Outer Limits 4x4 Board

Felt bad bout hijackin someone elses thread. And decided to ask my OWN question.

There is a pair of Garrett M24 turbos - off a GU 3 litre turbo diesel for sale at a reasonaqble price.

My question. Would this turbo be enough for the 4.2 ?? or even a pair of them??

Or am i wasting my time?

TOM

theres two ways of lookin at it, so here goes

if you do mostly highway driving a bigger turbo will be more advantageous to you.
if you wheel and want more grunt low down a smaller turbo winds up qicker giving you the boost at lower revs - which is what you want.

so its not a case of to small a turbo, just at what revs you will get the boost

if the garrets are a good price i would get both of em. put one on you vehicle and sell the other one.

Thanks for the response.

How does havin a pair of them work??

Or would there be no room in the engine bay for them.

Im chasing down low down torque and boost. I have long been thinkin a supercharger.. but 7k to do it is a turn off.

To make things simple... i have 36 swampers and 4.6 gearing. with a 4.2 which is being rebuilt asap and would like to see what options i have with the engine b4 it goes in the GQ.

TOM

two turbos would be alot of work
ok you would have lots of hp but look at it realistically - is there even room for two turbos

i would put one turbo in, your getting your motor rebuilt, have it done with better seals etc to handle a turbo. then you will be able to run more boost normally

better seals etc - u mean in the head department?

TOM

yeah

just so the motor is capable to run in this configuration but still last a very long time - like nissans do

Ok another question - how much boost do those turbos in the 3litre turbo diesel patrols run??? and what rpm??

and thanks sw1 for ya info.. appreciate it.

TOM

there are reasons that GU 3.0 Turbos sell cheap....

Problem with the turbos??

Pass on the info mate so it can deter me from buyin them and look elsewhere.

I know what you mean about the different types of turbos.
I drove two different gq's with two different turbo set ups and the difference was very apparent.
One was a shwitzer with only about 8psi with no muffler. The boost came on early and was quite nice to drive with a nice wistle. Would probably run out of legs a little earlier but.
The one I have now is an old safari intercooled set up with a muffler and while it goes very well especially on the highway I think it doesn't have the low down boost. It will be much harder offroad with this set up. On road it goes like shit off a shovel once you give it some. There is no where near the amount of wistle either but this may be because of the muffler among other things.
If it where me I would lap up the lower boost rpm and sacrifice the top end. It is a 4wd afterall and a bloody big one at that. We don't need huge top ends.

some of the 3.0 GU's Turbos have been blowing up.

So if i had a pair of them.. mite be okay.. blows up.. replace with the other one.

Or when a turbo blows up - does it damage the engine??

TOM

Hey Bogged..... don't you mean the motors ? from what i know that the 3.0 TD motors from the early model GU do have problems and yes they blow up.

But however the turbos off the motor shouldn't blow up ?

i agree with mad cruiser

the motors are very sensative to crappy diesel

i havent heard of gu turbs blown

turbs from current model jackeroos blow up quickly!!!!!

The actual turbo is most likly made by the same mob that does the td42t which is garret isnt it. It's just the 3lt turbo's are a tad smaller. And I dont think any of the actual turbo's have blown. But have heard that some have needed new bearings before they should have, but that may have been due to the engine dieing that has caused the turbo to go also.

How hard is it to plumb up piping to suit the turbo?? and what size would it need to be? basically an exhaust shop can do it??
