How much can you do to an Evo 9 without changing the basic car?

In short I want it to remain a nice driving street car. I'll probably put stiffer sway bars on it, but at this point the springs and dampning are about right. I just don't want to screw up such a nice package, but you always want more! Any input is appreciated.

Thanks,
David

 

tell you right now that warr is going to say warrtalon/buschur stage one in his sig.

good to start off with, great power for the price, esp a 9

 

what are your goals performance wise??

 

I wouldn't mess with the sway bars until you've learned exactly what is wrong with the suspension, if anything. I continue to win or place very high in every event with my fully-stock suspension, a nice set of tires, and a great combination of power mods.

 

I'd say there is nothing wrong in a greater sense, I would like to decrease body roll a bit (side to side) without screwing up the rest of the suspension. The car has quite a bit of grip as it is. Like I said (or maybe I just meant to), it is and will remain a street car so I'm not worried about a specific rules package. The bushings feel a little soft too, but I think I'd leave them because the car actually rides pretty well.

I know my question is a little vauge, but I am trying to get a feel for how far you can go with making the car a PITA. This is a different level for different people. Stock it is already there for some. I race cars for a hobby and I do not want a race car for the street. Having said that I wouldn't mind have the Evo be a bit faster than it is.

Maybe a better question is how much more hp can you make without having to mess with all the other components of the car?

 

He's one of the people I was hoing to hear from!

 

BTW what kind of event? Autocross?

 

You will be amazed what a flash alone does to the car, granted its not as fast as one with a TBE, but quick enough.

 

Yes, we do have a lot of body roll, and it is very apparent in my tripod autocross photos, but the car still handles amazingly well. I've seen too many people add things like swaybars without actually achieving anything, although they swear the car handles so much better - the lap times prove otherwise (driver or setup? hard to say).

This question I quote, though, is far too vague. What do you mean by "all the other components of the car"? All meaning the engine internals or all meaning the fuel pump? There are so many things we can do with this car and so much power that can be made without making it unreliable and without doing in-depth mods, but it depends on what your threshold is.

 

That and road racing. I took 1st in SM in the last SCCA event up here in Denver, then last weekend I put down the fastest lap time of any car at PMI (road course) - that included all classes: HPDE, time trials, and racing.

 

Not debating an actual absolute handling issue just trying not to get sea-sick! I'm not looking to change grip levels as they are quite good, just to decrease the side to side roll some.

Fair point on the "threshold" issue and I guess I am not too sure any of my answers will help but let me try. I don't really want the car to be much louder than it is, At this point I don't want to pony up for a stroker motor, although I am not against that sort of thing. What I don't want to do is make so much freaking hp that I need to stiffen the suspension and go to bigger wheels/brakes. I really like the brakes on this car BTW. I do not want to significantly alter steering feel or shifting feel. Not sure if I care if the clutch changes or not. I am not a fan of really light flywheels on street cars. I really don't want to have to put a different transmission in the car. I probably don't want to increase lag. Living in Houston I probably need to pass emissions or find a different shop!

 

Oh yeah, 93 octane pump gas is about it for me for a street car.

 

Cool! SM looks like a fun class. I ran SRF for a few years. Loved the class, never really got along that well with the car though.

 

What the...

You were talking about not messing much with the car, then you started talking about stroker motors, tons of power, new tranny, etc etc. I think it's time to start over. Now, you're talking about a dedicated race car that somehow doesn't have a loud exhaust. I thought we were talking about basic bolt-ons for very little money that don't require touching the engine/head/tranny/suspension, but that give big gains over stock (this is very possible with the IX).

 

Sorry let me rephrase.

I don't want to do a stoker motor, porting polishing ect. When you asked what my threshold was I assumed you were trying to get to what I don't want to do? Like I do NOT want a new transmission for example. Ect. Sorry for the confusion.
