Perfect size FMIC for a RS13 standard front bumper.

[200sxs13]

Hey guys newbie here, had a look through the forums using search for this topic but couldn't win lol

I've got a 1992 200sx RS13 with a CA18DET, standard bodykit all around. I'm currently bringing it up to 300 bhp +/- & all I have left to do
is fit a FMIC. All the FMIC kits out atm require cutting of the of the standard front bumper and crash support bar to fit the core.
Does anyone know of a good size FMIC that would fit well without any cutting of the front bumper and support bar? ie (500mm x 150mm x 65mm)
I would measure it up myself but I'm currently on holiday 3 hours (flight) from my car. My current exhaust pipe measures @ 2 inchecs all the way through from the turbo (GT28) to a free flow muffler at the end. So I'm guessing a 2 or 2.5" inlet/outlet.
Any help or direction would be much appreciated & if all goes well I'll post up some pictures.
If any more info is needed on my half, let us know please & i'll get back to you. Cheers, Also open to any advice no offence taken.
