i wouldnt go past 11-12 psi on stock block with a turbo.
and those numbers arnt that gr8. you could hit 450-500 whp at 16-17 psi on a full race kit with a 3mm hg with the gt35r

yeah, I wouldnt want to run more than 11~12 psi on stock block + hg.
nonetheless, I still want to go with InlinePro's new race kit with smaller fmic and turbo to make about 450whp.

Definitely!
Don't forget if you want some more power you can always use meth.
Got any E85 stations in Dallas?

There are alot of factors that would factor in how much PSI you "can" run
50/50 meth - water injection is the recommended blend for pump gas applications.
the water cools down the charge, the meth acts as an octane booster and allow you to "replace" fuel, run more advanced timing and higher boost.
A competent tuner will know how much fuel to subtract from your map, how much timing to advance and how much boost to run.
Remember... your alcohol injection system should never fail when you are on boost and load or a detonation event may occur and that's not good.

Here's a "sort of' FAQ I ran into while googling... I saved it to a text file.
1. Maximum Torque occurs at a 13.2:1 Air Fuel Ratio.
2. Transitional Fueling and Maximum Boost Air Fuel Ratios are about 12.5:1.
3. Water Injection is most efficient with a 50/50 water alcohol (or methanol) mixture.
4. Methanol, as an additive, is not a practical choice as it is prone to pre-ignition in higher than 50/50 percentages, is not safe to handle, and is not readily available. It's a good choice, but not necessarily the most practical one when you need some in a hurry. Methanol is usually found where racing fuels are sold.
5. Denatured (ethanol) alcohol, typically 95% pure, is available in paint, hardware, and Home Depot type stores in gallon containers for about $10.00. Expensive but available everywhere. Isopropyl alcohol can be used but it is often 30% or more water by content.
6. Water Injection allows ignition timing to be more aggressive or closer to stock. In other words boost does not automatically mean retard your timing.
7. Excessive amounts of ignition retard will cause a loss of power and overheating.
8. Water to Fuel ratios should be based on weight and not volume.
9 . Water weighs 8.33 lb per gallon.
10. Alcohol weighs 6.63 lb per gallon.
11. Air weighs .080645 lb per cubic foot. It takes about 150 cubic feet of air per 100 horsepower. It takes about 12 lb of air per 100 horsepower.
12. Water or Water / Alcohol to Fuel Ratios are between 12.5% to 25%. This means Air to Fluid Ratios are between 11.1:1 and 10.0:1 with water injection.
13. Maximum water delivery should be in higher load low to mid rpm ranges tapering somewhat at peak rpms where load is less.
14. Atomization of the water mixture is directly related to it effectiveness. Finer droplets cool the inlet charge better and with less mass they navigate the inlet plenum easier for more equal water distribution.
