This is my first post here, as I just got my first Fiero
. As my username suggests It is a 1986 Fiero SE, 2.8l L44 V6, 4 speed manual. It is in great condition, with only minor work needing done to the paint and some reaseembling of the interior. It spent the first 18 years of it's life in Florida, and had been garaged most of the time and during winter ever since. It'll soon be parked off-ground and covered with me since I have no garage. The brunt of the work needing done is the engine needing reassembled, and all the work that goes along with it.
I'm not complaining though. The car was given to me by my Father, along with all its parts and a ton of spares. I'm honored to have it, since it was his baby. He always told me it would be mine someday, and although he would have preferred to enjoy it some more and give it to me whole, long story short 4 years at the shop that never finished it was enough.
The car only has 73,000 miles. Previous owner before Dad had run the heck out of it, necessitating the rebuild. Dad had already upgraded many parts on the car also.
So, now I have an engine to reassemble. I already have the complete kit, even the new cam ,pistons, rods, lifters.. the whole shebang. New stock output Oil Pump. Cylinders have been bored .030", heads are done with new valves and springs. I even have the official shop manual, a Haynes, and a Chilton. Only thing I DON'T have is a new crankshaft. That is the point the mechanic had gotten to, to let Dad know the crankshaft was just under spec.
This brings me to my questions. I've done a TON of reading, and see mixed opinions. When I measured the crankshaft, all journals were consistently at between .0017" and .0025" below the low spec in the official shop manual. All the bearings I have are stock size, Enginetech rebuilder bearings. First.. I was like.."Well, better get a new crank". Then I looked at the clearance tolerances in the shop manual, and decided to plastiguage it.
The Clearances in the shop manual are(covnverted from mm):
Main journals .0016" to .0031"
Rod Journals .0013" to .0037"
By the plasiguage, my main jounal readings were from just under to just over .002"- worst was flattened much wider than the .003" thickness. For the rods, exactly the same. I'd say the worst reading of all would be .0022" on one rod journal. Out of round on all journals is within spec, and they have all already been polished.
So, do I dare run this crank, or am I just asking for trouble? On paper, it is fine, but then again I keep reading about oil pressure problems and the like with these engines. The engine is also just being built to stock, except for the .030 overbore. Yea..logic says everything else is new so just replace it and get it over with, but in these times and our house, $220 plus tax is a big number.
Here is a picture of the car, just after we towed it here, no engine or tranny in it, and parts boxes inside, lol.
I'm sure the Formula markings were put on by someone just for show, since the Formula model didn't come out until '88. It doesn't look bad though since it is the same bodystyle as one lol. I also have a set of Fi-Air-O over the roof scoops on their way as soon as the mechanic gets them back from his friend that repaired one. I know their are mixed opinions on those also. What intrigues me though is when Dad was in Florida(2004), he did some research on this car's VIN on one of these forums and found out that there were only just above 500 of this exact car made.. options maybe?..not sure.
Thanks for reading this long winded post, and it's great to be here
