Why do forged n54 internals come up in any thread regarding turbo upgrades or big power, even in an n55 thread?
Do you guys say you have forged n54 internals at a job interview, or your 10 year high school reunion? They're not even forged with the exception of the crankshaft. Lol |

^^ That is a fantastic article on the 7163 vs a ton of other turbos. it holds 25 psi no problem on that STI, 2.5L hits 20 psi by almost 3000 rpm, we should see even better spool than that! In for more updates !!

Our selections are based around the options for the BW EFR Twin Scroll Internally wastegated housing in the B2 frames. This limits us to the EFR7064 for 550hp, EFR7670 for 650hp, and the EFR8374 for 750hp.
At some point we may convert over to external gates (for more options), but initially feel that the simplistic nature of the internal gates will help keep the install and component requirements minimal (yet entirely functional). And besides it seems entirely plausible that these options will exhaust the N55's potential in strength as is anyway. Rob |

Not officially on hold, just been swamped with N54 turbos the past couple months. In which case that is revenue (with paying customers wanting products) whereas the N55 project is expense (will not see a penny until completely done and tested at our expense), so have to do the smart thing for now. In the meantime another N55 turbo option is/was expected to be tuned a week+ or so ago, so we expect that will be soon. It will be interesting to see how that goes, if it pushes any limits of the other N55 systems/engine/etc of which will help determine how viable an even bigger upgrade will stand to the platform. Simply prioritization's for now, but this certainly is not off the radar entirely. Rob |

I'm holding out for your upgrade! I like a completely separate platform, built from the ground up, the manifold and setup as it stands is inhibiting the engine gains plus this opens the door for bolting on a different BW turbo down the road as well, and perhaps an external wastegate if necessary. Good luck and I'll be glued to this thread
