I am planning to get a E36 soon, and saw a 325i with OBD I (95) M3 engine swap listed for sale. Before jumping in before knowing, is there anything else that diffs M3 from 325i besides the following?
OBD I S50 vs OBD I M50 engine
stiffer bilstein suspension
M steering wheel, e-brake handle, shift knob, seats
M bumper, spoiler, side skirt
For example, will the use of 325i tranny/clutch will cause any impact on the S50 motor? If other components like fuel pump are different? Also, is the chassis being stiffen for the M3? Bigger sway bar, etc?
And would such M3/325i 'hybrid' has any issue on passing smog check since the car is California registered? Do you experts see any potential issue down the road with such setup?
Please advise... thanks in advance!
