yeah, it's similar in concept to EGR, I remembered when I posted WTF it was. thanks, though.

 

no, not really except theres emissions invlved,

SAI is air injection system that blows fresh air into the exhaust system on cold startups so the catalytic converter gets up to operating temp quicker.


2.4 manifold is well worth it, even without a tune.

Vulcan manifold is a turbo manifold.

 

Another thing to note about the midrange torque loss is that on the now infamous dyno.. even with the 2.4 intake manifold loss the torque was still higher than on a stock car.

 

IMO every 2.2 should get the 2.4 mani. its a great upgrade.

 

EGR recirculate exhaust gases to accomplish the same thing I thought, either way, I'm glad we only have one vacuum hose and only the EVAP system for emissions, these cars cost so many times less to maintain because of the simplicity, but still have a very respectable emissions rating

 

EGR recirculates burned exhaust back into the cylinder so less fresh air can be in the cylinder, less air means a different burn, a different burn means COOLER temps in the cylinder, which reduces oxides of nitrogen production.

SAIR injects fresh air into the exhaust system which reacts with unburned fuel creating a HOTTER exhaust bringing the cat up to temp quicker.

 

*blink blink*

so let me get this straight cause i only have like 300 to spend here. if i get a tune it will be pointless cause i'd have to retune to get the most out of the intake mani. right? so would it make more sense to just get the intake mani then when i get more money get the tune?!

 

the part of the tune that is for the intake mani is a rev limiter raise, this can be done in anticipation of the mod. What I would do is tune it, do the intake manifold. then find a cheap exhaust manifold

 

Sorry to bust in but can I run a 2.4 intake mani without a tune?

 

hello *tap* *tap* *tap* is this thing on? *tap* *tap* *tap* yes, the only difference is the rev limiter is raised to take advantage of the moved power band, but if you run it with your 2.2 TB you will need an adapter and won't take full advantage of it. If you change the manifold and the TB (the way I would do it if I was interested in this mod) you need a tune.

 

there's really nothing wrong with the 5-speed's they are in fact a real transmissions! plus, dropping a 6-speed into a 2.2 would not really accomplish much on it.

 

better cruising MPG and more gear selections to keep RMs in a tighter range, higher top speed, ect

 

i get your point i really do i thought that too but first off the way we're geared 5th i beleive its already a double overdrive. yea its at a higher rpm, but its meant to work that way. If your complaining about 30+mpg highway you already have, you bought the wrong car go get a geo metro. secondly, shorter gears on our cars will basically just mean more shifting and depending on how you can shift may actually lower your performace. Look at the 6-speed swap for an ss, yea its nice if you can do the gearing but from what is seen theres really not much of an advantage to it. people just look down on 5-speeds cause they think there not as good cause theyre a gear short, but few cars even pull in 6th, they reach top speed in 5th.

 

6th is the new overdrive gear. in overdrive your not supposed to really gain.....

 

is the 6 speed conversion a different transmission, or just an add in gear?

 

Its a complete gearset swap for the F35.

If you want a 6spd, buy a Cruze next year. 6speeds are for economy on the street.

 

I don't want a cruze, I want a ion, that's why I have one.

 

Well then your looking at like $7500 minimum to get an F35 with Quaife 6spd kit. Or trying to wedge an F28 or an F40(junk) in there. Its nice to want things 6speed swap in an Ion is gonna be big monies.

 

a good used F35 W/quaife is only like $2K

 

6 speeds are nice, but not worth the investment if u ask me.

think about it this way. instead of having 4 gears divided up between 0-100, your dividing 5 gears between 0-100. so while yes this does sound faster, think about shifts and the possible lost time from those shifts.

now if u could get a 6 speed geared so that 6th ISN'T an overdrive and the gearing makes sense, it would be easier to justify.

after having driven plenty of 6 speed vehicles, and one seven speed(take guesses people), I gotta say it just wouldn't be worth it.

 

it's a BMW M5 or M3 I would imagine, as I doubt you would be driving a Bugatti Veyron. And I would only do this if I found myself needing the F35 for strength, the 6 speed would be an added plus.

 

or a minus when a 5 speed of the same dyno pulls away from you with it's fifth gear :-P

 

what have you driven with 7speed?!

there's a lot. mercedes, bmw, lexus i believe. which one?!

 

Yup and then you need a at least $4500 for the 6speed setup, you need mounts, you need cables, you need a shifter, console trim, axles........Like I said, at least $7500

 

why do I need all that? I have an f23 all I should need is the mounts and axles, and maybe cables, but I believe they bolt right up.
