I have a 85 gt, for the stock wheels it has 5X100 bolt pattern with 57.1mm center bore and 42mm offset, the stock tire size for mine was 215/60r14. 14"x5.5" stock wheels I put 17"x7" tenzo wheels with 215/40zr17 tires. Its almost the same rolling diameter as stock, so the speedometer is 1mph off at 60mph. doing 59mph, shows 60mph. I used a tire size calculator website www.miata.net/garage/tirecalc
Yes, sort of, The clutch is different.
There is someone with a Olds 455 in his Fiero, but he had to remove the trunk.
NO
Yes it will fit. All Fiero windshields are the same size. They only vary in the amount of tinting or top shading.
no
Yes, a 3.1 will fit in the Fiero. They are the same block.
There's a kit for that. Check the internet for fiero clubs and ask around.
Rims and tires from a 2001 Pontiac Grand Am will fit on a 2003 Pontiac Grand Am. They have the same lug nut pattern.
Assuming you are speaking of the front hood, and not the rear engine cover, yes, the 1987 hood will fit the 1984 Notchback. All front hoods are the same, 1984 through 1988. There is a vast parts interchangeability including exterior, interior, electrical, chassis, engine, and transmission, with the 84 through 87 models. Some changes were made in 1988, for instance larger brake rotors, better suspension, etc. so not as many parts are interchangeable with the 1988 and the other years.
The 350 wasn't available in the Camaro in 1984, and even if it was, the practical answer to your question would be NO.
yes, its not a question of what will fit...its a question of how much money you want to spend.
No, Fiero seats are pretty special to fit in where they are. I recomend you repair your old with parts from the fiero store.
