The 4N-N5X EFR kit comes with a custom motor mount bracket to clear the EFR turbo, heat shielding, PNP coolant pipe, a tab to lower the water pump, turbo oil pressure fittings and line, drain line, single 3.5 DP, 3.5 standard intake. Water reservoir tank relocation to driver side is required. This kit can be configured with your factory EWG or IWG actuator.

Just reviewed your website. 6.5K isn't horrible for a complete turbo kit - but 19K for a "built" engine where you have to source your own block, oil sump kit, and no headwork is ridiculous. You're also talking about 9000RPM and using the stock profile camshaft?
The stock head flows terrible, and this has been known for a while. All you're doing is asking a slower spooling big turbo to use brute force overcome it. You could make 600WHP without a built engine - I know 2 people on the forum doing it now.
N54 heads flow the same as N55 heads:
You can have VAC build a complete engine as well, including higher displacement or changing the rod/stroke ratio keeping the displacement at 3 liters. I assume since they sell heads, they are included in the build if you want it:
Stage 1 starts at $1,300, and supposedly is a small bump in flow. $2,700 If you want stage 2 which already includes an upgraded valvetrain minus cams:

I love the idea - especially as a guy who came from Japanese cars and loving all things (classic) Nissan, but this kit needs refinement.

They have exhaust manifolds. The M2's manifold does flow better than a standard N55 - but who knows how much. It will fit any other EWG car, but will require you to make changes to fit a PWG.
I'm wondering if Pure or anyone else who takes N55 cores differentiates between the M2/X40i manifold and turbo and the standard EWG.
