go wide mouth and welly cooler or oem look with toyosports intercooler aiming for 250-260hp

hey guys im thinking about doing widemouth conversion and installing a welly cooler but im a little torn does it make it alot cooler to have a wide mouth and a welly cooler compared with the standard hole in the front and a toyosports intercooler kit???

my car has an upgrade turbo from a turbo tuning company here in sweden thats suitable for 260hp

a 3" downpipe with 200 cell race cat and 2,5" exhaust after the cat all the way back

and will also get bigger injectors installed soon i have 4 new blue volvo t5 injectors "0280155830" 

and it will get remapped by a guy that makes the tuning programs for a wellknown tuning company here in sweden im aiming for 250-260 real hp

i changed a pic in paint  so you can compare the original look and say what you think i should do oem or go widemouth
