I've been thinking of a lot of crazy ideas to my car. One of em is swapping the cylinder head of the GA16DE to my GA16i. Ga16i is 12 valve, single cam 90 HP and no aftermarket support while the Ga16de is multi port injection, 16 valves, I can get CAI, Header, cams and upgraded ECU. I think it will be easier to swap the head(like the Honda Boys)rather than swapping the whole engine, tranny and other things. Do you guys think it is possible? I am only considering these options if it is possible. If cant be done, I like to get a SR20DE or even a GA16DE just to improve the power department. BTW I have Nissan Pulsar 89 with GA16i basically a B12 just with different shell. Later...
