hi there,i have an isuzu tf pick up with the 2.8 engine which i couldn't be happier with,i also picked up a 2000 3.0 swb trooper which requires an engine, i have had a 3.1 trooper in the past and also a 3.0,the only one that gave me any problems was the 3.0,(constantly actually haha) my question is,could i pick up a swb 3.1 trooper and do everything as a straight swap? also will the old 2.8 engine mate up to the 3.1 gearbox?(i don't think the 3.1 or 2.8 will bolt to the 3.0 gearbox if I'm correct?) basically what would be the simplest conversion?(not the 3.0 back in before anyone says lol) i know the older engines are down on power and torque but i prefer there simplicity and reliability,i know some of you guys have done engine swaps and i know this can be done with either 2.8 or 3.0 as i have seen them converted for sale so all input would be greatly appreciated,thanks in advance bryan |

no help or advice on this one? lol. i would like to say,i plan on doing this over Christmas and i will post pics and a run through of what i come across as i feel some 3.0 owners would be interested in maybe doing the same,there's got to be someone that can shed some light on this? i have read on some searches that the 3.0 box wont fit to a 3.1 or 2.8 but some say it will if i use the 3.0 fly and clutch?any help at all will be superb,thanks again bryan |

The only think I can help with is the 2.8 and 3.1 share the same box. _________________ Front Aussie Locker - Rear LSD - Petrol Diffs

thanks for that matski,if that's the case,i have read on 3.1 conversions the gearbox mates up with use of the 3.0 flywheel and clutch so 2.8 should do the same? that's great as i would prefer to use the 2.8 for simplicity reasons.if i can use the 2.8 or 3.1 without the need for an earlier gearbox, I'm sure i can easily keep the soft system working? (hopefully haha) i have a mate that's an autospark so the electrics shouldn't be much of a problem.thanks again bryan |

Its not so much help but I have never done the job and tend to stick to what I have done or know about avoids bsh1t that way !
I believe that the gearbox spigot shaft wont mate with the 3.1 engine flywheel ( one on eblag had it cut off,bet that drove well ) and to get the speedo to work is a bit tricky.In the manual it shows the same gearbox for the later 3.1 as the 3.0 but until its on the deck ?
There is all the wiring for the 3.0 ecu to move off and the 3.1 senders to join with the 3.0 dash and other gauges,power steering pipes ,so on and so forth .
Is there not a firm in wales who did this as a conversion for people and some posts about it on the forum ?
I would think a sorted 3.0 would be the same car to use and run as one with a swapped 3.1 but each to his own choice .
Good luck if you go ahead with it and post away but dont ask how to get the rev counter to work ! _________________ 2 New Troopers ! |

thanks for reply gribble,i was thinking of using an earlier style speedo to get around those problems,i would have thought you could take a signal from the alternator for the rev counter but not to sure? as regards to the spigot shaft in the gearbox,could i change flywheels and use 3.0 clutch? thanks bryan |

tap into the alts windings might work depends on the calibration ,Komatsus do that on the Hitachi alts they fit will put a pic up .
The 3.0 is a DMF - dual mass flywheel and if you look at red robbos posts you will see that the damper is in the flywheel and the drive plate is plain but on the 3.1 flywheel its the other way round.
You can machine down the shaft to fit or bush it up I would think. Or cut it off Pretty sure you cant swop flywheels .
The 3.0 speedo signal comes from the ECU not sure what would happen if you put it to the 3.1 dash from the sensor on the box . _________________ 2 New Troopers ! |

thanks again gribble,i think i may be far easier doing a gearbox swap as well then,but do all the hubs etc change over? as it would need to swap from the button on the dash to gearstick only for the 4x4 system,obviously needing to use freewheeling hubs.i have heard early 3.1 troopers would make a more simple engine conversion as they only need a stop solenoid wire to run engine(and glow plug timer switch)and a pedal to take a throttle cable.don't get me wrong,if there is any way of adapting the 3.0 gearbox setup,that would be the way to go |

gribble,just reading one of your replies above,dont you say(or the manual) that the later 3.1 uses the same gearbox as the 3.0? if so there must be a clutch flywheel setup to get it to work?sorry for the crazy amount of questions on the go by me here lol |

I think that the push-button 4x4 rather than lever is the same box just with a remote actuator stuck on where the lever would have been so it may well be possible to swap it over. _________________ Phil

Yes , the 3.0 has its own flywheel, clutch plate and cover and the shaft matches them and the 3.1 has the same but its not a DMF flywheel on a 3.1 so the dimensions will be different.
The gearbox proper seems to be the same _________________ 2 New Troopers ! |

You might be right Matski but I have no idear when the change was only done a few clutches on 3.1 ones with a standard flywheel bout a P reg was the last . _________________ 2 New Troopers ! |
