They start at about $250 for engine only, then they go up from there, it will depend on what else is done to your car,to how much it will cost . I will be looking at paying around$500-$600 for my car when it is finished.(my car is an ET pulsar that has had nearly every part of it modified,eg: body kit, Engine conversion, 280mm twinspot frontbrakes,No door handles + a few other things that will need to be engineered )
