Alright I'm sick of it being to slow already....picked it up yesterday:eek:

Where is the best place to source a turbo and a manifold, i'll make everything else myself:twisted:

Any info welcome:)

I know a few people who have bought new manifolds straight from ISUZU for $300-350. There are 5-6 options though (2 different turbos and 3 different mount locations).

rar110 also mentioned that Zenith make them even cheaper.

Factory turbo was a garrett t25 (withouit wastegate) or an IHI (forget model number off the top of my head).

The 4BD1 T25 is very similar to the T25 from a nissan C18DET. There are a few places that sell new T25s for about $1100. Some people have also suggested using a GT28RS (disco potato - ball bearing), but I don't know anyone who has actually tried it.

The IHI turbo from a WRX is also about the right size.

G'day All, What's wrong with being slow :D:D:p my old 110 Isuzu will still the legal speed limits, but before you rush out and spend big bucks on a turbo, I would get some opinions of some of the more knowledgeable people here, mine has 450,000k's and I think a turbo would possibly damage the motor, but I'm 58 and know not much about it anyway I'm sure you will get the correct jibes here, cheers Dennis:wasntme::angel:

Mmmmm C18DET, might be able to get one from the local jap wreckers for a decent price

What flange are the standard manifolds, and what turbo locations are availabubble:)

Standard manifolds comeeither with an IHI flange of a T25/T28 flange.

I have a part number for a T25 centre mount manifold - will dig it out...

EDIT: #8943662470 should be a front or middle exit which takes a T25 turbo.

Some good info here:

Glad I didn't drive it home from brissy:eek:, Man they're cramped, will have to try and do a few subtle things to improve, already stuck on a sports wheel, need to try lift the seat, and a few mods to gain an inch or 2 back............always wanted an extra inch or 2:wasntme:

The LT95 needs to be pulled, Something is rather noisy with the clutch out, and leaks everywhere, Better watch that good LT95 itting around:angel:

Oh, it really doesn't like the 35's, but I figured that either I buy another set of tyres, or just make it turn them:twisted:, **** it dont use any fuel:cool:

I understand the turbo manifold from a 4BD2 will fit the 4BD1, if that helps.

There are a number of variations in the GT28 turbo family. Differences include the flanges.

Of the GT28 family, the GT28R will probably be best.

It is I, who was thinking of the GT28RS (disco potato). This is a bit bigger than the GT28R, but I have other mods in mind. Compressor trim of GT28RS is 62mm and turbine trim is 76mm vs 60mm and 62mm for the GT28R.

Just fitting a turbo to the 4BD1, will not give much torque/power increase until you adjust the injection pump to take advantage of the extra air.

4BD1T has a oil-spray to cool the pistons, "alfin" pistons, and a forged crank (apparently). Pretty much everything else is the same.

Aftermarket turbocharged 4BD1s in landies don't seem to suffer any problems - it's not like they are working as hard as they would be in an 8 tonne truck.

I have a Switzer non waste gate which is for a 4BD1 standard Isuzu bolt pattern. It has done 200 hours since a reco by Denco diesel in wagga.

$350 plus postage.

I am real keen to turbo my 4bd1 - just need the cash for the bits. Most I've contacted here favour the t25. Factory seems to be an IHI RHB52 or Garrett TB2515. I've also had turbo shops rec Garret t3's with a turbine AR of .50 or Mitsubishi TD05.

What about exhaust, 2.5 or 3 inch?

N/A diesels just don't get enough air to combust the fuel properly. They only work at about 80%. The Garrett on my Defender 300Tdi was crook a while ago and it was like driving a ride-on mower. You won't harm a diesel by fitting the correct turbo; just make it happy.

Different to the manifold on my 4BD1-T, but AFAIK it could be ok with a suitable turbo.

Mine has the turbo flange at a different height and angle. I may pull it off later and take a pic.

Edit: The manifold in the pic looks like the 4BD2-T. I have read of several people using these to fit turbos to the 4BD1.

T25 or GT28 is about right IMHO. The manifold has a T25 flange.

I would fit a 3" exhaust.

i bought my manifold from turboglide in woolongong for 380 ish. I am told it is off a 4bd2 or very similar. My turbo is off a nissan vg30v6 which is almost identical to one off a rb20t. Watercooled, wastegate, ball bearing, ceramic, and common as hell. It set me back 350 from SSS imports at girraween. I needed to cut and flip the dump pipe etc, but it was a bolt on with minor mods to the crank case breather and dipstick. Iit sits at 7psi normally, but i got one of those boost adjusters off ebay and screwed it up to 9.5psi. Piping would cost you a few hundred too, sillicon bends are 30 to 40 each and the braided high temp oil line from pirtek cost me another hunderd. I also got a 2.5 inch to 3 inch adaptor sillicon elbow, so i didn't have to move my air cleaner over much. I highly reccomend a pyro gauge aswell (exhaust temps) if you are even considering touching the fuel pump, its about $200 all up, but cheap insurance for melted pistons. If you want to do it cheaper though, dick smith have single imput k type thermocouple readers for around $60, and a probe isnt much either. the only problem, is there is no backlighting as its a digital reading, and they only take 9v batteries, so they run out.

Checking that pic again, it may be from a 4BD1-T that had the IHI turbo. Mine had the Garrett turbo which may explain the difference.

When putting a turbo into the 4bd1 will it need to be engineered?
Is it recommended to also convert the rear drums to discs when turbo fitted?
Also, are some of these turbo units oil fed only, or do you have to change the water pump as well?
Thanks, David.

As far as i know it doesn't need engineering. nrma had no problem either and no increase in price as it is an approuved mod on their policy. My turbo is fed water from where the heater pipes used to be, you dont need another water pump. Some turbos used aren't watercooled. Changing to a defender rear isn't worth the trouble in my opinion, unless you really really hate drum brakes. I changed mine, and i cant notice the difference. Defender front brakes however are another story.

Thanks Andy. Did you route the heater hose into the turbo then onto the heater box. Would like to keep the heater box to assist in demisting.

andrew e
2nd September 2007, 10:25 PM
what heater? :)


ive got a 12v ceramic one that plugs into my cigarette lighter, and a handy rag in my glovebox for demisting!

should be right to keep your heater though, if you put it inline with your turbo you wont get alot of flow (turbo has a small orrifice), but gee it would be a bit hotter! Give this a try and see how hot your heater still gets. It may be a little tight for space if you fit a turbo. Spose you can just build around it.

On my 4BD1-T with Garrett turbo, the water to the turbo bearing housing is teed from the housing for the top radiator hose on top of the thermostat housing.

The water returns to a tee into the housing on the water pump for the bottom radiator hose.

IMHO it would work as well if you teed into the heater hoses. The main difference is the side of the thermostat that the water comes from.

AFAIK, the IHI turbo that was also used on 4BD1-T was not water cooled.

Just a quick question can any one tell me if the turbo exhaust manifold of a 4Bd1 will fit on a 4Be1 :)
Ive been told they are the same motor just smaller pistons and liners?
