How much boost can the stock internals of the engine take? Stock boost is at 8psi right? I read somewhere here about someone running 1BAR on stock internals.. is this safe? Thanks! :smug:

Stock is actually around 0.5 to 0.6 bar. There are several of us running around 0.9 to 1.0 bar quite safely. However, my car has been rolling roaded etc to confirm it's healthy - if you have any doubt your own isn't then play safe and run stock boost.

Dear Oliver,

Don't worry. I'm been running 1.0bar for the past 2 1/2 years.
No prob.

Simply if u want to be safe, get a piggyback ECU..
and a tuner to re-tune your car.

Recommended upgrade: 255L Fuel Pump, Fuel Regulator.
That's all from my 2cents knowledge.

But of course be sure... 1.0 bar won't hold all the rev range..
As higher rpm.. it will slowly fall from 1.0... 0.95... 0.9... 0.85...

+1 This is mostly correct, the block is hardy but it isn't cast iron so just don't use NOS, it's aluminum alloy.
