ok so i have a 91 318is with the 1.8l 4cyl m42 motor in it, i also have a m20b25 motor and trans that i bought. my goals for the car are around 300hp when its all said and done. this said i have read both m20's and m42's can achieve this hp range (if i was turboing a m20 i would do a Frankenstein with build with 2.7 lower and 'i' head). so with that in mind that I have both engine options, its really just which one should i invest the money into?
considering:
-money needed to achieve desired result
-power to weight ratio
-reliability (as it will be on the street with occasional canyon running and track days)
-etc.
any opinions would greatly help!
