hey smaay I don't have a cel but I have a corolla that had a 1.8 in her but now I have it rebuilt or the works in it . I have the big bore kit and sp rods and crank in mine and port and polished. The head has bigger valves with 3 angle grind on them and stronger springs. But the problem is all I can get out of it is 6900 rpm's out of it. How can I get 8k rpms? my ecu has been tweeked by some friends at the dealer here in town.
