From my experience, the MHI-18K and the above basically tune out the same.
All less than my power goals. I want more than 450 and less than 550 and not have to run the turbo on full kill to do it. For the track at least.

I would say 500HP would be just fine

Well looky there...there is!!! .... Not sure if that is a problem if it is similar to the BBK full design that was so much fun. Had great transient response which rules for track use........ also

I want to make 450-500 at 24-25psi, without stressing the turbo and blowing a bunch of heat.

The BBX and Dom 2.0 (basically same thing) always advertised lower flow than actual.

I think your higher CR would help in that area not having to over work the boost function...Oh you are considering 2.2L also?

Unfortunately, it's hard to make big power on stock from Evo X stuff.
When I was talking to Aaron about a future upgrade for my friends X, he said they only were able to get ~540whp out of an FP red on a X, at a whopping 38psi.
The tiny exhaust ports on the X head that are good for emmissions aren't so great for power. Add in a restrictive turbine housing and the package doesn't do so great. Especially since the intake ports flow so well. The X really needs to breath better on the exhaust side to make power (T3 setup). It doesn't work quite the same as the 8/9 stock frames.

The 4B11 REALLY wakes up once you go beyond stock frame and you can rev them. I had stock cam 4B11's with PT6262's make 450whp on 91 octane @25psi, which took a Blouch/CBRD stock frame E85, cams and 28-30psi to make.
Then, if you build them and really let them rev with a high flowing turbo, they can make really awesome power:

Cheap cams:

Not sure if I would go with used though. The X using flat tappet cams, improper break in can easily lead to a flat lobe, and a waste of money..
