Got this site address from my brother,(Warthog) it's pretty cool.
I am in the process of preparing a OM 602LA engine to be fitted into my S2A FC.
The engine is a 5cyl 2.9 turbo intercooled Mercedes Benz engine as fitted to Sprinter vans. It puts out 120Hp @ 3800rpm and 280Nm @ 2000rpm.
The unit will at this stage be mounted to the std FC transmission as I don't want to loose the PTO and hydraulic winch.
I will at a later stage fit a standard S2 transmission after modifying/locating a PTO. Another alternative would be to fit the much stronger Santana transmission as installed in the South African built S3"s". (The PTO of the FC differs from the std transmission as the FC has a totaly different transfer box. This results in the mainshafts also being different.)
There are different variants of this engine. Ssang Yong use a 602 which is naturally aspirated and fitted with an inline injector pump whilst the engine I am fitting is turbo charged and originally fitted with an electronically controlled rotary pump.
The first item on the list is to get rid of the electronics so that the pump operates 100% mechanically. Fitting an in-line pump is not an option as the injectors used with a rotary pump require a higher pressure that those fitted when using an in-line pump. There are no mechanical rotary pumps available for this particular engine type, therefore a special injector pump was built using the fuel head and internal components of the original pump. The housings and governor apparently originate on an Iveco injectror pump.
A problem was encountered with the 5cyl cam plate inside the pump but I would at this stage rather not divulge what was done to overcome the problem! What we done most definately will not carry the blessing of the OEM.(Bosch)
The pump did performed faultlessly during it's 2 hour stint on the test bench whilst callibrating. You may ask why 2 hours. The answer is simple - There are no specs for the pump as it is a hybrid and the time taken was to get the Fuel delivery curve identical to that of the electronic pump.
I've gotta run but will continue with some more details later.
