hehehehe made ya look!

Peering into my newly removed intake plenum, you would be confronted with this:





Here are those 'golden' intake runners I was talking about:






So I brought her to a performance shop and for 65 bux he did this:





and this and cleaned it up:

 

definetely be interested in what kind of performance gains (accel, mpg, smoother idle) you get when you slap it back on.. keep us posted

 

Damn dude! Looks like he really opened that thing up. What's the texture like? You might want to consider some sand paper to polish 'er up so all that crap won't stick to it as easily again. I can't believe how dirty it was. How'd that thing get up a tree?

 

here is my PCV mod to make changine the PCV valve a million times easier...AND it allows me to add a catch can if I so desire....

Here is the functioning PCV valve that will be out from under the intake plenum



here is the old, drilled out, PCV valve. I broke a drill bit into 8 pieces drilling it out too... Also of note is the size of the hose. 1/2" vinyl by itself wont fit, however if you put 1/4" vinyl first, then put the 1/2" over its a snug fit. Add a hose clamp and done deal!

 

No problem, and will do, I'm hoping for a pleasant surprise...

Indeed he did open it up a lot. The texture is actually quite smooth to the touch. Reminds me of about a 150 grit or so... I might have to attack it with some 300 wet though.... And who knows maybe some 600 if I feel REALLY anal...LOL that pic has it hanging from an old fence post with me taking a pic of it at an angle.

 

Be careful using clear tubing as a vent. The black rubber tubing is made for high temps and oil, the clear isn't as good for that kind of stuff.

Take it from experience.

 

and will that tubing hold up to 20" of vacuum with out sucking closed, how thick is it

 

good points - its pretty thick stuff so I dont think it will suck closed, however the melting side has me worried....

 

Great job so far Bumpin,

Just wondering if the new PCV valve can be positioned horizontally, rather than vertically. I've heard that there may be some gravity assist, rather than just vacuum controlled. I also broke a bit while trying to drill out the innards of my old valve for a mod. I was too anxious to get the whole thing back together again and just installed a new valve and grommet in its original place. BTW, I had that same black build up in the ports like you and the other 3 were pristine.

I ported mine myself but had to pay to get it welded back together when I was done.


Manifold + sawzall


Im currently working my lower manifold while waiting for the head shop to finish making real cyl heads of of my DOA junk. The rest of my motor is being worked over as well. Its being bored 20 over to due to cyl wall taper and the guy also has a sunnon engine balancer so its being fully balanced as well.

 

Nice work. When will you have it back up and running? I would love to hear what performance gains you get.

 

yuck what a dirty hole....geesh makes me wonder how mine is?

 

What you see there is after 258,000 miles from that POS egr system....

 

One thing of note, after reading Ganoid's thread. Measuring the stock TB opening on the plenum, the cross sectional area is actually smaller than the ends of the runners. This slows the air velocity down and opening up the upper portion should help offset that....as to weather or not that's a good thing, I do not know...LOL

BTW my plenum is it's already a good 5mm wider than the back end of the stock TB...

 

so who wants to see some pics of my intake plenum through painting?

 

How's it all going? Please post some pics. This is how I relax between my own 3vze work. Watching your's and a few of the others on here and what they're doing with their engines. Keep it all coming and let us know how it all turns out in the end.

Before after taping...



First layer of paint...



After 2nd coat and drying. Then not paying attention and taking a good bit of paint off of the top of the damn plenum....fortunately you cant see the missing paint in this photo.

 

Another pic slightly out of focus...



And the underside again out of focus courtesy of a slow shutter speed and my unsteady hands...GRRR



I did some quick measureing....it appears thatthe performance shop only took out 0.020" of metal...GRRR BUT the actual opening is a solid 2/10" wider than the TB allowing a larger TB to be used so the air velocity will go up.

Oh well no change in performance save that crap from the EGR.

 

heres the intake side that will go in very soon...

7mge vafm and worthy of note is the 3" (iirc) opening on it's backside....

what makes me nervous about this AFM is that it appears to be hacked....I dont know what's been done to it's insides. However impeadance wise, it checks out....





Stock TB with 3" to 2.75" coupler

 

Now you need to paint the "TOYOTA" embossed letters bright red or metallic silver with chrome flakes for that flashy "bling-bling" when you show off you engine bay. Seriously it looks good. What type of paint did you use??
