You considered a Diesel/autogas dualfuel system?
Yep the same on an Astra. You will need a 10mm bolt and a 13mm bolt to lock the cam and pump pulley. Take off the spring thats on the tensioner, loosen the pulley and remove belt. I thought it was a crap job TBH.
The best thing to do is chuck all the crappy asthmatic air piping and get yourself a nice cone air filter which will fit about 40cm away from the turbo! Loads of cold air gets in as the cone will still fit at the front of the engine to get the cold. Makes a really impressive noise as well!
If it's the Isuzu engine you'll see that the pipe that carries the pipe from the turbo to the inlet has a connector before it goes to the top of the engine (the black cover). Diconnect it there and fit the cone. Green actually make a kit for this and is what I am runnung. I would recommend.
yep autogas is lpg. you add about 20% (mechanical system) lpg to the amount of diesel being injected and this causes the diesel to burn more completely, (normally 15-20% is wasted) and also you get the extra power from burning the gas. With a mechanical lpg injection setup you will see a fuel cost saving of between 5 and 20% and a torque increase of about 15 to 20% And with the electronic system with knock sensing etc... I will be supplying in the new year you will see fuel cost savings of 15 to 40% and a torqe increase of 25 to 35%
