Thread: turbo vs gas injection in 3.9 isuzu!

I would prefer to fit a turbo. Just my 2 cents worth, but I have no experience with lpg on an Isuzu.

turbo....

as explained elsewhere, in a naturally asperated engine the gas displaces valuable O2, not a problem doing it on a turbo'd engine as you can just up the boost to compensate.

And I still think its out to lunch on the cheaper power thing as they keep telling me how much less diesel Im going to use but never mention how much the LPG costs and with lpg topping 72.somehting cpl thats half the cost of diesel now adays.

A turbo doesn't need constant refilling, doesn't increase your EGT's and doesn't take up space inside the vehicle.
A turbo is also guaranteed to increase the efficiency and power of your engine without violent preignition.

Guess that's why they're soo popular.

Looks like the turbo is the go!!
What do you think it will cost to hook one up?
(already have the manifold)

CHEERS
TIM..

I have a spare non waste gated model (second hand) sitting around if you want to make me an offer.

Some have put on their own turbos on the 4bd1 and obviously know what they are doing. To me it is a black art. No idea on how to tackle it, what is required, how to modify the exhaust and how to tune it all in.
Where can I go to get one fitted to my LandRover Isuzu in Sydney?
Thanks, David

The factory ones are the easiest to fit. They simply bolt up. If you can fab your own manifolds or adaptors then you've got plenty more options.
The garrett T25 is one of the easiest to find and spools up nice and quickly.

No matter which one you pick, you'll need to sort out an oil feed and drain. Oil can be taken from the alternator, for the drain you'd need to drill through the block.

Hay Dougal, where is the easiest place to pick up a T25? New and cheap, I've been quoted around 12-1400 bare. And is the T25 got a water cooled housing?
For those out there I might be selling my factory turbo kit.
