i no this has been covered before but, I just got done rebuilding my itr. It is mainly stock besides that i put oversized pr3 pistons in it with a 2-layer headgasket. im guessing the comp. is going to be around 11:3 to 11:5. Well the real question is what plugs should i run and what to gap the at. thanks

 

NGK BKR7e11's this is what i have for my 2.0 setup (12.5:1cp) This is what my tuner recommends. Keeps it in stock as well in his stock.
