Quick, whats the diameter of the throttle body?
 

I want to order my IC stuff and I forgot what diameter elbow I need for the throttle body.

2.5"

Are you sure?

I coulda sworn it was larger, I was planning on using a 2.5 inch pipe I just dont remember if I needed a 2.5 inch to 2.75 or 2.5 to 3.

I know the MAF housing is larger then 2.5.

I am pretty sure...I have a 2.5" ID coupler there now

its a little smaller than 2.5" IIRC, but a 2.5" couple works best.

wasn't it like 53mm or something like that...OD is very close to 2.5"

:) I have a 2.5 90 degree coupler and it fits just perfect, this is for an NB though so I am not sure if the OD is different.

Sold. Thanks guys.

Just ordered tube and bends from racing solutions for my IC piping. I wish they had thinner stuff, and I wish even more I could buy it locally, but everywhere I go is rape price wise.

Move south of the Mason-Dixon line :rofl:

If only everything was so simple.

Sorry to threadjack Sam but I'm also facing some issues with the coupler installed on my car (it gets loose pretty easily and I face a leak). I was told at the shop that I needed to get an intake pipe reducer from 2.5" to 2.25".

Is everyone positively sure that the NA throttle body is 2.5"?

Thanks and, once again, sorry to threadjack Sam! :bowdown:

omg, your shop sucks dude.

On the 1.6, it is not exactly 2.5", however a 2.5" silicone coupler is a nearly perfect fit.

Can't say about the 1.8 cars...

No shit and the worst thing is that I've got no option :mad:

Braineack could it be that my IC piping is 2.75"? I bought a used S5 Begi so if anyone has one I'd appreciate some confirmation.

Ill go measure mine today and post a pic.

I'm scared of both the measurement and the pic! :)

I don't think you have an S5 installed.

Thanks anyways Sam.

1.8L is also 2.5" OD IIRC. I have 2.25" pipes on the cold side and had to use a 2.25-2.5" transition for the TB.

I have the 1.8 NA, and I have a 2.5" coupler there...only thing that sucks is that the other end of the intake piping is not connected to a turbo or intercooler
N/A blows

Thanks Arkmage and Dan. I assume I'll have to get a reduction coupling in my case.

In every sense but literal. :giggle:
