Like this correct?

That is a stock N/T throttle body. The blade diameter is 60mm same as a turbo throttle body.

So its not the 63mm throttle boby?

No stock throttle bodies were 63mm, and neither is the one you posted (stock 1g N/T). All 1g (turbo and N/T) came with 60mm bores. The only way you'd have a 63mm bore is if you bought one specifically from Steve Monroe.

As I mentioned in the PM to you, a bored one will have a shiny/reflective bore and plate, just like the picture in post #2.

Oh ok so how is this not 1g nt how can you tell?

 

[snowborder714]

I'll just reply to the thread so everyone else can see and help out. No sense keeping this info holed up in a PM.

I measured the back side of throttle body and 59.55mm is what it says[DOUBLEPOST=1407968107][/DOUBLEPOST]So i guess its just a 60mm bore stock. I got it from guy and he said it was nt 63mm bore. Its a nt 60mm bore correct? And were is best place to get seals?

 

[snowborder714]

Yup, then someone "bored out" just the inlet. That is a stock 60mm throttle body, not a bored out 63mm unit that you'd get from Steve Monroe.

If you're looking for just seals, there are a few places. ExtremePSI, MachV, STM should all have at least the normal seals, if not some version of a metal cased/mil.spec seal. If you're looking for mil.spec seals, just buy them directly from the person who supplies them (Google it - there's a thread on EvoM about them and how to purchase).

 

[DSM_GSX01]

Thank you snowborder. Will find seals.

i too have the exact TB. So i cn confirm its a 1G N/T 60mm P.s Home depot/lowes/ Ace hardware has the seals, seal number #7 i believe is the one for that.
