So i am going with a meth kit
If you plan on using 100% meth you better be using all steel braided lines. Meth is highly flammable and burns with an invisible flame. Your car will burn to the ground without you even knowing if a plastic line melts.
I have an AIS kit and using 70/30 meth/water mix.

One injector before the Novi

Two injectors before the throttle body

It all depends on what your going for. If you want to drop chamber temps and allow more timing then do a water mix. If you are just going for detonation resistance with higher octane then run straight meth. But remember that staright meth will cost alot more then a mix.
Lots of people run 100% on NA cars, just the meth burn itself will cool temps, esp. on a FI car. There is no reason to a mix on a N/A car, meth isn't pressurized like n20 and the temps arn't high enough to see any real benefit from cooling, the mix makes operation cheaper, esp. for FI users who see boost frequently, but again imo meth is a back up or enhancement to a charge cooling system on a FI car.
Anything that adds octane and reduces temps is a good thing, the more potent the mix the more octane your going to get. The 50/50 in the mix is more geared towards having a coolant (other than water) so that it wont cause rust. Imo (just my opinion) I am nervous about a mix (esp 50/50) being used on a stock motor, In your case sense your trying to use it as the primary charge cooler I would super duper hesitant to run a mix like that full time/ all the time.
