For sale is my stage 1 c38 rotrex supercharger kit from AA. The kit has about 15k miles on it. I had this set up on my obd1 s52 swapped e30. I made 315whp @ 9psi. You will get 2 tunes with this kit. First tune was for s50 cams, 540HFM and 30lb injector with the rotrex c38 on 91 octane. The second tune is for schrick cams, 540HFM, and 30lb injectors with the rotrex c38 on 91 octane. The kit is 90% complete. I'm selling the kit to use the money on house projects. I am asking $2300 OBO. Contact me for more information. Buyer pays for shipping.
What you will need to complete the install:
1. Bosch 3.5'' maf (800 part number), I've seen them on bimmerforums for less than a $100
2. New belt (old one was cracked: $65 from AA)
3. Air filter
4. Rotrex traction fluid (I have about a 1/3 of the bottle left, $99 online)
5. A few Hose Clamps
6. One Alternator bolt (i reused mine, you don't necessarily need a new bolt I shaved mine down to clear the supercharger belt)
This kit can be used for obd1 and obd2 cars. My kit is already setup for obd1 and all you would have to do is install everything and you are good to go. For obd2 cars you will have to install the scaler (which will be included in the kit) and have your DME sent to AA to have it reflashed for your setup. You can also have TRM flash your dme. I am not certain on the cost for the reflash but my tune cost me $750 to give you an idea.
