4BE1 Pics

Sorry for the old thread dredge.

I'm interested in getting my hands on one of these inlet manifolds for my 4BD1T engine.

Seems this is one of at least two styles of inlet manifold that can be found on Isuzu 4BE1 engines.

Does anyone have any more information, perhaps when the change was made to this style, or whether this was only for turbo/intercooled versions, etc.?

Or does anyone know if this manifold was used on any other 4B? engine?

Or does anyone know of any that might be available?

Thanks for any information.

As I understand it, there are at least two different versions of the 4BE1 (one rotary pump, the other inline) and two different inlet manifolds. But I have no idea if the manifolds directly correspond to each injection type.
None of the 4BE's were turbocharged.

I beleive Jerry on here has a 4BE1 with the other manifold (the larger, split conventional type). I bought mine from a wrecker site unseen. I don't have the truck year or model unfortunately.
Coog (Josh) on 4BTswaps found this VIN: NKR58E-7118823

There was an online Indonesian Isuzu dealer with the parts listings for 4BE1 engines: http://catalog.isuzuastraparts.com/i...eries&type=ELF
I have a p/n 8-97064 280-1 but I don't know which type. This is 93 onwards.

John, the (1st) manifold in your pic above was removed (by me) from a late model NA 4BD1. However beyond that I can't help.

Just a parallel question: I see some have aftermarket extractors / exhaust branches, some don't.

Does a NA diesel benefit from tuned length extractors as much as a petrol engine?

I know that my 2.25 went (comparatiively) well with extractors, however I never tried with and without on the same engine.

However an NA diesel will benefit much more from a turbo than extractors.

Thanks mate.

I should be getting my Series IIIS this weekend, with a Toyota 2.4 "2L" NA lump in it , and I'll need to start thinking about getting some more ponies out of it.

It's a SOHC at least, but I have no idea if it is DI or IDI. Doesn't seem to ever have had a turbo from factory.

Anyhoo that will be a new thread under the Series III forum.

The toyota 2.4D is common over here. They are IDI, and soot the oil up like crazy (I think factory oil change intervals are 5k km???) but are reasonably reliable. There were a heap of turbo kits available over here.

It would be a good idea to fit a bypass oil filter (or better yet a centrifuge).

In all the trucks I've checked out, the 4BE1 replaced the NA 4BC2 and 4BD1, so there were no late model truck 4BD1's, only 4BE's and 4BD1T's. The breathing mods gave the 4BE1 significantly higher power for it's displacement (74kw in 98 http://www.isuzu.co.nz/media/1914/NK...20Sep%2098.pdf 81kw for 88 4BD1 http://www.isuzu.co.nz/media/1926/NP...20Jan%2088.pdf )

But what was that 4BD1 out of? Industrial may have kept using them. I know marine had a NA 4BD1 and never used the 4BE.

Sorry , going seriously OT here and on the verge of a hijack..........

I assume that means a remote oil filter system, or what?

Or a dual filter?

AMSOIL General Use Dual Remote Oil Bypass Unit

The toyota 2L-T's are notorious head-crackers. Like the toyota 1HZ they run very rich in non turbo form and require a lot of boost to first bring the A/F ratio up to a decent level and then keep the EGT down.

You need to add about 8psi boost and baseline EGT before you add boost and fuel. But then you need to be wary of the engines mechanical limits too. A vehicle certifier here told me that 3L's wear out their cranks when turbocharged (not nitrided). 2L's may suffer the same problem.
