rebuilt PG or PTP SST ???????

[sparkplug]

Well I took my car to the garage the other day and guess what my turbo is gone. I brought it in since it was starting to smoke blue. I would normally get just black smoke but now I was getting a really nice blue cloud.

So my dealer is really great. They are allowing me to put what ever turbo I want in the car or replace it with a stock one. Of course if I go anything other then stock my warranty is gone. I have 40,000km on the car and it runs great but now the decision is do I get the Rebuilt PG K04 or do I get the Rebuilt PTP SST K04.

There is a guy on another forum that claimed 330hp with exhaust mods only using the PTP rebuilt but I am wondering who else has experience with the rebuilt turbos to know if they are worth it and which one would be a better option.

screw the lil k04 by a gt30r =D

why don't you want to go bigger?
warranty?

It does not seem there are many tuners experienced with the Mazdaspeed 3 out my way. Maybe that is a factor. One might need to be custom tuned for the bigger ones. adding fuel etc. i suppose. But if you have the tuning tools in place, and a solid mechanical base, upsizing the turbo? well yes. heck yes

Well if mazda is going to be replacing the turbo for free just get the stocker and resell it for funds toward something bigger.

Well I was afraid of the big turbo since the success rate on them seem to hit and miss.

My warranty will be done the minute I put anything but true stock so no worries there since i am willing to say good bye but I also do not want to blow up my engine.

So I do not see any sort of path to a successful big turbo right now. I see a few that have tried it and there are many that have blown engines but I have seen many of the reworked turbos and I have not found any that have blown there engines yet. Maybe I am wrong on that one but I have not found any.

So I want to change the turbo with something better but I want to have something which is safer for the engine then a big turbo where there is no real over all solution or silver bullet to making it work properly.

I have a pretty good deal of mods and my car runs flawlessly without any issues at all not in winter or summer so I want to keep that same workability with my car and it seems the rebuilt turbos is the way to go.

I was thinking of doing the rebuilt turbo with a 3" inlet pipe and a standback to add fuel where I need it to make sure my AF's are ok as well as running the car at 19lbs of boost which seems to be safe on our cars.

Enjoy!

remember that 19psi on the stocker and 19psi on a reworked or larger turbo is not the same thing.

19psi on a stock turbo might be 'safe' but once you put a turbo on that puts out 200-300 more CFM, 19psi all of a sudden gets pretty dangerous without proper tuning.

Yes agreed so I have to say that this is the scary part of getting a new more efficient turbo. Even with a tune how do you know where the breaking limit is ?

All my mods so far have been paved by others who had great success which is great since mine has worked out perfect. Now on the new turbo side of things the water starts to get muddy to know what is safe and what is not.

I know that True-boost has a PG reworked turbo and he runs his I think at 20psi without a tune on it. I am not willing to do that but I figure that if I use the standback to keep my AF's in check by adding fuel where I need it and I will not add any timing since I will let the stock ECU decide that one I should be pretty safe and able to have a successful upgrade.

What do you think ?

enjoy!

Where can I read up on this Ptp?
Thanks

the name of the company is pt-performance so just add the triple w and end with the .com and you are ready to go and read about it.

If your car is stock and blowing blue smoke...I would suggest getting it replaced with OEM stocker. No reason to lose your warranty because of Mazda's Incompetence.

I think the reason why most people are having problems with upgraded turbo's is because of 2 related things.

1-Most people that go with upgraded turbo..have chosen ones that spool up fast...around 3k rpms.
2-The speed3 & 6's ackillies (sp?) heal is that there is not enough fuel down low (below 3500rpms).

Once you add above together..You get lean spikes that cause detonation detonation down low...

And once you open up the intake & exhaust..You get boost spikes down low which mean rods out the side of the block.

The majority of speed3's & 6's that have blown..Have been down low in the rpm band. Not uptop due to much power.

If you really want upgraded turbo..I suggesting going with something that begins to spool above 3500 rpms.

The GT35R is a good option. Another could be a T3/T4.

Hope this helps.

interesting-- now is that lean spike on the low end due to bad tuning or the notorious bad fuel pump? Is there anyway that you can monitor this lean spike because I am constantly looking at AFR and fuel pressure and never see these little dips or spikes.

I agree though it seems like the most people are popping motors with a stock or reworked turbo.

Do yourself a favor and just go with stock! Less headache and the car is still a very capable performer right out the box. Matter of fact, tell them to thrown in a Mazdaspeed exhaust or atleast discount it for you and then call it a day. If not tell them to give you some additional assurance and throw in an extended warranty incase something this happens again.

The down side of the stock turbo besides that it fails, Is the compressor map shows little ability much beyond 6000 rpm. I would like one that, when tuned with added fuel and such could run up a bit further the tach. but at near stock the little K is ok imo

 

[sparkplug]

Well I was all set to do the deal with a new reworked turbo but I decided to call my dealer again to get confirmation that the deal for the labor being free if I put another turbo and that my warranty was gone and the guy said no can do buddy. If you want another turbo you will have to pay the labor.

So with that being said I like the idea of getting a catback that jaydubz threw in there since I don't have a cat back and it might be a nice addition that does not cause to much of a headaches. The car is currently very fast but power is an addiction you always want more.

So close but yet so far. I will have to wait a little longer to get a new turbo in the car but if it starts to smoke again I will have a better argument since then it becomes a reliability issue where I cannot trust there turbos etc....

thank you for all your input.

Hope it works out alright. let us know please if they can throw a Mspeed cat back in for your troubles!
