After reading about peoples issues with high flow cone filters, I've been looking into closed filter options. The K&N Apollo seems like a nice one, allthough my Mambatek GTX2863RS har a 3" intake, so the Apollo 70mm will be a bit smaller. Any experience or views on this filter setup?

"Colourful" meaning a bit of a scumbag He's not on here any more because he got banned! The choice of filter doesn't really matter, as long as it's not ridiculously too small or anything. I've found that cheap Ebay filters flow just as much air and filter just as well (sometimes better) as the expensive brand names. However, the only thing that lets them down is the cheap still mesh they use; eventually it rusts out and clogs the filter. I personally use a K&N filter on my 440 bhp 16VT, purely because it was the right size to fit in the engine bay and has a non-rusting stainless steel mesh.

I too read about the original filter box being a good choice. However, I just bought an aftermarket turbo with a 3" inlet, so I'm going for a solution with 3" sip and aftermarket high flow filter. My only issue with this is that some people on this forum are talking about loss of torque in low revs. That's why I'm looking into the K&N Apollo, which is a closed system (a cone filter inside a box, connected to a cold air duct). Thinking this could be the best of both solutions? The engine is a Lancia Kappa lump with the Kappa inlet manifold, Venolia forged 85mm pistons and a tubular exhaust manifold. It's still in bits, undergoing some work at an engine workshop, so it's a while until I'll be able to test it.

That sounds logical. The aim is 300bhp+, but keeping it below 350bhp due to stock conrods. Maybe 2,5" tubing from turbo to throttle body?

Hopefully some of the 16vt veterans will be along shortly to add their knowledge to this subject. That'll be me! for my 400-odd bhp Coupe I don't even run particularly big tubing after the turbo; IIRC I run 60mm tube just after the intercooler and then the last part of the run, around the engine bay is the standard Coupe tubing - all the way to the throttle body. Also, don't go unnecessarily big with the intercooler. As an example, the intercoolers you see on Ebay described as "Medium intercooler" adequate for up to 300 bhp in terms of pressure drop and efficiency. If you can, always try to use an intercooler that's big enough for the job, as opposed to the biggest one that you can fit. I have a fairly big Evo 3 intercooler, but the other supporting mods (and my tuning skillz!) largely make up for the lag caused by the big intercooler.

Now, there's a thought... I always thought bigger is better due to higher flow capacity, but didn't consider more lag due to bigger volume and pressure drop... So: smaller tubing and smaller intercooler gives more torque faster? Cheaper setup, i guess...
