Simplified rats nest & layout change.
 

To improve injector & OMP nozzle's maintenance, I replaced stock rat's nest.

Removed rat's nest & solenoid valve bracket to be reused.

Moved solenoid valve position upwards of the ignition coil. It needs to fabrication attachment brackets. (simple angle shape)

Modify the harness to fit the changed valve position.

UIM(JDM version) assembled figure. This modification has made the maintenance of injectors and OMP nozzles much simpler.

USDM UIM may not be possible because its lower shape is different from JDM.( not confirm)

Thanks.

Nice! That's a pretty neat way to do it!

Yeah, this should work on a US car. The inside of the LIM is pretty much the same.

I am really envious of the new-looking brackets, fasteners and hardware on your engine. Not all corroded looking like the ones on my (low mileage) FD. Oh, and the layout looks very good too!

I nice single turbo is a better option.
