honestly, if you dont have a honda and are planning on buying one, try to get a 5.0 mustang from the 80's instead, they get 26mpg highway and 20mpg city and it is very easy and cheap to get them up to over 400hp. but if you already have that honda, everyone goes for the b18 or b16 from type r's from japan. in my opinion get the k24 vtec engine from the honda cr-v. its a pretty fast and powerful engine.

Hey man,This question is subjective-it depends on who you ask.Go to www.vtec.net its a site called Temple of VTEC and it has forums to visit where you can see how many have answered this very question.The "best" one to tune depends on what you define as "best". The cheapest, the rarest, the most expensive, the newest?A lot of people right now are putting a 2.0 liter 200 hp engine from the Acura RSX-S into 7th Generation (2000-2005) civics and getting good results.If you can find a Civic Si engine from a 2006-2007 model (I think they came out in 2006-whichever is the newest body style)-that engine puts out a good amount of hp for Honda.A LOT of people have beefed up the B18A, B18C, and other 1.8 liter motors from Integras from GSR, to Type R etc.Some folks have also done work with the B16 motors.The H22's from the Honda Prelude Si has also been done a lot. What I've heard frequently is that it all depends on how much money you want to spend. If you have enough money-then any swap is possible-that's what is said a lot in the Honda community.Also depending on what generation your car is there's probably a web forum for that generation.Mine is 7th generation its a 2003. The newest is the 8th gen. www.civicforums.com is a place to start to get specific about what engines go in your particular car and what it costs.Good luck. have fun. Race legal and stay alive.PeaceDwight

i would go with a k20, on the new si's i have a 98EK hatch with a k20z1 from a 05 RSX type s and hondata k pro, the vtec engages 2x once at 3k rpm and then an 5500k, i spank cars left and right, just as is runs high 12's and its pretty much stock, so now that the Civic 2007 comes with LSD should be better, and besides new parts are easier to come by for the k20. i knotice that Skunk2 cams for b16 b18 and k series are the same price, so prettymuch its affordable either way, but since k series is the new era for DOHC VTEC engines thats what i will do, even is you purchase the sedan they look legit!!!!!!
