I am seriously thinking of jumping on the bandwagon!

1)Is the power enough or do you want/wish you had more?
2)Other then engine management is there any other problems with the kit?
3)Has anyone used an rp supercat successfully with this kit?(without backfiring like crazy)

Thanks

I regret installing it myself, does that count? I'm sure it will be worth it in the end though.

Good question. I still have some hesitations on this kit to this day. I LOVE the extra power, and the fact that I get more power from the bottom & midrange. But the Emanage had me pulling out my hair at times. I have pulled it out for something far superior right now. Car sometimes does overhet when you stand on the turbo for excessive amounts of time. 2 things I would change about this kit. Engine management & oil lines. The oil lines were leaking all over the place. Had to swap them out a bit.

I currently am running the RP Supercat on my car. With the hi-flow cat & original engine management the backfires were random & more than annoying, but now with the new engine management I no longer have that issue.

If you are going to drop big $$$ on a turbo kit I would suggest you wait for the PTP unit to come out. If you are on a budget, or want to build progressively than the Greddy kit makes sense. Just make sure that you have somebody that is very good at tuning & turbo installation.

What do you mean when you say the car overheats when under boost for excessive amounts of time. Could you elaborate on that.

1) In stock form, the power is not enough. You'll need a boost controller and a better EMS and then some dynotuning. Even then, the turbo is too small to create over 300whp.
2) The engine management is a BIG problem in terms of driveability. Theres too many dongles involved in tricking the stock ECU. backfiring, stuttering, airpump on after shutoff.
3) My rp supercat has STOPPED backfiring since I installed the new Interceptor EMS. And yes, it was very annoying backfiring even at cruising speeds.

The PTP kit does look to be very impressive but if you get their HKS FCON, you'll have to get it tuned by an authorized tuner which could be far from your area.
Since I'm local, I may switch to this kit in the future, depending on price.

At normal freeway driving my exhaust gas temperatures run about 1000-1100 degrees farenheit. When you stand on it (boost) for a bit the EGT's go up to about 1300-1400 degrees farenheit, the CEL lights starts flashing & you have to back off a bit. Fine in everyday city driving though.

rkostolni

Wow, I haven't had the luxury of having that happen yet. About how long do you need to be under boost before you see your CEL start to flash?

I agree with Fanman that the extra power at low and midrange is great compared to stock. My main issue is the same as most - the Emanage and the fact that Mazda continues to reflash the computer. My car ran great after the M flash - I would have told Mazda not to flash me anymore, which is OK per the service manager at my local Mazda dealer. I know I need a more comprehensive piggy back but I also do not know of any qualified tuners in my area regardless of which one I get. I have found that for simply adding boost, the manual boost controller is OK as long as there was a way to tune further. Although I have defended Greedy for customer service- at least in my case ( I have had a good raport with Benny, who has sent me his first attempt at correcting R flash changes by modifying one of my 2 adapters- this fix needs additional work) I am still not happy with the overall perfomance.

^ditto mostly.
sold mine. driveability questionable. wait

is there a way to get my M flash back?

RX8FOREAL

Unfortunately I just got off the phone with the RX8 Mazda tech at the local dealership and he told me that there is no going back. I told him how bad the car drove after the R flash and totally unrelated to the turbo. He told me the R flash was to correct the amount of oil flow to the rotors for specifically automatics, but the change was made for 6 speeds as well. He was going to talk to the Mazda tech line and told me to call him back later

cretinx

yeah I talked to mine, he said basically I should replace the o2 sensor and get the car retuned, maybe load a new map from GReddy.

le tme know if he can put you back to the M flash.

Aseras

they can flash you back but they gotta dump their WDS and reload it from scratch up to the M flash or before the update with the R flash or whatever. I doubt they will do it just for you.

( once the WDS is updated it only has the newest updates.. it's also the reason that the dealers are often behind on flashes, they never update the WDS, or only do it when they have too... )

The 'R' flash had a part in messing up my oil seals in the front plate of the engine causing me to get a new engine. I'm just wondering why the seals went soon after the 'R' flash was done. With the 'M' Flash it ran great though.

IZoomZoomI

sound like a lot of headaches...

FLybOi drE

hmm...after you guys talk like this....makes me really wanna reconsider getting that turbo...

i still have the M flash and dont plan on getting it flashed EVER...man i really want a turbo!
decisions decisions decisions...

FLybOi drE

hey anyone recommend using emanage ultimate with the turbo?

MadDog

I have the M flash, and I am also one of the biggest fans on this forum of the GReddy kit. I really think staying with the M is important. I have had zero problems. My only regret: that I didn't do it sooner!

FLybOi drE

cool...i keep hearing that people have oil leaks and stuff...is that a common problem for everyone with the kit?

MadDog

I didn't have a single drop.

Also, I think you are supposed to go around only once with teflon tape.... more than that, and you are really cramming too much material in there.

Moostafa29

I keep hearing diffrent opinions about that. I think I went around 2-3 times with my supply line, and still have leaks. BUT, I think the leak is coming from somewhere else, which kind of scares me. I think the turbo is great, but mine may have been damange from being shipped so many times. I will have it check out very soon though. Overall, I'd recommend it, and hopefully I'll be driving mine by my birthday (nov. 29).

I concurr on the "R" flash issue. Nothing but problems at the moment.
I disconnected the buss wires on my OBD port so that the dealer can't flash mine while in for other things (foggy tail light, creaky sun roof).
