Project Cold IATS (In take air temps) - want to hear/read any or all thoughts on these - tell me I'm crazy or a genius (first time for everything

)
Options
- Air to Air intercooler
- Pros
- Simple: Few moving parts, which is creates reliability
- Efficiency: Good - not likely to be heat soaked (if done correctly), needs air movement
- Growth potential: Necessary for any hopes of boost increases (precautions and preparations taken/completed, of course)
- Budget friendly: Large market offering, making it easier to keep reasonable
- "cool" or "street cred" factor: Boasts the fact that your car has a turbo
- No waste: Nothing is being burnt or lost
- Cons
- Commitment: Series modification is needed (cutting up the body/fenders)
- Aftermarket finish: Difficult to mimic the Toyota look (if desired)
- Radiator block: Will block and heat soak the air that is needed for radiator (unless top mounted)
- Pressure drop/lag: Longer intake piping (lost boost) and a larger cooler core requires more volume (lost boost)
- Offroad-ability: Dirt/mud/debris could damage and/or clog the cooler
- Water to Air Intercooler
- Pros
- Efficiency: As long as the system is adequate/large enough (Ha!), water cooling supersedes air
- Commitment: Less committing to build or install than Air to Air
- Offroad-ability: Less likely to fail because of mud/dirt/debris
- No waste: Nothing is being burnt or lost
- Pressure drop: Very little to no pressure drop (very short lengths of intake piping & smaller cooler core)
- Growth potential: Necessary for any hopes of boost increases (precautions and preparations taken/completed, of course)
- Cons
- Reliability: Many moving parts or potential for failure
- Aftermarket finish: Difficult to mimic Toyota look (if desired)
- Expense: Many parts/pieces required and all are critical to a well performing kit
- Foot print: Many parts/pieces required - less than ideal in full engine bays
- Methanol/water injection
- Pros
- Reliability: Very few moving parts
- Power gain on stock Ecu: Adding octane to the equation (suck, squeeze, bang, blow). Octane=less pre-detonation = corrected timing = more power
- Aftermarket finish: Much easier to hide and keep the Toyota look
- Commitment: More or less, plug n play. Does not require extensive modifications
- Offroad-ability: Least likely to fail because of mud/dirt/debris
- No pressure drop/boost loss
- Cons
- Waste: (very little) additives are being burnt/lost - will require refills (about equal to every tank of Gasoline)
- Cost: Could be expensive (varying on chosen parts)
- Tuning: Requires tinkering/adjustment to ensure correct ratios
- Ignition/control: Will require a controller of sorts (boost or manifold driven)
With all of that, can you think anything I missed??? Which have or would you chose? Keen to read the thoughts/opinions/choices!
Cheers!!
