you can not put a regular 3800 intake in place of the 3800 super charged engine,the compression ratio is lower than the regular 3800 engine.......!
SOURCE: replace supercharger serpentine belt 96 riviera
HI,FIRST OFF THIS IS A SIMPLE FIX,IF YA JUST DON'T LET THE THING SCARE YA.THERE IS A DIAGRAM ON THE ENGINGE SIDE OF THE HOOD ALSO TO HELP YA REMEMBER I ALWAYS MAKE MY OWN ,HOPEFULY YOUR NOT AS THICK HEADED AS I AM.HEHEHE!FIND THE BELT TENSIONER IT WILL BE SHINY.WITH THE HAND PUSH ON IT SHOULD MOVE UP AND DOWN JUST A LITTLE.YOU SHOULD SEE A BOLT HEAD IN THE CENTER OF THE WEEL/PULLY .WITH THE CORRECT SIZE WRENCH OR SCOKET PUSH DOWN ON TOOL THE BELT WILL LOOSEN UP ENOUGH TO REMOVE.REINSTALL NEW BELT MAKING SURE THE BELT IS ON ALL PULLIES AND THEN REMOVE PRESSURE FROM WRENCH THE BELT SHOULD BE ON ALL PULLIES AND TIGHT START THE ENGINE AND CHECK THAT THE BELT IS TURNING ALL YOUR PULLIES AND THEN TURN OFF ENGINE CHECK YOUR GREAT WORK YOU SHOULD HAVE ALL PULLIES TOUCHING THE BELT AND THE BELT TENSIONER KEEPS THE BELT TIGHT ,NO ADJUSTMENT NEEDED.I HOPE THIS WORKED FOR YA ,IF NOT REDO THE JOB YA WILL QUICKLY SEE WHAT YA NEED TO DO THE NEXT TIME IT'S JUST THAT EASY .

Sorry for the delayed response.
CLICK on the following LINK. It has the Belt Diagrams including the Supercharger you will need.
If you would: Before Clicking: Let me know if this helped you, or if you have any additional information or questions. Feel Free to contact me at FixYa.com!
Again my apologies...
Thanks.

SOURCE: can i still drive a 95 buick riviera with a bad
if your supercharger sounds like tumbling rocks, it is the plastic coupler between the nose cone and the charger body; take off your serpentine belt; chances are the pulley has some play in it but it turns freely; the replacement coupler is a cheap fix; what gets a lil pricey is the labor to replace it... the buick has an alternator bracket that has to come off before you can take the nose off of the supercharger... dont forget to drain the oil from the nose cone with a spray bottle nozzle

Ignition voltage is present on circuit 839.

The CKP signal at PCM is NOT detected.
DTC P1599 is a type D DTC
The PCM has the ability to set a diagnostic trouble code (DTC) if the engine stalls when the ignition has NOT been turned OFF. This DTC may aid in intermittent diagnosis of a customer complaint of intermittent engine stall. The scan tool Failure Record information can be duplicated under the same stall conditions in an attempt to reproduce the occurrence. Since DTC P1599 is a type D DTC, the PCM will not command the MIL or SERVICE telltale ON. This DTC can set due to driver error. For example, a vehicle equipped with a manual transaxle in which the clutch was released too quickly causing the engine to stall.
DTC P1640 (PCM Output Circuit)
The PCM contains an output driver module (ODM) which controls 7 circuits: A/C relay, air pump relay, EVAP purge solenoid, EVAP vent solenoid, fan control 1, fan control 2, and TCC solenoid. The ODM controls each of these circuits independently by controlling the circuit ground. The ODM monitors the voltage level at each of the 6 circuits into the PCM when the device is being commanded ON or OFF. When the device is commanded OFF, the circuit is not grounded, the voltage level at the PCM should be high (ignition voltage). When the device is commanded ON, the circuit is grounded, the voltage level at the PCM should be low. Each of the 7 drivers in the ODM contains a feedback circuit used to determine if a particular circuit failed, which can be read on the scan tool. DTC P1640 sets when any one of the 7 feedback voltages is low when that device is turned OFF or when any one of the 7 feedback voltages is high when that device is turned ON when the engine is running.
Sounds to me like you have a short on one of these circuits !
To locate an intermittent problem, use the scan tool to command each of the 7 solenoids tied to the ODM circuit ON and OFF independently while monitoring:
A/C RELAY CKT OPEN SHORT TO GND
A/C RELAY CKT SHORT TO VOLTS
OR
AIR PUMP REL. CKT OPEN SHORT TO GND
AIR PUMP REL. CKT SHORT TO VOLTS
OR
EVAP PURGE CKT OPEN SHORT TO GND
EVAP PURGE CKT SHORT TO VOLTS
OR
EVAP VENT CKT OPEN SHORT TO GND
EVAP VENT CKT SHORT TO VOLTS
OR
FC 1 RELAY CKT OPEN SHORT TO GND
FC 1 RELAY CKT SHORT TO VOLTS
OR
FC 2 RELAY CKT OPEN SHORT TO GND
FC 2 RELAY CKT SHORT TO VOLTS
OR
TCC DUTY CYCLE OPEN SHORT TO GND
TCC DUTY CYCLE SHORT TO VOLTS
If IGN 3 fuse is open, A/C RELAY CKT OPEN SHORT TO GND, EVAP VENT CKT OPEN SHORT TO GND, and EVAP PURGE CKT OPEN SHORT TO GND parameters on the scan tool will read YES.
Do you have a DVOM - digital volt ohm meter ? You need to check each wire in the above circuits for a short to ground or B+ !

Fault detected for 5 seconds for DTC P1651. Fault detected for 20 seconds for DTC P1650.
Important: The QDM circuit is continuously checked when the engine is running.
