92 MK3 TRANSIT 2.5DI NON TURBO DIESEL ENGINE - UPGRADES PLEASE :

Looking online , apart from a service . I have seen that you can change your diesel pump from a lucas to a bosh which helps ?

its a camper and struggles to get to 55-60 at the moment .
any info on the Bosh upgarde ie , parts needed , method and so on would be really appreciated ,
Anything else that can be done to help with power on this engine?

A bosch won't help a non turbo engine. Lucas pumps are often slightly better.

They are slow... its part of what they are

If it's a camper,why be in a rush to get anywhere ?
Think positive thoughts and enjoy the ride...........

How can you enjoy the ride when you’re changing gears all the time .

20 years ago, I traded in a MK3 with a rotten body and a showroom engine for a Lada.
It took me the fall, winter, and spring to reassemble the engine and get the car running. I took it for the first time on May 24, 2006, my birthday. I was 52 then.
Since then, the car has just gotten better and better!
In 2014, the engine "showed its brotherly hand"—a piston pin cracked in cylinder number three, and a connecting rod pierced the cylinder block. Assembling the other engine took two months, and in 2015, I installed a turbocharger on the naturally aspirated block, or rather, on the block with naturally aspirated pistons. At first, I had a simple naturally aspirated Bosch fuel injection pump, then I was given a Bosch with a turbo corrector, but in the end, I chose the naturally aspirated Bosch, with only one setting changed—I tightened the turbo corrector screw almost all the way down. This provided high torque at low rpm, which significantly eased driving.
In the summer of 2022, I replaced the rear axle with a 4.56 gearbox with a rear axle from a 2007 model with disc brakes and a 3.31 gearbox.
This is a very "heavy" gearbox; the engine simply can't handle it without a turbo.
A 3.9 or 4.1 gearbox would have been ideal.
I bought a 4.1 gearbox, but I don't want to replace the rear axle. The factory setup included a "narrow" rear axle and a 4.11 gearbox, but the teeth started to fall out, so I installed a "wide" axle with a 4.56 gearbox.
With the "narrow" axle and the misadjusted fuel injection system, I reached 140 km/h, with the "wide" axle, 120 km/h, and with the 2007 axle, I reached 140 km/h again. Any more is scary.
If the car doesn't accelerate above 60 km/h but starts well at temperatures below 0 degrees Celsius, then the fuel injection pump needs to be adjusted or replaced. If the engine starts poorly at low temperatures, then the engine and fuel injection pump need to be diagnosed and repaired.
White smoke from the exhaust, sluggish acceleration, smooth engine operation, and poor starting can be caused by incorrect injection timing or late injection. It's difficult to accurately diagnose an engine based on a single forum post.
But if you ask a lot of questions and follow some of the recommendations in the answers, you can improve some things.

my di has a lucas pump and does 85 mph, just need to use the gears a bit more . i have been in so many peoples cars and vans that stay in top gear going up a hill then change down a gear when its to late with a load of black smoke out the rear.

The only Di's i've ever had that would do over 75 had the taller minibuss diffs in them, they dont like to rev that high IME but they will pull a higher diff ratio

The only way to add performance to this camper is by installing a turbocharger and tuning the fuel system.
I already wrote here that I bought a 4.11 rear axle.
Now I want to return the old 34-speed rear axle to the car. The car starts slowly, and in the city, 4th gear is rarely used; 2nd and 3rd gear are usually used. Fifth gear can only be engaged on country roads at speeds of at least 85 kilometers per hour.

Please stop repeating the myth that minibusses had taller diffs... its just not true! They all had the same options. the taller diff is a bit more common in minibusses, but its still (from my experience) only 5-10% that had them
