I’ve got used to changing for such lubricants for over 15 years. The most controversial is manual gearbox oil: why mineral? why engine? I had got used to use Quaker State W75 mineral but it has been unavailable for year. I had tested Midland 75W, Ams Oil and Motul transoil as well.

1988B – This denotes a change in certain systems, particularly engine management, that occurred mid-year 1988. I don’t have an exact breakdown of when it happened. Simply check the components. Primarily, the 1988B cars were Swedish market, not US market. One of the significant changes is the change, with the B202i motors, from the ignition being triggered by a sensor in the distributor to a sensor mounted on the oil pump cover. This required changing the EZK system and wiring.

The background colors in the cells are there simply to emphasize the same component being used in different years or with different systems. Colors do not repeat for each component type, but are used in different columns. No other significance should be ascribed to the colors.

Do not ascribe undue signifigance to any component changes. Often, they are made for packaging reasons, and performance will remain unchanged.

A note on the Bosch number: The Bosch number is listed as the last three digits of a typically 10-digit number. For example, a 1990 9000 turbo’s full Bosch part number got the LH ECU is: 0 280 000 586. For all components of similar design, the first 7 digits should be the same. but remember, the first 7 will probably be different if the component changes significantly.

Saab 900 turbo

What is the difference between 900 S and 900 turbo?

intercooler and intake
prime gear 7 (not 6)
APC system

APC is a system that allows you to delay the opening of the wastgate, so that instead of the base pressure (0.4 bar) you get 0.85 bar.

Factory data:

900/900S/Convertible (lpt) – B202 16-valve low pressure turbo (LPT), 145 PS (107 kW; 143 hp) at 5600 rpm and 202 N⋅m (149 lb⋅ft)

900 turbo – B202 16-valve turbo, 160 (118 kW) at 5500 rpm and 255 N⋅m (188 lb⋅ft) //175 HP, 185 HP special versions//

The factory data can be improved (without changing boost pressure), as shown in the following charts from the dynamometer – without apc and with apc prepared by 900classic. Note that the curves are smoother after the modification, and mamximum torque and power are obtained at lower rpm, improving road performance
