4n Motorsports Bottom mount Single turbo kit

Hey all, seems 4n Motorsports has entered the n54 arena with a really nice looking Bottom mount kit. It uses a Borg Warner twin scroll i believe with almost equal length headers the kit sounds and looks monstrous! Has anyone got hands on with this kit yet? im kind of interested to see what they are like or if they are cracking headers or anything

Extremely interested in this kit as well, especially since Speedtech isn't offering their internally gated EFR e-chassis kits anymore.

I've got a couple emails in with these guys asking some questions, but am still waiting on some answers. Since these guys seem to have started on f80/s55 platform, I tried posting over on an s55 forum to see if anybody had any experience with their kits, but no responses yet.

Note to n55 guys: on there website, they don't show n55 kits on the front page - you have to click on the n54 kits to get there, and see that he's got kits for n54 and n55.

Been around for a while, never really committed or communicated their development for the N54 despite releasing a kit eventually so I can't comment on their business or kit quality.

How does this compare with the Pure stage 3? N55 is fairly well naturally suited for a big single bottom mount, given that is the original architecture of the engine.

I see they stopped their presale intro pricing, I wonder if that means they got their first 10 orders in? Anybody hear of anybody buying one?
