Anyone have any experience with Hybrid Performance manifolds?

If the stock manifold is anything like the SR20, it should support ~350-380WHP or so before it becomes flow limited.

Are you shooting for more than 400WHP?? What is the reasoning for sticking to a top mount??

The easy button is buying a used good quality top mount setup and re-use the turbo originally planned for bottom mount.

I want to stick with lowmount because i dont want to change my turbo/wg/downpipe setup.

Id like to crack 400whp and i know the stock manifold doesnt give the full potential to the hypergear turbo i have (bolt on replacement turbo)

I'd say get the stock ones ported then, if people can crack 400whp on an engine with 2 less cylinders and a shit cylinder head with the stock manifold and a bolt on turbo I'm sure it's possible.

As mentioned, the SR can flow up to about 380 WHP on the stock manifold. The RB25DET manifold looks to be log type manifold and not 100% similar to the SR20, but close enough.

Hog out the stock manifold and weld an external port on it and go to town. That EWG port will free up some restriction in the exhaust and allow for a 20-40 more WHP as compared to the IWG setup on a stock manifold.

Don't waste you money on that hybrid or whatever manifold. Spend your money elsewhere......
