A31 Conversion, Legal Requirements Qld

[VRdrift]

not sure of the exact model my A31 is but its one down from the turbo one, its a 1991 facelift 1, RB20DE with LSD and HICAS,

Im wanting to change this to RB20DET, will this conversion require me to upgrade the brakes, even though mine are the same as the turbo version?

[Mr Eps]

depends where you're from man

i want to say no but i'm not your government...

i didn't change the brakes myself when i converted... i probably should have but i didn't.. not cos it doesn't slow down i just ... wouldn't have minded bigger brakes haha - i'm from WA

i don't imagine you would need bigger brakes though

Dan_J is having this problem.

Nissan part numbers claim that the Ceffy brakes are ALL the same, turbo, non turbo, etc...which are variant to the SR20DET brakes.

Dorigecko has a registered RB25DET Cefiro, with stock Ceffy brakes, because they're "turbo model brakes" the engineer signed it off.

Personally, I think the stock single pot brakes suck the biggest, gayest balls imaginable....4 piston brakes for the win.....no really...they pull up WAY better. They'll be more lenient when it comes to registration if they can see you've gone the extra distance with brakes.

[Dorigecko]

Not only is it registered, but it's passed pits with the standard brakes. Three times. Mine pull up just fine EVEN WITH MY FOUR STUDS OF AWESOME.

Ehem. The only problem I see is that the rear discs are a pain in the balls, because no other car that I've found uses the same discs as the ceffy. Definately not S13 because it's drum in disc on ceffy, hydro/mech clamp for the silvias and skylines.

A brake upgrade is always a good thing, so I say do it aswell. If I had the money to spare, I definitely would too. FFS Nic is doing it on his RB20E ceffy. The only way he's gonna get to use them properly is if he stings it at 180km/h in a school zone with a 10km run up, and needs to stop in 100m because of an 84 year old who looks way too much like a 6 year old child.

And when is that going to happen Nic? When, I ask you?

[adrnln]

If their anything like the guys in Darwin just use the jedi mind control, like i did when I got my car registered.

First question 'Whats a CEFINO??'

Second mind blowing statement.

You can't have that!!! -----> points to HICAS under car.

Its HICAS four wheel steer FROM factory (wave hand in front of face) - Inspector ; Ah Ok.

I dought (IMO) that they will realise you have change from 2 pot to 4 pot brakes. Even going 4 stud to 5 stud (correct me if I'm wrong here) Well they wouldn't here as they didn't notice my brake upgrade.

skyline rear brakes are the same as cefiro (drum in disk rotor) , very easy conversion at the rear , i actually used the drum pads from my 4 stud stuff when i changed to 5 stud on the rear

PURE GOLD

all non turbo ceffy's come with 250mm wide by 22mm thick front rotors similar to the non turbo s13 sr20de

turbo ceffys came with 280mm by 22

if anything upgrade your's to sr20det s13 brakes for cheap

I thought the only difference between turbo brakes and non turbo brakes were the rears, turbo having vented rears and non-turbo sporting solid rears.

[VRdrift]

cheers for the comments guys, Im in qld, doing a brake upgrade is on the cards, depending on weather or not I buy a complete donor car for the conversion, if so i'll go the 5 stud route like I have in the past,

at the moment theres a complete motor/box there if I want it, I may get it if I can get away with the stock brakes,

the fact is the RB20DE is mind numbingly slow, before that I had a 20E one in NZ and that was just awful

woops delete please

toffy, is that the r32 ones? They'd need to be redrilled for 4 stud wouldn't they? I tried with S13 rears without knowing that they were different. Was like.... Where are the vents man. What did these people do with them... But yeah. COMPLETELY different. If you can do 5-stud, go for it. be heaps easier for parts as 32 GTS-T or S13 SR is alot easier to find.

at the moment my rear discs are... well below what they should be. skimmed to within an inch of their life. not happy-making i tell you!

[daisu]

Keep in mind that if you buy a donor car and you want to change to 5 stud, that skyline front hubs won't fit on the cefiro (unless you have a 4wd cefiro).

[Nic_A31]

Hub itself, or the knuckle assembly?

[VRdrift]

cheers, ive done this conversion twice before, but hopefully I may be able to get away with the stockies for now

[faustini]

Hey Ive got an s13. The front hubs discs and calipers are from a part cefiro a mate had a few years ago. I need new dics (these are scalloped now) but cant remember what they were off so dont know what I need to get

are the A31 Facelift / non facelift / 20de and 25de the same discs, or does each have a different setup ?

They are on the car so I cant measure right now, but they were much larger than the original s13 ones I had.

Need to get fresh discs so I can get the rb20det certed.

4 Stud.

Strap for cash so please dont go off topic about 5 studs or re drilling etc etc

cheers
