I have noticed that my calibra 2.0L 8v has no oil cooler on it, should there be one on this model. If so could i fit one, and how much could i get one for. And also fitting a oil cooler would it make a difference on the performance.
My 8V Cav SRi (130 SEH) didnt have an oil cooler, neither did the donor GTE for my car. But then the smaller engined (and older) Astra SRi (1.8SE) did have an oil cooler! So it's a bit of a mystery to me!
