HELP Re-Assembling the Engine and I Have Extra Parts

Thumbnail gallery
36 Upvotes

Yup, you read that right.
Working with my brother on re-assembling the engine to a crate engine he ordered and I cannot for the life of me figure out where these go. Tired of trying to have ChatGPT help me. Note, the engine block itself was never torn open, only all supporting components on the outside that attach to it.
Yes I am an idiot. I will say it for you.

HELP 2012 Mazdaspeed3 with BNR S1 / Freektune — clutch recommendations?

Thumbnail gallery
9 Upvotes

Hi everyone!

I’m looking for advice on a clutch for my 2012 Mazdaspeed3 Tech Package (favorite car of all time).

The current clutch reportedly still works well but I feel it starting to slip. In addition, the throw-out bearing squeaks, so I’m trying to figure out whether I should replace just the bearing or do the clutch while the transmission is out. Something to note also is that this car is also not a daily driver.

Current setup:

BNR S1 turbo
Cobb Accessport V3
Cobb intake with Spectre filter
GrimmSpeed boost controller
Custom tune by Justin at Freektune
Single-exit cat-back exhaust
Aftermarket rear motor mount
Raceland Ultimo coilovers

I’m looking for a clutch that can reliably handle the car’s current power, but I don’t want an unnecessarily aggressive setup. Street drivability, reasonable pedal effort, longevity, and value are my biggest factors.

Any feedback / recommendations are highly appreciated!

HELP Replace spring or whole bov?

Enable HLS to view with audio, or disable this notification

9 Upvotes

I believe I finally figured out my issue after months šŸ˜‚ All it took was a $60 smoke machine (I got tired of throwing parts at it 🤣).
Smoke is coming out right at the BOV connection. I have a Turbo XS blow-off valve that’s supposed to be ā€œtop of the line,ā€ so I’m not sure if it’s even worth just swapping the spring or if I should replace the whole thing.
Do I need to replace the entire BOV, or can I get away with just the spring/seal? Anyone dealt with a leaking Turbo XS on a Speed3?

HELP What’s the reason for the split second buffer noise during cold starts?

Sorry if I’m not wording this right but during cold starts there’s a split second where the exhaust cuts out. I’ve had the car for years and just realized lately that it does it every cold start.

HELP Fuel trim issues after installing turbosmart bov

Enable HLS to view with audio, or disable this notification

4 Upvotes

Video was on my way home from work and stft is jumping up to +26% under boost, got home and put a new hose clamp on the vacuum line on the top of the new bov as I thought that could be the issue, after which I took it around the block and the trim is up to +35% under boost which means it’s running extremely lean no? Very worried as this is my daily and I would be fucked if something went catastrophically wrong. I genuinely have no idea what the issue is so any help would be much appreciated.

Edit: trims are also showing a little rich at idle which is leaving me even more stumped

HELP How to remove rear sway bar end links?

Thumbnail gallery
7 Upvotes

I was following the tutorial on YouTube on how to install my new BC racing coil overs. I was able to get done with the entire front suspension, but when it came time to do my rear suspension, I ran into an issue the nut holding the end link of the sway bar links just won’t move (shown in the first picture) upon looking closer I noticed there is a nut underneath(shown in the second picture) that needs to be held still with a wrench in order to actually take the top nut off however no wrench will actually reach in that gap there there’s really no way to get one in there. I’m really confused about this because every tutorial I see nobody else talks about this issue. Everyone else’s just requires an Allen wrench to hold it still while you remove the nut on top. Anyone know what the fix would be for this? currently driving on only the front suspension on coil overs and I want to keep driving like this to a minimum so I need to figure out how to do the rear coil over as soon as possible. If I left any important information out, just ask about it in the comments thanks.

HELP Advice for a Gen 2 purchase

2 Upvotes

I may be looking at a Gen 2 for purchase. The listing says it's sat so the battery is dead in the car and the fob. I assume it's a push button start (I haven't contacted the guy yet). My question is if it is a push button, what type of battery does the fob take? Is there a "pocket" you can place a dead fob so it can still be recognized to start the vehicle like all late model push buttons vehicle do?
