Whats the general concensis on boost pressure when running a standard head gasket on an R33 GTR.Im looking at my next stage and wondered if i need a head gasket running 1.3 bar...Opinions please..

ive run rb25s at 1.3 bar day in day out and not had a problem mate,,,,,

From what i have been told the standard head gasket will be OK up to 1.2 bar after that you will need to change it

 

[edmy]

is it the boost pressure or is it just the increase of bhp????

We run 1.5-1.6 bar and NOS, made up to 750hp and still with no issues on a stock head gasket. stock head bolts etc, its all in the tuning.....Rob
