In short it would seem Porsche was involved in the intake and exhaust manifolds on certain Volvo's.

During the development years of the 850 model, it took Volvo engineers some 10 years to introduce the first ever FWD car: the 850.
Volvo wanted more than 4 cylinders but less than 6 cylinders, so Porsche engineers helped them with B52xx (B5254 etc.) engine development in the early 1990s.

This could explain how Volvo extracted more power out of their N/A I5 than GM could out of the 60 degree 3.1L V6 they shoehorned into a goe-zillion cars (it falls a measly 2hp short of the power of the 3.4L 60deg V6 too)
