Pontiac Fiero

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

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

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.

First the engin idles high in the begining till it get to a some what warm position. it is 25 yrs old. then it should idle around 1000 or a little lower. There could be an adjustment made to the timing to advance the problem. I am in the process of doing this myself tomorrow I just had to put in a coolant sensor and that made my engein idle really low and die out. Now that this day has come I had decided to spray carb cleaner into and round the carb. while reavin engine by hand. WOW WHAT A FN different this has solved th problem. mus rember yhis is old car and lots of dirt and mechinizams.... let me say tho this still a progressing process. I must now find out Y the fan now only come on when AC MAX is on. jus started after i put n coolant temp sensor. (but that did clear up dying of engine. So now what? HELP ME

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.

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

Inside the alternator

Engine coolant fluid? Engine oil? Transmission oil? Brake fluid? Power steering fluid?

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.

i paid 500+ tax

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.

4.5 quarts for a 4 cylinder.

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)

my 88 fiero had two valves stuck, one on cyl 2 and one on cyl 3.. if it would start it was on one or two cyl... or he crank senor might be bad

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

if its slipping it may be going out or just needs a full trany service. you can get all the stuff at napa

If the Fiero has a munual transmission there is a 13mm plug in the side of the transmission on the rear driverside about three quarters of the way up twards the trunk. Theres also a plug on the transmission, on the passenger sidetwards the bottom. That's also a 13mm that is a drain plug. only pull this one if your flushing the transmission. Otherwise pull the top plug and full with a 5 30 weight oil it will say on the plug what to use. Ak47pk47@yahoo.com or hit me up on my space at keffer paul@ yahoo.com

I have a 88 fiero with a 3800 and a 4l60 e overdrive supercharged out of a 94 olds bought it from a guy, very fast dyno 310 hp to the ground modified injectors , super charged forged pistons .030" over balanced , heads ported , forged rods . a few bugs I am working out i believe this would be a series 11 churchdad101@hotmail.com

Your 1984 2.5 four should never ever need an adjustment.

But if you have noisy valves, remove air cleaner and valve cover.

Check valve lift (it is likely if you have noisy valves the camshaft has failed)

If all checks good, Rotate engine until each valve is on the base circle of the cam, adjust valve until there is no lash or slop in the rocker and tighten an additional 1/2 turn.

Fieros came with a 2.5 four or a 2.8 V6. None were made with a 3.1

Whatever your wallet can make go in there. Personally? I've replaced the stock 2.5, done a clutch on a 2.8, and even welded in a 500 cube big block out of a 72 eldorado in the back of a fiero. Granted, I had to rip out the sub-frame, trunk, and a few other things, and (beer, pizza, a stupid side bet, and too much cash aside) it really wasnt done quite right because it was more of a joke than anything else, but it did fit...

Side note, if your putting in a 500, be sure to add some reinforcement to the floor of the fiero, as well as the firewall, otherwise you'll just end up ripping the back end of the car off from the torque, and having to tow home two halves.

But it was pretty cool...

Mine is currently getting a 3800 supercharged out of a Grand Prix GTP

I have done 3 Small block chev conversions

And there are many of the new overhead cam GM motor out there

But my favorite is the Cadillac Northstar

proly should just junk it

At what RPM and load?

If at idle it is running way lean and has probably got a cracked EGR valve to manifold tube.

At higher RPM and load this is normal.
