Yes, at a loss of it elsewhere. Don't even think about remapping ignition timing without some sort of aftermarket ECU... I suppose if anybody wanted to get a bit fancy, I can see a set of quads from a SR20 hanging off the front of the head quite nicely... I have been researching this ;) and from what I have been able to gather, and from discussing with a friend, a set from a 20v 4A would be should be easier, but then again he dont know 2ZZ, do you honestly beleive SR20 would be better for the 2ZZ?
