You spell like a 3 year old.

Are you sure you did the test right? Because if your compression is in the 90's your engine is ****ed.

You have to push the pedal down to the floor when you do it, also take out the ecu fuse so the dizzy isn't trying to make a spark while you are cranking. The numbers should be around 190-200 and within 10% of each other. If you are 14 years old there is no way you are going to be able handle a car with nitrous. Do you know what torque steer is?

wow, I don't think that your doing it right, check with a tech on how to do it on your car, sometimes it varies like on mine. Oh and don't add nitrous oxide to a stock block and head unless you feel like pulling your motor out a month later and replacing pistons you blew a hole through.

:eek:*Sighs*... You can run nitrous on a stock engine if you do it right.
