Use the RTV Black Liquid Gasket and put a thin bead on both the Supercharger and the Moddbox Intake Manifold. Press the Moddbox Intake Manifold Assembly onto the hose prepared in a previous step.
Bolt the Moddbox Intake Manifold to the back of the Supercharger using the provided four M8x25 SHCS bolts. Use the RTV Black Liquid Gasket to seal the Moddbox Custom Washer in place as shown (the bolt located inside the Intake Manifold). Tighten the 2" stainless hose clamp around the bypass valve.
Note: The Moddbox Custom Washer must be reversed for the 94-95 Superchargers (orientation shown is for the 89-93 superchargers).
Use the RTV Black Liquid Gasket and place a bead around the Intake Manifold Top Flange. Place and bolt-up the Intake Manifold Cover as shown. This whole Supercharger Assembly will be used in the next steps.
Remove the rags or paper towels in your Engine Inlet Ports. Apply a thin bead of Black Liquid Gasket along the Plenum Base Plate. Caution: Be sure to apply gasket material around all the bolt holes (as illustrated in the photo below). The gasket material must be extended to the inside edge of the mating face as shown on the bottom-left of the photo below. Failure to do so can result in a leak in your Intake Manifold Assembly.
(Note: Engine rags/paper towels removed from engine ports prior to installing Plenum Top Plate)
Place the whole Supercharger Assembly on the Moddbox Plenum Bottom Plate. Align the holes and bolt it down using the twelve M8x30 hex bolts. Do not forget the bolt under the Supercharger Snout. Torque the bolts in a cross-pattern.
Locate the disconnected Fuel Vapor Return Line. Cut off the press fit connection and reconnect it to the remaining 3/8” barb on the ModdBox Intake Manifold.
Connect the fuel Vapor Return Line to the un-used Barb as illustrated.
Use the provided 1/4" Tee and connect the Brake Boost and Vac Lines to the 14" long 3/8" diameter hose connected to the Supercharger Assembly (prepared in an earlier step). Secure the Vac lines with the provided hose clamps.
Connect the Moddbox Flexible EGR Extension to your EGR valve.
Install the EGR Valve using the Moddbox EGR Spacer and the provided M8x40 SHCS bolts. Note: The provided spacer is anodized black (raw aluminium shown).
Install the Throttle Body.
Bend the Stainless Steel EGR Extension to suit. Secure it with the provided C-clamps as shown. Connect the EGR Extension to the stock EGR re-circulation line. Caution: The Stainless Steel EGR Extension is not designed to be twisted. Do not twist the EGR Extension when tightening the threads or damage to the extension may occur.
Use a knife and carefully cut your Stock Rubber Intake Pipe along the center of the ribs as shown. Be sure to count the ribs and confirm the exact location for cutting.
Use your knife and carefully carve out the ribs to allow for a stainless hose clamp.
Install the Moddbox Intake Pipes using the Stock Rubber Intake pieces and the provided hose clamps.
Install the 5/8" diameter hose to the Crankcase vents as shown. Use the provided Tee and stainless steel hose clamps to securely fasten them together. You may opt to cut off the stock crankcase vent connection ends and reuse them if a stock-looking snap fitting is preferred.
Use the provided wire and butt crimps to extend your Electronic Throttle, TPS, and EGR plugs. Use the loom and remaining plastic strap to secure and clean-up the wiring once completed. Plug the wires back into the TPS and EGR.
Slack your Belt Tensioner using a 3/8” Box Wrench or Belt Removal Tool. Remove the Stock belt and replace it with the ModdBox 6PK Belt as illustrated below.
Optional. Affix the "Supercharged" emblems where appropriate.
Plug in the MAF sensor, reconnect the disconnected Ignition wires, top up the coolant level, and reconnect the battery. You must allow the liquid gasket material to fully cure at room temperature or as per the manufacturer's recommendations. Failure to provide the necessary curing time may lead to vacuum leaks.
