<span style='font-size:30pt;line-height:100%'>1)</span>Considering how much of a pain in the ass changing out the spark plugs on the V6 is, as well as the cost of the plugs (between $500-1600 ~ it seems the dealership charges 280 PER VR4 360cc, and aftermarket only sells them in sets of 4), I was wondering if I can get away with placing a single/double injector(s) at the throttle body in order to supplement the AFR. I could control the pulse width via the emanage (which incidently comes equipped to do exactly this).
I got this idea from RIPPs SDS. It seems that a while back this is how they did it. Though they dropped the idea due to problems with running TOO rich up top. Now their coming back with the same idea (so now you have a meth injection alongside gasoline). I was wondering what are your views on this setup? Is it even possible to achieve equal fuel flow through all cylinders?
<span style='font-size:30pt;line-height:100%'>2)</span>Next question has to do with water injection at the throttle body. I've heard of a few people using water injection in place of intercoolers (at low boost atleast), to control charge temp. Is this a viable short-term solution?
The idea of the Carb/EFI setup came from these threads (the first thread goes into some detail):

What we’ve done….
The stock injectors remain installed and the car is seemingly stock when started. The car idles completely normal and runs “factory” under non boosted situations. When the car sees boost (thanks to new technology in the Black Box) the Black Box does two things. First it activates 1 or 2 supplemental injectors (depending on the application) installed in the 90Degree boost pipe. Almost simultaneously the Black Box pulls back timing according to boost. This allows the vehicle to operate completely stock under normal conditions and run strong under boosted situations. This allows for customers with different Mods to run perfectly because the car will be getting fuel in the exact amount that specific car needs instead of when the “average” car needs it.

I have already purchased a Greddy eManage, along with the ignition harness, injector harness, support tool, etc.. One thing I could do is devise a way to mount 2 of the 360cc injectors from the Stealth in the manifold and control them via the additional injector control on the eManage. This would greatly increase the non-boost driveability, as the stock ECU would not be tricked by a modified MAS signal.
