliability of a rotary motor by showing that both are far from reliable.:shrug:

Thats only because half the people that own that have no idea what they should do for premature failure. Most people wake up when its 10* outside, start their car and go. Rotariess need to be warmed up before seeing anything higher than idle. If people allowed them time to warm up and cool down, I'm sure there'd be considerably less issues, but most people have more money than brains when it comes to cars.

The rx7 is the fastest Mazda i have ever been in. In the rain @70mph on the highway it will spin the hell out of the tires in fifth when you mat the gas. It wasn't soaking out but the pavement was wet. Thanks for all the responses, the V8 SHO as i understand is crap unless the cams are welded down. Ford knew there was a problem with the v8 when they sold them. Ford ceo meeting, "uh, what are we going to do with all these bad engines? SELL THEM!" Got to love FORD. The v6 SHO is a dime a dozen comparatively, who really thinks of a taraus having any performance really, surprising. King6 just keeps up his commitment to cut-downs. The SHO is a good motor, or aleast as good as the KL, but with lots of power to spare.

reliable as you make it

Not really.

Rotaries are no more or less reliable than any other engine out there. The difference lies with the user. Seriously. N/A rotaries are reliable as rain. Turbocharged ones? less so..but the same could be said for any turbocharged engine.

Swaps to LS1s? This is more of a "people" thing than an indictment on a particular engine. "people" have convinced themselves of a particular truth as they see it..."rotaries are unreliable" or, "LS1 is reliable", or "SR20DET>*". Really though its a matter preference. In this age when anything can be swapped into anything else, why not have everything you want? Handling, torque, reliability(as defined by the individual). Again..more of a people thing.

Ill grant you, its a lot harder to muck up a pushrod V8 vs a turbo rotary(or any high tech multi cam V8 as well). A turbo rotary is a different beast and requires more attention to detail...and maybe thats the problem right there? Torque just isnt there in a rotary as well. Some folks manage to live with this though.

Its all down to people, and people are strange.

PS: I have no "dog" in this fight. I see the proponents of (insert bestest motor here") over something else all the time. Im sure that all of these motors have their place and benefits.
