2.0 to 3.1?

[lee771]

Just looking for peoples thoughts.

I have a trooper 3.1 that I've blown the rear diff on, but got a bloody good engine.

My swb 2.0 is running well and engine is sweet but toying with the idea of (getting a mechanic to) dropping the 3.1 in to the swb then putting bigger rubber on to make up for the gearing.

Are there any major head aches with this conversion? I'm pretty sure most of my dash would be useless afterwards, and have heard the fuel gauge ect wont work, what about clutch and gear box ect?

Any info or advice would be great even if its just to say I'm mad and should leave it alone. Just like the idea of a 3.1 swb and I like deep water, so diesel would be better.

Thanks

You would be better swapping the gearbox as well. They are different. Then you would be having to modify the propshafts as well. You will also lose the rev counter as the 2.0 takes its feed off the alternator, and the 3.1 off the fuel pump. I would transfer the 3.1 gauges across and swap over the relevent wiring as well. Different fuel tanks as the 2.0 has an in tank fuel pump. You might be able to swap across the trooper one.

I mean everything is doable, but for the sake of a rear diff I would just change that on the Trooper and have 2 working trucks. If you are really desperate for a Diesel A Series I would just buy a 2.8.

And you'd be needing to do something about diff ratios, too.
One member a while back dropped a 2.8 Trooper lump into his 2.0, and while it was running quite happily, the diff ratios on a petrol car meant that anything above 60 MPH was pretty much redlining the engine; the other end of this meant that if you put the car in first low ratio, you'd be outpaced by most tortoises.

As above. Speaking from experience and running 31" tyres you have to change diffs on a petrol conversion.

For reference the 3.1 Troopers run 4.555 diffs. I cannot remember the gear ratio's off the top of my head.

Go get yourself another axle for the trooper, bit like the one I've got sat in my yard and no, your not having it cos it's either going to go on O-no when the clutch goes or...

Trooper LSD Axles seem to go for around the 120 to 150 mark depending on condition. Easy enough job to change over normally, the mare I had changing the one on Truck the other week was an exception.

Otherwise, look for a 2.8 or a 2.5 truck with a dead engine that you can pick up cheap and swap the engine over. Not sure if the trooper gearbox is the same or not, but the 3.1 will fit the 2.8 box. Days work to do the swap on a 2.8 if you've got the gear and don't fek about.

The 2.0 has the MSG gearbox and different bellhousing bolt pattern to everything else. Being different boxes you cannot just swap the bellhousings over.

That's just teasing!!!

"Otherwise, look for a 2.8 or a 2.5 truck withave a dead engine"
There is a dead enginelss 2.8 on eBlag and I was thinking of doing just that!! Would a 2.5 doner work? 3.1 lwb would be nice.

Had a 2.8 lab about 8 years ago and loved it.

After reading all the comments and people's thoughts I've decided on leave the 2.0 as is I love it to much to feck her up trying to drop the 3.1 in and making her unusable everydayor long distance.

Would you guys say an axle swop is do able by some one with very basic knowledge?

Thanks for all the input so far

Bleeding hecknow snapper!!!! Thank you for taking the time to Wright such an indepth reply, when I first saw it is thought "not a chance can I do all that" but after reading it it has given me a bit of confidence

And your right may as well replace the consumables while in there.

Now if a spanner party was to be thrown, I may be able to sort the use of a full on mechanic work shop, I work at a college and they have a very good mechanics block, just not sure that I would trust the students to work on my truck!! They have a few 2 posters and I get on really well with the guy that's in charge of it, if he agrees no reason why a few trucks couldn't have a bit of surgery in one go?

Thanks

I prefer...
1.Fill kettle and turn on to boil...
2.lift car by roof with forklift...
3.cut links with gas axe...axle falls onto two old tyres...
4. Lower car to floor clear of axle...
5. Park folklift, and wait by kettle for it to finish boiling and make a brew..

I dont very often do putting back together, and sadly this in not simply the reverse of above...
