I just bought an s4 BNR stage 3 turbo off a forum member and had some questions about it as he couldnt really answer any of them. All I know about the turbo is what I read on rx7store. He told me he bought this hybrid from BNR/rx7store without sending in a core. So here are some questions I have:

What are the specs on the turbo? Do all of you with BNR hybrids have AirResearch housings? Is the exhaust side ported at all or just the turbo inlet? How much of a downgrade is it going from an s5 manifold to an s4 manifold?

Here are some pix I snapped.

You people gotta learn...we can't tell you exactly what *#&_@& turbo it just by pictures!

Take the housings apart and MEASURE the &_&_#+&)(@$& wheels.

Well I was hoping people with the BNR hybrids (stage 3 specifically) would reply with their specs. Still looking for input with people who have these.

 

The turbine is a factory s4, the wastegate has been ported quite a bit, the flapper door is bigger, and the front seems to be a to4b/e compressor.

I went on there site and found this,... hope it helps,

Direct quote "The stage 3 upgrade consists of a modified 60-1 compressor wheel, T04B compressor cover package and dynamic seal backing plate and dynamic seal thrust collar. The turbine wheel is clipped to spec to decrease back pressure. The wastegate is machined to 35mm and the turbo inlet is ported. The stage 3 is capable of 34-350 RWHP at or below 15 psi. Will reach peak boost around 4000 RPM."

 

Thanks I already know all that but it still doesnt answer any of my questions.

I'm hoping jrat and usmcjsy will respond.

 

Damn that wastegate was ported a bunch.

 

Are you fricken deaf?
Your question about specs was just answered in a previous post.

Just so you don't get lost.
THANK jonfc3s for that information.
If you have no clue what that means, you're in no position to ask for specs...

Thank you to usmcjsy for answering some of the other questions via PM. If anybody cares AirResearch housings are standard.
