    Hey guys! Long time creeper so thanks for all the help over the years. So, my sons 2006 M3 hatch after 180k miles finally needs a motor. Went with a 30k 2.5 from a MKZ hybrid not knowing about the compression. Got 2011 Fusion cams, M6 IM and TB. After more research, decided to go with a...

    I’m wanting to do the 2.5 swap on my 08 Mazda 3, I’m also wanting to manual swap it way the same time. I don’t know much about the specifics of the engines/trans. My experience is more with abc. I’ve got years of experience working on cars, so I’m more so looking for issues that may come up...
  5. Stock Issues
    I own a 2006 Mazda3 Hatchback with the 2.3 and its sucking up any oil I put in it. I've been reading that it could be the Positive crankcase vent (pcv) a fix a dealership could do, or nothing can be done to fix it. So with that I have thought about doing an engine swap but I don't know what...

    Hi all, after spending a good few weekends on it I've finally installed a 2.5 from a 2010 Ford Fusion into my 2008 mazda 3, following some threads posted on this site (could not have done it without you guys!) But I still have a few things left to figure out but once I'm done I have detailed...

    I have a 2013 Mazda 3 Sedan, I believe it's the i Sport and I know it's AWD if that matters. At this point I'm more curious than anything but I saw something about swapping the engine for a 13B or 20B rotary. I don't know a whole lot about engine swaps but I do know any swap would take a lot of...

    Okay, so let’s just do a quick run down. I had bought a beautiful 06 Mazda 3 s with a 2.5 engine swap being put into it from a Ford Fusion. I bought it thinking.. okay shouldn’t be to bad, I had done some research and educated my self on the 2.5 swap on a Mazda and it seemed pretty straight...
  10. Mazda3 (Axela)
    I have a 2007 Mazda 3 Sport 2.3L hatchback. While I don’t have the turbo version, however, I have been wondering if I can strap a stock turbo to the motor from the Speed3 and turn it into a sleeper Speed3 or my second idea is to take the motor and transmission from a MazdaSpeed6 with the AWD...

    Hey there, so I just recently got a 1st gen ms3 and it either needs a rebuild or new engine. The previous owner ran out of oil when driving and now there’s knocking. I’m wondering if I should engine swap or just rebuild. And if I engine swap, what should I get? Or should I just rebuild. Let me know.

    SOMEONE PLEASE! :( So this is my 2nd M3, first hatch. I love it. But as fate would have it, the engine (2.3L) of course seized up due to a manufacturer defect I guess, because I always kept it up with maintenance and clean. Never "dogged" the crap out of the engine. Still, ended up blown. I paid...
