b)The normal service is about RM 200-300.
d)Normal conversions on the e36 are rb series and jz series(skyline/cefiro,supra).

IMO, the 1.8 version of this car is quite underpowered. Drove the 318, 323 and 328 and a 2jz version of the e36....1.8 felt really underpowered. got for a 2.3 at least or a 2.0 at the very least.
