Ahh its that one. Thanks I will rewatch their video. They did a video summing up the costs of the whole thing, and the motor + transmission part itself was dirt cheap and I think it made 200whp on gas pump after tune (using a stock cast exhaust manifold I think). Rewatching for more info Thanks again.

This is what I'm looking at:

Holy 340hp shit. At 9000 RPM, now I would do this all day! Its (after converting to monopoly money, aka CAD) the same price as a built FA20 engine here, if we compare the price of trans + swap kit to the price of a turbo kit, we might actually be about even, for an engine more powerful (or about the same power) with a more solid transmission, lighter and NA. Thanks for the link, Im checking out their offerings and sending a few emails around

its amazing to me of HOW LOUD the aftermarket community is yelling at Toyota/Subaru "hey you put the wrong motor in this platform" the FA20 motor is a trash can

That’s not really a universal sentiment. For every one person doing a swap there are many more going FI with a built engine, and for every one of them there are so many more just running FI, and for every one of them there are even more running bolt ons, and for every one of them there are even more that are stock.

On the other hand, there is a loud group of car enthusiasts who have begged for more cheap, RWD, light weight cars. These enthusiasts got the twins. The Toyota fan boys didn’t get a Toyota motor. The Honda fan boys didn’t get anything. The Subaru fanboys didn’t get AWD. Etc, etc. They couldn’t please everyone making one car.

Inevitably, lightweight, low powered, sports cars often get swaps. The 240 saw a lot of swaps. The RX7 saw a lot too. The Miata continues to be popular for swaps. The twins will be no different.

im talking about how weak the internals are with boost. as well as the cooling issues when taking it to the track

Every engineered object in your daily life is a compromise and the result of a number of different teams trying to hit multiple (sometimes conflicting) targets. The 86 is no different.


Did it hit it's design objective to live it's life NA in 95% of street use cases? Yep. Having the engine survive making 25% more power regularly was not an objective, thus you see the failures when you ask a system to do things it wasn't designed to from the get go. There just isn't the strtength margin in the design to do it. That's not a wrong choice of powerplant for the car, it just wasn't a design goal.


What was a design goal is the fantastic chassis balance and steering feedback. They hit that target for sure. I just want a smidge more power and a bit less weight. If that comes from the K24 swap with similar reliability, I'm interested.

If it was engineered to be no compromise, you wouldn't have been able to afford it.

I've read that the S2000 AP2 transmission can handle 700whp, and that it can't handled 300whp. One thing most agreed on is that the transmission can't handle hard launches, or abrupt changes in engine speed. So if you drag race, you may want to have a spare transmissions ($400-700 on eBay). Otherwise, rolling launches and smooth shifting is the way to go.

I only do track driving with my car (not even registered anymore) and I never do hard launches or power shifting or any of that crap, so I think I should be good then. I also love super light flywheels so I should have to worry about engine speed when upshifting if I just do it quick enough and downshift is all bout that heel-toe (which I have become quite good at). Thanks for the info.

What exactly about the FA20 do you think qualifies it as trash? It's a reliable motor, it's one of the most powerful 4 cylinder engines on the market, it revs high, and it handles forced induction surprisingly well considering its high compression ratio.

Basically, I think for most people its a mix of too heavy for the power it makes, and placed too far foward. Adding FI only compounds to more weight forward. While it works, and as you just said, its one of the best 4cyl engines out there currently, it can be better. At least thats what my problems with it are. I want a lighter car that can corner even better, but I also want more power so I can add more aero to the car, those two upgrades seem to go agaisnt each other. More power = more weight, usually high up and forward, less weight is usually everywhere but the front of the car, so as it gets lighter, the center of mass moves forward. This is just for me, it may not apply to anyone else at all, or it may be a shared opinion.

I think those are all valid points. With a lightweight battery, spare tire delete, and lightweight wheels it's possible to get the car close to 2,6XXlbs and with the addition of header and tune you can get the car close to 200whp especially if you have access to e85. In my opinion that's pretty respectable for a car that costs 25k new in 2018

This seems like a solid swap because in my opinion the K24 is one of the best 4 cylinder engines ever made, but just because the fa20 isn't as good as the K24 doesn't make the fa20 garbage in my opinion.

Yes, it is more robust than ours. I have a friend with a shop that specializes in S2ks, and he has built plenty with the stock transmission holding 700 whp range (say around 600 wtq). Our transmission has been proven to grenade at considerably lower numbers, specially 4th gear and the shift fork.

exactly what i was after. i ripped Fa20 rods apart at 375 wheel with a super charger. i just feel like other brands do NA 4 cylinder motors much better than Subaru. The honda Kseries motor is a beast 300 wheel NA is impressive.
