The old "volvo diff into celica conversion"

[IN 05 NT]

well...today....

i walked into MANNEL motors a 4wd performance shop, and enquired about the air locker diffs centres,

the DANA 30 centre is $1195, plus $175 for the boot mounted compressor and then a couple of hundre to install it, all up the said $1800,

hopefully sell my simmons wheels then go get myself a air locker!

ARB design there diff centres to out last what ever axle the are fitted to....so the idea is that the axle will snap way before the centre will....

hey guys, just thought id update you all,

decided not to go with the air locker,

but found........ A TWINS wreckers in GILBA rd GIRRAWEEN (just down from sss autos)

i got my self 2! lol......hoping to open em up and find an lsd!

hehehe, blake

hey,fellas. wat offset rims do u run? and wat width tyres...
im gonna try and get my simmons re-set, so i wanna see how much i have to have them changed. *originally from a vl*
it may not be worth it though at 450 a corner, plus the original purchse cost, its almost better for me to get them from simmons direct, custom from the start

hey mate,

i have a 28.

i was running 28 offset simmons with volvo diff. these were the wheels that i had with the stock diff. they were 15x8 and had 225/50 series tyres on em.

i am now running 37 offset volk rims. they are 17x8 and have 235/40 series tyres on em.

i have also run a set o 17x9 in rims with a 48 offset (but the guards were lipped by this stage)

be care full with offsets, as the offset that suits changes depending on the width of the rim, also i have a feeling the 28's have wider guards than 23's as the 17x9 rims fitted easily on my car, but steve 23 they didnt suit.

I think stew might be right about 28s having wider guards than 23s, I'm running 16x7" +25 offset F & R with 205/45 tyres, and with the volvo diff this required my rear guards to be rolled. If I want to go to 8" wide wheels at the back I'd need at least a +37 offset, I don't think 8" with a +28 offset & 225s would fit mine without some scrubbage.

On the subject, anyone got some 114.3x4 PCD 15x8" +37 or greater offset rims they wanna get rid of? I'll need something to put some stickies on one day, hopefully sooner rather than later...

And another thing, if you're going through with this or any diff conversion it's a good idea to consider a 5 stud conversion I reckon, it'll make finding those perfect offset wheels that much easier.

[Toy77]

heya,

yeah thats what i did, went 5 stud. does make rims selection much easier, and i think cheaper. i reckon the cost to change the front to 5 stud (ms65 hubs) was ofset by the ease of finding suitable wheels as well as the price.

joel, that offset is what many silvias (s13 only unfortunately in that stud pattern) run. so there are rims in that size, what you may strugge with is finding 15's. i have looked on the silvia forums a bit - plenty of 16's not many 15's as i think 16 were stock????

Cheers

16s would do I guess, just that there seems to be alot more options when it comes to drag radials for 15" rims. Plus the extra sidewall's a good thing too...

[magicmitch]

i know this is an old thread but...would anyone know why my 15x7 Konig Rewinds with 205/50/R15 tyres on them are rubbing?

gaurds have been rolled but not well...and i do have quiet soft suspension

[roadkill]

Hi,

sseing as this thread is sort of being revived. How easily was it to convert the volvo 5 stud to 4x114.3???

Mitch,

Are your wheels rubbing on the outer gaurd or the inner gaurd? What tire pressure are they on? My wheels rubbed the upper rear part of the gaurds cause me diff sits to far backwards in the arches, and they are pumped up to 28psi...

Ben,

At a geuss, as easy as it was to get my hilux 5 stud to 4x114.3... I took it to a machinisnt, got him to weld in the old holes and drill out the 4 studd patern. Cost like 200$ or something to get both done and shorten them down an extra 15mm each...

But i i were you, i'd leave it 5 stud and make the front to match. Its so hard to find attractive 4 stud wheels for cheap! Unles you already know what you want...

Cheers,
jase

Hey mitch,

long time no see.....

what offset are your rewinds?

are you rubbing on both sides?

my car had 8in simmons on the back at the size listed above, that cleared with the factory diff, but just touched with the volvo. ..... but only on one side.

i didnt have an adjustable pan hard and due to the car being lower than stock - the diff was pushed to one side - effectively making the guard on that side smaller.


as for how hard to change stud pattern - i have had both 114.3 x 4 and 114.3 x5 on my volvo diff. both times the engineering company that did my diff did the stud change (from volvo) for me. they weld up the old holes and drill new ones for the studs - then re drill the disc. was not dear - i think $120 rings a bell. cant remember if that was in total or per side. i may have listed this price higher up this thread somewhere.

Cheers
Stew

[magicmitch]

the rewinds have a zero offset..

it mainly rubs on the drivers side..but does also rub on the passenger side just not as frequent. in both cases the it rubs on the outside of the gaurds..chewing tyres up pretty bad...

i dont have an adjustable pan hard rod either...if its neccessary to get one well then so be it..but i lack knowledge in this department so ill give you guys as much info as possible.

[Toy77]

hey mitch,

The zero offset looks like your problem.

An 8in rim with a +28 offset like i had protrudes 73.6mm from the mounting face of the diff towards the guard.

A 7in rim with zero offset protrudes 88.9mm from the mounting face toward the guard....

So basically you are 15mm wider each side with your 7in rims than i was with 8in rims.

The adjustable panhard is a good idea - and is not very dear. if you look at your car from behind, (or use a tape measure from tyre to guard) you will see that the diff is pushed to one side.

unfortunately mate, it looks like you will have to lip your guards - hopefully you will get enough from that so they clear. the pan hard will help even the scrubbing - but if you are hitting both sides, it wont fix it.

If you want me to explain any of this further, just ask.....

Cheers
Stew

[Smokey228]

Like Stew said, if its rubbing both sides than your not going to escape your rubbing with the panhard rod, but i will even it out...

I rolled my gaurds the other day, took one hour, a hammer, and some chipped paint on the inside of the guard, but with patience, it can be done without damaging to much paint...

Maybe its worth lifting the car slightly in the rear, it may not be as visually appealing, aswel, it will more than likely put a big dent in your handling, but it will stop scrubbing!

Cheers,
Jase

[Toy77]

Yeah,

i forgot that i also lifted my car as well.....

but only because when i got the new springs - we didnt take into account the weight of the sub box - the the rear sat lower than the front. i had the rear springs reset.

Honestly though - raising the rear will probly help your handling unless the car is very well set up at that height - most our cars are lowered past optimum handling - BUT it does look cool!
