Builds BUILD THREAD - KZJ78 - Lenny

[Lenny33]

She is a pretty dependable runner now. After EGR delete, manifold clean, new fan and fan clutch, new t-stat, and adjustments to boost and spill control it won’t go over 200F for water temp and EGT tops at about 1100F if I am pushing it pretty hard up a hill (quickly goes down in temp if I back off).
I am pretty happy with the way it is running and would trust it driving on a long trip.
She has come a long way with my scrapes knuckles and the board’s knowledge!

I'm just curious about the hill-climbing issues you are having. I don't know much about diesels or turbos.
The EGT temps you are experiencing, are they within stock parameters?

It just seems that, as you've been base-lining things, they've been improving. I was curious if you took all the OEM-spec stuff back to stop adjustment values would see a better situation? Albeit perhaps less overall power. But then you could tinker with everything from a stock, as-Toyota-intended, position. Or was the stock setup prone to the EGT issues you are finding?

just touching base on this again -
I may have been chasing my tail a little for a while, but I finally kind of returned all settings to a more “stock setting” and then began tweaking again.
She runs well now and I can drive 60 mph up a steep hill in the thin air of Colorado, if I had to, but I usually keep it closer to 55.

Kids got a ping pong table for Christmas and the Prado has been sitting outside for a week. Cold start, not plugged in, a week outside without being ran, and it started up in 12 degree temp. Not bad.

Attached are results of the first two emissions tests on the Prado after I received it and results of today’s test.
CRUSHED IT!!
I would say that one year later, she runs a lot cleaner!
Thanks guys!!

Great job with the build!

Thanks - getting a little sad about the thought of letting it go. My wife needs a better job so I can afford all my toys!

Thanks for sharing your build! I too owned a KZJ78. They are cool trucks. I’d love to see it if you still have it. I’m in Arvada. Here’s a picture of mine.

Love your rig and build! I’m in boulder. Love to see it sometime. I’m in market too if you’re keen to find a new toy and sell this one

I guess I should mention that I no longer own this rig - sold to a great guy in WA. LOVED this truck, but it was not meant to be a daily driver and a camper puller. Miss my Prado, but love my new Prado!
