How much is a engine cradle for a Pontiac fiero?

This not so rare but difficult to find part will have a cost set by the seller. Because these change hands so rarely you will just have to make a deal.

No but unless you have a professional trans shop with tools it is easier, and most trans shops drop the engine due to the hassle doing it the other way takes

Can you use a fiero gt speedometer in a fiero se?

User Avatar

Asked by Wiki User

It depends on what Fiero SE you own. There are two types. The earlier SE models, '84-'86, used a 85 mph speedometer for the four cylinder engine. It would not be until the '87 V6 model that the SE cars received the 120 mph "GT", as it's called, speedometer assembly.

If you already have a 120 mph speedometer in your Fiero SE, it will work just fine. If it's the 85 mph speedometer, it will not, and would read incorrectly until you perform the necessary modifications to make it act like a 120 mph speedometer should.

How much horsepower does a Fiero SE have?

Asked by Wiki User

It depends what engine it is a V-6 has 130HP until 1987 they had 140HP, the l-4 had 110HP

i 4 had 92-98 hp depending on year v6 had 140 hp all years i believe in 1987 they lowered the rpm's so it looked like it had less so that it would fit in a cheaper car insurance bracket

No, Fiero seats are pretty special to fit in where they are.

I recomend you repair your old with parts from the fiero store.

What is the strongest transmission you can put in an 88 Pontiac fiero?

User Avatar

Asked by Wiki User

The THM125 automatic is a good solid piece and can with proper care be used with the V8 engine swap

The original 5 speed manual is similarly strong.

As a refit the 4t60 and 4t60E are good choices for increased fuel economy and strength but require considerable modification to install.

How do change a starter for 84 Pontiac fiero?

User Avatar

Asked by Wiki User

Disconect battery.

Jack up car and Make Safe to work under, You need to work on the front end of the engine from underneath.

Un bolt the starter, Depending on what plant built your engine 9/16 or 15mm bolt heads. Lower it gently to hang on the wires.

Undo the wires, and reverse the process to install the new one.

Depending on the cars options it may be easier to undo the wires before lowering the starter.

What other cars have the same wheel bolt pattern as an 88 fiero?

User Avatar

Asked by Wiki User

All Fieros have the same 5 X 100mm Bolt patern

Many Front drive GM into the mid 1990s use this pattern

Many european cars use this pattern, Notably BMW

Many SUbarus use the same pattern and almost identical offset. I have a set of aftermarket 17" Wheels off a Subaru on my Fiero

What v6 will fit in a fiero?

User Avatar

Asked by Wiki User

How much modifying do you want to do?

  • 2.8-3.1-3.4 engines will fit no problem. The roller cam 3.4 requires the use of the 2.8 cylinder heads and replacement pistons and custom length push rods. All others require changing intakes and front accessories.
  • 3.8 and 3.8 super charged require custom mounts, available on line, custom exhaust available on line, and custom machined flywheel from a rear drive Camaro available on line
  • 4.3 Requires a V8 adaptor kit as it has the V8 bell housing pattern. Custom mounts and exhaust. This is not a popular swap as requires considerable work for no advantage over the 3.8.

Will the transmission from an 84 fiero fit a 87 fiero?

User Avatar

Asked by Wiki User

Physically, yes. GM's drivetrain are highly swapable. But there can be lots of differences. I'm assuming you are pulling "x" tranny out of an 84 to put in a 87 that had "x" tranny. Not pulling an "x" tranny out of an 84 to put in an 87 that had a "y" tranny.

The devil's in the details. Flywheels might not be the same. Most auto part places have the info and will glad to help.

What if there is no key hole?

User Avatar

Asked by Wiki User

Then it doesn't lock.

By trunk are you referring to the engine compartment or the front of the car where the spare tire is located? There is no key to open the front (trunk) compartment. This is done using a lever located under the dash next to the drivers door. The notchback or engine compartment has a key lock. Some models have a button on upper right of the gauges.

How much oil is put in fiero?

User Avatar

Asked by Wiki User

4.5 quarts for a 4 cylinder.

Will a 4.3 work in a fiero?

User Avatar

Asked by Wiki User

Realistically, any engine can be used in a Fiero... All you need is time and money.

It'd probably be a lot easier to do a Caddy 4.9 V8 swap - you can get the parts from V8 Archie through his website, or just take the car to him and have him do it (more expensive, though, it's professionally done)

What would cause your 1986 Pontiac Fiero 2.5 to jerk driving down the road like it is missing but it idles fine?

User Avatar

Asked by Silencer

If you have an automatic transmission, it is equiped with a "lock-up" torque converter. In normal operation, when you reach about 28-30 mph, the converter goes into lock up. The engine RPM will drop about 200 RPM if you maintain speed above 30 mph. But then a slight change in speed will cause the converter to unlock. Many mechanics solved the problem by disconnecting it. The trade off was a little less fuel milage, but the customer was happy. To test this out, drive at about 35 mph. While your foot is still on the gas touch the brake slightly with your left foot. you should feel the converter come out of lock up.

bad spark plug wires recommend you spray water and listen or if you do it at night you will see the plug wires break down the car will start missing when you spray them down
