Hi lockey lux,

I'll start by saying I am no mechanic but I have done a bit of research and experimenting with the turbo on my GU. Also done a lot of research on a blower for my 100 series many years ago now.

Denco Diesel in Wagga have a pretty good reputation and I would reccomend a chat with these guys to get specific mechanical answers regarding your truck and what a turbo will or won't do to it. A lot of bad news stories come from people who have not had their turbo's set-up right from the word go. Not saying all bad news stories are like this but plenty are. The strength of your particular motor (from the factory) determines how susceptable it is to a "bad news story" when a turbo is added, also how old it is and it's service schedule so a lot depends on your circumstances and is best answered by someone like Denco.

Blowers...well what can I say, you will need plenty more folded (4 or even 5 times more) to get one of these babies forcing air down your truck's throat than the average turbo but, you will get more torque from idle than any turbo could ever hope to give you. I think if was an even par cash wise, we would all be driving around with blowers instead of turbo's (they add a new dimension to your motor) but blowers just cost soooooo much more so most of us can't, or won't, justify the extra cash to get one installed.

Best regards,
Trevor.

i fitted a blower to my GQ 4.2 diesal patrol at about 180,000 and now has done 360,000ks it cost me $5500 8yrs ago, but it has been the best money spent, the tourge from idle is fantastic and is so user friendly when in the bush, if u can afford it go for it and they are more friendly on motors with higher milage.
