If it's done right & the budget can expand, nothing is impossible.... I say just shoot for 200hp.... There's alot of other forums like civic-eg.com that have alot of na'd & boosted builds.... The highest amount of hp for a boosted d series that I've seen & perform was I believe 416hp.... But there are other boosted d series with way more power, just saying it what I've seen.... So like I said to go na and want to shoot for 200hp isn't a long shot at all.... It just depends on your budget & what items you choose to run with....
But everyone has their agreements & disagreements about it.... I say run for 200hp just because it would be an insane build & blow alot of Honda owners minds when you could possibly run a low 12 in 1/4 mile pass on a d series build with street tires, maybe lower if you run with drag radials.....
