dohc d16? what? at least I didnt see vtech "oh my, just looked up in the adverstisement section and there it is VTech Telephones, good for a late night laugh" Did some really really put a d16 into your teg? My advice: I am guessing this is a sohc motor your thinking of boosting, and building the motor is not cheap in any ***** aspect at all. to build a d series "rings, rods, pistons, the works ec ec. and getting it done right is going to cost a lot of money. say 2k if not more. It is not worth it unless you actually do have the funds. Get a fresher motor, slap on a thicker headgasket, get the kit you want within reason and use hondata, greddy e-manage or whatever you want and get it tuned right. More power in these cars does not always mean more fun.
