I had one of these from 88 to 99. I never saw or heard or read of one with any hotrod parts from the factory, and I belong to all the Volvo mailing lists and have belonged to various clubs and have been to meets. The real race cars were modified. These cars were just the first batch with intercoolers.

Your car may have been owned by someone who fiddled with it. I put an A grind cam in mine, along with many other parts (1990 manifold, sport turbo, HKS EVC, Centerforce clutch, locking rear, 5th EFI injector, etc.), for example.

My vote, without seeing the car, is that it needs to be sorted out by a Volvo expert. Stay away from the all import experts. No one is an expert in all imports. Stay away from the all European experts. Can't know all of those inside and out, either. Find several Volvo-only specialists. Talk to each. Do any of them even know much about 81-85 240 Turbos? Are any of them good with K Jetronic? Do any of them like working on possibly hotrodded cars? I choose mechanics very carefully. If you are near southern NH, I can recommend two.
