Subaru BRZ - turbo ruled out?

[itsnotagsr]

You can guarantee that every Jap tuning company that is left will have their hands on one and be making kits. After all, if you can work out a forced induction kit for stuff like the 350/70Z, which has even less room under the bonnet, this should be a p.o.p. for HKS, etc.

Interestingly I read a Subaru press release that said that 40% of buyers in Japan for the BRZ were over 40. Seems like people like IMOA are a key demographic!

My brain must work differently when it comes to shit like this.

Obviously, manufacturers don't spend $$$ redesigning an engine for space efficiency for reasonably limited production runs to then whack on a turbo system that has to take up more space. Even looking at that pic you can see it takes up more forward space, not to mention width.

[MRMOPARMAN]

Why? Because the inlet manifold is reversed? It's reversed because the engine is close to the firewall where an impreza is not. What's that got to do with space for a turbo?

My brain must work differently when it comes to shit like this.

I think rjastra is assuming the engineers move the engine backwards becuase theres no room up front.

Theres a number of reasons why they did it but thats not one of them.
There will be room for that turbod engine pick you posted.

Just for comparison/interest, here's the engine out of the car with no turbo:



And here's the engine bay, to illustrate the engine placement:

I have been working on subarus for 15 years and can tell you that when they design something they do it with a lot of scope for change and a lot of forethought.
I cannot see how the current subaru turbo design would not fit in the front of a BRZ. The engine is moved back in the bay compared to a normal subaru and the front turbo system fits in every other subaru even with a forward mounted engine.

You are either clutching at straws or trolling.

Just as an interesting point on the issue of can such a high CR engine safely be boosted - the blown 2GR in the JDM Mark X (which may or may not have been internally identical to the one in teh TRD Aurion) ran an 11.8:1 CR

[rj_astra]

Probably clutching at straws. I assume front mounted intercooler. What about clearance under the turbo unit?
It's quite obvious that Toyota/Subaru have made a lot of effort to reduce the overall height of the unit. The turbo unit displayed is noticeable taller overall.

nah, the mark x is rear drive, and runs an NA direct injected 2GR. aurion is FWD, port injection and supercharged.

Front mount intercooler would (likely) be in front of radiator so non issue and the 1.4 turbo is shorter than the 2.0.

He's talking about the "+M" supercharger Mark X: http://toyota.jp/customize/markx/sup...ger/spec2.html

[MRMOPARMAN]

oh.. in that case its still as i said apart from the N/A bit. theres a pic of the motor on the website rezz posted above ^ and its got a clutched supercharger down low on the r/hs of the motor. the aurion uses an eaton on top of the motor. (btw the aurion kit and maybe the hilux kit too are aussie designed)

direct injection would help here?
golf gti uses 10.5:1 and cops 14psi or so from the factory, so low blow turbo shouldnt be an issue surely

[UZZ31]

In a knock down drag out Tsukuba race the STI would whip the BRZ so conclusively... it'd be embarrassing

but different class and such

It'd be embarrassing if it didnt whip it, considering the STi is around $20k more

[SuperDave]

2zz-ge is 11.5:1 and the 'safe' boost level when turboing with stock pistons is about 10psi. Obviously dependant on the tune though.

[Tripper]

Wouldnt running E85 allow you to run more boost with the higher compression compared to 98ron

[noobd]

Yes. E85 has more resistance to knock and therefore allows more boost.

[UZZ31]

You are a genius

"owners can increase performance after they purchase the car, only the manufacturer can produce the low centre of gravity frame"

I fucking want one.

[myliberty]

My brain says wait for a few years, till they are depreciated and out of warranty, then add fasts.

My brain says buy one now, new and reward a manufacturer for having the balls to build a sports car.

You have two unconnected brains?

three if you count the little one.

Most of the space you're talking about is taken up by a ginormous plastic airbox, and that is only going to be up at the top of the engine bay there.

Odds on the engineers said to themselves, "I bet this thing is going to get a turbo somewhere down the line." and would have left plenty of growth space.

So, where does the airbox go for the turbo model? The boot?

[Kaiser]

Off to the side of the engine bay like every other EJ series Subaru ever made?

[nickevans]

It's turbo, it doesn't need an airbox, it stores it's air in the turbo. Deerrrrrrr.

Have we got confirmed pricing for the Aussie Market yet?

[myliberty]

Probably $39000, or $79000, depending on absolutely nothing but some shitcunt accountant.
