Anyone actually running the JackSpania/Phoenix-style N54 forward-facing PI intake manifold?
I’m putting together a single-turbo 2008 E92 335i N54 and already have the JackSpania forward-facing 90mm intake manifold with the included PI fuel rail.
I’m planning to run DW 750cc port injectors with a MOTIV ReFlex+ and already have a Precision Raceworks Stage 3 bucketed LPFP. My tuner has said the factory fuel lines are sufficient for my power goal, so I’m mainly trying to figure out the manifold/rail installation itself.
For anyone actually running this manifold or the identical Phoenix/eBay version:
What fittings/adapters did you use to connect the factory fuel feed to the supplied PI rail? Exact AN sizes/part numbers would be appreciated.
Does the supplied rail use standard injector dimensions and did DW 750cc injectors fit correctly without spacers/adapters?
Did you have any fuel-rail sealing or O-ring issues?
What fuel pressure are you running at the PI rail?
Did the manifold have any vacuum/boost leaks after installation? Any ports/plugs that needed resealing?
Does the 90mm throttle body cause any clearance issues with the radiator fan, charge piping, coolant reservoir, power-steering reservoir, or anything else in an E92?
What charge-pipe/coupler setup did you use to reach the forward-facing 90mm throttle body?
Did you retain the factory MAP/TMAP arrangement, and where did you mount the sensor?
How did you handle the brake-booster/vacuum connections and other factory vacuum connections?
Any modifications required for the wiring harness, PCV system, or catch-can routing?
What manifold gasket and mounting hardware did you use?
After running it for a while, have you had any cracking, loose fittings, boost leaks, or other reliability issues?
Pictures of the fuel-feed connection and installed manifold would be extremely helpful.
