Installation Instructions

Also applicable for the 1990-94 Mazda Navajo and 1994 Mazda B4000

50 State Smog Legal, as per CARB EO #D-213-17

Congratulations on selecting the best performing and best backed automotive

supercharger available today... the VORTECH^®V-2^®Supercharger!

NOTE: This supercharger kit is designed to fit on Ford Explorer/Mazda Navajo vehicles. This kit, with the

addition of the Ranger Supplement assembly part number 4FD248-050, may be installed on 1990-1994 Ford

Ranger and 1994 Mazda B4000 vehicles.

Before beginning this installation, please read through this entire instruction booklet and the Street

Supercharger System Owner's Manual which includes the Limited Warranty Program and the Warranty

Registration form and return envelope.

Vortechsuperchargersystemsareperformanceimprovingdevices. Inmostcases, increasesintorqueof30-35%

and horsepower of 35-45% can be expected with the boost levels specified by Vortech Engineering. This product

is intended for use on healthy, well maintained engines. Installation on a worn-out or damaged engine is not

recommended and may result in failure of the engine as well as the supercharger.

Vortech Engineering is not responsible for engine damage.

Installation on new vehicles will not harm or adversely affect the break-in period so long as factory break-in

procedures are followed.

For best performance and continued durability, please take note of the following key points:

1. Use only premium grade fuel 92 octane or higher (R+M/2).

2. The engine must have stock compression ratio.

3. If the engine has been modified in any way, check with Vortech prior to using this product.

4. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost) until problem is

resolved.

5. Perform an oil and filter change upon completion of this installation and prior to test driving your vehicle.

Thereafter, always use a high grade SF rated engine oil or a high quality synthetic, and change the oil and

filter every 3,000 miles or less. Never attempt to extend the oil change interval beyond 3,000 miles,

regardless of oil manufacturer's claims, as potential damage to the supercharger may result.

6. Before beginning installation, replace all spark plugs that are older than 1 year or 10,000 miles with original

heat range plugs as specified by the manufacturer and reset timing to factory specifications (follow the

procedures indicated within the factory repair manual and/or as indicated on the factory underhood

emissions tag). Do not use platinum spark plugs unless they are original equipment. Change spark

plugs every 15,000 miles and spark plug wires every 50,000 miles or earlier.

11. FINAL REASSEMBLY & CHECK

A. Reconnect the battery.

B. Check all fittings, nuts, bolts and clamps for

tightness. Pay particular attention to oil and fuel

lines around moving parts, sharp edges and

exhaust system parts. Make sure all wires and

lines are properly secured with clamps or tie

wraps.

C. Check all fluid levels, making sure that your
