Thread: Isuzu 4bd1T in an Italian Defender 110

Do it if you can I have 3.5 and 3.9 V8's, A 300 Tdi, and the 4BD1T. The Turboed Isuzu is like getting off a 250cc two stroke motor cross and onto a 600 cc four stroke trial bike.
Its chalk and cheese. The latter 4BD1's like mine seem a lot smother and much quieter.
I'm running the LT85 and LT 230. The LT85 are not known to be very durable behind the 4BDI due to the torque impulse.
If you cant find a LT85 housing for the R380 you may be better off fitting the LT95 with a tapered bearing transfer idler for a wile to get you going.
There are plenty of good pics in this section of the forum of turbo set ups but if no one pipes up, I could take some rough dimensions for you to help resolve the LHD issue.

Good luck with it

Cheers Tony

Dear Guys,

Thanks for your informations, as far as I know at the moment if I can get a bellhousing for my R380 it would be the best option.
I have a supplier of reconditoned LR gearbox who's an expert, and it could build a almost bullet proof R380 for me.
If someone has a 4BDT1 to R380 bellohousing please come back to me, at the moment I'm looking for an engine also, that with my great disease seem to be very difficult to obtain here, as ISUZU trucks has the following engines: 4JH1, 4HE1-XS, 4HE1-TC.
As NPR's with 4BDT1 are too old, It seems that my hunt is very hard this time.
I'm scanning the web here in Italy to search for an old NPR.....Turbo's pipes are not a problem for me, as I shall produce my own exhaust manifold, but the real problem is getting the engine and the transmission, and then fitting them to my 1998 Defender, as I imagine that LR in Australia is not offering spare parts for County 110 with the 4BD1, or for the 6x6 with the 4bdt1.

I have a motor, bellhausing and gearbox for you, just need the turbo.
Its in the Market section.
I better not say that I am not a fan of the old Isuzu

Could send it over via boat possibly.

Typical Rangie owner, you forgot the 'at giveaway prices' part.

Almost all specific engine/gearbox parts are still available as LRAus has to keep up supply for our Army Land Rovers. The hardest part is to find a spare parts guy who knows their 3.9 Isuzu flywheel housing from a 3.9 V8 Disco one & takes the time to get what you want or knows where else to source it from. They are out there though.

This is wonderful, is a pdf parts list available at Land Rover for Isuzu 3.9 and transmission ?

Big Guy: I looked at the market in the forum, your offer is interesting but I'm lookin' for 3.9 turbocharged, would you split your offer for the bell housing and transmission ?

Ciao
