Throttle Body differences

[MarcVIII]

I'm looking to get a 1g Tb to upgrade on my 2G. Are N/A 4g63 Tbs the same as the turbo model? I know I need a 91-94 (4 vaccuum line type). I asked the kid if his N/A TB was 60mm bore. He "thought" so. Just wondering if an N/A TB could be used for a 2g Turbo upgrade.

They are different since they use a hose clamp to hold the intake pipe on, but as long as it is a 91-94 NA TB then you can use it, but you need to fab the upper half of the UICP since the NA TB do not have a flange mounting surface like the turbo TB do.

1G NT TB's starts off with 65mm at the inlet and tappers off to 60mm at the outlet to the intake manifold.

Yeah, the NA throttle body has a taper to it. starts at 60mm to 65mm. It should be a good upgrade to your 2G.
