Would anyone believe then, the A series engine would be so durable and yeild power figures as they do Today? Here's how it's done. '''Brief overview of the Engine''' A BMW K1100 (motorcycle) 16v Twin cam cylinder head engineered onto Rover A+ Series engine and transmission. *Choce of OEM camshaft sets. GT, LT or RS. I have installed the low duration GT inlet with the slightly longer duration LT exhaust. *Cam timing set for 115 inlet and 110 exhaust. *Engine is a 1996 onwards 1275cc MPi block over bored +0.5mm. *Accralite 18cc dish forged pistons, at 1293cc and compression 8.5:1. **Now increased to 9.0:1 *Standard crankshaft, Nitrided. *Mitsubishi TD04HL-15T turbocharger from a SAAB 93/95. *Transmission is an uprated straight cut gearset with a Quaife ATB diff. **Transmission now replaced with up rated helical gear set (oh the silence is bliss) *Similar combination already dyno'd at 268hp on 20Psi boost.
