Turbo upgrade pictures

[subachad]

Hi guys and gals. Thought you would like to see some pics regarding a MS3 turbo upgrade.

As for me, I'm mostly a Subie guy, but I signed up for this board in 2003 when we bought my wifes MSP. It was great, but no longer suited her purpose, we just traded it in for a 08 5sp Honda Element SC

Anyways, heres a link to the pics. Sorry, I don't remember who he sent his turbo to for cleaning and a rebuild, but the work appears pretty good.

wierd, i just clicked on this after eading the whole other discussion about re-worked turbos on here.

um your wrong. i work for a mazda dealership as a tech i've also put a write up in the how to section on how to remove and fix this problem with the o2 sensors. some how we don't know yet but we're leaning towards the gay design with that big dish shaped washer.

moisture is getting into the threads of the o2 sensor and rusting up. and when you goto remove it the rust cloggs the threads and cause's them to pull write out if you just try to man handle and remove it like every other car out ther. THIS IS NOT THE WAY TO REMOVE THESE SENSORS AND IF NOT DONE RIGHT YOU WILL DO WHAT THEY DID ABOVE AND SCREW UP THE THREADS. we know it's moisture and caused by simple rust because if you use a can of PB Blast like i said in my how to section the o2 sensor with time and patients will come out clean and with no threads pulled. All you guys do your selves favors and read my write up and do this fix ASAP.

I did this fix to my car when it had only 5,000 miles on it and both sensors felt like they were crossed threaded. i did everything like i explained in my write up and both sensors threads were perfectly fine. Like i said mazda does not know why this is such a big problem i'm just going by what us techs think from our experience and what conclusion we can come up with but it's not cross threaded from the factory or done on purpose or from us at the dealerships because if that was the case no matter what we did the threads would always get pulled and messed up. if done the way i wrote up about and how to fix this problem the threads come out perfect and fine and put some high temp anti sieze on them and it keeps it from happening in the future. Anyway i like the write up on the turbo upgrade and i'm interested in seeing dyno #'s on just changing out the turbo with a ported unit.

I don't think the o2 was removed prior to us doing the upgrade. While I am not a mechanic I do have a significant amount of experience working with cars (about 15 years) and understand that exhaust parts are most likely to have damaged threads. The constant heating and cooling, high temps, rust, etc... all contribute to this. As such, I do and did spray it with PB Blaster prior to removing. While the PB Blaster will keep this from happening most of the time, it's not 100%. The most likely culprit is a combination of not having anti seize from the factory, a weak o2 sensor, extreme temps, rust etc... So please don't bash me with your blanket statement saying I did it wrong and also bash others on this forum. I also did the downpipe on xmysacredoathx's car and we did not have this problem.

I do appreciate your input, however if you come accross as preaching or with a holier than thou attitude, people are not going to listen to or respect you.

Sorry wasn't trying to bash anyone one here. yes one of the big problems is mazda does not put any anti sieze on the mzr L3-turbo engine this goes for the speed 3 speed 6 and cx-7. last time i was at class it was said that they didn't because of they were affraid that it could get into the sensor and that mazda would be buying a bunch of $400 O2 sensors that would be failing and have to be covered under warranty. this is a big problem that they didn't do this on these engines and which is why i did the write up and why i did mine asap and is best to remove both your sensors and put just alittle anti sieze on each one so in the future when you remove it you don't have this problem.
The first one i tried i tried just to remove to see what happened and it completely tore the threads out bad. every other one since then i've had to use almost a whole can of pb blast for two sensor but have yet to pull any threads out of the sensors only had one that nicked the threads but no big deal. but if you use PB blast or something like it and take your time and have alot of patients you can remove the sensors and have no problems with pulling the threads out. yes you can always use a tap and die and fix or try and fix threads but my way i've never needed to and tapping holes just takes up to much time and may not always fixable
