Turbo Manifold which one to buy?

I'm going with the BNR racing Stage 1 upgrade. I know I used the search button but I was wondering which manifold options are out there. Any info would help. THanks!!!!

With a stock turbo/BRNS1/S3, the OE manifold is fine. If you really have to have one, Street Unit carries DNP and house brand manifolds. They may also have some Steedspeed manis in stock, but they aren't being made anymore.

If I were going to spend the time and money, I'd go with either a CP-E cast mani or a Full Race ProStock.

is dnp good quality? I head steed speed one did not increase horse power.

I don't know why you'd waste your money on a stage 1. It's basically a stock replacement.

DNP's are known to crack. Thin wall material.

Agree about waste with stage 1 BNR. I'd go that route if I was wanting to replace a smoking stock turbo and stay with stock tune. I can't see an aftermarket manifold making any more power under that senario compared to the stock manifold.

Don't buy a stage 1. There is no point especially if your looking for performance improvement which based on your want for a manifold that "increases" hp you are. Do yourself a favor. Buy the s3 for 300 more and forget that manifold which by the way is not going to increase hp. Helps flow, which is not an issue for that turbo.

BNR stage 1 is an excellent "plug and play" to replace the stock turbo. The flow pattern is so close to stock that you can run it with stock ECU or Hypertech. An aftermarket manifold makes no sense with that turbo as it will not produce meaningful gains.

To benefit from the manifold you will need to go with BNR stage 2 or 3. Either will require a custom tune with AP, and Stage 3 requires a larger turbo inlet pipe too, IIRC.

If you haven't done so already and you want the BNR Stage 1, your compatible exhaust power increasing mods will be replacing the stock downpipe and mid pipe with good 3 inch aftermarket dp/rp. Serious power gains with that. And you can stay with stock tune or get good gains with Hypertech or a well chosen OTS AP tune.

BNR doesn't offer the stage 2 anymore. It was a dumb mid-step turbo anyways and nobody really bought it.
