Came here to post this. I wish that dude had a build thread somewhere.

did some checks on this but the 4bt seems way too heavy ( without additional suspension and frame mods).. The new 2.7 is what I may eventually look at when my daily driver gets replaced and the 5VZ cant be replaced ( may be a while).

saw this in person at a recent trade show. there is a company doing adaptors to mate the engine to existing transmission. however the torque may be too much for the stock transmission..
there is a similar 2.7 in the hilux 2KD-FTV may be a better choice if you can get an imported engine/ gear box.

Looks like he really had to beef up the frame to hold the 4bt. Looks like it was rebuilt, which couldn’t have been cheap.

I have a 4bt in a Sky Track ( big all terrain fork lift ) and had one in a older lift and it's a good engine for that purpose but I wouldn't want one in my 4Runner . Loud ,smoky , shaky , slow and hard to start in the cold . I would however, love a Landcruiser with a Toyota diesel in it .

I've read a lot bad things about that 2.8 Repower engine, here's an article that popped in my newsfeed a few weeks ago.

Diesel Toys loves to bash any conversion that isn’t OEM Toyota; just look at the crap they spewed about TDI conversions.
It’s also ironic that they are belittling Cummins for only being emissions compliant up to MY 1999, when NOTHING that Diesel Toys is technically legal. Lusting after a nice D4D? Too bad, not legal. How about an amazing 1HDFTE? Sorry, not legal!
I’ve heard mixed reviews about the original 2.8, but was told much was changed for the US market. Only time will tell with converted vehicles whether or not this is the case. There are few vehicles I’d rather have than a cleanly converted 1999 Highlander with an R2.8.

Under powered is a relative term. Any performance tweaks that work for its big brother (5.9) will work for the 4BT as long as you get an engine with an inline injector pump. Advancing the fuel rack 4mm will give it over 200hp at the wheels.
