...plan at the time was to go with a cosworth MAP (3bar - 2 absolute) ... 2bar - 3 absolute! Sorry don't mean to sound pedantic! Heard conflicting info if the ecu goes into limp mode over 1.5 bar All (or most) MAP sensors output a voltage from 0-5V no matter what pressure range they can measure. No matter whether you have a 1bar/2bar etc... MAP sensor all the ecu sees is a voltage between 0V and 5V. As long as you know the MAP breakpoints, you can recalculate them for whatever MAP sensor you have.

Very true but there might be a safety routine in the ECU that if it sees 5V's on the map sensor it goes into limp mode.

2bar - 3 absolute! Sorry don't mean to sound pedantic! Your right, sorry wrong way round All (or most) MAP sensors output a voltage from 0-5V no matter what pressure range they can measure. No matter whether you have a 1bar/2bar etc... MAP sensor all the ecu sees is a voltage between 0V and 5V.
As long as you know the MAP breakpoints, you can recalculate them for whatever MAP sensor you have. Agreed, they both have 0-5v outputs but obviously if you are using the same number of breakpoints for a wider scale (range) you lose resolution. I had heard that when the boost exceeds the max voltage for the sensor the ECU goes into a limp or breakdown mode, I believe this was Dink or Vas who told me this but I have never been able to confirm it, however my car did go "a bit strange" after an overboost in excess of 1.5bar. I have run 1.45bar on the dyno where standard injectors were too small for a T04e turbo, but if the option was there I would run 25psi (1.7 bar) as my turbo is still efficent there (50trim) and at 8:1 I think it should be do-able

can the rods take it, headstuds or head gasket for that matter?

From what i have gleaned off the integrale forum, yes. The old EVOCARS chip used to run 1.7bar mid-range but would suggest to swap the head gasket for a start, but people ran it without doing any of that and seemed to have no issues.
