Bros, i was told the 4g93t terbalik has a 9:1 compression which is the same as the evo3..i've heard ppl say that engine with this compression is not suitable to boost more than 1bar unless it has a thicker metal head gasket to lower the compression..so i was wondering is it safe to boost 1.1-1.2bar on a stock 4g93t terbalik(with the correct afr tuning using emanage)?...thanks in advance
