Are there ways of increasing the horsepower on 1994 2.3 ford ranger?

Answer 1

3 simple things that can be done to HELP power: 1. Modify the Factory air Intake and Filter Box. Alter it to accept MORE AIR. A 3" PVC inlet into the box from front of vehicle will do the trick. Also, remove the restrictive muffler inside the air tube going from the filter box to the throttle body. 2. Clean the Throttle body very well (carb cleaner ...both sides) and also the upper air intake. SOAK IT WITH CLEANER. After treatment let it sit for about 30 minutes. This allows some of the cleaner to work on the lower intake manifold as well. Carbon, crud and gunk build-up will SLOW and restrict the air flow to the engine down from the throttle body to the head...causing a loss in power. The engine will require a few attempts to restart later and then have to burn off all the crud broken loose in the intake with the cleaner. Have patience though...should run like a top when done. 3. Decarbonize this older engine! Put a vacuum line on the vacuum tree (where at least one pipe is capped). While engine is idling let it inhale SEA FOAM or even COLD water! A 50/50 mix of brake fluid and water chilled to refrigerator temp will help this condition also. Be careful with the water however as HYDROLOCK can occur. The KEY is to let the engine SIP the solution while it is running. Run the engine speed up(at the throttle body) to about 1200RPM periodically while doing this. Don't let it stall. It can stall with cleaner but NOT with water. Engine condition dictates how much is needed. A few pints to a liter or two should do it. Water turns to STEAM inside a warmed-up engine and REMOVES a lot of scaly carbon off the piston tops and cylinder head and exhaust valves. The Oxygen sensors should be ok. This procedure too will bring back some lost power to the 2.3L. Be very conservative with the water method however.
