Which Turbo??

Have a compression test done.
If thats OK get the injectors serviced.
Then go out and buy a Denco kit. Good instructions to DIY.
Then fit an EGT guage and off to somebody who knows how to tune it.
If its done a few Kays I recommend to have no more than 7.5 lb boost and no higher EGT than 500 degrees with the throttle flat out under load for 2 minutes.
You will be happy just like me. I have fitted a few kits now and all customers very happy.

BTW the DTS kit is also very good except with the Denco you get a full exhaust.

Hey Nick,

You've gotta be careful with the 2.8L diesel. They have weak crank shafts.
I had the engine fully rebuilt and a Mike Vine turbo fitted, whole job cost about $12,000.
Did about 50,000 km's when the first crank shaft let go. Another 1 year later the 2nd one went.
I did what any other bloke would do. Sold it to my brother.
I also have a 75 series ute and had a Mike Vine turbo fitted the day it rolled off the showroom floor. It is now on 360,000 km and the motor has never been touched.
I think the 2.4l hilux motor is a bit stronger and can handle an aftermarket turbo a bit better.
I think the 2.8l is better left the way it is.

Just my 2 cents worth mate.
Good Luck,
Brett

I was considering turbo-ing my 1HZ and decided that before I shelled out hard earned cash I would do some research. I visited 3 local engine rebuilding shops and put my questions to the proprietors, and guess what - my 1HZ is still naturally constipated and that's the way it's gonna stay.
Hope this helps.

I didnt know about weak cranks on these engines as pointed out above, so in that case, I'd be looking to do an engine swap... No use putting more strain on it if they have issues.

But then when you work out that its going to cost $10k for someone to do the work for you on an engine conversion, you maybe better to take the opportunity to upgrade the truck.

Denco turbos are great, bleep easy to install, 1/2 a day tops, and make a great difference.

Everyones expectations are different though on what you get for the power up.

I'd heard that an aftermarket turbo on a 4 litre Toyota was a good idea ..was considering getting a Troopie and powering it up. Then I mentioned it to my mechanic (a 4WDer of long standing) and he reckons that while the performance is enhanced amazingly, it ultimately kills the motor well ahead of it's time. Says the motors weren't blueprinted to handle the extra load. I'd look at the alternatives. Anyway, that's my two bobs worth.

Hi Nick

Don't mean to hijack but the subject is in my focus.

I have just bought a 3Ltr and am researching also.

Is the three litre any better than the 2.8 or is it a stroked/altered 2.8ltr and is there anything serious to be aware of before fitting a turbo and will Average Andy be able to do the fit up? Got 175K on now and curious. Can do mechanical stuff but never done a fitup like this. You may know Nick or anyone else.

Thanks
Regards
Andy

G'day Nick
I own a 2001 3.0ltr TD GXL Prado with 58000k on it and also a 1989 2.8ltr Diesel 4 runner.
The 4 runner has the DTS on it with a larger exhaust and staight through muffler and Airtech snorkel.
The 2.8 had 405000kms on it when I put the turbo on, and now has 519000kms.
I only run 7.5psi boost (thats all you need to run rings aroud a Pootrol), the thing is you have to get somebody to set the mixture and timing correctly to make them perform.
The 4runner will out run and power the Prado by a minimum of 10%.
As far as the weak cranks are concerned i've never heard of one breaking but I suppose it's got something to do with how they are driven.
I have towed my CT up to Cape York and the Gulf over the last couple of years and I can tell you they are a pleasure to drive with a turbo on them. Do it.
