there are few things u got to knw when modding a machine
there is no such thing as less petrol and more power
both goes up together
there is no cheap mods that will give u heaps of power , its nonsense
u must decide whether you want a new engine or u wish to mod the current one
modding is a bigger gamble than changing engine
because it will not promise the power u expect
if u want to mod the 4g92 engine , i would suggest
- turbo bolt up kit + tuning
- nitus + tuning
if u want small unnoticeable mod
- air filter
- exhaust
mod that dont work are such as
- microcompressor
- twin intake
- surbo
if u want an engine which will fit into the budget , i suggest
4g91 halfcut + use your block
4g92 mivec
vr4
but wht i dont want u to regret is , u mod ur standard engine
and totally finish 10k+ and the performance barely compared to a halfcut engine which is just 4k worth
