TermiziYeoh,
My 4G91 turbo kit run with stock internals + 1mm metal gasket... boosted 0.8 bar no problem. =Þ But thats a 4G91 la... coz' 4G91 stock compression not very high... if not mistaken the stock compression ratio is 9.5 only (read it somewhere). No guarantees this setup will work on other engines. =Þ Best is u go for a compression test lar... if possible try to get it down to around 8.5-9 la at least to run a slightly higher boost... otherwise just stick with 0.5 bar.
RAMD TT here there everywhere... and furthermore fridays i'm usually not free to online lerz coz' i'm usually out the whole day (so need someone to update me where's the TT)... i tried going to the TT a couple times... but that few times the fellas never pick up phone... so dulan i went elsewhere. =Þ
What engine u planning to BOT on?
