Cool What are the goals for your car ?

My goal is to build a high 11- low 12 sec street car that I could drive around ANYWHERE and beat it down without worrying about anything.. I think i will be reaching my goal soon, tec II on the way with turbo

What about the rest of you? Any luck reaching your goals?

Currently, my goal is to get my 1.8L Turbo up to 200 BHP. With it weighing in at 2730 pounds this should make it about as fast as a WRX. Once I get that accomplished I'll tighten up the rest of the car some more then start building a 2.2L turbo block with RS heads.

My goals was to maximize the real world, real roads performance of the RS within the boundries imposed by the basic design of the car:

Maximum engine performance over a wide powerband with no loss in driveability. Overall power restricted to the limits of the stock engine internals, stock engine management and stock drivetrain.

Best all around daily driver ride/handling compromise suspension, which is also capable of handling extreme bumps and potholes. No coilovers allowed. Best tires available, but limited to 16" wheels due to road conditions.

Upgrade brakes to keep up with power and handling.

Upgrade interior ergonomics to keep up with power and handling.

Seems to have worked out pretty well so far. Brakes still need more work, though.

I agree with you about everything except the stock engine management. My car drives even better now than it did when it was stock. No 4000rpm hesitation, no seeming lag in throttle response, full use of 93 octane gas, etc.

I also drove it to work this morning. There's not much use for 280hp when going only 5 miles in 25-40mph traffic, but it's still fun.

To nail down the fuel management for 300 BHP. ARGH... Then boost up to about 9PSI.

You guys articulate my Suby goals well, with the following variations.

1) MY93 Impreza L FWD converted to Legacy AWD drivetrain. Stealth and light weight as is.
2) EJ20 installation. Turbo ready, likely able to handle higher boost.
3) STi suspension with some Whiteline aftermarket parts.
4) STi 4 piston front brakes, Legacy rears.
5) 17" and 16" track tires with light wheels
6) 300 ft/lbs wide band torque.
7) Smooth power delivery over full rpm range.
8) Durability as in minor maintenance only for 100k miles

The car should be able to be a daily driver because the fun ratio is very high, but also able to be competative with the Honda/Acura/BMW crowd at Buttonwillow, Leguna, etc. And of course Tombstone!

Items 1 through 5 are complete, and working on 6 through 8.

I am not aware of a better car to accomplish these goals that is available to us. Anybody wish they had started on a different make?

my goal is a low 13 sec possibly high 12's daily driver that is bulletproof. I am building it for driveability rather then all out power. Autocross does't exactly allow the use of 3rd and 4th gear...but the road courses do

I don't know what my goals are exactly, but if someone would get off their ass and make a good, solid synchro'd gearset, they'd be much more clear to me now. I'm getting damn near ready to sell the car, I'm so leery about the transmission. :-/

8, have you looked into the KAAZ gearsets? They're straight cut 1st through 3rd, but fully synchro'd. Yeah, it's a close ratio setup, but you can stick in a different 5th gear to make it a little less hectic on the highway.
I've got one coming for my sti conversion project.. too bad fedex sucks and decided to hang onto them in customs for a few days longer

Question

So if there are syncros limiting the width (strength) of the gears, what the point of putting up with gear whine from straight cut gears? Is this a homologated gearset, or do they use fewer & larger teeth for strength?

My goal was to make my car into a daily driven, versatile vehicle. then reality hit me: I wont be good at anything just okay at everything

so I am happy with just making my car fast enough for me, and comfortable for me to drive everyday (read - my suspension may still be bone jarring, and acceleration may be a bit neck snapping )

I don't believe that it's a homologated gearset..

After reading everything I could on aftermarket gears, synchros, helical cut, straight cut, etc.. I came to the conclusion that the ideal setup for me would be a gearset with straight cut 1-3, fully synchroed. Why? Spur gears are stronger than helical. They do not generate end thrust either. Which has to be a good thing
I'm not of the opinion that you just have the absolute widest gears possible in order to have acceptable strength. I neither need nor want a dogbox in my car.
With the power that my car will be producing, I knew I would have to compromise somewhere, and gear whine is something that I can deal with. Learning to drive a dogbox in traffic is just a bit too much. Besides, I'll probably get a kick out of the aggressive gear whiny noise
Hey, I think that they'll be more than adequate. The manual implies (not that a manufacturer's manual is to be taken as absolute truth) that it can handle up to and over 500ps, provided that you aren't doing asinine things like running a multiplate clutch and doing high rpm drops.

I really don't think anyone who knows what they're doing with a manual tranny is going to break this. Provided, as the manual states, horsepower is not increased "excessively."

Where did you get the Kaaz gears from? I may need to buy a couple sets. Are you planning on putting these in the STI or RS gearbox? Just curious.

I've actually detuned my car somewhat to make it more livable. It's not any slower in a straight line, but since I went back to the stock 2.5RS suspension, I can no longer hold corners quite as well as I used to.

However, my kidneys are thanking me. I drive in the Boston metreo area. Anyone who is familiar with that region of the country will understand.

I've also gone back to stock RS seats. As much as I miss my Sparco Star 2s, I am glad that I can easily slide into my seats while wearing a heavy winter coat now.

But drivetrain wise, I still run 7psi every day on Sunoco Ultra 94 gas and am loving it. My car idles almost like stock, doesn't sound louder than any other factory high-performance car, gets 25mpg, and puts grins on my face every time I floor it.

Actually, I do. If I had listened to myself and just gotten two cars to begin with, instead of trying to make one car be the best of both worlds, I would have gotten a different car for track use, and bought a plain-jane Subaru with some punch (stock RS, WRX, etc.) for a daily driver. Recently, I was able to finally find an example of the car I've always loved since I was a kid, so I might still fulfill that dream, and still keep my turbo RS... just look in the background.

I see alot of you guys are cutting weight from your subys. Besides lightweight seats, hood, trunk lid, and 5 MPH bumpers. What else is there?

For my (my brother's) I would say reliable 350-375hp pump gas car. For MY car, 11s on pump gas. Yes, that is over 400whp on pump gas. I have seen it ................ once.

13.75 ET's, or faster with looks, suspension, brakes to match. Then I'll rebuild my internals (for tons of boost). My car's 3100lbs, so weight is more of an issue. With an air intake I run 16.8@80MPH. Better then I thought actually.
For every 10lbs you remove you gain a tenth (.1) in the 1/4 mile.
I think for every lb of rotating weight you remove is = to like 4lbs of solid weight. Not 100% on that though.
