What engines fit in a Fiero?

V6-204 CID, 3.4L, Pushrod Engine The 3.4 Liter 60 degree pushrod engine is one of the most logical choices for replacing the old, worn out, 2.8 Fiero engine. This engine is available as a like-new, factory rebuild or factory crate engine.

How much horsepower does a 87 Fiero have?

Although the base engine was GM’s Iron Duke 2.5-liter four-cylinder, the Fiero GT used a more powerful fuel-injected 2.8-liter V-6 rated at 140-horsepower – that might not seem like a lot, but this car was smaller and lighter than the 240-horsepower Corvette from 1987.

Why did Fieros catch fire?

When the engine ran low on oil, connecting rods could blast through the side of the engine, spraying hot oil on the exhaust manifold, often resulting in a fire. Roughly 20 percent of 1984 Fieros experienced engine bay fires, Autoweek reported in March 1988.

Why do Fieros catch on fire?

The Pontiac Fiero Used To Catch On Fire According to an article from the Los Angeles Times about the investigation of the Pontiac Fiero engine fires, the fires were caused by oil leaking into the engine and combusting as the engine heated up.

Why is the Fiero bad?

Poor reliability and performance, expensive maintenance, and an awfully heavy and underpowered engine did not help the case either. Motor One calls it the worst sports car. Anyways, the number of reported fires was so huge that the cars had to be recalled. One Fiero exploded out of every 508 cars sold.

What’s the difference between a Fiero 3800 and 3800 TPI?

In 1992, the supercharged version appeared using a M62 blower. As far as I can tell, there was no difference between the Series I SC vin 1 engines and the 3800 TPI vin L engines except the connecting rods and possibly pistons. The cranks and heads are all the same, (except for balancing differences) according to my info.

Where does the exhaust mount on a Fiero 3800?

Rest of exhaust mounts up in pretty much the stock location but it is very close to the truck’s heat shield allowing the top of the muffler to just clear the exhaust dump from the 3800’s manifold. Some of my 3800 conversions were done in original 4-cyl, pre-88 cars and the stock 4cyl upper hose fit with slight modification to the hose.

Is the 92 PCM compatible with the Fiero 3800?

There was also an issue with the VSS sensor. The 92 PCM wants to see an analog, 30 Pulse Per Revolution (~24,000ppm) input that most 4T60-E’s can supply. The stock Fiero VSS outputs a digital, 4,000 pulses per mile signal that will not work here.

What’s the difference between the 3800 and 3800 Series 2 engines?

The heads are altogether different than the series I and also flow much better. Because of the shorter deck height, connecting rods are also shorter too, giving the 3800 Series II engine less reciprocating mass at the expense of rod-to-stroke ratio. The N/A 3800 II engine does not share the same rods or pistons with the SC version.
