what boost are you planning to run / is the engine setup to take?

It is unusual to exceed the standard map sensor (circ 1.7bar) unless big setup etc

not sure what boost im planning to run yet but ive got an rcm450 with all supporting mods? any idea what sort of power i should make on a 2ltr?

The std sensor is good for 1.8 bar, you don't really need more if you have a std engine as thats more than enough. if you have or are planning a big build then even the 3 bar sensor is not really not enough, I would then look at a four bar. BTW the specs are always minus one bar and plus whatever is left, so a 3 bar sensor is capable of linearly reading plus 2 bar.
The oem sensor up to and including MY04 can read plus 1.8 bar, new age sensors after that will read a bit more.

So as Simon mentions what are you trying to do with what spec engine?

cheers

3bar maxes at 2.25bar or the 3bars I use anyway

So unless wanting to run more than 2.15bar a 3bar is fine.
