Hey i have a 91 civic with stock engine but with a AEM short ram intake.... is there anyway i can get the engine running faster without harming it? advance timing? idle mixture screw? anyone have any stats or numbers in which this can be done till without any harm? thanx

 

We need some HELP here, do we have a tech man in the house. John@M&H-Hashim's

 

gut out the car if you dont wanna harm the engine.. go with the normal proccess.. header, exhaust, throttle body,cam,ecu....etc...

 

My first purchase if I were you would be a DC header. The stock D series exhaust manifold is very restrictive, complete it by getting a full 2.25in cat-back exhaust system. A custom exhaust will be your best way to save some $$$ just make sure you get a straight through design muffler.
Advancing the ignition will only yield a small increace in power. Make sure to only advance it 2-3 degrees from stock. After you try that drive the car and make sure you don't hear any pinging. If you hear pinging you have 2 options to stop it. Back down the timing advance or run premium gas.
Don't touch the idle mixture screw because it will do NOTHING for performance.
What D-series engine do you have in your civic.
Let me know if you have any more questions???
