Well this topic is for those subura specialist's that know the car in and out. Now that that's cleared up, lets me get to the point.
I want to totaly customize my rs with fully customizable suspension and engine management. Now before you start to get wise with me, let me explain.
I want to have my engine be variable enough to be able to change the HP on the fly with turbo boost. I want to use a system much like the tec 2. What I want to do is have a sub computer, that it's only purpose in life is to manage the variablity of my car. I want to build a panel with several settings. Depending on the settings I choose, the car's handling and hp will chance. Example: Daily drive setting: 210 hp with mild suspension change. Full out rally setting: 450 hp with raised suspension, etc.

That is basicaly the idea i have. Now for some more details. The engine will have to be rebuilt to sustain 450 hp, or whatever num i want. A mechanical bov will be made to control boost levels, thus changing the hp output on the engine. I will use the tec 2 to manage the engine. Using my special computer, I will program the mechanical bov to whatever pressure we want, say 5 psi for normal driving. The computer will then pass the info to the tec 2 using the same deal a laptop would. Thus providing a setting for whatever level I wanted. That is the engine side. I have other ideas but i will wait to share them.
Now the suspension side. I want to build a new suspension package that can all be controlled via the computer. Example, the shocks would be custom built to be able to raise and lower themselves, much like air shocks connect to a pump would do. Other things like sway bars would be built with powerful step motors and light weight but strong materials, like a titainium aluminum alloy, etc. The step motor will be able to move the bar in or out to extend the bar from 13mm to 23mm or whatever. The suspension will tie in with the pre setting panel that will control the engine hp.
So in essence with this I can built an advance subie that can be used for anything.
Well those are some of my idea's, I have many more. I like some of the expert's idea's and comments on this. If a turner likes some of my idea's pm me we can talk about them and see how to make it a reality.

Well I hope this is technical as possible and sparks some of those subie brains out there.

You'll never get past the pickle matrix.

Definately possible.......


The only question is --
How much money do you have??????

Well the engine management side of things seems pretty basic, the TEC-II already takes everything you've talked about into accout. It has boost control, I don't know what you mean about using a mechanical bov to control boost. The TEC-II kit that Shiv sells comes with a boost control solenoid that will control the wastegate for you. As for changing settings on the fly, I believe it already does that. You'll just need to save several different settings configurations. If you want to be really slick, just get an auto PC and interface with your TEC-II using that.

As far as the suspension side of things, I think you are crazy. What you are talking about sounds possibly (want isn't these days), but I doubt you end up with the results you are desiring. Sounds like you'd be adding a great deal of weight to the car, which kills handling. In addition, everything sounds like custom work... I remember that some Porche's used to come with coilovers that were height adjustable from the cockpit, but those cars are also over 100 G's.

Ah didn't know the bov on the tec 2 was controlable. So on the engine side it is possible to do the various settings. Well the suspension if made of lightwieght matterials can be done, just a matter of $$$. As far as money goes I am no where near what it will take for such a beast to be created, but who knows in the future. This is good, keep the info coming in.

Thanks,
MadMax

$$$$$$$$

that's all i have to say...

It is not the BOV you are controlling, I believe it is the wastegate.

And guys, correct me if I'm worng, but don't you need a computer in the car at all times to send a new datafile to the TECII ECU?

For the suspension part go look at the mercedes Clk *** (top of the line one). It has different settings hooked to buttons for city and interstate. Also go look at the Land Rover they also have on-the-fly suspension computer adjustments. Well thats the end of my expertice. Good luck.

MadMax...

I think you should read my posts regarding this. I am in the process of doing exactly this, but am still trying to get prices/specs/details hammered down with vendors.

I have been quoted 4 prices from 4 vendors, Cobb Tuning, CTC Motorsports, B Spec, and Rally Knight. All are within spitting distance of, or north of $20K for a complete drivetrain capable of 400HP+, according to vendor claims. This is with an aftermarket ECU (Haltech E6K or Wolfe EMS3D), strengthened gearbox (BPM or MRT dog gears), in some cases suspension pieces and big brakes, and limited slip differentials front and rear.

The upshot of the vendor's offers is this: I bring my car to their shop after having put a predetermined sum down ahead of time to show earnest and to pay for parts. I leave the car with them, and in 3-4 weeks or longer, I return to a tuned, road ready car. All labor for machining, assembly and installation is included in this quote.

The Haltech seems to be more favored among the tuning community, not to denigrate Shiv's work with the TEC-2. The Haltech has an LCD keypad interface unit that you can use to adjust the ECU with, negating the need for a laptop to tune the car on the fly. I'm not 100% sure, but I believe the Wolfe EMS3D has such a unit as well.

Well Digital_Boy, I was thinking more along the lines of I build a sub-processing unit that will feed values to a engine management system, like the tec 2, etc. I would prob do something along the lines of a small lcd, with a push screen for button use, and use eprom to code assembler language to control, it. Thus it has no boot time and can be reprogramed via the eprom. I would also use whatever the tec 2 intereface cable to transmite the variables to the tec 2.

ImprezaRS dot com you might be right, not sure what the exact term is for releasing unwanted boost is.

I know the suspension can be done, just alot of engineering and $$$.

Bout would you guys by a kit that made you car change personalities with a push of a button??

Well ss far as $$$ goes, hopefully one of my idea's will get me some of $$$$.

Well I'm back to taking over the world.

"The Haltech seems to be more favored among the tuning community [than the TEC-II]"

Really? That's news to me http://www.i-club.com/ubb-files/smile.gif

Your suspension is not impossible but rather MAD.i dont understand why you would waste all that effert in the super swaybar though.first off in cockpit adj swaybars already exist.they dont use the unobtanium alloy with the 02 thin wall thickness though.all they are is a blade arm at the ends of the bar that rotate from vert to horz to decrese arm stiffness (or increse). But if your going to the trouble to build the reactive suspension why not control body roll with spring rate and dampening at each corner of the car as needed? the main problem with supersuspension is it would be a one off with a vast amount of software,plumbing,sensors,and hard parts that would at some time would fail.then you would have to pay someone to build another one.youd be better off buying several subarus and tune each one for differant moods and pick your car each morning rather than your program.
you would probably save a few $100,000

you could compremise and give your local Mercedes dealer about 30 grand for the suspension out of an 2000 CL 500 (no full blown rally mode, but it does have sport,comfort,raised,lowered,and is reactive not passive.)then give a good race shop 10 grand to mod your car so you have someware to put all the naw parts.then give ME about 10 grand to install the parts and make them work (i make a living fixing Mercedes and dismantle and reassemble my 99rs all the time for fun)so who better quallified to build a Subacedes Benzpreza http://www.i-club.com/ubb-files/biggrin.gif oh and almost forgot the 5 grand or so you would have to pay some hack to reprogram the abc module to work with a car thats about a 1000lbs lighter than the CL

Hey William,
Your plan might have worked but..... i also have worked on benzs before. My first car was a 72 280 sel 4.5L V8. I changed various things on that car,stering pump, the transmittion, and various other things. I'm sure I haven't the experience that you have, but I can manage. I also have a brother that been doing suspension work for over 10 years. As far as the programming, well that's what I do for a living, so i wouldn't pay anyone for that. But if you want you can still help me take over the world. http://www.i-club.com/ubb-files/smile.gif

MadMax

ps I like you idea to have 5 different subies for my moods, but I don't have space in the drive way. Or the $$$ for that.

ok... Mad"man"Max,

I have your solution.
1) Lay off the weed, its bad for your brain. http://www.i-club.com/ubb-files/biggrin.gif
2)Close your deck and get a NOS system. Its a inexpensive way to have "on demand" HP.
3)Invest in an air shocks w/ the $$$ you'll save w/ NOS, you can get an inexpensive comp to have pre-set setting for ride height.
(early 90's Supras has an on board comp for suspension settings) - you can rig a cheapo job.
4)buy a upgraded 18mm+ swaybar. Why would you want a 13mm stock one? Adapt to your car's capabilities... any other thought is not worth entertaining! (in other words... know what your car can do with an 18mm swaybar (or better)... and use it! why have your car understeer terribly with the stock setup? Safty? Do you let others drive your car? Keep it simple.

Hey Rich.

That was pretty funny.
Well as for one, never touched the stuff and never will, why waste money on weed when i can use the $$ on my car, which will give me a better high.
2. Nos is not worth it in my opinon, why risk so much on something that dies out and needs to be replaced.
3. Well I am thinking about something a little more high tech then air shocks and a rigged suspension cpu.
4. I was using the sway bar as an example.
And no one else drives my car.
