2.5L with lower revs/more torque, or 2.0L with higher revs?

Assuming that Subaru/Toyota was listening to you, which would you choose? I think that these are both likely options as a high revving 2.5 is likely not in the works.

Choose wisely.

2.5 with less than 7400rpm? Is that what you're trying to imply?

Gimme revs and displacement. No reason they can't make a 7400rpm 2.5 liter.

I went from a 7000rpm 2.4 liter I-6 in the Z to a 7000rpm 3.1 liter. BLISS!

The 6.0 liter in my FD spins to 7000 as well. Yee-haw!

Don't wanna hear about any 6500rpm 2.5

A proper header and tune seam to fix the torque problem, lowering the redline would really hurt the sporty feel of the car IMO.

I would be happy if the 2015 model came with a torque dip fix, and 8k redline and 230/240hp.

Ill take higher revs and 2.0L. I want more specific output from a screamer. Its all in the intake manifold design.

Answer depends on weight difference of two options.

Then 2.5L for sure.

I spend 99% of the time in the rev range that would be positively influenced by an extra 500cc. If I had to give up 1000rpm for that, which I only use 1% of the time, I would.

Of course, I would rather have the best of both worlds; as others have indicated. But, sticking to the OP, I would go 2.5L and less revs.

Everyone is going bonkers now that the 2015 rumor started...

However, if I'd have to choose, I'm with @ZDan, 7400+ and 2.5!
