The only issue I have that I would call out as simply incorrect is referring to the COG. As @ Jaden points out a couple posts above this, the COG benefit from the boxer motor is not one of front vs. rear weight bias. Rather, it's a measure of weight from bottom to top of the car. The FRS/BRZ's center of gravity is 18.1 inches. That's lower than the Porsche Cayman and lower than a Ferrari 458 Italia for example. This was the focus in engineering this chassis and this is what the FA20 motor was designed for.
Any other engine swap will increase the center of gravity height and that will have an adverse effect on handling.
I'm not saying the extra power doesn't make up for it in lap time or that other motors are easier to maintain or can handle more power, etc.. Those are all very valid points. But at this point in time, I think adding power to the FA20 is the best bang for your buck and you keep that COG as low as possible. We all know Moar Lower is Better! |
Yeah the main short comings in the frs are a lack of power and loose tires stock...
Throw some TRD springs on it, or coil overs (maybe) if you're going to track A LOT and a supercharger to get to ~300whp and the frs hits supercar territory as far as performance.
Unless you're wanting to turn it into a drag machine, I think around 300 whp is the magic number for the toyobaru twins and people are getting that with CARB approved stuffeses on pump gas running less than 10 psi boost.....
so let's go have some fun in our toyobaru twins... whether it be autocross or
cruising down the highway... or mountain terrain or burning up the quarter at 11 seconds...
