Yeah the coil is a bad idea, they are not gonna help. Actually it would probably do nothing at all. Honda ignition systems are very hot anyways.
The injectors are a waste of money, you aren't going to make over 190 wheel so you spent money just to say you had injectors on it.
Plus I don't think the 13.1:1 cr will be very becoming for a wheezing engine. P30 would have been the way to go. You are effectively making the engine less efficient by splitting the combustion in half with ctr's. The way to do it would be just flat top 10:1 pistons with a modified combustion chamber. So basically you should have bought some different pistons b/c you won't make a marginal increase in power from them, just problems.
