the key advantage of the MIVEC head is that the high speed cam is basically a race cam, and the everyday drivability is still there, I was just throwing that out there, a regular cylinder head is far more economic, though if you want to ever go that route, contact SPD_FRK about getting a 5 speed ECU conversion harness, those harnesses for the 4 cylinders can run an EVO ECU for the engine, then the regular ECU for the instruments in the cabin, that might be able to be adapted for a MIVEC ECU, once again, just throwing out the MIVEC set up out there again
I do like that you want to do this build so everyone else can do it as well, but with this specific route, there not much of a pre existing path, so of course this is not going to be cheap
the easiest off the shelf mods I can reccomend would be a 5 speed swap, EVO ecu (using a Blackheart motors wiring harness), EVO head (+intake manifold and headers that fit), and NA cams
also, there are many, MANY aftermarket Evo intake manifolds on the market that will support bigger TB's, so a quick search will turn them up fast
once again, just my thoughts on the matter
