Thread: Specs on 4BE1?

Hi

A 4BE1 with 135kW ? Wish I had one of those.

A comparison of the 4BD1, 4BE1, 4BD1T is as follows

Model kW @rpm Nm @rpm litres
Isuzu 4BD1 66 3200 245 1900 3900
Isuzu 4BE1 74 3500 242 2000 3600
Isuzu 4BD1T 90 3200 314 2200 3900

The 4BE1 was found in the NKR Models (150,200,250,300 & 400).

I don't have any manuals despite looking from time to time to buy second hand.

Quite like the engine. I've never been able to tell it apart performance wise from the few 4BD1's I've driven, but my mechanic tells me the extra 300 RPM in the redline for the "E" is an improvement over the "D" on the highway.

I run an LT-95 gearbox with the 0.996 transfer case ratio. Cruises at 100 OK but when I towed my Camper Trailer around Oz, certainly was tricky overtaking and a slow on hills.

My 110 was originally a V8 and the conversion was done by the previous owner. Donor engine was from a 1989 NKR Council truck that had rolled.

The adaptor (plate, flywheel and spigot adaptor) was sourced from Zenith Engineering. I believe they no longer stock the kit. Engine and gearbox mounts are Isuzu, rover items were deemed too small.

A 12V alternator with vacuum pump was fitted and the starter modified from a 12V Thermo King. I believe the 12V 4BD1 starter is a straight fit also. The starter needs to be rotated 30 degrees so it doesn't foul the chassis.

I've never connected the 24V glow plugs.

The sump has to have a piece cut off one corner and rewelded to allow the clearance on the diff.

I cracked the casting on the original 3-bolt power steering box as the 4BE1 PS pump is too high a pressure for the box. A 4BD1 pump from the army was fitted with a lower pressure and a 4-bolt box was fitted.

I have a set of extractors fitted.

Would like to turbo the engine, but do not want to lose my County Aircon which would need to be sacrificed space wise to fit the turbo.

I doubt I'd ever sell this vehicle as I like it so much.

Happy to assist with other questions if I'm able to answer.
