Finally got around to go test drive an FR-S. My verdict:
The engine. Oh the engine. I can't come up with a single positive thing to say about it. It sounds terrible. It has acceptable response, but not what I'd call good, which is a mark against it, being normally aspirated and all. The engine is also very rough. Im not sure if that is typical for a flat four, but it feels tragically unrefined. Where is the power? Honestly? I'm used to a rotary where you have to fish for the power in the upper mid range and top end. The H4 in the BRZFRS, though, doesn't seem to have a bottom, mid, or top end. There is a slight burp of torque just before redline, but then you bounce off the limiter. It honestly did not feel significantly quicker than my 100hp Mazda2 (the Mazda has a very large weight advantage) and my RX-7 (carb, exhaust, intake) would walk all over it from any point in the rev-range, and deliver much sharper response, smoother delivery, far better noise, and a broader rev range.
I've had my '86/FR-S for about 4 months and I only just noticed this thread today.
For the record, I can tell you that my engine and gearbox felt considerably smoother and more refined, post break-in period. I expected the gearbox to feel a bit less notchy once it had some use, but I was amazed how much smoother the engine felt after about 1500 miles.
To me, the engine output and power delivery from the 2.0 flat four, is broken into 3 distinct zones.
1) 2,000~3,500 RPM Keeping in mind that it's a NA 2.0 liter powerplant, I think the engine has a very flat and strong torque curve. In fact, I don't think I've driven a car with a normally aspirated engine with 2.0 liters or less of displacement, that felt so strong at this rev range. Of course the car's relatively light weight helps.
2) 3,500~4,500 RPM This is the 'dead' zone. The torque drops off very noticeably, just at the point where you expect it to be coming into stride. It's a bit annoying.
3) 5,500~7,500 RPM At this point the car really 'comes on cam' and is fully alive. It feels strong and pulls strongly, similar to many high-revving, small displacement in-line 4 cylinder engine.
I have a TRD exhaust and TRD airbox, so that probably helps it breath, and it certainly sounds better than stock, but I doubt combined together they're good for more than 10 at-the-wheel, horse power. From what I've been told by other owners, an after market header and a good Ecutek tune goes a long way to improving the midrange. But with the DI seal problems reported on this car by owners who regularly take their cars on the track, I'm reluctant to do anything that might affect the warranty. At least not at this stage.
I know the top complaint about this car is it's 'lack of power'. I traded in a Mazda Speed 3 when I bought the FR-S, which had a lot of mid range grunt--exactly what the '86 lacks. So I understand the sentiment. But I'm very happy with the car. And I think it just goes to highlight how people’s ideas and expectations of performance have changed over the last 2.5 decades. If you look at the weight, the balance, the power to weight ratio, even the wheelbase, the '86 is very similar to one of my favorite cars from my high school days, the Porsche 944S. And back in 1988, did anybody complain that the 944S was slow? So I suppose it's all a bit relative.
That said, bumping the engine up to 2.5 liters for around 230 bhp and eliminating the dip in the mid range certainly wouldn't hurt. 👍
