Hi i may be coming into a little money soon and want to increse the power of my car.
short of buying a new car, (becuse i do like mine), would it be better just to buy a new engine instead of supercharging or turbo charging.
Vac motorsprots sell a fully turbochared 6 cylinder engine for £5500, at current exchange rate and simpson racing in the uk have M3 engines from as little as £3000 they say. When some supercharger kits ive seen can be £4000 to get anything near that power out of an 323, would i be better just replacing the engine.
or another option a second hand salvaged m3 engine, then i would have to be carefull of the condidtion of it, but proces are looking around the region of £2500
Or after costs of new ecu, gearbox wiring ect would the price rise dramatically.
