The oil to turbo is from the crank case. period no special reservoir. If you want to change the oil for your turbo simply drain the motor oil. I change my oil & filter on my '93 740 hotted up 3K miles even though Volvo says 5K miles No problems
approximately 7.5 quarts
check the switch at the top of the brake peddle.
As long as the ECUs are from a NA to an NA. Don't mix a turbo and a NA. They have different cylinder compression and fuel maps. The bigger changes come after 93, so you can swap from a 90-93 ECU, and then 94-96 ECU. I know for a fact 90 and 91 turbo ecus can be swapped, I've done it.
For a 93 or 94 pry off the black triangular piece of plastic inside the door. The mounting screws are under it.
if you call Volvo with your vin# they will look it up and get back to you with the code i had to call Volvo before on my 93 240 wagon i used to have and once you get the number put it somewhere where you can find it so you can use it again if needed they can explain it for you if no luck there call 603 692 4022 they are called royalty automotive they specialize in volvos as a matter of fact that's all they work on give them a try they are located on rte 125 in barrington nh
There was a stock turbo option for the 93 eclipse. there was also a non-turbo (n/a) option.
Do you mean fuel pump relay, if so, it is behind the fuse board, White in color on the lefthand side on the last row. good luck
Yes, they are basically the same engine: BF230. They may have different turbo chargers and a different fuel injection system. They might have different transmissions. I've had a 91, 92 and 93, each year was a little different but I've swapped many parts.
BEHIND THE RADIO.
air leak to inlet manifold check small hoses the back of the inlet manifold if the hose is blocked with carbon clean it or replace and clean crankcase breather all of it.
On my '93 940T, the flasher projects from the left side of the steering column (between the blinker lever and the steering wheel). You push it in to turn the hazards on, at which point the flasher button blinks red too.
