What was the first engine swap for a Fiero 3800?
The very first 3800 swap I did used a ’92 Series I 3800 SC from a wrecked Park Avenue Ultra. I also kept the PCM and wiring as well as PASS-KEY module and ignition key resistor value for future use. For this first swap I did not yet have the ability to reprogram the stock chip.
Is the Buick 3.8 the same as the Fiero 3800?
It is virtually the same as the FWD Buick 3.8 with the exception of having the oil pump located in the timing cover and used DIS instead of a distributor. In 1992, the supercharged version appeared using a M62 blower.
Where can I get a Walbro pump for my Fieros?
The Walbro 307 has been superseded by the Walbro F20000169 pump. You can purchase this pump and a univeral 87-92 GM install kit from Precision Turbo and Engine for about $130.00. With this kit, this pump is a direct drop-in replacement for 87-88 Fieros. Earlier Fieros will require some in-tank rewiring as shown below.
How big should the rear cradle be on a Fiero 3800?
You can give yourself some more room and alternator-to-hood clearance if you space the rear cradle down about 1/2-3/4″. I sawed a hockey puck in half and then drilled holes in them and simply inserted it between the existing cradle mount and the body.
