Turbo for GQ Diesel with big kays?
Turbo for GQ Diesel with big kays?
I am considering having a turbo kit fitted to my 4.2 Diesel GQ wagon, it has done just under 450,000k's and hasn't had a spanner on the motor, gearbox or transfer case. What are the pitfalls of this with that many kays on the clock, will it bother the old girl?
Re: Turbo for GQ Diesel with big kays?
you have checked the images of Woops rebuilt TD42 below?
550,000 and still see the original cross hatching in the bores...
But then, I wouldnt put one on at 550,000klms.... asking for problems.

Thanks for the replies, it has been serviced by the same bloke religously from brand new, it belonged to my dad who is fanatical about servicing (gladly I have inherited that), who put about 400,000 on it and then I brought it off him. Has had a set of injectors done a while ago and that is all, has been a great vehicle. Just would like a bit more punch for towing and 4WDing, so thought turboing it would be the next step? Any other suggestions?

Nitro.
super charger.
extractors, free flow exhaust.
snorkel and no pre cleaner and a good air filter.
up the injector pump.

LOL.....I did turbo it, actually I turbo'd it at 505,000k's and am still flogging the piss out of it, running 12psi of boost and pump turned up, its still going as good as ever, just keep the oil fresh is the trick. It gets a little bit hot doing circle work (will post up a vid soon) but thats to be expected! 454 going in very soon.ratbagpatrol wrote:bang is the only word that comes to mind i would not do it at that many kms
Absolutely a great example of how tuff they are, that motor is still going in that truck down here, and it really goes too, i think the new owners won vic winch in it didn't they?chpd80 wrote:Ask Daniel at Rally how much they put Chris Richters td42 through when they raced it, Think that had well over 400,000 on it got well thrashed and is still going.
25psi. Thats crazy mate. Has the engine had any work done in that time? Bearings or strenghtening of any sort?
I'm hoping to run about 15psi with the use of water to air cooler. If the standard GU pump will keep up.
Should know in the next week or so when finished on the dyno.

Thirsty GU. TI, 4", 33's, factory locker.
no work when i first put it on did not even have an inter cooler for 12 months but after 24 months or so ported the head as wanted more power as for bottom end has never been touched still going strong is dayly driver on free way and weekend it just gets thrashed oh and stock gq fuel pump
it will go or it will blow

never understand that.
i'd be more worried about the condition of the bearings and crank journals and the condition of the oil pump.
sure with worn rings it wont make as much power, but it's hardly going to make it explode.

They talk crap. That would mean you should pull your turbo off at 250K or rebuild the engine every 250K. These aren't Toyota engines do they realise? The TD42 was a turbo built engine from the start designed for small buses and light trucks. My mate just put one on his TD42 its done over 500K.money_killer wrote:some companies do not reckon putting a turbo on engines with 250k + but i would just give it a compression test and make sure the motor is A1 ....

The companies that suggest this are smart.money_killer wrote:some companies do not reckon putting a turbo on engines with 250k + but i would just give it a compression test and make sure the motor is A1 ....
"You fitted a turbo to my motor and now its thrown a rod, I want you to fix it"
Its for liability reasons.

Mine with 290,000 probably should have the turbo removed!
Do a comp. test and take it from there.
Standard turbo with fuel and boost adjustments shouldn't be too much for it.
Standard pump is supposed to be good for 130kw so I'm told, early GU anyway.
