That color is extremely close to the Fusion I bought for my wife.

You can never go wrong with a black or white benz. those two colors are best
And I bet they don't use soft ultra thin paint like thubawu, so it actually holds up over time

The wrx is definitely faster. But the mb has power off the line like whoa, I'll race myself next week.

My wrx has so many chips in front it's retarded...

Have a strong desire to slap the new Edelbrock supercharger on the BRZ.

Stock on 91oct only 245whp peak (although much better than stock NA at like 165whp), but makes 90% of peak torque from 3300 to redline and eliminates the dip. I figure E85 + full exhaust would get it up near 280-290whp which is appears to be about the limit of the FA20 if you want long-term, real world reliability and still be able to take it to the track.

Only real negative is adding 30-35lbs to the front of the car. Although you can 21 of that back with a lightweight battery.

My outback is the same way. I think subaru designs the paint on the front bumper to pop off the first time a rock hits it. Mine has hundreds of white dots showing through the obsidian black paint.

I believe that's an electric supercharger? (have seen electric SC's for these but not that brand) Either way, if it's really a boost from 165whp to 245whp, that's a huge jump in power for only 30-35lbs. My supercharger weighs 40lbs with the brackets/pulley/tensioner/SC. Plus intercooler and everything else required to run it.

18psi 08-28-2015 06:53 PM

It's a regular roots type.
Just checked it out. Kinda cool. I'm really not a fan of A/W anything, but you gotta appreciate the compactness and how this and the Innovate both look like they're part of the OEM package. Pretty neat.
I do believe a brz might be in my future when all this stuff starts getting a little cheaper. Though I'm still partial to turbo :)

z31maniac 08-28-2015 07:03 PM

The Edelbrock is apparently only being used 60% with a 3.25" pulley, and there are 3, 2.75 and 2.5" pulleys available.

I think they are saying, assuming you had the fuel system/clutch/cooling to handle it (obviously the stock bottom end isn't going to hold that for long either), the smallest pulley + E85 will get you up around 500 crank hp.


And as for turbo, there are a ton of great kits. Ptuning or the JDL Twin scroll setup would be proper.

Stock Edelbrock on 91 CARB tune.

the CARB legal part makes it particularly interesting

The Eaton 1320 TVS will do enough lb/min to do 500hp? God damn.

18psi 08-28-2015 07:21 PM

I doubt it, but I also doubt anyone would waste time trying to make 500hp with a supercharger on a fa/fb when there's so many turbo setups available that already achieved that.

The Jackson Racing Rotrex kit is CARB legal as well, makes more peak, but obviously doesn't have nearly the tq/midrange of the TVS.

JR also just released a high boost pulley (not CARB legal), fuel pump/injectors/custom tune/E85 = 380whp!!

Of course you'd also need a clutch and you'd be on borrowed time on the stock bottom end. The rods seem to be the weak spot north of ~325whp-ish. Although there are some lucky guys that have thousands of miles north of 400whp.

That's what they are claiming. They are saying it's 60% at ~300 crank HP for the BRZ, so 95% for 500 crank seems reasonable.

when I get bored of my wrx in a year or two I'll have to decide:
1) get something boring like Brain and "grow up"
2) get a brz, make it not deathly slow, and just keep being a child at heart :)

EO2K 08-28-2015 07:27 PM

I very briefly considered selling the Miata and buying a BRZ and tossing my 6258 on it. If someone had been making a CARB legal kit to do that at the time I was looking, things would be very different in my garage right now.

oh no dude don't do that. there's so much more you get for your money with a miata.
the only reason to do it (IMO) is if you're daily-ing it and need dat CARB sticker.
race car = miata still wins

I wouldn't even look at that car if I didn't need to fit 2 passengers every now and then.

Yeah, the other side of me says:

"Keep it NA, do the occasional track day/Auto-X and wait for Subaru to drop a twin-scroll FA25 in a 2017 STi."

I'm assuming they will so they can keep up with the 345hp Focus RS.

18psi 08-28-2015 07:35 PM

If the FoRS is as good as it looks on paper, yeah, they'll have to do something or go the way of the EVO

18psi 08-28-2015 07:38 PM

I also think they are blithering idiots for discontinuing the hatch.
but it's probably coming back soon

Big blowers can move a lot of air. :p
