L36 / L67 3800 Delrin Engine-Side Motor Mounts
This motor mount set includes (2) Delrin mounts for the engine side of the "dogbone" brackets that act as upper, engine-side motor mounts.
In stock form, there are round rubber bushings on the end that attaches to the engine, as shown in the picture below. These stock mounts allow quite a bit of movement, which is not the best for performance or for driving vibration.
These Delrin replacement bushings are each made of two pieces of Delrin, connected with a 6061 Aluminum tube to act as a wear bushing for the bolt.
These mounts will help quicken up shifts, along with the many options for the square mounts on the other end of the dogbones. The car will also be more responsive, as the motor does not lose as much torque into the mounts.
Once on the car, it looks stock, unless one knows what to look for. Installation takes about 30 minutes and can be done with a basic socket set and hammer.
L36 / L67 3800 Stainless Steel Intake Pipe
Cheetah's 3800 cold-air intake pipe fits in place of the stock intake box and tubing. The pipe is made from a single piece of 3.5" mandrel-bent 304 Stainless Steel. This pipe attaches to the stock rubber pipe on the throttle body, and puts the air filter in the fender area. This area gets the coolest air, and has become a favorite of many Grand Prix owners.
The large diameter of this pipe requires opening of the fender hole. This can be accomplished by bending back the metal sheet. The filter and pipe can be taken on and off of the car as a unit with the plastic splash guard off.
Any K&N style air filter can be used, as long as the flange ID is 3.5 - 4 inches, to properly tighten on the pipe. The filter that we recommend is the SB R0817. This is the filter shown in the pictures with the chrome cap.
The stock Air Temperature Sensor location can be maintained, but we recommend putting the sensor in the pipe near the filter. This will stop the sensor from getting heat-soaked from the engine, which will make the sensor read a higher temperature than actual temperature of the incoming air. This could possibly pull back the timing, which robs even more power. Cheetah recommends putting the sensor in the fender area of the pipe, about 1 inch downstream of the air filter.
The Grand Prix Store sells an extension for this sensor, but I just cut and wired my own extension.
Also shown to the left is the splash guard that I run on my Grand Prix. It is simply a piece of Aluminum bent at a 90 angle and has had two holes drilled into it. These holes allow it to be fit between the bumper and fender guard, and bolted in between as shown. This helps keep the filter clean and dry, and a guard is recommended for everyday driving.
This intake also removes much of the clutter on the driver side of the engine bay. The stock airbox is quite large, since it holds a large flat filter and the PCM.
The PCM can be held down with a GM part made for 2001 Chevrolet Blazers. This can be bought from any GM dealer as p/n 15995679.
