So I have a full-race turbo kit for my FD but I am not able to get the full potential out of my car due to my boost lines melting from the heat. Just seeing if anyone knows of an alternative other then getting steel pipes built for the boost lines. So seeing if anyone knows of a combination of steel braided lines or sleeves that go over silicone lines. Please help, thank you.

Viton tubing with the asbestos heat shield tubing over it.

 

which lines exactly are you melting? often they can be rerouted to solve this.
Otherwise I would just use swagelok stainless tubing for the parts of the line that are in high temp areas. This will be cleaner and more reliable in the long run, and is inexpensive and easy to install. You can get everything you need including tubing and adapters from McMaster-Carr

 

My wastegate lines. They're daisy chained.

 

Thanks guys.

 

That's what I figured. Stainless tube will be fine. I have no experience with viton for these. Do NOT use braided stainless, as the stainless braid will make the line look fine even if the rubber lining has melted, so you could end up overboosting without being able to see any issues.

 

So the link that you shhared, those products should be suffice?

 

stainless tubing should do fine, or reroute the lines

 

Swagelok fitting have working psi rating of around 5,000 psi and have been tested up too 15,000psi st which the tubing burst, the fitting were still intact and operational...

The are awesome fitting can take basicky anything you put them through... Even heard rumors they use these for the high pressure parts of submarines....


I plan to use them on a few different areas of my car...


Will they suffice? Hell yes

Route the lines away from the turbo and any exhaust components. Sleeve them with DEI fire sleeve. Silicone, Viton, or rubber lines work fine as well as they are protected from the heat.

 

Use ptfe-lined 4an lines. PTFE (Teflon) has an operating temp of 500F and is way easier to work with than hard lines. Use some fire sleeve for good measure.
