Glossary of Saab Terms
« on: 27 June 2011, 12:02:32 AM »
Engines:

Either carburetted, fuel-injected or turbocharged.  Turbo engines come in three broad flavours:

LPT – Low Pressure Turbo.  Mild turbocharging, designed to give a broad spread of torque with minimal lag and smooth power delivery.  Boost pressure of up to 0.45bar / 6.5psi
FPT – Full Pressure Turbo.  More serious turbocharging, upping bhp and torque significantly.  Generally using a larger turbocharger than LPT models.  Boost pressure of 0.8bar / 11.5psi and above
HOT – High Output Turbo.  Serious turbocharging for performance (Aero and Viggen) models.
N/A, n/a - normally aspirated.  i.e a non-turbocharged engine.

As a general rule, engine designations follow the format ‘Bxyz’ followed by a letter.  x and y denote engine capacity.  z was initially used to refer to the number of auxiliary shafts, but on later engines is more of an indication of the evolution of the engine.  The final letter denotes the type of induction used.  So:

B201 – 2.0litre (1985cc), 4-cylinder with sohc (99, 90, C900)
B202 - 2.0litre, 4-cylinder engine with dohc (C900, early 9000, early GM900?)
B204 - 2.0litre, 4-cylinder engine with dohc and twin balancer shafts (9000, GM900, 9-3)
B234 - 2.3litre, 4-cylinder engine with dohc and twin balancer shafts (9000, GM900, 9-3)
B205 - 2.0litre, 4-cylinder engine with dohc and twin balancer shafts (9-5)
B235 - 2.3litre, 4-cylinder engine with dohc and twin balancer shafts (9-5, 9-3 Viggen only)

Suffix letters denote type of induction, forced or otherwise.  As a rough guide:

Thanks for this, most appreciated.  Would it be possible to add the model 'code' and what it ment in terms of aspiration - normal / high or low pressure turbo and any other relevant information such as its trim ie sporty, comfort etc.  I'm thinking of the letters - GL, GLE, S, Viggen, CSE etc.  I know I don't probably fully appreciate the level of knowledge required, however I'm sure its ratteling around inside all the mods here :)

- and I couldn't see CEL for 'check engine light', which is quite a common usage (though I don't know how formal).

[mod edit] Done!

Pedant mode engaged Will

B201 was in the 900 from M81 onwards, M79 and M80 had B20.  In the 99 the B201 appeared for M82, while the M81 had the B20

The B20 was better known as the B-seried and the B201 was known as the H-series.

99LE was available with B20 only, there were 99 GLi in certain markets, up to M82 they were B20, and M82 on were B201

B212 was a 16 valver, 140PS

The B284 didn't come with the 230PS option, which I think was availble for the Vectra Elite...AFAIK the 2.8V6 came first as a 250PS then a choice of 255PS (FWD) or 280PS (XWD/Turbo X). NG 9-5 Turbo 6 is 300 PS

Sorry :-[

I must have another look at this, but not until I get back to my desktop.

Pedantry is what this page is all about!! :)
