    That heatshield on the the freaking alternator is a pain in the ass! Good job guys!

    I was not expecting this to be a video based off Burnaby BC. I just recently purchased a Speed 3 as well which needs some minor work here and there. Another trick I got told if you wanted to prime the system before starting it, is to push the throttle and clutch down completely and crank it. The ECU will recognize that, and just cause the motor to crank but not start. I do this temporarily to prime my chain from rattling on cold start, until the weather gets warmer to replace the chains and VVT acutator.

      Have you done the timing chains on your Speed yet?

      How does that help with the chain tension? Or is it for the VVT actuator?

    Lol great video... as we also made the same 2hr job into much longer. We were on the home stretch and noticed while plugging on the boost controller vacuum hoses... hey what did they say in that video to be careful about breaking expensive brittle part. Yep we broke it. A little MacGyver action drilled the end and popped in a T fitting and capped the extra end and wrapped it up with 3m electrical tape. Seems to run fine although only maxing out at 14.xx psi now with 21 max psi base tune. Previous old bad seals turbo was hitting 19.xx max psi. Anyone know anything specific? Should I just get the Cobb controller now? Thanks!

    Was your high flow downpipe has the cat to pass smog ? If so where did you get it i need one for my 07 mazdspeed 3

      We don’t have smog here so it wasn’t really to pass smog, more to just keep the noise manageable. I don’t recall the brand but it looks like Cobb makes a similar product. My friend who owned the car picked up the part second hand.

      It still had a cat in the pipe we installed but it was also on an aftermarket tune. So no codes

    where did you get lifts? jack stands? :/ I'm prepping to do some installing and those would make a world of difference

      They are called quickjacks. I got mine at costco. Here's a link: www.costco.com/quickjack-5%2C000-lb-capacity-portable-car-lift.product.100460313.html

    The axle on the compression wheel must not have play, it must not move by hand, it will start consuming oil again one day. I know from experience.

      The turbo we installed wasn’t perfect either. It’s seals were okay. It smoked a lot less but eventually blew when a boost controller vac line cracked and sent the turbo to max boost. It grenaded the turbo and we installed a new cst3 turbo.

      Did you guys figure out why you had retard/knock?
      And what was the cause and what was the fix?
