Subaru's new new boxer diesel is an alloy block..
I cannot see too much of an issue the manufaterer making diesel's in these style of blocks ??..
Yes some re-engineering needs to be done.. But in the past diesel's where regarded as heavy duty motors..

could use a diesel block. I think it could handle it, as for the engineering required, don't bother a 4.5L twin turbo toyota Diesel can be had, check out VDJ200 series, for the twin turbo and single turbo is on VDJ70series.

Interesting we all speak of 22:1 compression ratio but if you'r running 9:1 (like me) and then run 22psi boost (like me) the actual compression ratio is over 22:1 when on boost.

On that basis the block/rotating assembly can sustain the compression.

I was thinking that exact same thing, then its a simple matter of the right heads/cams/valves/fuel inlet and tuning, which would be acheivable, but cost prohibitive. VD series for the win.

Agree a pointless excersize when so many good, and proven, diesels are available at far less cost.

I wouldn't even contemplate the engineering and cost involved to try it.

I seriously doubt it could be done.

Assuming it could be done I would think Toyota would have had a 4litre diesel V8. It would have been handy for them.
Not true, there are diesel engines that are running under 14:1 to control NOx.

Just one example.

whatever

Toyota has diesel V8s, been around for close to 10 years now.
4500 cc turbo charged, comes with 1 or 2 turbos.
Great stuff. roughly 260 hp roughly 750 Nm.

As far as I know they can be found in large Landcruiseres, Lexus 570 and some pickup models.

These mills may be found almost all over the world.
But not in the 2nd largest Toyota producing country, Thailand. Pisses me off, 'cause
I want a 1VD and I stay in Thailand.
