Hi,
has anybody experience with "performance" cylinder heads, especially with the ones from
As I have the rebuild the head of my petrol 2,25 IIa this winter I am thinking about buying a performance head. They claim a power and torque increase *without* any further modifications. As a regular engine tuner (motorcycles, Mini, etc.) I am basically not a newbie to engine tuning, but I don´t know anything about performance enhancements on the old 2,25 lump.
As I drive my 109 through the northern sahara I would appreciate a little bit more torque over the whole rev-band and a little top end power plus. The head they sell has 1:8 compression so this would be no problem for my africa journeys.
I basically don´t want to alter further enginge parts because I would like to conserve the reliability and repaireability of my old friend, so a head which alone brings a little bit more power would be nice.
