The FWD motors are very similar to the RWD setups that are commonly put into 240SXs. Only difference is it's FWD, and it used a distributor. Internally the engines are pretty much identical.
Idle problems and richness could be a bunch of things. Are you running atmospheric BOV? How are your plugs and O2 sensor? Are you getting any check engine lights? Is your MAF connected or working properly? IACV?
