What Are The Differences Between Tb's

[john]

What is the diference between a 1g turbo and non-turbo throttle body?

Turbo's are 60MM. N/T's are 62 or 63 mm, but you can't put a throttle body elbow on them. You have to use a rubber coupler.

All it needs is a 90* silicone coupler? It is a replacement upgrade for 2g's right? I have 3 of them in the garage.

the non turbo ones really arent bigger all the way through...it just gets a little bigger at the inlet...
but yah, all you need is a 90 or 45 deg coupler to use it...
i personally like those , no chance of leaking at the TBE flange, plus simpler
