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?

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.

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?

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.

PURE GOLD :blink:

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

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

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!

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

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
