c900 IC options - comparisons?

OK, this is not about IC efficiency (I've got a Trent Saab IC fan, and water injection to compensate for that) but overall intake restriction/pressure drop. I am willing to go as far with it as to get them to an acceptable level for ~280 hp @ 6.5K rpm, but not any further - as I've got charge air temps under control already I don't need big-a** intercooler, I'd rather change as little as I can get away with.
So, knowing that Kevin K measured a considerable amount of pressure drop with the c900 86- (plastic tank) IC and cast iron pipes (1.4 psi @ 150 hp IIRC), what would be the difference with:
* '86-'88 c900 IC plus 89- thinwall alloy pipes (current set up)
* '89- c900 IC (#75 99 418, less but wider rows) plus '89 on pipes
* FMIC using '91- 9000 IC (lots of bends in intake paths to get under transverse beam and up to TB and turbo outlet)
* FMIC using 9-5 IC (anyone tried that? At least intake and outlet fire straight rearwards on this one)
* FMIC using 9-3 Viggen IC
* any other ideas?
TIA,
Eric
