Blah. Now we're talking severe law of diminishing returns. For that kind of money you could have a 10 second or better turbo car. I'm not gung-ho enough on N/A to do it just because.

Its about N/A power limits!!! Diminished returns my ***, have you drivin a high 200hp N/A 4-cylinder Impreza? Nooooooooooooo... Not many people have either, but the low 200hp N/A cars are nasty as it is.
And we all know that going that fast in a Turbo car causes ALOT of maintenance problems, like exploding tranny's, blocks, and all sorts of stuff... With that much money into a high power N/A engine, it would stay much more reliable

reliable, shmeliabel. I wanna go FAST! Haha, just kidding, that's why the turbo kit comes after I crack the 200 hp barrier with a PEMS. I want to be able to tune well before I add boost, and even then I won't get crazy. Plan on using a small, fast-spooling kit limited to about 250-260. In between I might use nitrous too, but I doubt it since I'm not a big drag fan and it's not wise to keep on the street. One thing at a time. Maybe by the end of next year I will add cams. Everything I've read and heard about the EJ25 points to them as being the biggest obstacle to better power.

Here you go, the nastiest N/A Subaru I know of:
On the web site it says 360hp or 300psi though, Ive seen a JDM magazine with the same car but showing only 270 or so, i'm not sure anymore...

To be honest, I am simply unimpressed with such a high-strung, all-out motor. The 600+ hp FWD turbo drag cars don't do anything for me either. Speed costs money, and all those cars prove to me is that someone has more than me. A 250hp RS-T homebrew RS-T is what gets me going.
I do appreciate, however, that when factory-backed teams dump 6 figures into a race car for a season, it filters down to us on the street, resulting in my 2.5l flat 4 getting me down the quarter faster than 5 and 6 liter muscle cars from the 60's and 70's.

How about shoe horning in a H6 3.0L motor and building that up? Maybe some 12 to 1 compression pistons like the V8 guys? The four throttle body setup works great on any car. The GTI-R Nissan built used them to add to the low end response and it worked great. Of course they also used two springs per valve, a distributor system and it was a turbo motor. Oh the intake manifold was a very clean design as well. From the intake it was a direct line into the cylinders for the intake. The exhaust only made a slight bend before entering the exhaust manifold.

"Borla headers don't make much HP, there's a british company (PDE? I think) that makes a 4-into-1 design that's supposed to be good. "
Do you mean TWE (Tech Works Engineering) based out of Calgary, Canada? They have a 4-1 merge collector header. Apparently very few out there since they are going through some issues to get setup to do ceramic coating.

Yeah, that's them, TWE. I thought they were overseas, but that's good that they're closer. Has anyone got dyno charts from their headers? I would think that headers should make a difference on our cars, the stock ones seem like quite a comprimise. I'd like to see something that moves the placement of the cat converter, maybe removes it, and has the manifold making less twists & turns.

And a turbo/intercooler with all the piping and equipment is a big more than just an 30lbs... Unless you got some really lightweight exhaust piping... (Note the WRX's 100lbs weight difference to the concurent model RS's)
