hey everyone, picking my new ceffy up this friday and got a few questions for use!

quick run down of the car

rb20det with the usual mods

stock turbo running stock boost

fmic

3 inch turbo back

pod

bov

ebc

alloy rad

oil catch can

carbon clutch

hsd coilovers

17 inch alloys

body kit ( unknowen brand, think its a monkey warehouse )

boost, oil and water temp gauges..

the car is in good condition other that the front bar being cracked, not sure if it can be fixed or if its easier to just get a new one. body has a few stone chips as you would expect.

engine wise its very good other than it has a boost spike problem. im not sure if the ebc is hooked up wrong or if its somthing else. i know you get spikes with bleed taps but only a few psi but this thing spikes 5psi.....

anybody know why it could be doing this as its the first thing i want to fix before i do anything to the car?

also like most cefiros it was auto but now is a manual and it has that beep beep beep thing when you put it in reverse, what wire do you cut to stop this?

going from the list of mods already done to it what would be the next thing to do? it will be getting a full survice after i pick it up and the injectors cleaned by a racing buddy who works at mike vine turbos.

im not to sure about the carbon clutch as sadly the missus might have to drive it the odd time, what would be a good clutch setup for the street thats easy on the left leg?

fuel pump is stock so was thinking about a wallbro intank with a fuel reg!

how hard and what mods would i need to do to get around the 170-180kw mark?

i live out in the sticks and closest cops are a good half hour drive so dosnt have to be 100% legal as ive got a screamer pipe lined up for it...

Probably your EBC, the factory tubo setup takes around 1000-1500 rpm to get full boost under most acceleration.

The reverse beep is from the time control module? thingy or one of the modules under the collumn, cut that and you get more problems, your main ones being your alarm will be inactive, HICAS will go off its chops, no auto-door locks when you start moving, no interior lights, etc

its one of those things most people cut not realizing what else they take out with it.

im not to sure about the carbon clutch as sadly the missus might have to drive it the odd time, what would be a good clutch setup for the street thats easy on the left leg?

Plenty of factory similar RB20 clutches around, if you want balls, keep the hardcore clutch, you can compromise between heavy duty clutch and easy pedal with a bigger cylinder, Nismo make one and you can get it off SlidingPerformance.

Check your tank and give it a good clean before the new pump, obviously, no point getting a flash pump and running a small bit of rust through it.

Search this forum, been covered dozens of times of where mods take you, keep in mind our Cefiro's are identically setup to R32's, so just search for RB20 mods, same when looking for aftermarket gear, dont get shafted because you used a rare name.

Dont go doing too many illegal mods, cops might be a while away, that means the pits are a while away from you if they do actually go out there and slap you around with a yellow.

Boost spike will most likely just be a tuning issue with the boost controller, they are abit fiddly to set up.

No need to get a fuel reg even with an aftermarket fuel pump.

Should be able to see those power figures with a bit of boost and maybe an SAFC to tidy up the tuning. Maybe consider an RB25 turbo?

ive been thinking about a rb25 turbo, whats a safe boost level with them? i know the rb20 ones are only good for about 13-14psi before they start falling apart. also read a thing about the hypertune hi flows, seem like good bang for your buck!

i have a 25 turb on my rb20 r32, goes sweet, i run it at about 12psi everyday and it pulls nicely - good bang for buck

i think at 15pound mate the stock injectors tend to max out,

check out the forced induction section, there is ample info there :)

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
