ur chasis is for 1.3.u ask jpj to approve ur 1.3 to 1.6,they allow it
cos ur still not exceeding the 25% rule.but if u getting a 1.8,i don't
think so cos ur car is still consider a 1.3 even though ur using 1.6
engine already.for them,chassis is the issues.they don't think that
ur chassis is capable of supporting such powerful engine.
