If you put an EJ25, an FA20, a 4AGE and a 2ZZGE together you can hear the progression from rough to smooth in the engines in that order lol. (subaru boxer with its distinctive rumble, BRZ without the boxer rumble, old high revving inline 4, newer high revving inline 4)
(its harder than i thought finding acceleration videos.....theres a shitton of crap quality ones floating around lol)

(EJ25 i think is the motor)
(FA20 in a BRZ)
(AE86 4AGE)
(2ZZGE, This one's valve lift happens at around 6800rpm)
A few things.

1. That AE86 acceleration video was hilarious.

2. The valve lift in the Toyota sounded very similar to my B16A: [ame="http://www.youtube.com/watch?v=tsehKsRMWpo"]CRX B16A VTEC Crossover - YouTube[/ame]

3. I'm assuming Subaru doesn't do any sort of variable valve timing, do they? I miss my VTEC crossover after watching that Toyota video

4. There is a definite difference in sound between the 4AGE and the FA20, but they sound similar enough to me to make me happy Thanks for the helpful post!
