Don't believe me, look up any NA 13Bs factory numbers, and look at any other 1.3, then look at say a 2.6 Caviler. I rest my case.
i know this. if you notice sometimes the displacement has a x2 after it. mostly this is shown on some video games and some spec sheets. but its advertised as a 1.1 for the 12a.

true, that's why rotaries drink so much gas like any other 2 stroke engines cuz the power stroke comes on more often.

but very true

and I don't care if they can't go 200,000miles w/out maintenance, ROTARIES ARE THE SHIIT

rotaries are the ****, if i didnt love 240s so much i would definatly be driving a 2nd gen. and for not being reliable? there has been rotaries with over 350,000 miles on them with just standard maintenance and of course not beating the living piss out of it.

^ exactly. i dailyed my fc the 45 minute trip (one way) to school and back every day for 2.5 years. it didn't do good on gas, but the only reliability problem i had was a leaky injector, but thats nothing. even when it would flood, the series 5 is smart enough to unflood itself

No, I can't say that I've ever noticed that. If Mazda was responsible for putting the x2 in print, I would hate them a little less (I don't hate the Wankel, I hate Mazda for their abuse).

That makes no sense. 2 strokes get great mileage, and the powerband is up high. It gets there quicker due to a reed valve or simplified pressure operated pop-it valve, rather than a cam driven mechanical valve. That's about the only similarity between a 2 stroke and Wankel.It consumes fuel around the same rate as any other 2.6L.

As far as reliability, I have only seen a hand full of 13bs make it past 150k, but that is absolutely no fault of the engine. It's the dumb *** owners abusing them. They are known for their weak apex seals. However, if driven like you actually care about the car, you should never have a problem with the stock ones unless introducing forced induction, or higher levels of boost.

There's a reason a large number of light aircraft use the Wankel.

2 stroke dirt bikes use a lot of gas compared to the 4 stroke ones, but 2 strokes are more efficient making way more power out of small displacement. So yes, you can say that a 2 stroke gets good mileage for their power but they still drink a decent amount of gas for their displacement. Theoretically, a 2 stroke engine will use twice the amount of gas for every intake stroke on a 4 stroke engine.

The wankel motor gets better mileage, but as far as the mazda rotories they aren't getting very impressive MPG ratings.

lolololol,

so every on likes the "400whp @13psi" blown engine....FYI An LS1 + T76 Made 560whp @ 8PSI And 783Whp @14PSI...

All on 95 oct Fuel....

Also A 427ci (7.0L) LSx Made 2800 Whp @35 PSI (Drag custome made engine)....With TWIN GT47-88s

Who's laughin now bitcxh?

It's true, rotary powered cars seem to be very reliable, as opposed to what some say. Everytime I go to the track, it's the SR / RB / KA powered 240s that end up breaking down, and the FCs always drive home. Sure, sometimes the FCs will break something stupid like an axle, but it's never a major engine problem, whereas I've noticed lately that a lot of 240s at the track have been having major problems like rod knock, overheating, or burning ECUs.

of course, it was rotary power that won 24 hours of le mans in 91, they can take a beating

Then immediately below...he even didn't run the "cooling Lab" why....b/c he didn't want it to blow on the track....@ mazda's booth....BOOOOOM rotary

grammar owns me

So true! N/A rotaries are unbelievably reliable for racing. Gotta build em' right, but that's the same story with any race-ready motor.

i loved my NA, the only reason i'm not driving it anymore is i pulled the na motor and sold it for $800. it'll get a 13bt eventually but i'm working on the s13 now

I'll keep my SR. Tanks though.

It's a cool project I suppose.

Oh c'mon! Thats like comparing apples to... really big f**king apples! Of course that would be expected from an ls1 with it's higher displacement. But you can't deny that those kind of numbers from a small displacement motor is quite impressive (if you can keep it running, that is..).

BTW, I'm not really a fan of this swap. I'm just commenting...
