      What piston ringlands?!?

      To the poster above asking about the trans. If this 6 speed is anything like the STi 6 speed, it will withstand these power levels. The engine on the other hand? See above tongue in cheek comment about ringlands The Subaru motors have had their fair share of issues at high horsepower levels there.

      I know that STI 6 speed can handle well over 500 hp, I'm not sure if this is the same unit or a different one. The engine is difficult to say since it's all new, there's not really a track record. The most immediate thing that comes to mind in a negative aspect is that the engine is so small, this level of power must put a serious burden on its components.

      The STI engines in the U.S. were infamous for those problems and went through very little change since being brought to the States in '04 even to the current day models. On the flip side from what I've read, the 2.0 liter engines in the JDM cars were solid.

      They've already said they'll run the engine till it blows up. So I'm assuming that they think the stock internals are not strong enough to withstand the boost.

      Yeah, you are right, there are a lot of unknowns right now about these. I have googled a bit about the trans and haven't come up with a solid answer comparing to the sti unit.

      I do know the BRZ/FRS is an open deck block, unlike the old school JDM 2.0 liter block.

      EDIT: Just read a little snippet saying the BRZ manual is the same as the Lexus IS 6 speed.

      Pedantic much? The implication is that the internals are stock which is a big deal. It will show how much the stock motor can take once breathed on a bit.

      Then don't buy a big turbo car? It's a crazy theory I know. The power band is basically the same as stock until you hit 4.5K rpm, and then you are making quite a bit more power than stock stock from there to redline... Keep in mind they didn't even start the dyno run until about 3.7K rpm.

      Not to mention that they will have kits with smaller turbos that still make a **** load of power and spool sooner. If you want to make the power earlier, buy a smaller turbo. If you want the biggest dick on the block, get the GT35R. Who am I kidding though, it's not like any of you even own BRZs or would ever buy this kit anyways.

      Tell that to the Subaru tech at our shop who oddly enough just did his second outback 6 cylinder head-gasket job this week. I'm sorry but your wrong, they are still a major issue.

      Did the cars in question have the updated head gaskets? IIRC, Subaru released a newer head gasket that was supposed to fix this problem.

      stock engine internals are an indication of overall strength of motor and parts. there are plenty of stock block Evo's and S2000's in this hp range too. it more has to do with proper fuel and boost delivery with good computer control. most modern engines are pretty heavily overbuilt. with that being said, this isn't a car that will take you to and from work everyday for the next 100k miles with no issues. still impressive though.

      You mean a newer design that replaces the older design on existing sold cars, or a newer design for the production line?

      And I still think a mild supercharger set up is the way to go whit these cars.
      Superchargers help with midrange and don't create the heat issues of a turbo system.

      I heard that Subaru motors have weak valve rockers...

      A newer design to replace the old ones on existing cars. I believe it was just a TSB and a new part, no recall or anything that I know of. However, I don't own a subaru, I'm just pretty sure I read something about that a while ago. I could be way off.

      Until you push the engine to the breaking point, you don't know where the limits are. Frankly, the sooner they blow up one, the better.

      ....

      So...

      I would spend 5/7ths of my time making less horsepower than a Tercel.

      Then I would spend 2/7ths of my time making (average) as much hp as a corvette from 20 years ago?

      All while getting worse reliability than a corvette manufactured 20 years ago.. While spending as much money on mods as would have bought be a used 6th gen vette?



      Yeah... This is a drastic improvement over the original car.


      You have a funny way of reading dyno's. First, it basically is going to 8000rpm. Second, I don't know what you consider anemic, but losing only 20hp across 1000rpm after peak, is not, especially when that's 500 horsepower. It will feel like it just wants to keep going and going.

      Third, the ENTIRE power-band is higher than the stock car, even low rpm. So the fact that it makes more power up top, and the same or better down low, makes it slow?

      It's over 300 hp from 5000rpm on. the stock car peaked at 200. Every shift will be 100% in the boosted zones and higher gears the rev drop will be small enough that you'll go from like 500hp to 450hp. If you're trying to go fast at 3000rpm with a car that raps out to 8000 you're a dumbass. Downshift idiot.

      Yeah it's peaky, but that'd be a beast to drive, especially with how it winds the power out up top.

      And if you're going to start talking $$ vs reliability vs mods, GTFO now. You have no place in a modding discussion.

      This this this. I know in the ITR community that whenever someone new comes up and says "I wanna boost the B18C5, how should I do it?" there are those who say that the B18C5 has too high compression to be reliable with a turbo, there are those who say tear apart the engine and rebuild it for boost, there are those who say to sell the ITR and buy a GS-R to boost because boosting an ITR is sacrilege, and then there are those who say you can make 350whp reliably on stock internals so long as you have a very good tuner and good supporting mods. The last ones are the most correct.

      I always find it funny that people who own a car from the lowest-rung European manufacturers have the most to say about the superiority of "European" cars. Just because a Jetta comes from the same continent as a Bugatti doesn't mean all "European" cars can be grouped as a whole

      I am not familiar with that, I work on the Euro cars and occasionally Honda's when our Honda guy is swamped. I know the last one was an 07 If memory serves me about 80K miles.

      Im really not sure what your saying here, I am a mechanic or tech or whatever you want to call it. I work on everything from aircooled VW's to AMG Mercedes, I work in a shop that specializes in European and Japanese cars with 4 techs; One is a Honda tech, the other Subaru, the other does the misc. jap cars and I do the euro cars. I can tell you with 100% certainty that Japanese cars suffer a great deal more MECHANICAL failures than European cars. So I am in a good position to argue this point, are you?

      P.S. Jetta = Mexico Bugatti = France; not the same continent. Yes European in design but not assembly.

      I *do* own an FR-S and this isn't for me. I'm impressed with it, but it's not something I'm interested in putting on my car.

      Now the Vortech supercharger, that has my interest piqued.
