hilux turbo info for Stephen M.

I said I`d get back to you so I`ve kept my promise.

Here`s the turbo fitment story for your information.

2.8D D/cab hilux Ln106 `89 model, 33" tyres lifted.

Safari turbo kit 2nd hand $1300

Bolted it on also very worried and started sweating about blowing up my motor !!!!!!!

Turned up fuel mixture 1/4 turn to allow for extra air pressure.

Ripped out old exhaust system (had to cut it in half)

Bolted on 600mm of 2 1/4" dump pipe (standard Safari system)

Cruised slowly to exhaust shop, Got new 2 1/2" press bent system from turbo flange with straight through muffler. $417 2hrs awesome!!

Beaudesert exhausts wanted $950 for a 2 3/4" system mandrel bent.
Too much for me !! might gain a few k/watts in a diesel ? I`d like to know the actual differences ?

Took it for a sunday drive 35 deg heat, aircon going, Wife and two nagging kids, back of Ipswich and back through Beauy, Temp stayed fine, Cruised up a long mild hill in fifth gear just to test it out,temp raised to half then back to normal at top of hill. Basically temp went up bugger all, cause it sits on just under half usually. IF I dropped back to 4th it would`nt have raised temp.

Got it Dyno tuned $220 by a reputable dyno and turbo expert.

mechanic says it was running at 14psi and fuel mixture was a bit lean, Timing was also fine.

Adjusted to 10psi

Dyno results before tune 64HP at wheels @ 82kph
After 75HP at wheels @ 83kph

His rule of thumb which is approximate only (75hp at wheels roughly equals 75kw at fly wheel)

Motor has 230,000 kms

Mechanic says he gets these results out of a 50,000k motor with turbo.
And I should have no trouble .

These are my personal results, and I AM NOT SAYING GO WHACK ON A TURBO.
Because I know alot of people have second thoughts about them.
It is simply are personal choice.

I just got frustrated too often slowing down other vehicles and not being able to overtake at simple times and revving its guts out climbing up hills.

But now it is much more driveable and picks up well in 3rd , 4th and 5th gears.
But the real test would be with a load and offroad.

Asolutely rapt. just gotta get a snorkel.

Cheers.

Yep got to have a turbo, I feel sorry for the poor guy last weekend in his 2.8 non turbo hilux I flew past going up a very steep hill. I was pulling 3300rpm in third in my 2.8 GU (which has not got a rep for power!!!) and he must have being struggling in second going by the smoke show coming from his exhaust! Mate at work has a 2.8 lux as well. He hates it when we leave work and I kill him from the lights with the air con on!!
If any car needs a turbo then the old lux does.......(mates has 390000 km on it and no engine work done) solid old truck!!

Hope it all goes well for you in the long run

Cheers Stefan

You hit it right on the head stefan.
The lux needs the turbo !!

Here`s a head scratcher for you.

Safari turbo site states on their graph for the 2.8 with turbo 255Nm torque @ 2400rpm and with intercooler 292Nm torque @ 2400rpm.

My Dyno report says 364Nm torque @ 2400 rpm and thats running 33" tyres ?

? Buggered if I know what`s going on there ?

Thanks for your reply.
