My question is which turbo would be the best for pure bolt-on without ECU dyno tuning.

Both sites claim they fit an automatic, bolt-on and 300rwp without additional parts. They are also the same price, price not being an issue anyways, does anyone have experience with these kits and can tell me what system is easiest to install in the garage and will run the best without tuning or additional parts?

Also, I think since the 4 port auto revs to 7k RPMs only, the PUC <=7kRPM may have to be taken into considering.
Thanks again

Where to begin....

No where.

Our turbo system will work on an AUTO, forum member 09Factor has been running our kit for 2+ years.

We can change the turbo to whatever power-band , or driving style you prefer. Smaller turbo = less lag, more low end torque

You will want to tune the car with any forced induction system, or you will blow the engine. Since cost is not a problem just fly out MazdaManiac to tune your car and drive away...

Ah bummer, one site did claim pure bolt on, no tuning. Just caught by marketing gimicks I guess. That was the Greddy with E-manage. I thought I could at least get a preset flash instead of driving the car in.

Anyways, thanks Turblown for answering my question.

The Greddy E-manage was known for blowing engine...

the Pettit is no longer available either...

von: if you think you can install forced induction WITHOUT some kind of tuning, then you obviously are in over your head and not prepared.

I guarantee you that if you don't tune any / every system out there, you will lose a motor. The E-Manage was infamous for this.
I've said it for a long time, Forced Induction (turbo or SC) doesn't kill motors, bad tuning kills motors.

As for additional parts; I would honestly recommend you look into certain things regardless of which system you pick.
Ignition Upgrade such as BHR
AccessPORT for tuning (will work for either)
Gauges - you WILL want to monitor certain parameters such as AFR, Boost, etc
Pod for said gauges
Midpipe since you'll quickly cook the stock cat
Cooling upgrades depending on where you live such as radiator, water pump, and thermostat
If you go with a turbo, you'll need a boost controller.

those are just what I would consider the basics.

Interesting, because it's listed FS on their website and I got as far as putting in my debit numbers for the Petit, just for test. So the MM upgrade is unavailable too?. Must be the economy or too many Rotaries poping and lawsuites.

the MM upgrade isn't available due to supply issues.
There's people still waiting for kits that were paid for a LONG time ago.

I would suggest calling Pettit; I keep hearing conflicting stories as to whether it's actually available or not but last I hear they hadn't made another batch of them so even if you could order one, it might take a while.
I'm not sure though, call them on Monday and try to get a definite answer.

I called Cam 2 weeks ago, they do not have any blowers for their kits. If it has changed I would be dissapointed they didnt e-mail me to let me know

I doubt it's changed, probably just an outdated website.

I think I decided to go Turblown based on the fact that MM is familiar with the setup and can send me a tuned system with the access port purchase. Maybe I'll have the first 300rwp auto. Or not

von: you still don't get how the tuning works, do you.
it will take several tunes to get your system working properly, MM can't just send you a "turblown turbo" map and have it work perfectly on your car.

That is what Greddy tried to do with the E-Manage and quickly learned that One Map does not fit all.

MM can definitely tune your car but it will take some input from you to make it work properly. Please take a look at his website and more importantly his MM Calibration service thread so you can fully understand the process and make it a smooth experience for all parties involved.

You are correct sir. I don't get it.

How far is MM from San Diego. Tried googling them, no contact us. I don't get that website. Are they a strictly online tuning shop?

Phoenix, AZ.

MazdaManiac is near Phoenix, Arizona. 6 hours away. He does travel for tuning, he was just up here not too long ago. He will street tune also, doesn't have to be dyno.

I just purchased the unit.

Wow I can't believe they can drive to SD for the tune. Interesting. I guess I wouldn't mind driving 6 hours. Depends what I'm doing and if the base tune can get me there.

Thanks guys

I'm sorry, but I see a blown motor in your near future. I'm not trying to be an ass. But, you sound like you just want something to bolt on, that give you moar powa.
Do you understand the dynamics of how a turbo operates? Would you recognize "DANGER TO MANIFOLD!!!"?
This isn't GT5, where you buy parts and add them to your car, and all is tickety-boo.
For the love of all rotary engines, do your research before you jump into this. No need to rush.

He is in good hands. He is not the one doing the install & Jeff is doing the tuning, 300rwhp is cake-walk on these cars.

Hmmm subscribed.

I don't know what injectors you have or plan on running. But for 300whp, You will need at least ID 2000's for the secondary injectors. Even if you uncap the 440 secondaries they stop at 880. so still not enough fuel.

When i did this on mine, i was fuel limited to 8psi. Anything over that, she went lean really quick.

EDIT:
von, between the Turblown setup and MM's tuning you have nothing to be worried about.
The first one Turblown built was for me, and its been running fine for close to 2 years. MM did the tuning.
quite rock solid and HAULS Donkey Butt!

I believe that 100%.
I just felt the need to be the devil's advocate.
Makes me feel like I should have just "bitten the bullet", instead of immersing myself in hours of research lol.

I don't know why people think you need to be an 8club fanboy to purchase a turbo and It's not like simply knowing how a turbo works will keep your engine from blowing up. A business like any other is there to help the customer make informed decisions, like the banks did in the pre realestate boom, no forum pre-reqs/post count necessary.

And I do beleive my engine will blow, but look at all the 8s that blow with no turbo at all. It's just a crapy car. One that I like.

09Factor,

I hear your're the Auto to beat :)

I was given the injector upgrade by Turblown during the purchase. Not sure if it was pri or sec but I'll cross that bridge when I take it to MM. Also have the Access Port.

...... hmm

I'd say 280-290 is easy. 300 can take a little more work to reach. Also the OP has an AT and not sure we have seen 300 obtained.
