I personally feel we've steered too far away from the raw beauty that is a Roman vs MS Paint graph.  

The majesty is there with solidworks, but the raw emotion has been lost.

It's not a graph, but, its MSpaint used for something MSpaint shouldnt be used for. Which is in keeping with the spirit of things.

The APS that came with me K24 is a box that sits in the engine bay being feed from a normal cable pedal. Means you can put the box anywhere and just get a cable to suit

Yeah the Altezza throttle is like that, it has the APS on the throttle via cable pull. 

But looks a bit tidier to not have the throttle cable and extra wiring in the engine bay.

Thanks for setting out the FP versus injector duty cycle considerations. That was an interesting read. The external AFR option, usually mounted remotely to the fuel rail is also a space hog.  Prefer something neat and OEM like the Bosch 4 Bar FPR.  Might work for you if your current direction of travel with more injector duty time etc etc doesn't play out

Probably wont work in your application but this site offers a Bosch Regulator housing adapter that is designed for  the Bosch FPR. There are probably similar offerings out there.

Hey that's cool! Thanks for that. 

Someone also pointed out to me that the LS1 FPR, although it sits externally, is a factory 60PSI one. 

In factory form it sits close to the gas tank and feeds a dead head fuel rail, so it's kinda like what Toyotas etc do internally inside the tank. 

I'm confident that it'll be fine with the lower pressure though, as the factory Redtop 3S injectors are a slightly lower CC rating and from factory runs at 43psi.

Must be able to remove rear coilpack with the factory bulkhead drip tray thing in place. Cutting this, is a bridge too far in terms of losing street car feel.

Remote coil packs are a thing!

True, but I would prefer to keep the simplicity of packaging and troubleshooting that you get with coil on plug. 

This will be very close to the point of sump hitting crossmember anyway.
