It only takes 20 years to be considered a classic.
The FA20 was built with a mind towards clean emissions. Toyota has their "environmentalist" credentials to consider. Hence the Toyota D4S system under the squidcap instead of the Subaru Direct injection system. If they had wanted to build a higher output engine or a turbocharged engine they very well could have. The peak HP isn't as important as the torque curve anyway. And the FA20 has good torque for an engine of this displacement. Better than any Honda. |

If you want to win rolling races in the freeway, an engine with peak torque at higher RPM (6500 rpm) should win you more than an engine with peak torque at lower rpm (2000 rpm) -- this assuming that both engine are rated the same power and have around 12lbs/hp power to weight ratio. The engine that has a peak torque at higher rpm also gives you higher trap speed and top speed and longer power band (at high rpm). However, an engine that has a peak torque at low rpm is better at towing, hauling or rock climbing application. Probably will get a better 0-60ft head start but are usually slow in accelerating at high speed. Remember that HP is a function of Torque.. so where ever the torque peaks, the HP curve is always affected.. HP and TQ will always meet at 5252 rpm.. (using lbs, ft, hp .. as units of course). |

The 2-stroke and the rotary both have the advantage of aspirating their full displacement every crank rev. It would make more sense to refer to a 2.0 4-stroke piston engine as a 1.0 liter than to call a 1.3 rotary a 2.6, or a 250 2-stroke a 500. In both the 2-stroke and the rotary cases, thermal and other issues don't quite give them the 2x advantage, though. It's more like 1.5x, a bit less, really. A 1.5x equivalency factor (1.5x1.3 => 2.0) for competition purposes would make more sense than a 2x factor (2.6), to be as fair as possible. But it's still physically a 1.3.

So where is the REAL Brz STi?
you know the version where they lower the weight through using more carbon fiber and tuning the engine to get an extra 20-40 hp? I don't care about turbo and i'm fine with NA... just give me a legitimate STi instead of one that is just full of cosmetic "upgrades" |

You're talking about a "fantasy" BRZ STI until further notice. |

Lol, gimme a break man. The stock brakes are more than enough for track duty. All you need are track pads. And guess what, even with these fancy Brembo's you'll still need track pads...that won't come standard from the factory.

^ THIS.
people think because you have more piston/surface area etc etc fancy 4 pots you can now brake harder. well guess what, you can cook the OEM brakes just as fast as you can cook stock brembo'sc i've seen it happen to cocky people all the time, people think brembo's make you invincible. there is no replacement for good pads, SS lines, and fluids. |
