Re: Lightweight valve adjuster screws
did you get the right O2 sensor? what about worthless valve stuff that will give you a MP (Mice powah)?

tl;dr
Why wrong sensor? Which exhaust manifold are you using?
Which injectors are you using?
How long has this been a problem?
What fault code did it set? (no code? no problem.)
If it has NOT coded that means the ECM is still controlling fuel delivery within its programmed fuel trim ranges. No problem?
Take a reading of MAP voltage with the engine at fully warmed up idle, all electric loads turned off. What's the voltage reading?

Look at this link- http://www.enginebuildermag.com/2015...rain-on-track/ There actually IS a benefit to a lighter valvetrain. According to this link, you can rev 35-40 RPM higher for every gram you reduce. So 35 more RPM per gram reduced X 18 grams would mean that the engine could rev 630 RPM higher. HP = Torque X RPM / 5252, so more RPM means more power with all else being equal. I’m not going to try to estimate how much power you could gain by doing this because I don’t have any information to go off of, but you would theoretically gain power. Now would you be able to feel the gain? Not likely. Would it be worth the time and money? Again, not likely. But there ARE gains to be had. How much is the question.

I frogot to mention that the valve lash is way out of adjustment. Could doing a valve adjustment help? I heard that the valves being out of adjustment can cause the engine to pull a weaker vacuum, which causes the MAP sensor to report a higher voltage, and therefore the ECU dumps in more fuel. Does that make sense?

the ECU is obviously smarter than you.
our cars VTEC just opens the 4th valve in each cylinder when load is higher or RPM.
3 valves per cylinder works best for lower loads, lower RPM.
You are actually decreasing performance in lower RPM or lower loads by making your finger decide when to turn VTEC on or off.
Thus, ECU is obviously smarter than you that thinks you are gaining MP's (Mice powah) while actually losing torque (which is what is important in lower RPM).
stop mental masturbation and go do what actually need be doing.

then run custom pipe of each to each cylinder head port. u need to make sure all sensor are accounted for, its a project and design..
sometimes comes down to money and time want to spend on it.. thats why people do k20 swaps.
simpler more power.

IIRC, the original had the Mitsubishi logo on it, so I think you're right. Would a Denso for $170 be a good choice? Or should I get an OEM alternator from a junkyard? I don't have money to get an OEM alternator, and I wouldn't waste my money on one if I had it.

Great suggestion, but I'd rather put that money towards a K swap. Besides automatic VTEC, what would be the benefit to getting a VAFC? I know that the light switch is slightly crude, but it is temporary until I do a K swap.

Low mileage used unit for $20? Worth a shot IMO
You have another car with a good alternator in your driveway??? Swap those and see what happens?

...DSM ITBs flow better for N/A vehicles but make little sense boosted because each of those would still be fed by a single 2.25"-3" intake from the turbo system.
...unless you ran four turbos that each went to one port on the ITB, lol.
