Spark plugs swapped out then assembled some fuel hoses and I think they turned out great. Used 3/8" Gates barricade shield, oetiker clamps, push-on barb to -6AN fittings, Parker SAE fittings, braided covering, and some shrink tube. I did not want to commit to machine crimped 910 hoses at this time since I might have to revise these hoses later.


Worked though CAI sourcing issues far enough that I will have something to work with. It will need some re-work because I am not satisfied how it all fits inside the fender. This portion of the work is taking longer than I hoped. Needs a 22deg connector and a short joiner pipe. Figuring out a remote fuel psi pickup for the differential fuel psi sender. Once I have that mounted and plumbed I can finish the wiring harness up. Had to order an actual Sumitomo connector since the current connector will not engage the lock on the engine harness.

While I wait for parts to arrive I am looking at reintroducing the PCV valve removed when installing the Crawford AOS. I want a PCV back in the system since this engine will be ingesting E85 on a regular basis. So I need to reclaim the connection on top of the block. My plan is to reroute the 1/2" AOS drain hose over the 6MT clutch housing to the LHS, route down/forward to the engine, add fire shielding in critical spots, 8an barb to 10an fitting, 10an 45degEL to 1/2npt fitting, right into the KBM oil pan bung below oil level (no check needed). If the drain works out I can then pullout the EJ25 NA tee that Crawford used and replace with the Subaru PCV assembly and route back to the intake manifold plenum.

I disabled the overboost feature on the BPV. 1.5mm drill through outer wall and into MAP reference passage. If I was to redo this I would move about 2mm to the left.


5mm drill partway into MAP reference passage. While holding upright to avoid drilling material falling into the actuator section.


M6x1.0 threads tapped into MAP reference passage. While holding upright to avoid drilling material falling into the actuator section.


M6x1.0 stainless set screw L 5mm bottomed out into the end of the threads. Used high temp thread locker then mechanically deformed the threads to seal the port and avoid any backing out.


I do not see backing out an issue since it would run right into the IC flange and could not fall into the engine.
