Hi there, I've just bought a MK3 Astra as a daily whilst my BMW goes off for works for show season. Is there anyway of getting it to roll coal? Thanks in advance :bounce:
 
Depends what motor you have fitted.

The GM diesel below is regarded to be not very tuneable (they have an alleged tendency of going pop if fiddled with. :noidea:)

If you’re lucky enough to have the Isuzu lump in the car, then you’re golden. These can be made to roll coal with a couple of easy mods.

Thanks for the fast reply mate, I'm fortunate enough to be blessed with the Isuzu engine :biggrin:
 
if thats the case then crank it up! There is an anti-tamper cover you need to remove on the fuel pump and then you can turn it up like this-

 
You can also then crank up the boost, I used a plastic 99p bubble regulator as a bleed off valve and was boosting 20-25psi for about a year without the engine blowing up :)

I may have jumped the gun unfortunately. It appears I have the GM engine :Cry: am I still able to get the same results? I'm not overly fussed about tuning the engine for power as I just daily this. But I would love for the same results as above!:lol:

I wouldn't risk it. I would strongly advise in leaving it alone as mentioned above. My above is a Isuzu, I've never tried with the GM but there have been plenty of people who have and have ended up with a broken car.
