Interesting!
I wonder why everyone raves about the K20, but not the BRZ...

Because the k24 makes gobs of torque and revs.

k20=/=k24

And for a very decent amount of time now everyone's been raving about the k20 and how awesome-sauce it is.
This sucker looks like it can keep up, despite the obstacle of being a boxer. That's pretty impressive in my book. Also the power it puts out with turbo is pretty darn awesome so far (referring to the 400+ setups)

I still really like these cars. Haters gonna hate.

Would daily in a heartbeat with a small amount of boost ~250whp

Stock for stock maybe they are somewhat comparable.

But as far as I've read the BRZ/FRS motor is not responding well to bolt-ons. The K20 responds extremely well to bolt-ons, intake, header, exhaust, street- cams will get you a huge boost in HP/TRQ. The same on the FB20 (or whatever it's called) doesn't seem to have near the affect.

I don't want to come across as a fan-boi (I am not) but, in my experience, there is no modern, N/A 2.0L motor available in the U.S. that can even come close to the K20 in many different aspects. Reliability, emissions, fuel economy, power density, tuneability, modability, etc. etc.

Also, there are some stock block FR-S/BRZ turbo engines out there making ~400whp, a couple dyno charts? 400whp stock block K20's are a dime a dozen.

its not as strong. it has much more complicated exhaust piping. it has next to no IM plenum. twice the cam gears and more other parts. etc etc etc.

I forget now where I read all of the downsides of a boxer, but there are quite a few. I'm just sayin
Its definitely not superior or more efficient to an inline formation. Its up-sides are more about its center of gravity location/shape but not power making capabilities

Not really.
Any car/engine that is really popular will have lots of people trying to push the limits of stock blocks and such for "street credit"
Most of these claims are grossly exaggerated by tuners fudging dyno numbers and just general misinformation being spread.

A stock K20 can most certainly take 400hp, in the same way a a stock BP can take 300hp. In most people's hands its a ticking time bomb that only survives because its in a lightweight car that spends most of its time spinning its tires.

Dont forget the K series is over 10 years old and doesnt utilize DI.

I really like these cars, I was merely commenting on all the dips and jumps on the stock graph

What is the deal with this particular car, if you can say? I caught one of the updates that says its time with Edmunds is almost up. Is this someone's personal car or a fleet car that is going to get returned to Scion?

Hah. Yeah, every time I think those horses have been beaten into oblivion, some noob proves me wrong. So I end up repeating them ad nauseum...

Edmunds owns it. Keeping it a bit longer than our usual 12 months so that we can get some seat time with the blower and maybe a do a couple more things with it.

Good to hear. As much as I hate the new format of InsideLine (above your paygrade, I realize), the FR-S project is one of the things that keeps me coming back.

BRZ STi version won't have a turbo. Or even a tune. 100% stock 200hp engine.

$8k more for a carbon wing. Do not want.

I have a feeling that a factory turbo probably won't ever happen due to emissions. There are only a few places to put the turbo, but then you have to figure out where to put all the emissions crap that goes between and after. They have to "x" distance from the ports and "y" distance from the turbo. I can imagine placing them in front of them motor is out because of the heat (and maintenance).

All this thread does is make me think about how much I want to stick a k24 in a lightened miata...

Quote:
Firstly, the bad news. There is no turbo charger. The BRZ tS will sport the same 200hp flat four boxer from the standard edition. It will also carry the same exhaust system as the standard car. Don’t be entirely disappointed though…
I am extremely disapointed...

You mean besides the ones with breathing mods and an E85 tune making 200whp? That's a pretty big gain, my friend.

I'd agree with you anyways. The FA20 doesn't look like it was bred to be an n/a motor anyways...

K20s have been around for a decade. Give it some time to catch up.

Also: 600whp+ 100% unopened motor FR-S.

If this is true I am going to laugh at all of the early adopters who just got shafted. I would be even more tempted to pick one of these up though and boost it.

meh, such is life: everyone with a previous model usually gets incentive to upgrade.

I was talking to a buddy that works for Subaru recently and he mentioned these buggers having tons of issues. Aside from the ecu/cam mis-communication rough idle issue, he also mentioned quite a few of them already had the fuel pumps replaced after only a couple thou miles. They even had a buy-back on one that had hte pump replaced twice in 800 miles or something. Then he also stated that they start eating oil or something after 20-30k miles. Said they already replaced a few long blocks from oil consumption issues.

Again, no idea how credible this info is, but I dont see any reason why he would lie about something like that.

Kinda bummed me out
