hey what up guys? i was just wondering something, the 13b has a displacment equal to a 2.6l piston engine even though it is only 1.3l right? so does that mean a 13b will have the low end and response of a 2.6l pushing equal hp and running a simiular spec turbo?.(i know tuning comes into play but i mean generally)



a 13b definitaly doesnt respond like a 1.3l i know that cause honda 1.6s suck. a 13b definatley has better response than a 2l right?



im just trying to get a feel for how a 13b stacks up compared to a piston engine.



thanks

no one can answer that???

I think some of us can answer, but you have to give us more than 2 hours to post it...



Comparing a rotary to a 2.6 might be doable, but how many 2.6 motors are out there? Seems like 2.6 Litres is good for 6 cyllanders, but it could be a 2.6 inline 4 could it not? What does Nissan have?



Rotary's are still a different way to make power, even if you stacked a 13b-T against a 2.6lpiston-T I think the torque and overall HP may be different. Different curves on the dyno.



Hope that helps bro

how bout taking the rotary engine for what it is? its like comparing apples and oranges.

Exactly. This isn't a piston engine, its not 2.6ltr or whatever people want to believe its equivalant to. Its a rotary engine, it has 2 rotors and 1.3 litres, end of story. Completely different than a 4 banger, 6 or 8 cylinder. A 3 rotor or 20b has 2 litres.

the way you're saying things....



a 4.0L 4cyl, 4.0L 6, and 4.0L 8cyl would all have the same properties as far as proformance... but they will all have different characteristics. hell, a 4L v12 from an F1 car is no the same as any of those

tecnically yea, a 4l 6 cyl can perform exactly the same as a 4l v8. it has nothing to do with number of cylinders when it come to piston engines its all about displacement.



but i find it hard to believe the rotary 13b behaves like a 1.3l cause quite honest that would suck, i heard the n/a ren. in the rx8 actually does have shitty low end and no tourqe but i still cant imagine it behaving like a 1.3l. whitch as you said its a rotary so it doesnt behave like a 1.3l piston engine.



i was simply trying to get an idea of liter piston engine would feel most equivilent to a 13b. my best way to understand would be compared to a sr20det. would you say a 450 13b would have better lowend and response than a 450hp sr20??? i mean hp is hp and tourqe is tourqe and thats what im trying to see what it equals to , im not trying to directly place a piston engine displacment on it you know?

Actually... "tecnically" [sic] alot of things can depend on the number of cylinders, how many valves, OHC vs pushrod, stroke, bore, forced induction etc.

"FikesRxSeven" is right, it IS like comparing apples to oranges, and your assumption that displacement is the primary determinant of an engine's power characterists is all wrong.

Personally my FD makes power like no other car I've owned, which is part of the attraction of the car.

You're obviously very concerned with this low end power thing. Go buy a V8.
