that would be the ultimate intake conversion then ...

987 air box - $250 used
987 engine cover - $100 used
996 3.4 intake manifold - $250 used
997 plenum - $50 new (you could use the 996 plenum, but one assumes the 997 part is an improvement)
996/997/987 throttle body - $100 used
987 maf housing - $100 jobber

$850.

get a softronic tune that let's you use a 987 maf housing - $700 on sale (or $50 labour at your local indy if a 996 3.4 x51 row pre-variocam+ tune will work).

finally, a $500 performance exhaust (topspeed or 987 S take-off) and a $200 underdrive pulley.

so, potentially 300 hp bolt-on (+50) for $1,600 to $2,250 - worth it?
