I am building a e30 i am not great with figures and power i am trying to work out whether the 2.5 engine with a turbo on will give me more power than a m62b35. I have thought long about what to do and then decided i would ask others for opinions and tech spec. I have the 2.5 engine already so would be the case of buying the extra parts or i can buy a complete v8 engine with everything needed for the conversion.
Stuck what to do
