The evap purge solenoid goes inline between a constant vacuum source (between the supercharger and the throttle body) and the evap canister. The brake booster vacuum also goes on vacuum side.

The fuel pressure regulator needs to be on the boost side (LIM) of the supercharger, along with the MAP.

I might be stating this a second time but make sure both your CTS and your oil pressure sender connectors are 3 wire connectors. Middle pin of each goes to the gauge. Also if either the CTS or the oil pressure sending unit are not 3 pin devices they will have to be replaced.

I have a three wire CTS. I have a two wire oil pressure switch on the oil filter adapter. What would be the P/N of the correct one?

Look up a replacement for an 88 Fiero 2.8 and that's it.

I have the old 2.8 that came out of the car, 86GT. Ill just use that one. Thanks!

Edit; I checked the P/N 86 vs 88, they are different, I will look up the specs to see if it will work. They are both 3 pin. The thread sizes are all the same for all three engines. Yup, Rock Auto shows the 86 one will work on the 88 engine.

88 fiero
Thread Size 1/4-18 NPTF Dryseal
Switch opens 2-7 PSI
80 PSI - 60-96 Ohms
40 PSI - 48-70 Ohms
8 PSI - 20-35 Ohms
Less than 2 PSI - 5 Ohms max

fits
BUICK (1987 - 1995)
CADILLAC (1998 - 2000)
CHEVROLET (1988 - 2001)
GMC (1988 - 2001)
ISUZU (1996 - 1998)
OLDSMOBILE (1987 - 1999)
PONTIAC (1987 - 1995)

Re-edit; The 86 one is too big for the low mount alternator but it will clear the axle. I guess i need to buy one, LKQ here I come.

Found one at LKQ from an 88 4 cyl fiero. $12.00 with a passenger side mirror glass only and 2 windshield washer squirters.

What is up with this mystery connector (small round spliced into tranny connector with a gray wire? It does go to the PCM.
phonedawgz JUL 11, 02:06 AM
It looks like the AC Pressure Sensor. If so it connects gray to +5v, black to sensor ground and the red/black wire goes to the PCM.

The boost bypass valve usually gets deleted. I see yours is still on.

Many builders decide to locate the MAP and EVAP Purge valves on the transmission instead on top of the valve cover to keep the top of the engine cleaner. Where you locate them is personal choice of course.

What are driveability issues with deleting the BBV? economy vs. performance.

Also my car is a 2.8 stick shift . There's an 88 tech 4 auto at the local pick apart. What parts will I need to get together. I heard my accelerator cable wont work. The four cylinder one will?

No driveability issue in deleting the BBV...Some say they have gottne better MPG with it still attached with vaccuum only..I have deleted it in all my swaps but the one that went to Cali...The V-6 cable works fine but the 4 banger is a direct fit...Buy it to re-sell as you can get $50 for it to someone looking for one as they are getting hard to come by...So you already have the DRV auto axle...if not you will need it......
