IMO...depends on what you want to do with the car after the blower...

im running 19x8.5 all around...
there are pros and cons on a staggered config...depending on the staggered setup...

to me, staggered is more of an appearance mod ie going with a more aggressive look...ive never driven an 8 with a staggered set up..but most say you can loose some handling with it..

I only have 3000 miles on a stock clutch. So it should be adequate for awhile with this FI application. When it goes, maybe I'll just do both flywheel and clutch then. Unless I get an itch, because it may be awhile.

Staggered is not in my plans. I have 18's so maybe 245/40 instead of 225/45.

I guess tires (by preference) and exhaust (hi-flo cat) are all I'm gonna make sure I do prior to contacting Pettit. I was gonna wait on the cat-back to hear some with the Pettit before choosing one. There shouldn't be an issue if I just have the Hi-Flo cat and not the catback yet when I get the SC, right? Anything else that would effect the Flash and tune if done afterwards?

Pettit's site offered a Hi-Flo cat with the Holiday special last month. Did anyone get that option? I was thinking RP Supercat, but Pettit's may be a better option since it's tested with their setup. Depends on the quality of the Cat I guess. Who's did they use, is it their own?

Want I meant is that you probably will not see much of a difference in performance with a lighten flywheel after a Pettit install. If you want it for rev matching---cool, that means you are tracking? If you are tracking go ahead and upgrade the clutch, while you are doing the flywheel. The oem clutch and PP is very good, but while the tranny is out it doesnt cost much to put a slight upgrade in.
upgrade coils asap--but not "needed for install"--BUT do make sure the ones you have are good along with your plugs.
Make sure your fuel pump is good also.
If tracking---you dont want to go out on oem size tires. The rear tires will break loose very easily after a good FI install. Same size all the way around please---for the track. You also will need better pads, SS lines and brake fluid but you may have already mentioned that.
Gauges are a must.
Stock suspenion is actually not bad except for the shocks. replace those for track use. The stock ones allow some really wiggly movements of the rear end under hard braking.
get a good performance alignment--you will enjoy the car much more.
Remember none of this is actually needed for the install(except making sure the coils/plugs and fuel pump are working well and gauges), but an FI kit alone is a BIG change. With cars you change one thing and it leads to having to change other things for the best performance to suit the individuals requirements.
Good luck with it!

im not sure what they use for the high flow

Just saw your latest post--I believe most people are just running a midpipe and not a high flow cat--but for emissions you may have too?

As ive been seriously considering doing the pettit SC. I went and saw the shop in riviera beach, met cam, got a ride in the stage 3.... i remember he mentionned that the stage 3 had every option... except a catback exhaust because they kept getting ruined... I was paying more attention at the time to the banzai and the stage 3... so im wondering if its always an issue or just in that case? I love the sound of my MS catback, and i dont have a stock exhaust so... anyone run into this?

also... once I buy the SC and install... what else am i going to need to buy to get a good reliable daily/autocrosser?
Thanks for the advice.

Don't know about your area but currently there is a visual check to see a cat. - no cat no license. Now you say it could be easy to get around that with friends? Wrong, they are randomly stopping vehicles to check for the cat. The high flow cat is perfect for Southern Nevada. Cali has the same thing but you don't hear much about it.

CURED RX8

Tracking not really in my plans. Just never seemed to get involved with it. If I did, I'd probably be an addict. Good for me, bad for rest of the family.

Even though no emmissions here, I was thinking Hi-Flo as opposed to midpipe for sound. But maybe the midpipe isn't that loud with the Pettit?

AutoX spends most of its time in low RPMs and constant throttle changes.
I think an S/C might actually be a better choice for a dedicated AutoX car.
Of course, a properly size (small) turbo at low boost will work also, but it might be a bit twitchy and somewhat disappointing on the street.
If the car is going to be used in a variety of driving situations, then the choices become more critical.

Probably not where I might make comments to that extent.
FI choice is dependent on goals on careful evaluation.

I'm not busting your *****. I'm just saying that anything I say, no matter how measured or well reasoned, will be taken completely out of context in this thread.

Even without paying your dues, the fact that you've always been respectful to everyone gives you a lot more credibility when it comes to your opinions.

As far as autocrossing, most of the courses (at least down here) are designed so that you can pretty much stay in second gear, with a few downshifts and quick upshifts after hard braking and powering out of a turn. You're in the power band the whole time, and the flat torque curve makes the car a lot less jerky. Autocross is all about smoothness; smooth is fast.

^^ God, I love the fact that I can't see his posts anymore!
So much more pleasant around here.

Nah, that's no fun. So, eff-off!

Auto-X pretty much lives in second, so you would be running from 2k all the way to redline on some courses.
SC tends to give its big "bang" from 1500 to 3k before everything else catches up (except, well, I guess most of the turbo systems these days that make as much or more torque than the Pettit pretty much everywhere).
I don't know, I guess the best thing to do would be to look at the throttle vs. RPM requirements and how much power is required and then look at the dyno comparison for starters.

mysql101

the thing about a turbo is the misconception that you get a crazy jump in power and the car is uncontrollable. If you're able to maintain 3-4k rpm and above, your boost will be consistent (with a boost controller), and thus your power delivery as well.

From what ive seen/read/heard... i can go either turbo or sc and have a good autox/daily... I've been on the fence for a long time now, Im bringing it down to cost and reliability...

So what will i need to buy in addition to the pettit kit to make it reliable? I asked the same question to scott about the type 3, but I dont think I can spend that much knowing I couldve nearly bought another whole car. Pettit seems to have decent benefits for not too ridiculous of a cost. So i need to know what the final cost is going to be. At the rate im going through tires and things my budget is not able to take many more unexpected blows.

Everything you need comes with the kit.

As far as recommendations for mods... if you're going to compete in autocross with this car, you might want to upgrade the suspension, and maybe save up for some lighter wheels.

MazdaManiac

iTrader: (3)

"Reliability" upgrades are the same for any form of FI. So if you didn't like the list that Scott (MazSport) gave you, then you aren't going to like the list for any system.

i want someone to make a twin charged renesis... I would if I had the means! twin screw sc for 1800-4500rpm then decouple with a magnetic clutch to reduce parsasitic loss and let a good sized turbo give me the power up top! hehehe

vw has this setup on a 1.4L 4cyl prototype, don't know if its available for sale yet

So what are the most important upgrades?
Also... noone has answered whether they can run the pettit with an aftermarket catback exhaust or not?

morkusyambo

No upgrades are needed to run this kit as shipped/installed by Pettit. There are, however, a couple of products BHR will be releasing that will improve the kit.

You can run any exhaust you please.

Razz1

That's because it's all your fault.

You post and we look at your Avitar and then misunderstand what you wrote!

Mu ha ha............

Mazurfer

Suspension area upgrades(sways included) are probably worth taking a look at, but not required.
Nothing is required and you can run any exhaust you like.

MazdaManiac

iTrader: (3)

No, not to just get it to run there aren't. (Well, sorta.)
To be reliable, there are many upgrades needed.
That is true of all FI systems.
