I'm aware the RX-8 has a rotary, I use to own one. HP ratio per liter still applies here since we're talking about the engine itself and not the car.

I thought he meant normally aspirated, as in no FI.

I'm just saying, this is a relatively moot argument. Power to weight ratio is a more accurate measurement for performance.

Im bypassing reading the whole thread, but I had JWT Short ram intakes and made 0 hp gain. Then I put on stillen G3's and picked up about 17hp and it made more power everywhere, not just top end.

Normal ==not $300k.

Comparing HP/liter between the rotary is inevitably misleading as well.

Nobody said it is the best measure for performance, it's just a pretty impressive feat that we will likely never see again in a sub-$100k car.

Yes as "normal" I meant cars that are most of us price range. Now there is debate on hoow much displacement it has weather 1.3 or 2.6 liter...

I would go for the g3 forsure!! I have em on my car already

sr16ve. a 1.6 liter motor with 200 hp. similar to a b16b japan only type r motor. oh and the sr20ve vvel motor. 197 hp from 2.0 liter. both had vvel heads. sr16ve i think redlined at 8500 and the sr20ve redlined at 8000. watch out for se-r sentras with these motors dropped in, they can b very quick.

Did Nissan buy the rights for the variable lift from Honda? I was studying these motors a few years back, and it was a blatant copy of VTEC.

With a decent driver, they will leave a Z around most tight road courses.

Stillen G3 hands down. Don't knock it until you try it!

They're all pink on the inside, but personally the Asians out perform the rest.

....intake analogy ;-)

both of those motors had vvel like our z. vvel is much more technically advanced than vtech. vvel has no intake cam and is computer controlled.
