Mk3 Cavalier Owners Club | Vauxhall Cavalier Dot Com

Looking to do some of the list of improvements posted on here (lifted from Calibra forum) on my V6, namely removal of the air intake resonator box, enlarged throttle body, enlarged lower inlet manifold flange and (if I can find one) a mantzel enlarged inlet manifold. I'm aware these are very, very rare but thought I'd take a punt and see if anyone knows where I can lay my hands on one

Also has anyone else removed the resonator box on a C25XE? Sounds easy but I might be missing something?

Pretty straight forward.

Chances are the TC motor is dead too, so that can also be removed and plugged.

The 3.0 and 3.2 have the larger plastic lower divider, great because they dont need gaskets, the orange rubber type are built in.

With some work you can also fit the vectra inlet, and have your own controller to play with the airvalves.
