I'm curious if anyone knows what exactly Vx did to detune the 2.5 engine to the 131bhp? My mechanical friend tells me that there were 2 different 2.5 engines put in the BMWs... One was a 131bhp in the TD and the other was 143bhp in the TDS models.
So am i right in thinking that the Omega and lesser spec BMW engines are pretty much the same with the only difference being in the TDS model BMWs?
Anyone know the difference between the TD and TDS models?
I had a BM 325TDSE that I used pot around in moons ago Paul, good little runners when they weren't breaking down, smoking, leaking oil and pissing fuel all over the place.
As you say same straight 6 tractor engine, but the S / SE had a bit more power, made a big difference as well, as far as I know was only difference was the Oil Cooler and a different map in the ECU, did hear once that the Turbo was slightly bigger as well but never got that bit confirmed. Mine was remapped up to about 180 bhp (Robann Techniks from memory), again just a tighter Map on the ECU and Boost pressure changes, did bloody fly though and really good on fuel, but the 325 were a lot lighter than the Omegas.
Appart from the Engine, the other difference was the SE were lowered, slightly stiffer suspension and had a different body kit around the bottom which was colour coded to the rest of the car rather than being unpainted grey / black.
A said good runners when they worked, but as most BM's when the pack up, the do it in style.
You can get up to 200bhp out of the SE Lumps by messing with the Map and Boost Pressure but they dont last long in that form if abused or not maintained correctly.
