swap your motor! you'll never see 200 whp out of d series with a realistic budget

 

The H22 will land you at your 200hp mark, but like reaper said it will cost around 3k. If I were you I would go the turbo route. I think it would be much more fun to turbo the d series you have and it also allows for bigger gains down the road. GL with your build, and yes your car needs to go lower!!! lol
