my n/a box did 10,000 kms max since rebuild and it lost 3rd on me only had 145rwkws at the time
Um yea because they're a dime a dozen over here in nz? We have like 20 vlts in new zealand. I will be changing over to a 25t box, but it's not until the funds come in. Just seeing if you can do minor mods and if it would hold up until i got them, but im understanding what you guys are saying, some last a while, some last very short. But thanks for your feedback
Mf5s arent that weak for the street as long as their fresh they can hold 200rwk as long as u dont go to calder with slicks or something. My mf5 with 270,000ks lasted a year and half with 235rwk then for the last 4months it had 253rwks blew 3rd gear to peice lol and i use to give this box a hammering.
mine lasted 6mths on 11Psi with no cooler started sliping on boost depends on how they have been maintained and how many kms my wagon shifts hard and is a better box than my sedan

alex wat box u got in it now
I have had no probs with mine...although it was fitted with a quick shift kit by the previous owner (I know, not much really!), currently running 11psi, and I think it is starting to slip, but only when I run around in drive, on boost and giving it some. I reckon your box will last a while yet. In the mean time, just go with it and have some fun!!! By the way, I am talking BT1 box, so all this may be irrelevant!
forced_wagon on here has a na auto in his wagon on like 12-15 psi all day everyday, cains it heaps never slipped at all been going strong for about a year

thats what im talking about
iv got around the same pwr now as u a bit more
and i can just tell one of those stock box's would nt last more than a day or two behind my car
NA18 it must of been costly two boxs in a week
does big torque numbers play a big part in destroying box's ?
well no not that costly. im a dif/gearbox specialist and had a couple laying around. if actually done 3 boxes since my turbo conversion but two were in the last week. torque atm is 516nm. im trying to find r33 box as im aiming for 300rwkw with this engine.
yeh im sort of spew'n i didnt do that when i got my'n done
im hope'n the one iv got will hold at least 260rwkws cause ill have that soon
good luck with your's mate

Naturally aspirated, as in non-turbo. Although literally it means 'not applicable'
