Vtcs

[BlkZoomZoom]

Just curious if anybody with the 2.3l has removed the VTCS butterflies in the intake manifold. I was reading up on the 2.3l motor today and found that it had them. They are not screwed in like the Fs but I do believe they are removable. The intake manifold is kindove a pain to remove but can be done without removing much else. The hardest part would be is to trick the pcm into thinking they are working sense it is acutally monitioring the system unlike the Fs series. However I already came up with a couple of ideas.

So how many people have done it?

You wish your Mazda 3 trapped 105. Maybe with HiBoosts kit, but even I am not crazy enough to call that stock.

ill take a pic of engine bay, my car definately stock man.

[BlkZoomZoom]

I drive Mazda3's, 6's, 5's, rx-8's, etc. etc. everyday. Unless you did some turboing or supercharging you will not get close to 13.'s.

=)....i think i would make a wager on that...ps can you get stock blocks for the protege cheap? with pistons and rods in them i mean. i might throw a stock one in for now cuz i just bought some fuel mods i want to put in the p5 until i can afford to build a motor.

Put up or shut up. lol

I think there are some posts missing...

[BlkZoomZoom]

Yeah. I think he's trying to make me look retarded and talking to myself. lol

The first post still stands. I am very intrested in seeing how far people have explored the 2.3l.

[mp5jeff]

nah i deleted them for a reason im sure u guys can think why,

[mp5jeff]

the protege spark plugs fit the 2.3 motor...

[BlkZoomZoom]

Are you drunk?

[mp5jeff]

no...dude, just trust me, i wasn't lying in my posts before....but the protege spark plugs do fit =), guess why i was getting new spark plugs, and bigger gap....

[BlkZoomZoom]

Running a different ignition system? If this is the case, how do you think you can get much better than coil on plug?

Also I hope you are still running iridium plugs....

[mp5jeff]

i did not touch the coil on plug =) im not stupid...just changed the plugs, but why would i want a bigger gapped plug?

[BlkZoomZoom]

You lost some compression?

[tsunami]

wtf are you guys talking about? thought this was about the vtcs... ????

[BlkZoomZoom]

Mp5jeff is drunk and I am rolling with it.

I still would like to know why you would increase the gap... The factory plugs have a pretty good size gap as it is.

[mp5jeff]

blk, you aren't getting what im trying to get at about the plugs, but im not going to just say it, specially on this board for specific reasons....i'm sober as can be trust me.

[Mike R]

Do the focus 2.3's have it also?

[BlkZoomZoom]

Do the focus 2.3's have it also?

I'm not positive but I imagine so... As long as they are fairly new (00-01 and above) and also have the plastic intake manifold.

[mp5jeff]

ahh the plastic IM, lovely thing =)....

i've had VTCS removed for about 5 months now. i actually just tried to swap it with someones stock one so Juan could do more accurate tuning for the 6's kit. but for some reason my car doesn't like the stock one anymore?? won't idle at all with it in place?? I'm swapping mine back on Sat morning hoping she'll like that better.

As far as removing the IM, i've done it a good 10 times now and it only took me 11 minutes to remove it this morning (though i think i have more room in the 6 than the 3 has?). doing all the tweaking took about an hour, mostly just trying to figure out what to do. and a bit more time to seal things up and let the stuff dry.

with it removed, especially in cold weather, cold starts are a bit scary. very irratic breathing until it warms up. feels really good above 4500 though, it's only a small improvement, but hey, it was pretty much free.
