but since they cant do anything with the r33 ecu you will have to get a z32 or r32 ecu and do some wiring or internal mods to make them work, z32 would be the best option as it allows you to keep the vct, or for just over a grand (1100-1200) you could find a power fc if you hunt around.
if you only want 220rwkw then get a jusp jap return flow intercooler, i would also get rid of the pod and put the factory air box back on (good for 250rwkw so no need for a pod) which will keep you legal, there is also no need for the aftermarket bov either, the factory one will cope fine!
BUT the first thing to get is a 3" cat, for that power an xforce from justjap will also do fine
The other things you will need around 220rwkw is injectors, fuel pump and a z32 afm.
After all of that go to this HYPERGEAR thread and hook your self up with a highflow, i would personally shoot for around 250rwkw to take advantage of all the money you have spent on the supporting mods.
