can someone confirm the size of the Greddy turbo kit piping. i know there is 2" and 3" but is the middle size 2.5" or 2.25"? i got some 2.5" couplers but they seem a little too big.

can someone confirm that they are 2.25"?

They have a parts list.

 

wtf is that circle crossed out symbol?

 

damn metric to US measurements. should just all be metric.

 

They are in MM's.

So if you see the pipe that is in question - and go to that install step they tell you the PN for the coupler to use.... and viola you have your coupler size.

 

1MM divided by 25=inches.

 

listen to tubingchamp - stands to reason that he would know .... LOL

although on this occassion - not so much

1" = 25.4mm

 

^^

We just use it as a base here at work :D...

For this application, 1in=25mm should be accurate enough... .4 isn't so much when we're talking 50-75mm.

If a company is selling 75mm piping, they're not going to advertise it as 2.95", it'll be 3".

 

that's what they said at Chernobyl LOL

 

looks like 50,60,and 80mm. so 2,2.25, and 3". thanks for the help guys. i don't know why i thought it was 2.5".

 

on my first pipe work I used 2.5" as I couldn't easily get 2.25". it is a tight fit but 2.5"can be used.

 

Lol, I just noticed what I did.. Good call Brett

Work + forum - thinking = fail.

 

just be thankfull i didn't quote you and put it in my sig. - heh

 

the circle with the line through it is the symbol for diameter
