about a month ago my bro gave me his 300zx tt 1990, its was missfiring. i replaced all plugs and swapped coil packs, cyl #1 is missing, i did a compression test, 130 others were 140-145. i then flushed the oil and smelled gas mixed with oil. i think the injector is not closing and dumping fuel. he bored the stock 370cc to 555cc. do i buy the nismo 555 (old style) or swithed to the 615cc(new) ? ived heard the older were bad? is it true
