Wanted QLD 70mm Throttle Body

[Smurph]

I'm under the impression the FL auto models came with a 70mm throttle body and I require one, willing to pay postage.

Thank you

not all, seems it varies on which model came out with the bigger TB and plenum TB flange ID..

you can get the magna ones which may be a cheaper option

I've found the 70mm on a manual, I have one I'm waiting to fit to my car. Steve honestly reckons there is no performance to really be had from the larger size. Maybe 2-3kw at most. Make sure I have the larger plenumn or be able to die grind it out.

Throttle response is the advantage of later TB but hardly noticable on our cars. Best off spending time and money elsewhere addressing bottle necks.

What's the inner diameter on it, @trotty ? I've got one here with an ID of 67mm.

Ok. Sizes I have are as follows.
Large TB 65mm

Small TB 60mm

Large TB on small opening manifold

How to tell without removing the throttle body is the angle of these outlets. The angled that point up is the large TB

Small manifold opening. 61mm

Visual differences from the back.

If som1 can be bothered to make a thread for the info section it would probably be beneficial to others for quick search.

Yeah I'm redoing my plenum for the hot side so I figured why not
