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.

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 :)

      GTX2860R Gen 2 is an option. No, it doesn't actually do much. The basic problem with wanting 600 whp out of the factory twin turbo setup is a few things. One is that the twin turbo piping is just so, so inefficient. The front and rear turbos are not actually working evenly. The rear turbo is always moving more air than the front. On top of this the OEM rear compressor inlet is rubber that likes to collapse causing a huge intake restriction. The merge doesn't even wait until the intercooler to happen, and it happens at a 90 degree angle. This is why you see some discussion about "turbo shuffle", where in certain conditions one turbo can actually force air to go backwards into the other compressor and stall it out, then once the other turbo recovers it stalls out the first turbo in a cycle until you do something to break out of it. The other issue is that the RB26 is just not that efficient an engine. It needs a surprising amount of ignition timing to reach MBT for a given cylinder pressure so all that time in which the cylinder is pressurizing before TDC is just wasted energy. An N54 might be around 10 degrees BTDC on a stock turbo getting into the boost. An RB26 is closer to 25 BTDC. Net effect is a turbo roughly the size of what HKS uses on the GTIII-SS (smaller than the R3/GCG Japan "GT2860-1" -7s) is only good for maybe 550 crank hp or low 400 whp while a roughly comparable turbo on an N54 can deliver something like 700 crank hp and obviously drivetrain losses are greatly reduced when you aren't burning a bunch of power on keeping a hydraulic pump + transfer case preloaded all the time. So yes, you can make a lot of power but there's a reason why people go single turbo for the numbers you're asking about. Don't forget that the RB26 can't even do a straight line pull without oil starving on the stock oil pan either. Baffles can help, but really you just need more oil capacity.

      Found some from 2009. The lobster bends were smoothed out on the inside with minimal gaps (perhaps 2mm) where the silicone joiners were used.

      And if you have to drive it in a civilised (or excessively woke) US state, find a way to register and insure it in a redneck state, so you can roll coal in it without worrying about legalities.
