here's a guide I wrote years ago on the old club g40 site, I guess this needs putting in the FAQ section, for some reason I thought it was already in there:

I also replaced the rivets with liquid metal at some point too, a bit less restriction in the airflow and a bit less likely to do damage if one was to fall out.  If you do use liquid metal then put a chamfer on both sides of the holes so that when the liquid hardens it's basically hourglass shaped.  I have a 51mm throttle body now though which doesnt have any holes in it, I think I gave that throttle body to pete.

im guessing this is irreversible?

[jez1272gt]

yeah it will be if you use liquid metal to fill the holes, unless you want to muck about redrilling the holes etc or get another throttle plate? If you use rivets then i dont see why you couldnt carefully drill them out...

i was thinking of getting a spare throttle body and de wedging that so i can interchange em as and when i want!

a while tb unit will cost you 50-70 pounds i think - for something you will probs never swap over again..

if your spending money on a tb wait until a 51mm gets put up for sale!

often the thread in the wedges deforms or the screw snaps in them when you remove them - not always, but there is a risk

[G40supercharged]

The ends of the screws holding the wedges in are punched to stop them dropping out. That tends to wreck the thread in the wedges when you unscrew them.

You say the wedges are there to aid at low speeds and smooth set offs, is it really that bad when the wedges are removed?

Would it be worth it for the extra power you're getting?

lol sorry mate, do you mean you didnt notice a difference in power or a difference in the way it drives [i.e. smooth take offs etc]

cheers

[PeteG40]

gaskets on inlet for gt and g40 are the same


- yuou'll find a bit more poke top end, but will be a bit more on/off when you are setting off as opposed to smooth and progressive
