Phoenix Manifold Fitment

So, I am going PI. I got a Phoenix intake manifold and having some fitment issues. I have stock airbox replacement, upgraded twins and stock location silicone 2" inlets. Has anyone installed the phoenix with this situation?

It is clear the stock airbox (aFe), will never work. I guess everyone has cone inlets at this point, which is workable.

That being said, the Phoenix manifold is bigger than the stock, both in terms of width (front of engine to firewall) as well as depth (in the direction of the driver's side fender). What that causes is the rear inlet to go below the Phoenix manifold instead of kind of around it and over it on the backside. It looks to me like the charge pipe is going to be in the way and/or the rear inlet is going to be squashed.

The 2nd issue is that the Phoenix manifold blocks the PCV valve port in the rear inlet once installed. I could probably find some kind of low profile fitting to address this, but it is a problem as well. I get most people probably ditch this part of the PCV system and vent to atmosphere?

At any rate, if anyone has stock location inlets and PCV and has the Phoenix manifold, would love to see pics or get some advice on how this was addressed. I am kind of regretting not just getting the plate. Seems so much easier.

You live in the US. Relocate your coolant tank to the opposite side and use a relocated rear inlet like everyone else with a LHD car

I vote passenger side inlets, specifically precision raceworks. Should fix your issues.
