E30 316i is 1596cc 100bhp , 318i is 1796cc 115bhp
E36 320i automatic of course lah slow off the mark, but is it slow on the run especially pushing from 100 to top end, I dont think so unless the car is running poorly. The e30 316i automatic moving off is more or less the same like e36 320i, but with a manual transmission it would be better but dont expect it to be as quick as a errrrr say CIVIC of the mark. As for me, my car is E30 316i automatic and had dump that stuupiiddd engine because of warping head+leaking internal and now i have an M40 1.8. Ever since i own this car in mid 2004, its moving off i say man, bicycle also faster lah ehhehehe. Thought my auto transmission was sluggish but after i put in M40 1.8, different story happen. My old auto transmission had no fault actually and now moving off kapchai also left behind. On the plus side after using the m40 1.8, my aircon when turn on i don't feel any load restraint unlike when using the 1.6, i think this is due to the 1.8's higher torque.
