in my opinion one of the best 4-pot engines are:4AEG,M42..Toyota engine can be mount with T50 gearbox.BMW engine originaly has 1.8l,136-142bhp,10:1 compr.ratio.But with some little extra,it can be stroked to 2.0l,200bhp,12.0:1 compr.ratio.
end it's has not so comlicated EFI System,+ it's from RWD car,so you do not need all this nigthmare for converting FWD TO suit RWD car
