Hi all I have just brought a saab 93 convertible turbo SE 1999 150bhp red top. Could anyone please tell me if this is a b204 engine. Also how tunable are these engine and aslo what is the difference between the more powerful 175bhp/200bhp models. Thanks in advance.

If it is red coil pack then yes it's a b204, the difference between this and the 175hp one is it has no apc valve so only runs base boost, 175 hp has apc valve and a different ecu map. Difference between both the b204's and the b204r (205hp) is ecu map and intercooler is cross flow on 204r as opposed to a twin pass (both inlet and outlet on same side) on the other 2.
Get an apc valve on and a stage 1 map, then you will see about 220hp with no other mods except for a good service.
as with most turbo engines, VERY tuneable. Forged bottom ends as standard. 270hp is very cheap and easy to achieve on standard engine with 3" down pipe and decat.
