Thread: 4BD1/4BD1T engine bay photos?

My D90

Some photos of engine bays I have

my 110 4BD1 turbo conversion




6x6 engine bay


army 110 engine bay

thanks to everyone who has posted, my curiousity has been satisfied!

dougal, thats some damn impressive work there, cant wait to see it in the flesh!

hey rar110 what size dump pipe is that, it looks massive, maybe just the camera angle.

my 90 set-up...pre and post turbo, has changed abit again now though.

There're some interesting variations in here.

Starting with the rocker covers, the one Rar110 posted up which is completely flat on top and has no diaphragm valve under it, ones like mine with the short hump at the back and others like Larns with a longer hump.

Then intake manifolds, at least 3 of those. The one Def90 just posted up looks the best of the lot and similar to the one AndrewE fitted up not long ago.

EVERY factory 110 or stage 1 with a 3.9D that I have seen has had the flat rocker cover.

Does that make them industrial engines, rather than automotive?
Do they have the acoustic cover on the timing gear case?

The dump pipe is 3 inches. It drops down to inside the chassis rail and hangs off the v8 exhaust mounting points.

As far as I know all 110 Isuzu's have the timing cover, cover. Not sure about the stage 1's.
