3.36 diff

[philby26]

hi guys
whats a 3.36 diff centres going for these days?
course spline
Ive got prices at $150 which is not to bad i guess

That's more than I would expect to pay, but it depends where you are buying. A wrecker may charge that much but I would expect swap meets to be cheaper.

I probably have one here which I would sell for half that amount.

But unless you can pick up in Victoria, freight would be a killer.

Hi guys
back again
I am running 175 x75 13 tires which is a lot smaller than the original tire. Would a 3.36 centre be to much
on the gearbox i have a 3.55 in now  but still seems to rev to hard on the open road at 55 mph on the speedo which i guess wouldn't be Right with the different tires and diff centre in it now  i don't really want to change the tires because they are like new and its cheaper to fit a diff centre and i want a good cruiser as i am heading to the mainland this year and there is alot of traveling over there 
cheeers Phil

Phil, I don't think I would be concerned about your car or engine. My car has a 3.55 diff and  70 series tyres. At 70 mph, which I normally try to sit on (it depends on how fast everyone else is going), my engine is doing 3400 rpm. Well within safe limits. These cars did 80 mph with a 3.89 diff, even then they were only doing about 4400 rpm. At 55mph you would be doing about 2500-2800 rpm. This would'nt concern me in the least. I reckon you would lose too much down low to justify going to a 3.36 diff.

Just my thoughts.

Colin.

thanks Colin

I will leave her as is then i just thought it was over reving to much. I didn't want to blow her up
thanks again for the advice

Hey Phil,

Forum members are taking their standard diff ratio's from one end of the country to Orange and back, me included, so I wouldn't worry about yours unless it was very noisy.

PS see you at the Shannons Show on the 14th

Col, I'm intrigued by your comments about revs. I've never had a tach in one of these and like most of us can only go by feel and fear. Is your car stock?

Thelma runs a 3.36 which works well with a warm grey. I've run both 3.55 and the 3.89 behind stock greys. All I can say is that Nev which runs a 3.89 still, seems uncomfortable above 55mph although 60 is ok. My EJ in which I put a 3.55 in was very comfortable (and quiet) at 60. I'm therefore assuming the stock grey "sweet spot" is in that 2,500 - 2,800 rpm range you refer to.

FWIW Phil, if you want to get the full benefit of the 3.55 why not put a set of 185/80/13s on? They look better too because they fill the fill the wheel arches better. Dunlop Maxxis are easy to obtain in this size and have a narrow whitewall.

Cheers
John

John, my car has a mild grey. I've had several stock greys and would have no trouble at all running 60-70 mph all day. Our FJ is stock and is happy at these speeds. Maximum power is produced around 4200-4400 revs. There is no reason why you can't run easily around 2500-3500 revs.
