It’s a pretty cold, wet and miserable day here in Adelaide today so not much is getting done. At the moment the mercury is sitting on 12 degrees which is unusually cold for this time of year to say the least!
What better time to sit down with a hot drink and start the rig build up post I’ve been meaning to do for the last seven years (Joined as “MickL” Feb 2007!) And besides, the old girl is being considered for retirement so better get this done before she’s gone to a new home.
Now I’m short of some photos and being out in the rain today to take some doesn’t appeal a hell of a lot! So please excuse the first couple of profile shots that were taken a couple of years ago, but you get the idea, nothing has changed much visually except the suspension has changed to near four inch lift (From what is a two inch OME kit in pics) and also she no longer sports her factory side steps which are rock magnets.
I’ll start in the engine bay, only because I have an up to date picture and what better place to start than under the hood!
Now the engine in question is a 1kz Turbo diesel, backed by a 5 speed manual gearbox and you may cringe but I bought it on purpose in spite of the 1KD being shortly available at time of purchase.
Why the 1kz? Well for me it came down to the fact I know this engine well and can work on it with my eyes closed. Which makes it very suitable for our solo vehicle style of travel.
Of course this engines a bit of a dog power wise especially in a vehicle the size and weight of a 120 Series Prado so some modifications were in order early in the piece.
Starting at the airbox; the pre spinner has been removed, all edges radiused and a Finer Filter installed.
The restrictive intake hose has been replaced with silicone hose and the resonator box removed.
A CT16V intake has been fitted to the turbo.
The throttle plate has been deleted, and the EGR disabled. Also a catch can has been fitted.
The intercooler has been fitted with a fan that is controlled by a frequency switch running off the ECU speed sensor.
A shuttle valve style boost controller is fitted which prevents waste gate creep and I run 18psi of boost.
A 3 bar Denso MAP (boost) sensor is fitted to defeat the fuel cut and a Dtronic with modified fuel map helps the ECU run the show.
Exhaust exits via a HTC coated dump pipe and Beaudesert exhaust system.
Other engine bay goodies include and ARB air compressor and Optima cranking battery. The second battery is a 130AH SSB controlled via a DB180 Piranha controller.
Sitting in the workshop but unfitted is a larger intercooler, current Hilux scoop and yet to be modified intake manifold.
Also the Dtronic is unsupported by anyone these days so a new chip would be nice to allow a new tune, the current tune is only for the exhaust.
Fuel economy is still flat 11’s despite the outside kit and my driving style which is less than economical!
