Wait, you lifted the body by the trunk latch? Lol, you better make dang sure its perfect before you try to shut the trunk. Been there, done that, I had to pop out the freeze plug and open the hole at the bottom of the trunk and reach up in there to unbolt the latch so I could get the trunk open. Best bet if it isnt, take the one off that guy in the background, I tried straightening it out, didnt work
Yes I pulled it up by the latch. About the second or third time it started to bend. I just bent it back, I might have even replaced it at one point. So many Fiero parts at the yard in Vegas I forgot what I have changed. Now I pull back the trunk carpet and use to holes allready there to lift by. When I did this swap it was my first engine swap that I did myself, Now I have done like 10 or so for the club in Vegas, not counting clutches etc...
Thanks for the great write up. I just bought a 3.4 from a 94 Camaro with 27000 miles.
One question, for an 87 GT could I/should I use the Fiero oil pan?
Thanks again, and a + for you.
I have an 87, I just used the 3.4L oil pan with IMPACT PERSUASION The motor mount hits the pan, so I hit the pan (with a hammer), now it all fits. Paint's still wet, thus the darker color
I didn't test fit the Fiero pan, only the 3.4 one. Nice score on getting an engine with only 27,000 miles on it. Mine, so I was told, had 50,000 on it. But mine was VERY clean when I took it apart.
Awesome thread! I am going to start this swap this winter. Does anyone know what is the most machining that can be done to this motor in the area of boring the cylinders?
I'm sure you could do 30 over, but how much can you go?

I really like to see a well detailed engine coming together!! It's a thing of beauty I'm amazed at people who can't be bothered to buy a couple cans of spray paint for an new engine!! After all, with all that work going into it, why not make it look good?? It's be best opportunity to do so.

Yeah, paint makes everything look new, or better than new. The only problem with paint, is that it takes more care to not scratch it. But when an engine looks good you tend to take better care of it.
I have had so many great comments on here and from people who are not into Fieros who see it. I love gaining respect for the Fiero!!!
Thanks for the 3.4L pics. Looking all over the place for 3.4L info. As for the flywheel; was there a different cank used for the '88 vs '87requiring a neutral balanced flywheel? Also, other sites have mentioned retaining the 2.8L heads for the conversion, is that the way to go? billr

Welcome to the forum. Yeah the 87 vs 88 has a different crank. The 88s and 3.4s have a internaly balanced crank where the pre88s had an externaly balance crank. The earier ones have a weight on the flywheel.

I got mine at Partsamerica.com for only $39.99 Just set 'your car' as an '88 Fiero V6 and look up and order the $39.99 flywheel( The part# is Standard Flywheels 6500 )with a $35 core You can order online and pick up at the store. Then take back your old flywheel the next day for the core.
The old '87 2.8L is on the left, The new ''88 2.8L flywheel is on the right. Notice the weight on the old one.
A side shot
The 2.8L Fiero heads are the same heads on the 3.4L both are the HO heads. Some say to use Fiero heads due to a plug that can be a pain to get out in the corner of the head that you have to swap with a sensor. I used the 3.4L heads. Here is the plug
Use either heads you want but they are still the same heads.
sardonyx247 Not wanting to change the subject, butwhat ever happened to that Quad 4 project? Will this 3.4 move in to a 84 4 cy 4 spd, or do I need to move up a few years and get a 2.8? I have spent the last hour and a half reading your great thread. This is on my list of things to do!

The Quad-4 project got put on hold due to me getting this GT. A little more to be done to this then back to it. a 3.4 will go into an 84 but you will need parts from a Fiero 2.8, a V6 computer, and wireing harness.
Sardonyx247- dude just wanted to let you know that in putting my A/C compressor bracket back together after an exhaust manifold gasket change, I referred to your very clean, very sharp photos to get it right. once, again, great job! Oh yeah, and...bump. Cheers Austin

This looks pretty cool.... So its pretty peppy for the driving? What kinda HP are you getting out of it, any idea? Also, I am really interested in this swap, If I can get decent gas milage out of it. Have you figured out your MPG yet?
Also, I understand that you need a V6 fiero engine to do this swap? What mroe extra would you have to do, if you were going to go from a 4cy? Your swap is an automatic, how much harder would it be for a manual? The engine just bolts right on? Thats amazing..........
Great work!

Actually, I just saw yours was a Manual. Thats good, cuz so is mine! So the old fiero transmission just bolts up to the new 3.4L engine? And the cradel doesnt need any welding, or anything to get it to attach, it just bolts right up?!?

Yeah no welding needed.
If you went from a 4 cyl you would need EVERTHING from a 2.8 execpt the block and heads. You may be able to get a dead Fiero with a V6 for cheap or a 2.8 from someone who swaped out thiers.
The transmission just about bolts up(drill one hole, no biggie, takes less than one min) as one of the bolts threads into the tranny from the engine side and the threads just need to be drilled out of one hole on the block. (Pics posted earlier)
Ok. I have read a lot of the posts on the 3.4 engine swap and want to do it. I have had an 86 fiero gt automatic for two years and have finally disassembled it in the garage. This is just for fun. However as it is my first swap, I expect to learn a lot. From what I have read here is what I wanted to go with. 1. GM Crate 3.4L (I know some say this is wasting money, but I don't want to waste the time and the risk of finding a higher mileage f-body) 2. Trueleo Intake and exhaust. 3. 85-88 V6 OCELOT STAINLESS STEEL Exhaust from the Fiero Store. 4. 88 Neutrally balanced flexplat Here is my question. With this setup, what should I do with the injectors, lifters and rockers to maximize performance/reliablity? I don't want to change the cam in the crate engine. (when I say maximize performance, I am not trying to incite any engine swaps debates, I just want to do the most I can with this setup reliably.) Also, what about performance chip? I noticed some comments about a Trueleo chip, but cannot find anything about it on their website? Do I still use the stock electronics? Any help would be appreciated. Sardonyx247 great thread. Much appreciated. Ken

For injectors use #17 or #19 injectors Fieros had #15s Camaros came with #17s some people run #19s. Without changing the cam you can get 1.6 ratio rocker arms. I got roller tipped arms or you could go all out with the full roller rockers. I also got compcams lifters and pushrods.
As far as the "trueleo intake" you can see that I don't use one. I really like the way the engraved Fiero looks and I really DON'T like the way the trueleo intake looks. You can see if I didn't care about looks I would not have painted and powdercoated everything. So I can not comment anything about thier chips or products. THAT IS FOR ANOTHER THREAD.
Thanks for the feedback. Your thread convinced me the best way for me to go is the 3.4 swap. The only thing that I am questioning is can I pick up some additional horses with the Trueleo setup. I would like to get 200 at the crank with simple bolt on changes. Not that I am trying to build a rocket, but have you ever determined what the HP or 0to60 times of your setup is?

i just picked up a 30k mile 3.4 and will be doing this swap possibly this summer or fall sometime. I will def take pics as the progress goes along.
summer or fall.?.? You will want to enjoy it during the summer. It is really not a long swap. I took my time during this swap/write-up. It can be done fairly quick.
I have a ? for you. You had mentioned that to remove the plug for the sensor there was a tool that Snap-On sells. Do you know the correct name for the tool or the part #? Thanks.

The name is "Socket, Pipe Plug, External" I forget the exact size, it is a little smaller than a 3/8 as I ground down a 3/8 extention(but that broke, several times) You can measure the pulg to get the size. They sell both SAE and metric sizes.

I believe I have found it. It is called a "Extractor, Pipe Plug" and I believe the size would be 1/4", correct me if I am wrong. The stock number is E81 and the price is $20.70.
