Fastest N/A KA24de

NO, NO, NOall wrong,.....13b, means 1.3 liter. each rotary has a displacement of 655cc. Now times that by 2 and you get 13ish. Silly.......All of displacement is the same, doesn't matter how many cylinders you use. So, YES, 1.3 liter is keeping up with 3.0 liter supra. Do some research, before you try to tell teach someone. not trying to sound like a jerk, but how can someone learn the truth, if he's being told lies. Also, you can't really compare a rotary engine with a piston engine cuz they both work completely different.COMPLETLYlol

You're the one who needs to do some research. A 2 stroke engine maybe rated at certain displacement, but it's still pumping twice as much air as a 4 stroke per unit time.

All I'm going to say, is a twin turbo 1.3L engine puts out 255hp from the factory, in a 2700lb car. I'd like to see a stock LS1 up against a stock RX-7

[Chezedik]

Easily accomplished. The torque is much more usable in the LS1, but over the long haul, the 13B would do well if it were modified. Twin turbo probably means Twin (small) turbo. Although boost would be quick at stock settings, the gains would probably be minimal from increasing boost without a larger turbo. My .02.

There is a local RX-7 owner here in KC with an LS1 powerplant.

Maintained near 50/50 weight distribution and tipped the scales with less than 100 lbs increase with the LS1.

So I'd say the 320 hp engine is going to be considerably faster than the stock RX-7 with only 100 lbs less weight.

Who did that? I would think I would know them. But anyway, what a waste, why would you go through the hassle when you had such a nice thing as it was. Gas mileage I guess...

and huge power potential

unique

maintains excellent balance

reliable

etc.

But, the reason you buy a FD is for the rotary engine! At least, in my opinion. The same holds true for any car. If your car somes with a KA, beef it up, turbo it, supercharge it, do whatever. It's your powerplant! Obviously a LS1 FD would beat a stock FD. There's some guy here in NC that did a LS1 in a Zenki, was up on ebay a while back, stock, but 11.9 sec 1/4 if i recall correctly.

Not quite stock withn LS1, but I get your meaning. The FD is a light vehicle, and from what I understand the FD's rotary is rather temperamental. I could see replacing it with a V8.

As for Chingon saying that a 2stroke makes double power, not quite. The valves are on the side of the cylinder, as the piston unshrouds the valves you lose the rest of the power stroke. Plus I understand that 2 strokes are horribly peaky.

I disagree entirely....only because one count of detonation on a rotory can lead to blowing an apex seal.

All I care about is function. I'd buy an FD for it's amazing looks and handling characteristics...and if I can retain both of those by swapping out a torquey, reliable, comparable weighted LS1 I've no reason not to.

Other than I'm sure the swap sucks.

[grimlunacy]

Wow has everyone ever gotten off topic. to make it simple. power to weight ratio is what it is all about. if the car with less displacement has less hp then a much larger car with much more displacement id put my money on the smaller car. weight is always the issue when it comes to speed, hp is only a small portion of the equation. weight, suspension, rear end type, body design. think about it. Plus comparing a 5.7 to a 2.4 is like comparing apples to oranges.

One count of detetonation could lead to blowing up any engine... I never said rotaries were reliable, they're not. In fact, as the years progressed, RX-7s became less reliable. I've seen FC's TII's with 130k on the original engines, I think the most I've seen on a FD is 100k, maybe. They are famous for their engines, not their looks. It is the combination of looks and the fact that 1.3L easily puts out 325rwhp on stock turbos. (Friend with a Power FC just dynoed last week at 326). Sure, reliability it definitely important, but I think preserving the original powerplant is imperative. This is just my opinion of course, and I'm sure plenty of other people disagree. Oh well.

My STi would see detonation all the time when I experimented with tuning and it never had any problems....as most engines can take a bit of light detonation...depends on the severity.

The problem is...detonation I was picking up from the computer wasn't audible....and that's typically not going to be a problem on most engines...but on a rotary even in-audible knock can be fatal.

My buddy has a 400 whp fc and went through 3 engines until he realized he just couldn't fudge with the tuning. He had to run the SOB rich as hell to keep the engine alive.... whereas the LS1 FD is going to put down close to 300 stock.....getting 100 extra hp is no problem at all and the engine will still be very reliable and have a lot more potential.

meh...maybe to each his own. Personally I wouldn't want to deal with a rotary...just too termperamental of an engine....not to mention worst gas mileage to liter ratio...ever.

[97ka-t]

hahah I never even thought about the gas mileage to liter ratio. That has to be true, my friend with the 325RWHP FD gets an average of around 11 to the gallon... Whatever Lamborghini Diablo V12's are, they supposedly get 11 too.. hahah

1.3 liters and 11 miles to the gallon. DAMN
