    Yet another thread on P2177 and P2187

    Gen 1, mods in my signature below. 160k Miles and all of them are mine (I bought this car new with 60 miles on it). Runs great, no misfires, smooth even idle but I get the occasional 2177 or 2187 but never at the same time, though. Lately (last 10k miles or so) those 2 codes are getting more...

    How long should NGK Iridium plugs last?

    I put a set of NGK Iridium plugs Part number 6510 in my dude at 135K when I put my S3 on. I am now at 150K (so about 15K on that turbo/plugs and about 5k on corn). I am starting to get an intermittent miss here and there but no check engine light yet. I pulled my plugs today and they look...

    High Pressure Fuel pressure/Fuel filter questions

    My Gen 1 has just about 150K miles on it (I bought it new in 09). During my last tuning session we noticed I am not always maintaining 1700PSI on my fuel rail during pulls. PRV test passes at over 1800 PSI. I have cleaned my dump valve a few times. Could my in tank fuel filter, possibly be...

    Is there a difference between the MS3 and CX7 Longblocks?

    My longblock is a little long in the tooth but not needing any work right now (at 150K miles). I do expect it to need work in the next 50k miles though so I would rather start a slow build now so I am ready to just swap when my factory block pukes. I am not looking for a huge improvement in...

    MS3 Diff fluid?

    I have a few easy questions for some of you that have worked on a few of these: 1) Our MS3 Trans is completely different than MS6 trans, right? I only ask because as I am searching for answers to my other questions, I am only finding info for MS6. It got me to wondering if the MS6 has the same...

    Should I replace my PRV?

    Doing tuning for my down pipe and Tuner noticed my fuel rail pressures are low. I have been watching them for the last week and they are low and kind of all over the place. Idle is about 450-600. Cruising on the highway is about 1500. If am idling (about 450-600psi) and I blip the throttle...

    Anyone ever replace an A/C Clutch?

    A/C Stopped working (as I was driving through Mojave of course, 112 degrees for 30 minutes, over 108 degrees for over 3 hours with no A/C). Put my gauges on and pressure is good. Checked for a signal at the A/C compressor and it's there. 13V to the clutch and it is not engaging. Looks like I...

    What coolant is best?

    About to conduct my second coolant flush. I don't remember what I used last time (at about 65K miles, about to turn 140k miles) but I think it was FL22. Not sure though. All my other cars have always just gotten good ol' Prestone Extended life green concentrate and distilled water. Any reason...

    Is there any value in these parts?

    On my parts shelf, collecting dust, bug carcasses, and cobwebs are my stock intercooler and secondary cat. Ima bout to install a downpipe and will have a perfectly good down pipe to add to my useless parts collection as well. Do these parts sell? It's illegal to sell a used cat in CA so I am...

    Some NEWB E85 Questions

    I found a local station with E85 so I am starting my journey down that rabbit hole. I have read all the posts in this knowledgebase and done a minor Google search but most of my questions are super easy 1) Do we need to do any hardware changes to our MS3s to run E85 (in any concentration)? Lots...

    Tire size GenWon with RX8

    So I've had my RX8 rims on my Gen Won for about 10 years / 120k miles now. I have had 3 or 4 sets of tires on there. My original tires were a set of Continentals and they fit AMAZING. They were just slightly wider than my rims and protected them from any curb rub. Since then I have had...

    Do you guys flush your clutch fluid?

    I'll be running a service on my car soon. It will have 135k miles on it and is still on the original clutch fluid. I don't see anything in the owners manual about changing it. I don't have problems with it, but after close to 12 years and 135k miles I kind of feel like I should flush it out...

    Rang-a-stang's GenWon

    I am not sure I can really call this a "build" as much as I would call it a diary. Current configuration: 2009 GT. Here's my introduction thread: https://mazdaspeeds.org/index.php?threads/hello-mazdaspeed-bretheren.10652/ I also have most of my parts listed in my signature. My wife actually...

    How do I pick a tuner?

    Tomorrow I am going to order a BNR S3, 3 BAR MAP, and Grimmspeed EBCS. I know I will need a tune and have heard Stratified, Freektune, Purple Drank, and Hypnotic know what they are doing. How do I pick a good tuner? I am OK paying a little more to get it done right so I am more interested in...

    Should I replace or rebuild my turbo?

    My troubleshooting is leading me to a failed oil seal on my exhaust side. Car has 135K miles, original turbo, and only a few bolt ons (stock TMIC for instance, HPFP internals). I want this car to last almost forever and am willing to sacrifice some power/potential power for...

    Is it a PITA to replace the shift rod seal?

    During troubleshooting of another problem today, I noticed an oil leak at my shift rod. Looks like it would be a fairly easy fix but I am not sure. Anyone done this? I don't see anything when I search for a thread or how-to... When I say "easy" what I mean is, can it be done from up top...

    Did my Turbo just puke?

    Car description in my signature. I bought my car new and have 135k miles on it now. On a road trip this weekend it started smoking pretty darn bad after about 6 hours at ~73MPH. It runs fine, the oil in the crank case does not seem low, no check engine light. Here is what I am seeing (took this...
