yes its possible! you would have a larger cam and larger valves. its not really worth the work though, you should replace the whole motor(easy swap with the 2.0. that .5 ltr displacement does a lot! if you do the head swap, make sure you use the 2.0 ltr head gasket though. -
Thanks man, nah i am not planning to change the head, i was thinking about it, planning to transplant the 2.5l motor sometime soon, need to get some cash first.2.2 million E30s were made during the car's ten year life span.
