Hello,
Not spam, I own a 1994 Mazda RX-7 and my second turbo is not working so I decided to do a ton of research and also document and video the process of fixing it. This is the first video. I am always open to suggestions and feedback from get fellow owners and the community.

Good stuff there!

Personally I've been able to use silicone vacuum hose for any of the 3.5mm rubber hoses. Good thick wall stuff won't kink on you. Even if the bend is tight it should allow airflow.

The SVH you got looks great, if it's 3.5mm, fits tight, and has that thick wall, you are good.

I posted a zillion years ago about a silicone replacement for the OEM hoses to the ABV/CRV. The OEM hoses will die again on you, Mazda just used a grade of rubber that can't handle the insane heat there.

One thing you may want to show is removing baked on stock hoses from a solenoid. Get a lighter and an X-Acto knife, use the lighter to warm up the end of the hose, cut a slit in the hose, then rotate it to break the seal and pull off. Works great to get those baked on hoses off without destroying the solenoid. You can also use the long candle lighter to get down in the rat's nest if you need to.

Looking forward to the next part and hope you got it fixed!

I fixed the secondary turbo issue. It was a challenge, but I wanted to follow up. Here is the last video.
