About right TommyW I have thought Elise too, but am thinking a bit fragile for the track, quirky, and super expensive to fix body panels in addition to getting in and out of.
Tcoat also agree with you. This was the center of my question, although I’m encouraged by a couple of the responses here. I had LWFWs on other cars and they do seem to make a big difference. How’s do the post 2017 changes effect the engine relative to what we are talking here? Difference or hardly noticeable? I am impressed by the community here ... big factor for me as well. |

The best bang for the buck is to get a tune that does away with the factory compromises they are forced to have due to emissions and mileage requirements. Some say a header is needed but the car already has a header so changing to a different one is not going to net you much "improvement". Will make it sound cooler though! Some of the other things mentioned will change how the car feels and maybe make it marginally "faster" but it will still be a 2 lite ... ahhh you get that point by now!

Consumer reports seems to agree that Mazda is currently more reliable than subaru and is led only by toyota/lexus. You can also disable lane assist. In regards to it just being a two liter NA engine, in my experience this car actually picks up a fair bit of power for an NA car from easy mods. A header and tune can net ~25-30 whp and add e85 for another 10 or 15. NA cars typically don't make much more power with mods.

The only detriment for the twins are the bench racers who have never driven one all shouting "MORE POWER!!!!!!".
It goes fine for what it is. Momentum over 1/16mi digs. 2 or 1.6 stock engines are not normally drag race champions. They've done just fine over the years of Monte Carlo rallys, routinely beating much heavier cars with giant engines.

My philosophy on the track is a monkey can push a gas pedal on the straights. If you're a driver then the straights are just a wait period for the next turn. If you're a track driver and just want the thrill of speed on a long straight and see turns as things that are just in the way before the next straight then get a different car. What is that saying? Something like "Straights are for fast cars and turns are for fast drivers"? |

I have a 2018 ts that was e85 tuned with a Q300 catback and it was OK. The PSR UEL header install was next,uel for sound. This, now final power(LOL) mod, really had the most noticeable effect on the cars pick up. It pulls better from 2k all the way ro 6.75 then gives a surprising surge to 7.5k. Placebo?, sound? You can`t hear it with the windows up after 2nd except for that sound tube thing that must go.

It could be argued that engines with character usually have lumpy torque curves. The flat torque curve people look for tends to be boring. Engines with vtec style setups or turbos that boost suddenly tend to feel more fun as you have to keep them in the sweet spot and the transition from low torque to high is exhilarating.
I suspect if Toyota/Subaru had tuned the fa20 to not have it low rpm torque and just been flat until ~4.5k where it currently comes out of the torque dip more people would like it’s feel

I have a 2017 86. I did the headers, flexfuel and a tune. It makes a difference and I’m pretty happy with the car now. It’s not a night and day kind of difference like a turbo or other FI, but it’s a solid bump in feel and I don’t feel like I’ve done anything to hurt reliability of the car much. This is still not a “fast car” that the stoplight racers would be proud of. The next mod is tires. My car came with some brand new, terrible tires and I’m to cheap to just replace them.
