There you go. The subject says it all.

I'm not looking for huge numbers. I have no interest in street showdowns. I just want 200whp+ with good spool-up characteristics.
The ZPI Stage 0 kit seems to fit that bill. I really like the price-to-performance ratio. It leaves room in my budget for an aux oil cooler, clutch and Dezod's part-throttle box. It also means that the LSD will be "sooner" instead of "later".
My only concern is that 60 seconds of Autocross is way more brutal than 14 seconds of 1/4 mile.

Any opinions? Advice?
Thanks!
...and yes, I know it'll put me in some stiff AutoX competition... :D

 

Looks like youve got it worked out. I want a stage 0 myself. Should be a nice level of torque and hp for your AutoX needs. And the partial throttle system should work wonderfully for your application. Good luck!

 

In re-reading my post, I guess I could have been a little clearer on my question:

Will the engine stand up to the brutality of AutoX with a turbo kit lacking an IC?

 

Maybe if you went with a water/meth injection system. That's what I use on my daily driver with a stage 0 and it keeps the temps in check -but I don't beat on the car for 60 second straight. I'm sure with a topped of water/meth tank you should be okay.

My gut says Auto-X with a non-intercooled or after-cooled turbo is not a good game plan. There is a lot of acceleration and breaking but not a whole lot of speed on a lot of the AutoX's so everything is going to get hot under the hood real quick.

 

My thoughts exactly. Definitely go with an injection setup if you cant do an intercooler.

 

I feel like I'm shopping at a big box electronics store. "Oh, you're buying X? You should really grab these accessories." :D

Not complaining, but I'm just more and more realizing the TCO on a turbo was a bit higher than I had planned. Not daunted, though. It just means I need to make sure the car is even MORE bullet-proof. I'll need to drive it longer to justify the costs!
Eric, I just got done reading your thread from back in August on the S0 install + injection. A good read, and it sounds a lot like the route I should take. Up here, a "hot summer day" is 95F in the sun and 100F is considered a "killer heat wave". More humidity or something, I guess.

Anyway, where did you end up with your setup? Are you running with the e-manage? Were you seeing lean-outs at WOT while running Stage 0 + injection (but w/o the EMS)? And with a system like this, is there any concern about water pooling in the intake piping? I know you were going to try different locations for the injection system.

I posted this question because I was really somewhat worried about flogging the hell out of the car.

 

I'm still having issues with the tune -but that's because my car is A/T, so the ECU stays in closed-loop longer than a 5-speed. I'm currently boosting 9 psi with the M2 injection system pulling about 6 degrees of timing until about 4500 rpm. I also converted my emanage to a PSI based tune using a GM 2bar MAP sensor. Car is running better but still not great as I go from closed-loop to open-loop 100% of the time.

WOT will always be good on a tC because in open-loop fuel will always be added to what the MAF sensor measured. ZPI did a good job sizing the MAF flange. Now the stock injectors will run out of steam as you approach 6000 RPM's with the A/T , the 5-speed may not have this limitation.

Water injection pump will stop the water from back-flowing. They also make a check-valve if you have the tank above the pump. Injecting after the turbo yielded the lowest entering air temps. When you lift off the temps will rise -but that's probably okay cause you are not in boost anyway.


I'm really excited about the Dezod EMS and it's ability to control the closed-loop part-throttle A/F. After I get this installed then I can really start to have fun without worrying about a part-throttle A/F.

I also have a DIY FMIC project that I'm still buying parts for -That will be my Christmas project.

It's pretty mild weather wise around here so the car is taking the 9psi rather well -but when summer rolls around that's when the intercooler is going to be key.

I know what you mean TCO of turbo is more than what it seemded initially, I'll be Stage 1 by Christmas...But that's sort of what it takes to do it right and not have to worry about it latter.

Listen the #1 more important thing for a Stage 0 is to use premium fuel and don't hammer too hard unless you are moving at a good clip. In Open loop the car does pretty well until you get to the extremes. So hammer -but don't hammer too hard unless you know what your A/F is when you are blowing past 6K RPMS. Heat soak is an issue with the tC stock, so a non intercooled turbo is not going to do any better and hot inlet temps can promote knock so keep that in mind.

 

Get the Kaminari hood and heatwrap the charge and intake pipe! Maybe get a coating on your manifold and downpipe as well.

 

If nothing else at least heatwrap the pipes. Should help!

 

Heat wrapping was already on the to-do list (that stuff is cheap if you know where to look). And I've been eyeing up either the Kaminari or buying a fiberglass hood and installing some subtle vents. Dunno if the Kaminari will clear a turbo, so I may go with the latter. I just know that I don't want to look like one of "those guys," so it better be subtle. Either way, a lighter hood will benefit AutoX before boosting.

Thanks for the info, gents. I think I see my plan of attack. The only thing that might change my plans would be Dezod's full ECU replacement. We'll see what happens.

 

Vented hood and turbo? The class you're gonna be put in is sure going to make a VERY entertaining scene when a little tC starts tearing it up with the Evos and M3s.

 

Heh. In '01 I used to AutoX with a guy piloting a '97 Subaru Legacy GT. Stock engine (160hp), just suspension mods, and he was hanging with the 944s.

To me, AutoX is the automotive equivalent of fight club. We live in an age of speed cameras and school zones. Just once in a while, it's nice to get out on a controlled piece of pavement and go freakin' nuts. I'm not so interested in kicking ___ and taking names. Okay, well, maybe a FEW names...

 

id like to see how this turns out. keep us updated with your project.
