E30s do not come wif ABS.
u sure u wan to do this? if u really wan to go this route, i suggest u look out for cars which are alredi done up, plenty of E30s wif japanese engines in motor trader. save u all da headaches and da previous owners would hav alredi got da JPJ approval for da car.
trust me, u dun wan to do this, a lot of money involved, headaches n things can go wrong. alredi its costly to transplant a BMW engine into a BMW wat more transplanting a Jap engine into a BMW?
do think twice about it.
my 2 cents
