I'm on the hunt for a 240T and am interested in what increased the HP between the '83 and '85 model years for the B21FT. I do know that the '85 had an intercooler...but would this add 35 more horses? What else was done to the '85 engine to give it so much more power? (I got my HP info from Volvoworld.com)

Thanks,
Bean

I have a 245GLTi production 9/84 and Mr Haire is correct : Mine is all stock with the exception of the turbo came from a 740T ..This car moves with ease. Happy New Year..

The intercooler actually appeared on the rare "flathood" 242T special addition in late late '83. Now that intercooled car has the small clutch and flat flywheel of all 81-84 turbos (84 applies to the early 84 non-intercooled ones) aas I found out this last week. In 84 1/2 the 242 and 244 turbos appeared with ICs and the big clutch and stepped flywheel. As for hp, the intercooler and higher boost it allows, explains the increase in power. The '85 owners manual does list a higher compression ratio for the 85 244Ti but most people think that is a typographical error. However, I am a firm believer that the 85 (maybe 84 1/2 cars) are the fastest of the lot equalling a V8 muscle car in power. If you have not driven a properly running 240Ti with a good turbo unit, you will be astonished at the rocket kick they provide at 3000 - 5000 rpms. I have yet to up the boost on the flathood ('83), but so far it does not seem to equal my '85 in its turbo prime.
