your skepticism is understandable . 300 may be a bit high . whats the average cost of a b swap? is 3 to 4 thou close? that a whole lot of head work and bolt-ons and even a built bottom end for the d, hell maybe a chip. and i dont think its too far a stretch to say you could use an agreed budget for a b swap and wisely build an allmotor d that could beat a stock b motor. just maybe not a type r. but you know what im saying. you would only need to make about 50 to 80 hp increase depending on the d motor. i think he should minime
