put in a sohc w/o vtec in my 99 hatch dx but having some trouble. cant get my car to rev up past 2000rpm's other wise it will stall. also have leaky oil pan and need a new seal but dont know which one to buy because year of car and mdl are unknown. also i am trying to use the intake mani that came on the zc. could this cause problems? dont wanna use the stock dx mani. i know a y8 intake mani will fit, but do to lack of funds im kinda stuck.
