3400 Fiero

[bandit307]

So I have the swap on the way so i figured i would start a build thread.

Just some starter pictures.

[bandit307]

I now have the 2.8 off the craddle and am getting ready to clean up the trans and cradle. Waiting on parts right now, so just getting everything preped.

I was hoping someone could help me out here. With the 3400, is it as simple separating the trans from the engine as it is on the 2.8. I have all the bell housing bolts out and the dust shield off the starter. does anything else need to be done to separate the two? I just dont want to damage anything and i have never worked with a transverse auto before. I dont see any access to get at the tq converter to unbolt it from the flywheel, So i imagine i will have to make a mess pulling this apart.

LOL, the wife is gonna be pissed when she finds out you stole her engine out of her grand am!! j/k Or is that a rental that's getting a fresh new 2.8 swapped in before it's returned? LOL

No idea on the separation, but make sure you got all bolts out, there are a few hard to get to ones (well if it's still in the car LOL)

[bandit307]

I have all the bolts out for sure. I just dont want to try and separate it before i know thats everything. Cause on the longitude mount transmission i have pulled out i have unbolted the tq converter from the flywheel and it prevents a big mess. But I dont see any kind of access on this trans.

This is the 3rd Trans in the GA and it blew again, so I have given up on spending money on the GA. Thats why im pulling the engine for the Fiero. The wife is sad to see the GA go though. lol, but what can you do.

[IsaacHayes]

I think you gotta unbolt them, but I don't know for sure. Never did one myself.

The trans in the GA, were they rebuilt by a shop or junkyard replacements?

[bandit307]

A shop, The first shop gave me my money back cause he had to rebuild it 3 times in under 10,000km and the trans that is in there now blew the pan gasket cause the pan was dented. Stupid shitty roads.

[IsaacHayes]

Sounds like they did not know what they were doing. That's why when mine goes I will rebuild it myself.

Yes, you have to unbolt the TC from the flywheel. You should be able to access the bolts from the starter dust shield area. On my car (94 Beretta w/3400 and 4T60E), there are like 2 or 3 dust shields total, and all have to be removed in order to get to the TC bolts.

be patient tho, i did this recently on a blazer....little movement available and it took longer than i thought it should. put the 3400 and trans back on the lift and get it up in the air and work on it...ur going to have to get under it.

[bandit307]

Got the tranny unbolted from the 3400, it actually wasnt as bad as i thought it would be. I believe my clutch and flywheel came in today via ups, but i wasnt home. So i will have to wait till tomorow to find out.

Aslo built a lower engine mount using the stock 2.8 mount with a little cutting as seen below. Now comes the wiring.

I ordered new poly mounts for the cradle but i am not to sure on how to change them out, any advice?

[Canyonero]

You gonna need those fiero valve covers?

[bandit307]

You gonna need those fiero valve covers?

No I dont think I have any use for them.

Clutch and flywheel came in today. Just a couple update pictures.

Nice!

So (random question) do you fiero guys have problems with axle breakage like us FWD guys? I've seen some fieros pulling wheelies in videos.. that's why i ask. lol

I have heard of some guys getting custom axles made up instead of using cv axles. Which makes sence since there is no need for the cv axle in the rear.

But also from what I am told, the original axles on the Fiero are pretty strong.

A lot of us Fiero guys get lucky. Usually if we break an axle, we also wipe out the trans case from the diff side-loading. I just did the same swap as you a few months back. Turned out great. I don't know if you are planning on it, but you can use the fiero timing cover and accessory mounting Looks like a stock motor except for the valve covers and intakes. I turned the fuel rail around to mate to the factory lines, (had to bend a bit). Then just fab up a custom dogbone. I used part of the factory one, and some 1/4 plate steel bolted to the side of the head. Worked great! I'll try to get some pics up
