282 vs 284


Recommended Posts

Posted

what would be the disadvantage to usuing a 282 for a 5-speed swap? any info is helpful. thanks.

Posted

The gearing of the 284 is much more suited to the 3.4, an the trans is stronger. Unfortunately they can't be rebuilt and the clutches are expensive.

282 is about 50lbs lighter, much more common and easier to find, different gear/FDR ratios, can be easily rebuilt, and clutches are cheap.

Can a 282 be rebuilt stronger? Like, so it can withstand a 3.4 no issue? If not, what are the Fiero guys w/ their V8s doing, being careful? lol

Fiero's are much lighter than our cars also.

is there any way to make the gearing better because the junkyard around here alawys has at least 2-3 at a time and they go for $75

They are breaking axles left and right becuase of all that race-winning torque...

the thing is that i dont have a butt load of hp or tq and dont really plan on doing tons of moding. if i got a 282 from a HO quad 4, what is out there to beef it up, i lookin to be between 190-200 whp when done. thanks.

That is exactly why a 282 will be sufficient.

 

I will be running a 282 in my highly modified 3.4 DOHC Fiero, and do not anticipate any problems upfront. We'll see how long it lasts, but I think it'll outlast the motor.

thanks alot, arnt the quad 4 HO 282's 92-94 supposed to have the best gearing???

3.94 fdr i think. any others with the 3.94?

If you got one from a Quad 4, the gearing is better (which compared to a 3.1 282's gearing is desirable - I think the Quad 4's gearing is closer to the DOHC's), but you'll need a V6 bellhousing still. It won't bolt up.

Posted

so basiclly get a quad 4 282, then get the bellhousing off of a 3.1 (or 2.8???) with a 282 and put them together?

A friend of mine broke the axles, if not the 282 in his '88 Fiero GT yesterday at the strip...with the stock 2.8 :lol:

thanks for all the help, i dont plan on running the crap out of my car so i dont think im too concerned with the axles, btw, do i have to get the 282 axles or can i use mine??

Posted

I wouldn't doubt it. With a decent clutch, a stock Fiero is pretty nasty out of the hole. I've ripped some Z28s a new one up to about 30mph.

i think you'd need 282 axles with the 282. i don't think the axles are interchangeable between 282 and 284.

well i think i got almost all the info i need. btw josh, ur car is what made me decide to go for the 282 because i doubt ill ever see numbers like yours and its held up for 4 years right? have you beefed it up at all or is it a stock 282? thanks.

I really wish people would quit asking how much HorsePower a tranny can take...HP DOES NOT HURT A TRANNY....TORQUE KILLS A TRANNY!

 

Until you have a greater than 300-320 ft/lbs to the wheels I do not see a 282 failing anytime soon. My car has 320 if not more right now to the wheels and the tranny with 145,000 plus miles on it at this point and 3 years of driving is as smooth and noise free as the day I put it in the car.

 

As far as the 282 halfshafts....a local guy is using the shafts with custom knuckles in his 1000 HP 980ft/lbs of torque to the wheels Karhman Ghia. His 8 second car has run for two seasons (about 20 races) without even a hint of twist out of them. Now if you have Ching Shin China rebuilds instead of the OEM axles...they will twist like a pretzel. :wink: 8)

actually, i blew the first 282 i was using. one day it just started making noise while cruising at 30mph and i quickly lost every gear. i pulled it out and found this :shock: that was about 2 years ago. fwiw, that 282 had well over 200,000 miles on it when it blew. then i swapped another 282 into the car, which was in there for a year. the clutch burnt up, so i replaced the clutch and swapped in yet another 282 into the car while i turbocharged the car. i still have that other 282 and it's in great shape...it's sitting on my garage floor at the moment. the only reason i put this one into the car is so i could test it (and it's holding up fine....so far :D ). i am very worried about the throwout bearing....right now it rattles pretty bad in neutral and "buzzez" while i'm driving.

all of them i have used have been totally stock, even the clutch is a standard $160 replacement Luk RepSet and it has never slipped once yet.

Now you really think aftermarket axles aren't as good as OEM?

thanks for the info, i went to the yard today and looked around for a 282. saw a few but they were in sohc 2.3's and one was in a 4-tech??? does it have to be the HO quad 4 or can it be any q-4?? too bad i wasnt lookin for motor stuff, they had two cutty international's a 94 cutty 3.4 convetrable, and 95 3.4 gtp. :roll: go figure, kinda sad though :cry:

Never done any tests personally...but anytime I buy Cheng Shin China shit it is useless as soon as I put it on a car...or VERY shortly after! :wink:

 

As far as China's steel factories...cheaper materials ain't always better my friend! And considering most Chinese factories use a higher concentration of "pig" metals to blend...I can not imagine they would be very strong. :shock: :lol: 8)
