I�m just talking in general,
if you have a HP spread from 200-500hp, does it matter at what rpms?
or what torque is at those rpms?

No it does not ,

a 13b can make close too 200hp on stock ports with just about everything done (ported throttle body, ported intake manifold, injectors, modified 6 port system, headers full exhaust etc, a mildly streetported motor can hit 210-240 (depending on how mild and other mods) again though that really wouldnt come into its own in a e30 there just a little 2 heavy for the rotarys lack of torque in my opinion, now put that into a first gen rx7 or a porsche 914 and you have a pretty good street car/track terror. Turbo rotarys are another beast altogether and you can get too 300 hp fairly reliably (relative word in turbo rotarys) you get arond 400 in a 2nd gen turbo motor (13bt) and its generally a ticking time bomb, Though 3rd gen rx7 motors are awesome, (13brew) and are capable of 400 reliably and more if your careful with tuning but they are pricey.

ohh yeah and the 20b is a 3 rotor (an amazing motor by the way but ridiculously expensive too work on), mazdas lemans car had a 4 rotor called a 26b i believe? which made 400 hp na on 83 octane if i remember correctly, its been awhile since ive been around rotarys, i owned a 87na rx7 back in high school.

To some people it does. For the street, I don't want to be revving to 8k everytime just to get it going. I would rather have a good broadband hp/torque band on the streets even if it means sacrificing some ponies. I also don't want a peaky motor where I'll only achieve peak hp within a 400rpm range.

Broadband power is why a lot of people buy European cars when it comes to the power department. Something a lot of the smaller Japanese cars don't exhibit on na motors.

I agree, but In strict math terms HP is the final ruling when it comes to accelaration,

I like a peaky motor, i.e builds up to a final scream, I hate revving hard and feel the torque build up take a nose dive and the car falls flat on it�s face

Also, with the right trans and diff gearing you would never be the wiser to what rpms you are at unless from the noise or tacho,
Well you get what I�m saying

If you want a Japaness car buy one , you cant do that to your BMW for the love of BMW don't do this

I'm totally looking for another motor to put in a E30. I like the chassis, but the motor sucks. The other german motor options are pretty heavy for their power and cost, so I'm also looking at something non german to pop in there.

The fact that BMW people don't like it makes this idea that much sweeter. "Mmmm Bimmer boy tears..."
