Supporting turbo manifold and and cat back
Posted: Sun May 20, 2018 7:26 pm
This has always been in the back of my mind. But how does everyone have their turbo system supported? I am currently running a bottom mount turbo which is supported by heim joint bolted to a bracket on the block with no exhaust/transmission mount.
I've tried running a few different exhaust brackets to support the exhaust to the transmission, but those all seemed to have failed one way or anotherl. I originally had a SR20 downpipe that had a welded 1/16" piece of aluminum that bolted to the stock exhaust/transmission mount. That broke off at the welds, so I rewelded it but then the rubber piece separated from the bracket; so I switched to a hard heim-joint bolted from the exhaust to the transmission. Wether it was just a weak turbo manifold, or this method caused too much stress, the old bottom mount manifold cracked at one of the runner welds.
Even though I have a solid heim joint supporting the turbo to the block, I've always thought that it would be extra insurance to have another mount supporting the exhaust. Any ideas?
TL:DR: How do you support your turbo and exhaust? Factory? Custom mounts?
