how do they measure.......

[MustangChris]

MAFs and TBs?

i bought a used MAF, a used TB, and used injectors. they all (havent checked the injectors) and they LOOK exactly the same as my stock. is this right?? i dont get it...

 

[5.Woahhh]

What size is the after market TB and MAF?

 

[94 DropTop]

the color of the injectors will tell you the size. Just measure it with a ruler. stock MAF is 70mm and stock tb is 55mm i believe

 

[MustangChris]

I measured the back side of the MAFs (the side without the gasket) both are 3.5 inches.

the only visual difference is that my stock one says "Made in Japan"...... lol.

the MAF is supposed to be an 80mm
the TB is supposed to be 75mm

the opening on the front of the TB is 2 and 3/4 inches. and i held it up to my stock on and it lines up exactly.

the injectors are a black housing, with a green o ring on the botton and a blue o ring on the top and a brown clip on the mid section.

 

[BigTang]

the injector top will be the color you are looking for, the area that goes into the fuel rail and the harness clips in will be red or blue or brown or green if they are ford parts. if they are all black and are supposed to be 24's they might be from a camaro and there isn't really a way to tell what they are they could be 19's or 24's.

 

[MustangChris]

they are supposed to be 36#s and has a blue o ring on the top.

 

[BrandoGT]

well (2.75 inches) X (25.4 mm per inch) = 69.85 mm so in theory that TB should be 70mm
and the MAF (3.5 inches) X (25.4 mm per Inch) = 88.9 mm I don't know where that would put you i would say closer to 90 mm rather then 85 mm.

As for the injector listen to what bigtang said. I would search around and find out what 36 lb looks like

 

[MustangChris]

okay, thanks guys.

1 inches = 25.4 millimeters

When you take 2-3/4 you do 2.75x25.4And the answer comes to 69.85mm so 70mm The opening where the Butterfly opens it a polished surface area and its slightly larger then the air horn opening.
When you take the maf at i think it was 3.25 inches and multiply it by 25.4 you get 82.55mm so 80mm

BROWN Is the color of the injectors and there 36# for injectors.The O Ring colors dont matter or the housing just the color ive the top if its a EVI Style but with the style you have the colors are snap rings the go around the injector.
Injector colors:
Orange: 19 lb.
Light Blue/Black: 24 lb.
Red: 30 lb.
Brown: 36 lb.
Light Green: 42 lb.

4.6 Stock is 70mm air horn opening with a 65mm blade so in reality its only a 65mm

 

[MustangChris]

thanks brotha... on my way to figuring all this out. lol.... and learning quiet a bit along the way.

 

[GDawg]

Like Cube said Chris, you should have a 65mm stock throttlebody. I have a 75mm and you can definitely see the difference. (I have my stock one still in my toolbox.)

i mesured it with my older brothers calper last night.... 83.xx mm...... LOL!..... gotta love those previous owners.... lol... threw a few goodies on my car.. lol

My chip is attached to the computer which is located under the passenger side kick panel.

 

[MustangChris]

ill go take a look. because it has stock injectors (orange, 19#) and an 80mm MAF, from what I understand when you put on a MAF, you need a chip or tune. and ... well... .. lol. 80mm is not near stock. lol

80mm is a little over kill for your engine with no blower. Are you sure that is correct?

i agree. but it runs like a champ (slow, mind you. But what do you expect for, what? 230crank horsepower at 6,000 feet?)

its durable, reliable, and strong... doesnt burn oil, dosent misfire, not a single problem. I run my car as rough as every other 20 year old, except my transmission still functions perfectly... and its never given me a problem other than the ball joints. lol.

If they are Ford OEM injectors then 36lbs are dark blue not brown. I know this because I had a 94 thunderbird supercoupe and it had 36lb injectors stock, they were dark blue and so were every other set that I saw. If they are not ford oem then you will probably need to get a number off the injectors since different aftermarket brands have them different colors. OEM injectors are bosch. I wouldn't go throwing that mass air on there until you figure out what its calibrated to. Assuming your ECM is in the same place as my 95 mustang it should be behind the passenger side kicker panel.

ill take a look tonight... is its bizzar... i kinda yelled at 330 cube, but we got everything worked out... i thought he sent me a 60(whatever) MAF, when he said he was sending an 80 (which it is) and it looked exactly like mine on my car... which now happens to be an 80. lol! it runs great, i dono anything about it... lol.

the previous owner for sure put it on there.... it had intake, exhaust, pullies, gears, strut tower, wheels, tires, and (apparently) MAF all when we bought it... maybe there's a chip on it too!
