On monday (31st) my car (MY02 WRX) will be going into ASG to get a VF43 turbo, AVO intercooler fitted, to get the injectors de-capped and get it re-tuned.
My question is, by this day, the car will be probably within 150km of being due the next oil change & replacement oil filter.
I have no idea what is involved with changing a turbo and intercooler, but correct me if I am wrong, but I was under the impression that at some point it will involve the disconnection one or some oil lines.
So, if this is the case, would I be better waiting until I get the car back before doing the change thus limiting the loss of my new oil, or would the oil loss be neglegiable so I should do it before so have fresh oil in the car for when the have it on the dyno???
