I'm kind of planning a coup-de-ton on my 2.3L Duratec
Since there is only a few hp that separates a Duratec from the Vulcan I wanted to not bridge the gap... but surpass the V6.
I'm not one to name drop so I'll just leave the brands out. I have a race buddy who modded the crap out of a 350Z a few years ago and ran circles around vettes with a few exceptions of drivers that really knew what they were doing. He is going to give me a hand and be a go-to guy for me if/when I get in trouble or have a question on part selection. I'm posting this to get some feedback from the online community and hear from people who might have done this already.
I figure might as well start somewhere so lets just move the choke point down the line.
1st - intake, get a stock intake from junkyard and cut the box lid back to just enough before MAF sensor to allow a cone to attach, then run box topless but retain bottom to protect from splash up and keep -some- heat out. Basically, it will draw fresh air as normal but have access to much more volume when the engine calls for it. (I'd expect 3-4hp since I'm already using K&N filter)
2nd - exhaust headers, self explanatory. remove sharp angles less restrictive. maybe 10-12hp
3rd - cat back exhaust; I work with the wife of a guy who has ran the most respected muffler shop in my city since 1964 when he opened the place. I sat down with him and talked about my Ranger. The short of the long is this: stock cat's are that restrictive, but there is an un-necessary bend and the exhaust goes from 2.5" to 1-3/4" shortly after 2nd cat... so; cut before bend, weld straight 2.5" to a flowmaster, then side ditch in front of passenger wheel. Maybe 5hp
4th - now that the engine can breath; increase fuel availability for those on demand moments... high flow injectors. The increase depends largely on how much higher they are over stock and frankly I have no idea exactly what to expect.
I'm looking at 18-21hp increase NOT including the injectors. I think that's a pretty conservative estimate since the muffler shop told me 10hp (I disagree) and I've read on other forums that 15hp with exhaust headers is common.
comments?
