Frequently Asked Questions
Will this manifold fit my turbo setup?
T4 flange is standard across most aftermarket turbo housings. Verify your turbo compressor uses a T4 inlet before ordering. If your turbo has a different flange (T3, T6, etc.), you'll need an adapter.
Do I need to gasket or weld this to my engine?
Mounting method depends on your big block configuration. Test-fit the ports first—some setups use gaskets, others require welding or studs through the block. Have a gasket material and fasteners ready before installation.
Can I use this manifold out of the box?
Stainless castings ship as-cast. Inspect for rough edges inside the ports—light finishing may improve flow. No painting required, though you can coat it if you prefer.
