Hail to ye all I have a 2ltr straight 4 VN with a engine from a Vectra. Its a NZ only model. I need a new engine and have been researching choices. I know that a RB30 from a VL will bolt straight in, now what about the old Australian made straight 6 from the model before the VL?? I can probably get my hands on a free black motor, will these bolt straight in? Has anyone done a conversion like this before? The main reason I think its a good idea to put it in my car is because I wont have to change my front springs because that motor looks really light and its free.
