Hi all iv just picked up my impreza today and gotta say am loving it... Couple of questions tho.. I was told the standard boost pressure on an imprezza is 0.8 but mines running 1bar with no mods ?? Its a type r v6 v limited is this about right or not??? cheers

Hi congrats.Should be 0.9 as standard as far as I know. That's what my 01 uk turbo shows.

As above it should be 0.9 bar of boost as standard. It's worthwhile getting it checked to be safe.

Being an import it will run more boost than a UK turbo as standard IIRC (UK turbos were 'de-tuned' with a piddly TD04 whereas the imports had all manner of turbos throughout the classic ages). Not really sure what turbo you'll have on a V6 V-Ltd but 1.0bar doesn't sound that far out. I'm sure a more knowledgeable head will confirm the correct boost pressure for your model and year, and if not a specialists (loads on here) will.

P.S. I have a UK turbo with said piddly TD04 (remapped to 1.4 bar though ) before anyone gets upset LOL.

You do well, some whack up the boost without the proper mapping/knowhow and then complain why their engine goes BOOM

Be worth checking the map is ok for UK fuel too as with it being an import fro circa 2000 it's original Japanese map would have been for 100 ron fuel so even V-power or Momentum wouldn't suffice without octane booster (expensive after a while).

Let us know how you get on.
