Jeremy's A31 Cefiro

Hey everyone. I'm new to Nissan's with this A31 Cefiro, but luckily, I'm in the motherland :laugh:. I just picked up this Cefy, and luckily she is old enough for me to take her with me when I have to leave in September.  Nothing definitely solid as far as plans for her yet, but I do kinda have a general idea.  For now I'm going to stick with the RB20DET she came with since that will make it easier for me to ship and import if I have to go back to the US.  So for now I'm looking to do cams, injectors, and a bigger turbo, along with a standalone ECU.  Haven't decided just yet on the interior, but I really like the look and feel of the Bride Euroster seats.  The car is pretty much bone stock other than some basic audio upgrades.  Anyway, here she is.

Haven't been able to do much on the car lately other than acquire parts.  I did manage to put in a set of Splitfire coilpacks, replaced spark plugs, changed oil, and replaced the air filter.  So far I've managed to stockpile a set of LMGT3's in 17x9 4 lug, a set of S13 coilovers (HKS rear and KTS fronts), a Nismo 2-way (I need to find an ABS rear end though so I can build though so I can build the assembly then just put it in the car instead of the car being down for however long it takes me to do it), a Haltech Elite 2000 with patch harness, and a stock R32 GT-R crankshaft.  This is in addition to the body kit I bought from a friend, RB25 block and transmission.  So far the plan is to drop 26 internals into the 25 block and build for somewhere between 400-500 HP.  Also, I found out that I am going to Ramstein, Germany next, so I'll only be about 160 km from the Nurburgring.

Someone with more knowledge than me should know if it's even possible (I don't think it is), do some googling. Plenty of people on here pushing 320+rwkw on stock rb25 internals. Just freshen the stock motor up and you'd be good to go. Putting a RB25 neo head on a 25 is just as good as having a 26, without the oil issues.

Sorry, for being completely AWOL on the thread lately.  Got busy getting ready to move and everything.

Status update:

Got the LMGT3's mounted but was slightly mistaken on the size. The fronts are 17x8 and the rears are 17x9

Also, ignore the flat tires, they were aired up right after the picture was taken.

The suspension will be sorted out once I get the car fully registered so that nasty wheel gap will go away.

Trying to decide what the next upgrade/project will be.  I have the Haltech that I can "install" since it only requires swapping two injector pins on the harness.  Has anyone used the supplied RB20 map to run a stock engine? I'm assuming for completely stock it should be pretty accurate.

I also have the Nismo 2-way that I can put together.  I kinda want to look at changing the ring and pinion to get a different ratio.  If I remember right the Cefy is 4.3 which keeps the revs a little high for autobahn driving.  I'd like to see about swapping to a 4.1 or maybe 3.9.  Has anyone done this on a Cefy and have can give me their take on it?  Hopefully I will be more consistent with working on the car now that I will be here for a few years.

No real progress on the car since the Nismo wheels had a leak around the valve stems, so I'm waiting on replacements.  For now I'm using the original wheels with some cheap winter tires I picked up.  Once I get up to decent speed (90+ km/h) I get a lot of wind noise, so I'm looking to replace all the rubber door seals.  Does anyone know of a good place to source those from?  Also, I want to adjust the latch on the doors as a couple of them seem a little bit looser than I think they should be.  Anyone know the process for doing that?

Minor update, I think my headlight stalk shit the bed. My headlights got to where they would switch on the high beams with no gauge lights. Checked the fuses and relays. Fuses were good and best I can tell the relays are good too.  Tried to clean the contacts in the switch and got one low and high beam to come on left side, nothing on the right side.  So anyone got an A31 or C33 switch they don't mind parting with? Needing something ASAP to get her back on the road. All other projects are sidelined until I can get this sorted out and I really don't want to attempt wiring in a toggle switch if there is absolutely any way to avoid it.  I found a post from Dorigecko about 8 years ago saying he had one, but that was 8 years ago lol.

@Swz3 Thanks.

Finally got off my lazy ass and did a little bit more work on the car.  Not having my own garage anymore really sucks.

I tracked down a new headlight switch and got that put in.  I also installed a USB port in the center console instead of having wires trailing from behind the head unit.  In addition to cleaning things up a little bit, it also allows two phones to be plugged in, one charging and one sending audio to the stereo.  I also finally got around to replacing the valves in my LMGT3s.  While I had the tires off, I split the center off and plasti dipped them black.  The wheels need to be refurbished anyway and I will get them professionaly powdercoated/painted then, but wanted to test the look for a bit before I spent that kind of money.  This weekend (hopefully) I will get around to putting the suspension on to bring it down a little bit.  We'll see what happens after that.

    • Nice, thanks for sharing your progress....that's a pretty long list you are putting into it!
    • Decided to upgrade my pressurised plastic coolant expansion tank for a fancy pants alloy version The OEM versions can get brittle, even the new plastic one I got when I first got the car is a starting to show signs of "stress" I wasn't cheap, but it is basically unbreakable
    • Morning all, I have an RB25DET Neo that's in need of a rebuild. Will need new pistons etc due to detonation damage. Would anyone be able to recommend a shop in Southeast Queensland who I could bring my long motor to for a rebuild? Just want someone who knows RBs and whos built a bunch of them before. TLDR - recommended engine shops for RB rebuild.
    • Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -  
    • Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.
