So I decided that I'm going to keep my S2K and just fix up the turbo kit and put it back in. I went through the manual from Greddy and I'm trying to order the couplers and clamps. Here is my question

I see that the silicon couplers are (1)50φx70mm, (2)60φx70mm, (1)70φx70mm, (1)50φ-60φ reducer and (1)60φ-70φ reducer.

What the hell does that mean????!!!! 50 Phi? What?

I also need to replace pipe 9 and I would like to replace all the camps and get t-clamps. Intercooler too...

 

the symbol you are seeing refers do the diameter of the coupler. if you would like to convert those in to inches all you have to do is divide by 25.4

 

LOL, umm that was pretty obvious, but is it the inner or outer diameter?

And yes 'mm' stands for millimeter, or 'thousanth of a meter'. Every civilised country in the world has been using these units for the last 40 years or so. YMMV.

 

You know what they call a 1/4 pounder with cheese in France?

 

My favorite movie of all time!!!!


Vincent: Yeah baby, you'd dig it the most. But you know what the funniest thing about Europe is?
Jules: What?
Vincent: It's the little differences. I mean, they got the same shit over there that we got here, but it's just – it's just there it's a little different.
Jules: Example?
Vincent: All right. Well, you can walk into a movie theater in Amsterdam and buy a beer. And I don't mean just like in no paper cup, I'm talking about a glass of beer. And in Paris, you can buy a beer at McDonald's. And you know what they call a Quarter Pounder with Cheese in Paris?
Jules: They don't call it a Quarter Pounder with Cheese?
Vincent: Nah, man, they got the metric system, they wouldn't know what the **** a Quarter Pounder is.
Jules: What do they call it?
Vincent: They call it a "Royale with Cheese".
Jules: "Royale with Cheese".
Vincent: That's right.
Jules: What do they call a Big Mac?
Vincent: A Big Mac's a Big Mac, but they call it "Le Big Mac".
Jules: [in mock French accent] "Le Big Mac." [laughs] What do they call a Whopper?
Vincent: I don't know, I didn't go in a Burger King.



Sorry to thread jack, but couldn't help it.

I understand that 70mm means 2.75in roughly in diameter but what is the 50φ part. I'm assuming it's different somehow since it is inventoried as 1, 2, and 1. If it were all the same then why wouldn't they just say (4)70mm couplers? And for the reducers it says 50φ-60φ and 60φ-70φ. What does that mean?

 

I expect the φ refers to inner diameter.

 

If that were the case, why would they tell you the outer diameter?

φ is a number and not a measurement. So this confuses me. But according to wikipedia:
So then 50 units x 70mm?? What? Units of what?
Now it sounds like the 70mm is the length of the coupler and not the diameter... I don't want to buy all the couplers only to find out that they don't fit.

 

I'm sorry, I may be confused but where do they tell you the outer diameter?

I assume 50φ means 50mm inner diameter of the coupling. Or in other words, to fit around a 50mm outer diameter pipe.
