Here we go again my friends, with yet another installment of MazdaSleeze.. So, on today's episode we are discussing why my '12 MS3 is against me. So for those of you who haven't seen my previous posts, nor care to dig, I bought a '12 MS3 that was fully loaded with no knowledge of what I was...

So I did a Google search and couldn't find a "Buying" guide on MSO. I did find a few suggestions on some other websites, but I didn't find anything that was very thorough. I'm going to post what I have found so far and please feel free to add more. * If it has mods it better have an upgraded...

Purchased @VTMongoose 's 07 Mazdaspeed 3 Aug 22nd. Had the car plated in 2 days. What a phenomenal car this is. Very capble and in amazing condition to boot. Seeing as I've been passed the torch I plan to continue this build's general course. This will be a road course build and has been setup...

Hey there, I’m having a problem with my 2008 Speed 3. When I’m travelling along the highway with cruise control on and I go on a slight incline, the engine begins to burble/misfire after that slight load is introduced. It doesn’t seem to do it under full boost conditions. Only just at low rpms...

I get a crazy engine rattle everytime i want some boost. Knock Retard on AP goes all the way up to 8 and the engine rattle is only audible when a good amount of boost starts hitting. Either than that, engine makes absolutely no rattle when boost is not used. Ive looked everywhere and the rattle...

Hey guys, I really need some help diagnosing on my 07 ms3. Finished the swap yesterday and the car was perfectly fine. Now today it won’t hardly run for sh*t and is now throwing these 5 codes: PCM -P0117 -P0245 IC -U2064 -U2023 ABS -U2023 Yes, I’ve tried clearing codes. Yes, I’ve reset the...

So, here goes nothing. new member of the Mazda forums from the great state of TEXAS.. really my first forum join EVER. Just copped my first Mazda(MS3) 2008 Gen1 not too long ago. Not sure what I should do as far as first mods and all that great stuff, every video I see is something different...

Hello, all. Unfortunately, I'm at a bit of a loss pertaining to an issue I'm facing with my 2007 MS3 and am hoping maybe someone may be able to shed some light. I drove it last Sunday, Sept. 29th to my friend's garage to install a few items: 1. Upgrade the stock K04 to a BNR S4 v3 2. Install...

I'm excited to share with you our new RMM for the Mazdaspeed 3! We took a whole new approach to the design of the RMM and I have to admit, the results are stunning. We have been running a couple prototype RMM's on a beta tester's car out of Idaho and on an employees car (Mr. White) for a...
