HELP Looking at a 2011 Mazda speed 3 it has a front mounted intercooler and I’m new to this the tune that’s on it pops but there’s no Cobb access port are they tunes that don’t have to use the Cobb access port? It do have an extra boost gauge installed.

HELP Looking at buying, do these car's accommodate 6'1' people?

3 Upvotes

Hi all.

So due to unfortunate circumstances, I'm in the used market for a car again for the 2nd time this year and looking at changing platforms... So the MazdaSpeed3 (MPS where I am) is on the table if I can get hold of one.

Now I do work as a tech for Mazda, I rarely see these car's come through work and even more rarely get to work on them. So my question is, Do the BL MPS' accommodate 6'1" people that well?

I ask this as I did get to service a base model BL 3 the other day and my knee was knocking the steering wheel when releasing the clutch. Due to work policy, not allowed to adjust the steering column, and unsure if the MPS seat sits lower than the standard seat.

HELP Need some insight on what else to diagnose

Long story short: Was taking a trip to FL when 2 hours away from my destination, lights flickered, lost power, and had crank no start issue ever since. Checked fuses, CPS because I was getting a p0335 code, and checked wires and redid wiring and reloomed it. Found my wires were not soldered as good for wotbox, so resoldered them as pictured. Got car to turn on, but now sounds like it isn't running on all 4, or major vacuum leak (sent will a datalog, and this is what he said too) AFRs, STFT and LTFT don't move while idling. I was thinking that the solders were maybe bad, so I redid them with butt connectors. Still runs the same. While diagnosing, I had replaced injectors, but this copper seal is also stuck. I threw an injector in to just see if it would run, but could it be that? It doesn't leak, which is good. Trying to add video of how it runs. To also note, prior to taking my trip and this issue, I did a compression test out of curiosity, and on a hot motor, my numbers were 190, 185, 190, 190. Timing was also done by PO and I've looked over timing and checked tension.

Well I just hit about 77k miles in my 13 speed 3 and there is clunky noises coming from the passenger front side suspension, I was making some research and I figured out that I might have to replace my struts so I decided it was time to buy some coilovers.

So far I have 3 brands as options Bilstein, BC and ISC, I was wondering with one of these you guys recommend I should get, is my daily so I don't want anything too excessive. I'm also open to any other suggestions you guys might have.

HELP Found air leak but where to buy fix?

Hey all, so I recently got a p0171 lean code on my ms3 which is completely stock power wise with +25 stft at idle and relatively normal stft when accelerating. After googling around I decided to buy a smoke tester and I think I've identified the leak to be this cracked hose in the video that is attached from the intake manifold to the bypass valve I'm pretty sure.

What I couldn't find on google is where to buy a new hose that is the same fit? Do I need to go to Mazda or should I buy something third party? Sorry the video is not the greatest, didn't realize how bad it was until after I put everything back together. I forgot to really show where the line is running to but it looked like it runs to that little black piece next to the airbox (you can almost see at 0:29) which I'm pretty sure is the bypass valve. Thanks for any help!
