Quick questions

[slammed 66]

Ok, im looking for an s12 at the moment bu i have a few questions.

What sort of mileage is acceptable for modifying the engine? id like one with less than 100k and would plan on:

larger fuel pump
larger injectors
1.5 bar boost maybe
single box 3 inch exhaust
renault megane 225 intercooler (got one kicking about)
hks filter (one of theese lying around too)
adjustable fpr

Does this sound reasonable?
Could a 100k motor take it?
What sort of power would you guess this would make?
Do theese suffer from big end failure like DETs? and what are they like for bore wear at this sort of mileage?

i know the questions are a little dumb but humor me please as it needs to be rapid and reliable as my daily smoker.

Thanks guys
