Fitting 3.2 mv6 from Omega in to Astra mk3 van with a Calibra 2.5 V6 c25xe ..
Ianpinder:
Hey guys, I’ve got an Astra Mk3 Van with a Calibra V6 C25XE engine in, now I wanna buy an Omega 3.2 MV6 engine, Is it a ball ache to fit or really easy?
Doctor Gollum:
Keep the 2.5 wiring and sensors and manifolds and it will drop straight in.
Ianpinder:
What about the ECU …. The bigger injectors on the 3.2

Sure, you can fit the 3.2 injectors, but why make life more complicated...
The Astra and Calibra had cabled throttles. The 3.2 doesn't so you need alot more than just the engine if you go down that road.

The engine is otherwise essentially a bigger bore version of the C25. Dropping a bare 3.2 in would essentially be akin to swapping in another C25.
The ECU should allow for the increased air going in and add fuel to compensate.
