I was not even a fan of this car and thought it was useless until i saw this video..
I think from a handling/balance perspective you'd certainly be in a better place, but even with its light weight, 350rwhp still isn't comparable to 650rwhp, and neither are 11 second runs to 10 second runs. Still, it's great to see this other platform taking off so quickly. They sure are sharp looking (both the Sub and Scion versions.

How many e9x 335s have done 11.2 or less, much less trapped 127+?

Whats truly amazing is that in 6 months of development time they are reaching similar levels of performance that has taken our platform 5 years to get to.

Does anyone know if Subaru or Scion provided tuners pre-production models specifically for the development of after-market forced induction systems. Ford did this with older SVT models so they didn't have to spend money on development or warranty the parts, yet they would be able to see whether the setup would work and work reliably. That may explain why they are making big power already.

Scion didnt really give any cars out early aside from a small handful, but none dide anythign with turbo kits that i know of. The tuners just bought them early on and started messing with them.

Toyota/Subaru engineers said they want to focus on the balance and steering of the car first because those are hard area for owners/tuners to adjust once the car is designed and manufactured. One can only compensate for initial design so much in those area but you can always get power later

His point is don't knock on something without giving it a chance first. That was quite obvious what he meant.

I'd imagine the N54 is a vastly more complicated engine being controlled by much more sophisticated controls. That's not to say that what drives the BRZ is simple. But look at the markets that follow the cars as well. I'd fully expect much more R&D in a shorter time frame into a car that's 1/3 the cost of a 335i new, because there is probably going to be 3x as many of them on the market in the longer run.

Aftermarket development, especially quick development, has always followed cheap power. Look at the Mustang and LS market. Some of the cheapest power you can get AND some of the biggest variety in aftermarket parts. Heck, one company had a blower for the new 5.0 Coyote motor out within like 2 months of the 2011 Mustang being out.

The fact that there aren't a ton of 335i's in the low 11's doesn't negate the fact that there is a wide gap between a car running low 11's and even high 10's.

I'm not, by any means, diminishing the awesomeness of this development for the BRZ, but in the same token I don't think it's yet in the same league to be viewed as a replacement for what a 650rwhp 335i can deliver. It's quite possible that in another 6 months they'll be there. Just have to wait and see I suppose.

By that logic, you should go ahead and try gay sex. Don't knock it until you try it

I think it goes without saying that spending 6K on a turbo kit and then blowing your engine would be a pretty costly experiment.

I knew this engine would be capable. Heck, do a low compression build and see where that gets you. Subaru themselves has already turbocharged the FA20 and has resulted in great power gains and nearly twice the torque it had NA. For those who don't know what I'm talking about:

http://kaizenfactor.wordpress.com/20...e-fa20-engine/

If money wasn't an issue, I'd drop in an EJ25 Cosworth longblock, GT35R and an STi gearbox. This chassis is more than capable of handling that power. The engine bay is plenty large for that, heck it's already accommodated a 4U-GSE from an IS-F and a 2JZ-GTE from a Supra. I've heard people want to drop LS1s into this tiny thing This car, as I said in the past, is merely a platform for modifications. The engine may be lackluster, but apparently there is huge potential to be had. Looking forward to what tuners do to this car.

I'm pretty sure the motor in your own car was never meant for boost but is very successful when boosted to say the very least. Not sure your point.

Not sure his point either. Anyways, i am impressed and look forward to seeing what these things could do!

Other than maybe our low psi builds, boosting an 11.5:1 $25k motor on stock internals (despite how well the S54 is built) is not ideal. Slap a turbo with huge psi on a stock N/A Scion to attain 350rwhp... Get the popcorn. It's just a matter of time.
When they come out with their 'STI' version down the road, built for a turbo (like an N54)... Different story. That's my point

drop a head/cam/intake/header ls7 in this thing and lets really start kicking some ass.

seen a few on the road, I think they look good.

Toyota is already offering a supercharger kit for the FR-S.

I think a pushrod V8 in an FR-S is just wrong. Call me a purist or whatever you want but to me a 1J/2J, VQ, or even a built 1U.

A 1UZFE is not a bad idea at all. Comes in lighter than a 2JZ, can be mounted further back in the engine bay, and is cheaper. Now it can't have the 2JZs power capabilities, but these engines have been receptive to mods. I'm sure when the BRZ/FRS owners warranties run out, we will see more ridiculous swaps. Exciting stuff.

There are already a number of swaps, like the EJ25, 2JZ and 2UR, the V8 from the IS-F. But IMO it is not very good to swap anything more than a V6 or F6. The current en is an F4, so it is very short. Don't know if the Chassis was built with longer engines in mind.

You are assuming you will blow the engine. No one knew how strong the Supra engine is until people started to experiment with it. Experience is key to life, not money.

With the NA Supras you had to change out the headgasket to obtain a lower compression ratio and that was about it. This engine is a mix of Subaru & Toyota technologies so it's anyone's guess.
