Also. Direct injection engines run a whole lot more timing advance than indirect injection engines do.

Back then Toyota stretched the FTE intervals out to an enormous 7,500km. Because the FTE ran a whole lot cleaner than the earlier engines. Less soot in the oil. Note the progression in oil standards. CF oil on that chart is C for...

Bigger turbo and injectors will only help when you've got a bigger injection pump. Stock doesn't have much head-room: OM617 Performance Review - https://www.4btswaps.com/threads/om617-performance-review.74457/

Interesting, thanks. How is your Hilux for fuel economy? Do you have ad-blue? Here we have only the 2.8 1GD without ad-blue. Fuel consumption isn't great.

All engine oils these days are dual rated. They have a spark ignition (petrol/gas) rating and a compression ignition (diesel) rating. They are all majorly better than they were 30-40 years ago. Diesel engine oils used to be better at handling...

Just getting into a a 3B and know about flat tappet oils from the 2F cam history. Based on what I see, Mobil 1 Turbo Diesel 5w-40 is the way to go. Good start up weight to quickly build pressure and a nice zddp package. A little pricey oil but...

For all the work in sourcing parts, modifying pumps and turbo's, finding adapters and transmissions, why not just go all Toyota. 1hd-ft or 1hd-fte, h151 5 speed. There's nothing unknown about these combos. Everything is bolt in. Spare parts...

The solution to your oil queries is right there ^^. Use that for your 1HD-FT and your life gets way simpler. The only reason not to is cost. I use a Motorex 5W30 that's VW approved for all my newer engines and a cheaper 10W40 for my 4BD1T. All...

I'd use 10W40 and minimise your oil stores.

That'll be pretty sluggish in your winters. If you plug-in or garage you should be okay.

I've put the performance review link in the post above. 300Nm and 110kw is the limit for the stock injection pump. 220 ft-lb and 150hp.

What's your end goal and reason for swapping to diesel? This is starting to look like an incredibly expensive way to get very little difference in fuel economy or range. A maxed out OM617 with better turbo still doesn't have the power or torque...

All modern engine oils do dual duty. Mobil 1 Delvac is has an API SP rating for spark ignition engines and CK for compression ignition engines...

I would tend to agree, the 617 doesn't seem like it would be a good fit for an 80-series. A 603 or 606 would definitely be preferable, but with the right efforts a 617 powered 80 would likely be quicker than a 3FE. The G was a pig in terms of...

Makes perfect sense to upgrade an existing one in a G-wagen. But not so much to shoe-horn one into a bigger and heavier Toyota first. Indirect injection diesels are on average 20% less efficient than direct injection. The most efficient petrol...

I don't think the torque, power or efficiency of an OM617 will work in an 80.

You'll be smoking like a train to get a non turbo diesel to 650C.

Adding boost increases compression temperatures and burn speed already, so advancing timing more is a very bad thing. Especially on engines that weren't intended to be turbocharged. EGT is only an indication of cylinder temperature. Advancing...

Plenty of other good brands. I would stick with viscosity over brand. I find cranking is faster and oil flow comes up far quicker in winter with 10W40 than with 15W40.

10W40 for year-round use in your climate. Pick any decent brand/spec of oil. They're all better now than they were 30 years ago when they wrote the FSM.

HA!! He was right to page me, I am an expert at blowing up non-turbo B series engines with turbos. By expert I mean I have done it twice before I gave up and swapped an Isuzu 4BD1T into my troopy... much better fit. @AirheadNut is correct, I...

Reasons this won't end well. Your engine isn't strong enough to take the cylinder pressures or crank loads. Your turbos are too close in size (flow) on compressor and turbine. Your injection pump won't have enough fuel. @gerg on here compounded...

The video directly above is a very good comparison. Same weight (they ballasted the ute to match the wagon), same trailer dyno attached, same day same track. The 4 cylinder stomped the v8. Because more torque (500Nm vs 430Nm) and more gears (6...

Any word on fuel useage?
