And in conclusion, the "mechanic" that told him the CEL means nothing and should just be covered up with tape, is a MORON.

The maf is not only a maf, it is a tmaf sensor actually. Timing and fuel delivery are adjusted by temperature so the injector pulsewidth will differ with different temperatures.

Now there are better intakes you can add but it will have to incorporate two things: A way to add cold air (I.E. scoop, fender inlets) and some type of a RAM air system.

P.S. adding a catback exhaust or complete exhaust will help also...
I've covered this many many times, the head doesn't breathe well enough to gain from this.

That's a good start but I like big cams more. Don't forget with bigger cams you want bigger springs because the springs have less time to close the valves.

JP7, what is your view on bigger valves, ever mess with the 2.3 head for turbocharging?

Getting off topic here, but the 2.3's I work with are all 4G63's

I was just easing his mind because my explanation could be construed as colder air = more fuel

I said COMPLETE EXHAUST....I think that includes headers. Cat back exhaust is from the Cat bat, not including the Cat. So no it is not the entire exhaust.

We are talking about the intake, not forced induction, not turbo charging, not new cams so my statement is justified.

Check my second statement.

Next time realize this site is meant to help.

Slow your role Vincent. Jp is highly knowledgable about all types of motors and their basic principles. The guy writes his own tunes, I think he knows what he's talking about here. Unless you know the guy personally, back off the attacks. He's trying to explain a principle to the kid.

You meant head-back exhaust, and I said the engine head.

Jp7, I have no doubt you know more than I do about these matters. Just keep in mind we're throwing our 2 cents in to help based on what we have done or seen. I agree with you about the heads after you pointed it out. The original post was about the intake and that is what I tried to help with. Thanks for your input it added to my knowledge, I just didn't appretiate getting attacked for my 2 cents

Dam guy, you got me good, lol.
I guess i'm curious on your take of big valves and if they are worth it. I read so much, and get so many contradicting results of big valve installs. Some swear by it, some say it isn't necessary. But my science background said big valves give me more air to the cylinder, and thus more power.
Tell me your views, please.

Okay..

larger valves can help performance and if done right, volumetric efficiency... which helps everything. HP and mileage can both gain from this modification.. When you do valves you also want the cam(s) to go with them, and you will need valvesprings that are strong and won't let them float. The only thing bad about big valves and cam(s) is the idle and vacuum loss you get. I have a fully built HKS head and before I tuned my electronically controlled intake timing I was getting 7.5 inches of vacuum at idle. Now I'm getting 10.5. You do lose some low end torque usually but there is a big jump in midrange and the top shelf is much better. I usually tell customers that too big of cams will slow spool down low but the top end makes up for it. It does make it less fun to drive at low rpms (Stall alot if you don't have a sensitive left foot) I get comments all the time "your car dosen't sound so good you should have that looked at) because it sounds like a lopey harley motorcycle at red lights, not to mention the smell. Even with everything else the same, intake manifold, larger valves make it easier for the engine to breathe. That would require less throttle opening at highway speeds or it can take in more air/fuel mixture at wide open throttle. Bigger valves need a machinist to open up the seats, but more is needed. If that was all you did and left the throat (the area between the bowl and the valve) the same, you'd create turbulence and possibly reduce the overall flow as there is now a larger obstruction in the airflow's path. To realize any advantage with larger valves this area must be opened up. I started with the stock head and had 264 degree cams, when I built my HKS engine I went with the upgraded top end and 272 cams. I think this summer I'll go with 280 cams (since now I've got a bigger turbo that won't spool down low) and try and get 700whp with full power pretty much from 5000-9000.

Well, all of this is very complicated to do, and if i was to let some one do this mods that are described, i would need a trust worthy mechanic. What i really wana do is squeeze a few more power from my 2.3 but i understand that its a 2.3. There would not be significant changes in power if i dont mod the cam, valve spring etc. But good thing about a small engine is thAt of gas mileage. Thanks for every bodies help, all the inputs and advices was a help.

Iam going to replace the. Cylinder head seal, i tjink, cause im seeing oil in the spark plug hole. While that is open what would be suggested should be done in terms of mods? How much will it cost me to get a bigger cam, and gain a little bit of torque. I hear u can change the setting of the differiential to get more torque.

You have 2 cams, (1 intake/1 exhaust)

DOHC is Dual overhead Cam.

I think Cosworth makes cams for the 2.3, I think these are intended for the focus though. You will need a tune after cams. I would probably just get it tuned with the stock hardware and thats it.
