Did i miss anything?

[Sleepy_Steve]

Ok, so i have my ka24de in an s14 - and it needs a bit (a lot) of work. But while doing that work i wana have a bit of fun.

Please let me know of anything i may have missed in the NA realm of things... as well as anything i mentioned that may not be worth the effort. -- also point out anything that will fail me in emisions. Thanks.

Fun i have thought up is as follows:

1) advance timing 5deg, run 93 octaine... w00t there was a thread recently that explained how that works. - this seems like it might even be emissions legal - is that true?2) cams - not sure where to get, or what to get... have heard a 95 altima cam will work, but know little more than that3) Exaust - is it worth the cost for a full system? is going from 2.0'' to 2.5'' realy worth it? and if so, what will i notice improvment in?

There is some real work too... passing inspection and then emisions are things i hope dont cost me too much money.

Oh, and one last engine related thing. The engine runs a bit rough - as if there is knocking or not hitting propperly - could this be a valve issue?... problem is im new to cars, and cant tell whats up with it.

intake (injen ins carb ok)exhaust, go custom, keep your cats (both fake and real)Cams, go with 91 240sx, may hurt emission levels thoughSince you want to pass visual inspection, no header for you, unless, you can "hide" one under the stock heatshield. Doable but depends on the inspector eye.

Ok, i get most of that.

What do you mean by may hurt emmisions levels? As in will make it more dirty? Or like will make it fail?

The engine is running roughly?

Is it running differently from when you picked it up, or did that seem to be overly rough?

The idle seemed fairly smooth to me, no different from the other S14 I had before.

Its running the same as when i picked it up. There is some degree of sound that dosent seem to belong... But it also seems as its just a louder engine in general than im used to. My accord is quiet as all hell, and i never heard anything but exaust pipes in my old truck with a 5.9L V8

People have said valves (might be a worn spring or some such), timing chain, and even cat (im fairly sure its not the cat). Most likley the rattleing sound is from a loose heat sheild right in front of the cat.

There does seem to be a clicking sound from the front of the engine, but a mechanic friend of mine said it would be much more noticeable if there were an issue.

I might be able to help clear some of this up.

The rattling most definitely is the heat shield, I actually have pictures of the part you need to remove (I took it off my other S14), so email me and I'll send that to you. There are a couple of similar things down there.

As for the clicking, that (according to my mechanic who sees a LOT of KA's) is just the injectors, and it's perfectly normal. My other S14 did it too, and that car never acted up in 2 years.

In regards to the engine being louder than your Accord, I'm not at all surprised. KA24's are somewhat loud, "rough" engines, they don't rev particularly smoothly compared to, for instance, a silky Honda V6. They also have a very throaty tone for a 4-cylinder, even through the stock intake hardware. I'm not necessarily saying that the engine in that car is perfect, as I obviously haven't torn into it myself to know for certain, but I will say that I didn't notice anything out of the ordinary in regards to the idle or power delivery (save the sticky throttle cable). It seemed just like the 90k mile engine in my 1998 in all respects. I'd be more worried about the hard-shifting transmission, if it were me, but you're swapping anyway so you likely don't care.

I'd do a tune-up, some injector cleaner, etc... With that kind of mileage, I'd be hesitant to seafoam it. I'm not seafoaming my 130k mile S13 for fear of opening up leaks.
