    Default Anyone know the size of the z20net throttle body?

    After following Vids footsteps with the inlet manifold ive been keeping an eye on the development of fitting the 2.4 TB also. This is causing major problems as it seams the % of throttle compared to the % that the butterfly opens in the tb is not linear and they each follow there own path. With the TB fully open though no problems are appearing but at lower openings the eml is constantly being thrown accompanied by several different fault codes. On the other hand the 2.0 Super charged TB also from the USA seams to be working well with no eml. The problem is there availability and import charges.

    So then there's the last option the 2.0T TB, not been tried yet but if the opening is larger than the stock 2.2 then knowing how GM like to share components like TB's then its highly likely that the 2.0 SC TB and the 2.0 T TB could possibly be the same and with just a small little mod to the loom (basically reversing some of the wires) then us 2.2's could be on to a winner.

    So guys anyone know how big there 2LT TB is?

    Daz asked yesterday and I had a look on EPC, but it never stated any sizes Thats the only place I can look. Possibly Mark knows or can find out.
