Help Finding Right Part - Turbine Housing
 

Purchased this RE-Amemiya Stainless Stock Turbo Exhaust Manifold FC3S - RHDJapan to replace my stock S4 exhaust manifold because it was cracking. It had already been welded over, so i wasn't going to have that done again.

I currently have a S4 BNR stage 4 turbo with internal wastegate. However now i need a S5 turbine housing that will fit the new exhaust manifold. I emailed the guys at BNR, but they were no help. Ignored my questions altogether and tried selling me a S4 exhaust manifold.

Any help will be appreciated of course and thank you in advance.

200 views, can no one point me into the right direction?

I dunno if the housings are interchangeable, hopefully someone will pipe up soon, maybe have more luck in the 2nd gen section. What would be your loss selling that turbo and purchasing an s5 equivalent? it would be an upgrade at least. They make a tad more power.

Well, you will likely have to find a S5 TII turbo exhaust housing and have it bored to fit the BNR Stage 4 center housing and larger exhaust wheel.

Take apart and measure your BNR to see which option of exhaust wheels you have and you might just get lucky on buying a used S5 BNR exhaust housing that fits.

I had a line on one several months ago when I was trying to decide whether to put my BNR Stage 4 back to normal BNR spec and sell it and the 60mm external wastegate separately or sell my modified BNR Stage 4 as a unit.

So... they have come up on this forum for sale before.

Thank you for the reply. I was hoping to not go down that road. Actually was hoping to find something on aptuning.net or equivalent store. Otherwise i'll have to contact BNR again and work something out.

you are not going to find an aftermarket housing with the S5 manifold bolt pattern. like blueTII said, your best bet is find a blown S5 turbo and get the turbine housing milled for the P-trim wheel. Gpopshop can do the milling for $100 last time i used them
