    Posted: 23 Aug 18 at 16:13
I bought a cambelt set to change on my DW engine, but before i came around to change it, the clutch got stuck. I was able to drive it the 350km home on shitty Norwegian roads crossing 4 smal Mountains With a lot of zig-zag roads. Not easy when you have to stand stil and the engine of to change gear. We then desided to search for a AAT engine (5 pot 2,5TDI 116hp) to fit in the Camper. 75hp in a 3,2 tonn Karmann camper is not enough in 2018. 3 Days after i started to search i found one in Bergen on the west coast. It has only done 235k km and the seller is the grandson of the first owner. On thursday august 30 i'l fly to Bergen to pick it up and drive it the 480km home. The next day the MOT expires, so il have to deliver the License plates. When i deliver the wreck at an autorised junckyard i'l get 3000nok back, and i'l pay 5000nok (450£) for the car, so i am realy happy about it. If i then sel the gearbox for 2000nok and the calippers for 1000 i'l end up geting my transportations costs coverd as well.


Now i Wonder, has any one else done a 2,5TDI conwersion to their LT?
This guy http://www.vw-lt-karmann.de/html/umbau_auf_2-5_tdi.html used an exhaust manifold from a Volvo, witch should i use? Audi or volvo?

A special adapter flange to use LT wheels (actually he is running 16" TATA wheels but they are LT PCD) on the Dana axle will be designed by me.

 A wheel dics may fit from any Ford Transit 15-16". It have dimension 5/160 too.

High protector may be solve your problem.

Hi All,

Two weeks ago me & Mecit (the owner of the LT) made a 650km trip with LT to the west coast of Turkey to see how it performs and test it, (a small holiday).

The engine pulls really strong and you nearly never ever need to down shift when overtaking or going uphill.

Fuel economy was also very good as the average was 10.2 Liters/100km.

Down side is the gearing with 3000rpm@90 km/h (GPS speed), ratios are too short.
Mecit (the owner) drove it to Istanbul and I came back to Ankara, he is now working on the "rear-axle conversion"  he will be using a US Dana60 rear axle with 3.54 final ratio.
A special adapter flange to use LT wheels (actually he is running 16" TATA wheels but they are LT PCD) on the Dana axle will be designed by me.

Thanks for reading!

wow..

thats a wicked job, so nice to see an lt getting the same kind of love as alot of t3's do engine wise.
 
i bet its still not super quick as the lt is even more square than the t3.....LOL but it must go well??
 
plus the extra power potental from these engines is great, if he needs more power you can tune them.
WHY T3's.... because they are just so adictive, and having one just aint enough

The truck is a bit too clean. If I could use it for a while I could make it proper tradesman dirty.LOL

Very nice job despite the fuse (we all do that sometimes).

Hi All,

The wiring is finished and I am testing the bus since Monday.
The ECU - immobilizer and the relays are under the seat:




The boost & EGR valves and the MAP sensor are placed behind the manifold:



I have also installed the brake and the clutch switches:



they are not seen when the plastic cover of the column is attached.

The Bus was driving well but it was giving the "start of injection control difference" and "implausible brake paddle signal".

I have altered the injection timing many times but couldn't solve it so I have visited the "Bosch diesel service" and have the advance actuator in the pump changed.

Guess what the error code is still there!

I gave up and started looking for the cause of the "implausible brake paddle signal"
I knew that two brake switches has to set perfectly synchronized, I did it but no help Confused

Than I found out that there is no +12V at pedal switches ..
It turned out that the fuse at the power line to switches are blown! and that fuse also feeds power to advance valve !!!!!

So I replaced the fuse and set the timing again and the bus is even better pulling than before!

It is so funny that I never checked the fuse before, It must have blown when the A6 had the accident as the wiring of the advance was cut and probably short circuited.


The latest view of the engine bay:

I bought the tacho mentioned here from a brick-yard member. As I recall it was around 50 gbps. Also I got the petrol engine tachometer (NOS) from a member and I paid 40 gbps.
 
Just search carefully (especially ebay.de), you'll find one with a reasonable price in the end.

Tachos are pretty rare over here, out of all the LTs I've seen I've never seen one with a tacho fitted. Mine has one now but I had to buy it new from VW as I couldn't find a second hand one!




Thanks for your comments, I am a mechanical engineer working for defence industry in Turkey. VWs are my hobby ever since.

Sadly no, this is all I got:



I had some unexpected money, so I casually enquired about availability. Once I found they were still available I just couldn't stop myself!Embarrassed

There are lots of aftermarket tachs out there but I guess most people want it to look as original as possible.
