Well it was actually last week, June 12. For many pinoys and pinays this is an important part of filipino history. That's if you can actually remember it. I had completely forgot about this even though I went to the motherland in '98 to celebrate the 100 anniversary. But a few locals still remember and what better way to celebrate than to shoot some guns.
So I attended a private range sponsored by a filipino practical shooting group. What is practical shooting? In a car guy perspective, it's like autocross. But instead you shoot at targets moving from point to point, instead of trying to avoid the targets aka cones.
With the all AE86 competition coming up this weekend, i thought i had made enough preparations to get ready. Mainly hold off on events so I don't break anything until then. So I had some stuff worked on, like getting the cylinder head ported and rebuilt.
Once everything was up and sort of running the ecu decides to take a crap less than a week before competition. Unfortunately, they won't be able to diagnose the ecu until friday. Now that's cutting it close and between now and then i've gotta start thinking of a back up plan quick to make this event. Just in case the ecu needs to stay in for repairs.
Broken are never fun. There are times that you get them out with a single tool. Other times you'll need a bunch of tools to get them out. The final alternative is to take it over to your local machine shop.
Unfortunately, with all the knowledge and countless tools, it's the last stud that was a pain to remove and fix.
The tap broke inside the hole. Since this is hardened steel, it doesn't drill out very easily. I had to use a Dremel with carbide bits to slowly grind away until I could yank out the pieces.
But mission accomplished.
Casualties: 1 Snap-on drill bit 1 M8x1.25 tap 1 Snap-on carbide bit 3 hours of sweat and cursing.
What annoys me most is the Snap on crap. Alot of money gone in a split second.
It's been over six months since i've been back at the shop to work. But I must keep a promise so i'm back to wire up another car. The car i'm working on is an old Toyota Corona Wagon, with a nice JZ motor. It's been sitting for a couple of years, but finally decided it was time to get it out of the shop.
For an old car its not too bad. I think it was previously owned by a Japanese guy cause the ashtray is actually being used. We all know americans like dumping their cigarette butts out the window and causing fires.
Let the headache begin. It's good to have patience.
Once it's done, it'll be a screamer. Hopefully the rest of the car will hold up.
So I get a call saturday from good friend Brian U. It seems he's got a problem with rats and needs some assistance. To my dismay they decided to attack his beloved JZA80 Toyota Supra. Instead of attacking the AE86 Toyota Corolla. At least they know the where to go, for that high dollar good taste.
They chewed a couple of the wires, so I had to do some emergency surgery. Luckily the little boogers didn't do too much damage.
It also smelled of rats too. It'll need a good pressure washing.
So next time don't go pissin' off Ben or his buddies. This may be the result.
Foodies always have their favorite restaurants. For me, I have my favorite hole in the wall shops. Saturday, I was able to visit both of them. A machine shop in downtown in L.A., and a smog station in Covina. Both are out of my way, but i've entrusted my business to them.
The machine shop, i've been going there for a number of years and had them machine many engines from built 3SGTE to 5AGE. I've always liked their work, compared to other places. I always get recommendations on shops to go to because they work on 'race engines'. Sometimes I think those types of shops work aren't up to snuff unless you're someone who's got a big budget and others look similar to everyone else.
My reg is up soon it was time to visit the smog shop. I known him for a few years when I used to work at a shop that was down the street. He's legit so don't roll by with your cammed and itb'd engines.
Took the stock daily for it's bi-annual test. Yes it did pass with flying colors.
This weekend I was supposed to install the rebuilt cylinder head. Unfortunately the machine shop didnt' get it done in time so my stuff is on hold until then. But the neighbor decided it was time to paint the car. Since I had time to spare, I assisted with paint. Pointing out spots he missed and areas that needed more paint.
But let's start the festivities by quenching the thirst on this warm Memorial weekend.
After a beer and a few cans of spray paint we come up with this. And I have to say it looks hella hawt. For now I will keep it a surprise. You can peep this work of art at the drift social meet/competition and car show, which is happening on June 20th at the balcony.
I'm not sure if i really like or hate this thing. Definitely a very unique mix. Taking a old Hondahatchback and stuffing a Toyota's supercharged 4AGE into the boot, ala Ford Shogun or Renault R5. Though I think it's just the looks of it just turns me off. It'll need a good drop and some gigantic fender flares to make it look cool. After looking cool, the reat of it should be taken care of since there looks to be a couple loose ends that need to be taken care of before it should be considered safe for bashing on the street.
This beast is up on ebay looking for a new owner here.
Porting is something most do it yourselfers rarely tackle. Most seem to think it's a daunting task to take on themselves. While others want a professional to do it, but don't have the $$$ to shell out.
Since I'm already redoing my oil puking cylinder head, it's time I did a little port work. I'm not a pro, but i've experimented enough to take on this project myself. It's what I call a street port, since it'll be nothing close to what a full race port should be. If you want that you should give Hasselgren a call for the ultimate in 4AGE porting jobs. The street port entails the smoothing of the imperfections in the ports so that airflow is not greatly increased, but has more of streamlined flow into the cylinders.
You maybe thinking since i'm turbo i don't really need to do this, just crank up the boost and bam more power. Think of it this way, by adding a wedge in front of a brick like the battle wagon (Volvo 740 wagon) to streamline the airflow, you can increase the top speed and fuel efficiency of the car without upping the power output.
Anyways here's some areas that do it yourselfers can work on.
There's the traditional port match to the intake. Use the stock intake gasket as a template for the cylinder head and intake manifold. I believe certain racing groups like SCCA allow this type of porting to 1 in. from the flange surface. This should be a no brainer on how to do so we'll just move on.
The areas behind the valve seat usually have ridges that should be removed. If you have a cylinder head apart, run your finger around that area, and you'll know what I mean. It's a speed bump for air molecules, bumping into each other as they enter the combustion chamber. Clean up the area by removing the ridges until you can't feel the ridge.
Another area to look into is around the valve stem guide. You can see there's 2 little bumps on either side of the valve guide. Some maybe a bit sqeamish about entering this part of the port, so just leave this area as optional if you're not comfortable.
As you notice the areas I have previously mentioned are now cleaned up resulting in a more efficient flow of air into the cylinder head. I didn't take too much material to alter the port velocity of the cylinder head. Not too bad for a nights work. Now it's off to the machine shop to get the rest of head machined and ready for installation.
Well that's about it, at least for me. Anything beyond that we're taking about changing port velocities and flow rates. A steady hand and eye to is needed to keep the ports equal. A flow bench to make sure that flow rates are consistent between cylinders.
