Well ive been reading that the swap can be done and i am intrested in doing the swap... i was wondering if it easy or hard and what tools are needed for the job. i wanna swicth to posi for preformince. and is there anything i should look for. also i wanna do the full swap meaning i gonna get the rear disc as well. all i know is the best way is getting a 4th gen rear that about it....any help would be great thankz

 

Same as everybody else that asks this question.

Read all the other times people have asked this, on this very page. If you can't find an adequate answer in all those posts, you should consider finding a new hobby. It is discussed on a weekly, if not daily, basis, to the point that there is very little left to add, other than for someone to get out there and do it for you.

Is this response really necessary??? He asked a question if you don't want to answer please don't

 

thankz for the info that is really helpful. i wonder if it worth the hell

 

Only 2 issues with a 4th gen rear swap are 1) ebrake cables, and 2) tires stick out 1.5 inches each side. Also, don't know about a LT1 rear (1993 - 1997) but for a LS1 rear (1998+) you must have 16" wheels to clear the LS1 rear disc brakes.

4th gen rear swap is the easiest cheapest way to convert - most go for under $400 and you get posi, better gearing, and rear disc in one swap that takes maybe 4 hours total.

 

nice i am riding on 20 inch rims so this doesnt seem like an issue and i seems like a do able swap that i can do myself. the sticking out will prob make my car look meaner the only issue i see is the ebrake cuz i have a manual and i kinda need that. hope i can get a good condition one cuz i say just the posi alone for a swap is about 400 buck.... for that ill go for the 4th gen sawp..

 

what are the better gears cuz i am finding two type and i think the manual came with better gearing than the auto i just wanna make sure. also most that ive seen say no traction control that doesnt matter right?

 

Mine are 3.42, and I like them - gives a nice shot off the line, but saves a tad in mileage over 3.73. Most manual cars should have 3.42 I think.

Traction Control I'm unsure of, but ABS won't matter - you don't have the ABS computer system so it just won't do anything. I don't think the traction control matters either, but I'm not 100% on that.

 

I got mine out of a 96 firebird with the y87 package. posi with 3.4 gears. easy to do just some heavy stuff to move. i just bought new brake lines for the 96 and put those on. I havnt hooked up the e-brake. I also use the 96 rims , the offset does not stick out 1.5 inch if you use those.

 

True, if you use the 4th gen wheels then they won't stick out.

BUT - you need spacers on the front to use 4th gen wheels up there, I think 2 in spacers.

 

well what about just a swap from another 3rd gen like a iroc or z28. didnt thoses come with posi and wouldnt it the same about of work or mayb less??

 

You'd pay close to the same price, you'd get 10 year older stuff, and the brakes would not be as good - but yeah, they are out there, just not as plentiful.

 

all i gota say about 3rd gen posi's are this, i bought a 1985 TPI Z28, 2.73 posi 4 wheel disc, 3rd time i got her sideways laying posi marks down the road i broke it, they r weak rears, hell my lil 215hp tpi 305 tore it to shreads lol, they will hold up to a v6 no problem tho

 

No difference strength-wise between a 3rd gen 10 bolt and a 4th gen 10 bolt rear - you just got an already abused rear, and continued to abuse it. Cars are NOT supposed to spin tires. Positraction (lockers, etc.) were developed as a way of reducing tire spin. Anyone can spin tires in any car, shows no sign of power or pride - just idiocy. A true performance car and driver does everything possible to apply what power you have to the pavement in the form of traction, not loss of traction. Spinning tires = broken parts.

 

well yea i kinda figured that there not that plentful of third gen rear with posi. i just dont want my rims to stick out cuz the rims i got is nice and flushed with the car and i like that more than sticking out a bit. but even if i got an abused 3rd posi it would give me a chance to rebuild it cuz no matter what rear 4th or 3rd gen rear i get the posi will give out sooner or later cuz of its age. plus the disc brake is nicer and my v6 is able to make even a weak posi last. i just have to shop around here miami to find a good deal....

 

VERy very very true, but everyone here can say gettin sideways is fun, i doubt one person here thats drivin a v8 camaro thats got the power to get sideways will say its fun, altho not smart lol

 

I was under the impression that "hooking" with slicks break 10 bolts. Any way I'm going to stick my neck out here and say, I have a "upgraded" 10 bolt with 28 spline Eaton Posi.,new 28 spline axles,3.42 ring and pinion with LPW Ultimate support cover and with what power my 5.0 can muster, and with auto.trans and "street" tires(295/50r15s) I should be able to throw anything I want at it with no problem. I even have a unconditional 3 year warranty from a pro.rear-end shop with over 20 years experience that says I cant break it with my set-up. I don't "beat" on it or spin my tires/burn out or drive like a madman but its nice to know if I need it its there.
Hyper Tailz, Its not cheap to do but when the time comes for you to rebuild a 10 bolt just follow my lead with that set up and you wont regret it.( for your manual trans maybe some 3.73 gears)

 

thank to all the input i plan on doing this very soon..... but for now my car just died in the middle of the freeway.... i was heading home from the junkyard and as i was going the car just dies on the spot. i saw my rpms raced to 0. lucky i was close home and my dad could yank me from there but now my car is died. gonna get a fuel pressure check ( i think its the pump) new wires and plugs (i saw they were a lil worn) and go from there.... pffft

 

nice! lol, yea hope its not ur pump tho, pullin the tank has gta b fun, i nver atempted it

 

The rear end has to come out before the tank comes out.

 

lol yea i know it sounds like fun.... but now when i tried it after being home all day and my mind boggled bout what can be worng i thought it was electrical so i inspected the plugs everything was fine so i tried to turn it on and wallah as if nothings worng.... also i heard the pump prime so that partially ruled that out that. but on the rear end matter i saw my rear end snice i was down there anyways and to my surprise i had 10 bolt rear... wonder if that mean i dont need to do the sway ???

 

Not true. All you have to do is support the car on the subframe in the rear with two jacks as high as they will go. Let the rear hang all the way as far down as it will go. Then remove the exhaust (which is the biggest headache of the whole ordeal) and then drop the tank as far down as it will go. You won't be able to remove the tank and the filler neck will keep it from dropping any furthur down but you'll find you can pull the pump out with the tank hanging at that point. It takes a little trickery in how you twist it out but it comes out no problem and then you replace reinstall and put the tank right back up. No need to fully remove or cut access panels.

Anyways glad to hear it's not the pump since you heard it prime and it ran afterwards.

 

yea me to but i know sooner or later it will give but i bet much later cuz i think i was running to rich and when i was punching it around 80mph prob too much gas was being fed and flooded it..... so yea thats my guess. so i guess i can say my pump worked to well LOL

 

woo! getin a 80s posi disc brake rear for 150 this week, woo hoooo

 

nice good stuff there.

 

well its either a rear or headers for the ity bity 3.1, im not sure whcih i wana do yet, headers would look alot better

and damn just found out its not disc but its posi, hmm

WAIT? i gota 10 bolt, its limited slip but last nite it spun both tires and went sideways down the street??? uhhhh limited slip shuldnt do that right??

 

well i dunno i just found out that i have a 10 bolt as well but i havent had time to jack up the car to do the test to see if it has posi or not. but i am sure posi spins both wheels to make ur car sideways i think

 

The V6 didn't come with posi aka: limited slip.

As far as removing the tank, I put a new one in with the filler neck welded on, and I didn't have to touch the control arms or brakes.

And this is how I got my pinion nut off.

 

Well I lifted my rear and when I spined one of my wheels the other didn't so I am guessing I don't have posi well time to shop for a rear I guess
