Looks eldritch, protuberant, discordant, and fungous.

sure hope the drive belt can survive the heat lol

That whole set up is art.

wouldn't it just be better to use separate exhaust manifolds each feeding a tiny turbo mounted directly under the engine? Although I guess it sits too low even for that..

It probably would, but that would be expensive, and also very hard to make. This is much easier, and the lag is probably going to be the same. This is a ball bearing twin scroll turbo!

Someone found out that the stock cat produced so much heat that sometimes it would smell like rubber from the engine bay. . . turns out it was the belt, lolololol. This is of course after a track day.

I don't know what any of those words mean. . .

lol I bet, especially are running hard

Yeah, I'm sure it makes more sense financially. The engineer side of me just thinks it looks...inelegant.

Here we have an FA20DIT with a twin scroll turbo... (albeit cutaway for display purposes) from the Subaru factory.

In Legacy 2.0DIT trim in Japan, it has 296 stock horsepower, with a warranty.

Kinja'd!!!

Granted, it isn't as much of a monster, but it also will get replaced during the warranty period, if it goes 'pop.'

No, the the exhaust pulses of the engine are not conducive to a twin turbo set up. I had the reasons described to me in depth, but it was kind of over my head.

I would make love to it if I could.

Saracen > Decay buys too many beaters

Ah, I can see that. I wonder how it can be any different from the Legacy EJ20TT.

I find this visually appealing.

Eldritch: broadly - complicated, magical, arcane, secret

Protuberant: possessing protuberances, bulging, etc.

Discordant: having discord, not harmonious

Fungous: possessing qualities of fungi (in this case, looking like something growing underground)

All would be words you'd run into in books by H. P. Lovecraft, typically used to describe things that were too alien or bizarre for mortal minds to comprehend. Using older English Big Words was something he did so much he gets made fun of for it, but doing that is also a way to evoke that sort of idea just because he did it so much...

I wouldn't go that far, but I might for it. If only I had something to shove it (the engine) in.

How low was compression in the WRX? Like 10.6 or something. It is 12.5 here, and it runs a lot of boost! I want to say the kit can get the engine to about 450whp or around there!

Do you have a Baja bug?

YSI-what can brown do for you > Saracen
07/09/2014 at 17:46

I want to say the EJ20TT didn't have a turbo for each bank of cylinders, but rather a staged turbo set up. Something like this, where the small one would work low down and the big one would take over up high!

Kinja'd!!!

Saracen > YSI-what can brown do for you
07/09/2014 at 17:49

Ah, ok. I just kind of assumed it was a biturbo setup.

07/09/2014 at 17:54

Nope, cousin does, but not me. He painted it pink, but it has a built 2100cc+/- engine and bus transmission. I want one though, or a Fastback set up like a Baja.

12.5:1 compression, high-strung atmospheric cams, and likely at least 2-3 atmospheres of boost... to turn a 200 peak crank horsepower engine into somewhere near 500hp crank horsepower...

it isn't a matter of *if* it will pop, it is a matter of how many minutes at anywhere near full boost, until that thing blows the heads off the block, or turns the pistons into high-speed shrapnel.

It might be fun if you have the money to recycle engines every few months of use... changing engines like most people change their oil...

And for what? to ruin thousands of dollars worth of tires, or to risk losing control of the car, and wadding the whole thing up?

A BRZ or FRS is not built for that kind of power distribution to the rear wheels, and that kind of power with low weight is only going to lose grip. That is ALL it will do... whatever handling prowess the car has... becomes nearly meaningless without grip. Just about anything turning the rear wheels with too much power for the tires can lose grip... before the tires blow, or the prop shaft or axle shafts break.

Seems like a very expensive proposition for a lot of bragging rights, and not a lot of practical real-world applicable performance.

I'd rather drive a real-world fun ~300hp XV Crosstrek with an FA20DIT, and WRX STI drivetrain transplant for that kind of money... If anybody would build that. About as close to a real-world street legal rally car as one could get, that isn't counter-intuitively lowered to the bottom of it's suspension travel.

And I could, and would drive it every day, everywhere, and just about anywhere, for 100,000+ miles.

Oh no I agree. That thing isn't going to last a very long time. I think someone got 20k miles before it went 'slode! All the guys that are more about driving, like autocross, track guys , even just people that like backroad , have a more sensible 230 to 250whp. So about the power levels of the FA20DIT. The engines haven't exploded yet, and they are plenty powerful for such a light car. I personally wouldn't do it, just cause this is my daily and I don't want to take the chance plus it is expensive.

Pretty simple, it's a 4 cylinder, so twin turbos means 2 cylinders per turbo, and only 1 exhaust pulse per engine revolution.
