I'm not making this to compete with the one on VXON, I'm just making it because I'm bored.
There are two stages to this.
1) Removing the white ring from the fuel pump. This can be done in it's own for a nice increase in semi-open throttle response.
2) Increasing the boost and upping the fuel.
1. Removing the white ring.
The fuel pump on Cavaliers with the Isuzu engine is underneath the inlet manifold. This means the manifold has got to come off.
The collection box on the top of the manifold is secured by four 6mm bolts with 10mm heads. The air filter is also in here, the one that people forget about.
Once this is off, you can remove the hose to the air box which is held on with a jubilee clip, and the hose from the other side.
The manifold itself is held on with torx-headed bolts (some longer than others, so remember which ones are from where). I didn't have any sockets to fit, but IIRC a 5/16th socket fit very tightly.
You might have to loosen up the union on injector one to get a socket past it.
The easiest way to see what needs removing from the bottom edge of the manifold is by using a mirror, or I used my phone with the light on. There isn't much space down there, and there will be swearing,
You will have to remove the feed from the turbo as well, this is simply two bolts, but they are a pain to get to and they are different lengths.
You will need a new inlet manifold gasket and a new gasket from the manifold to the turbo feed.
