I posted a quesiton here:

http://www.skylinesaustralia.com/forums/in...showtopic=99783

but realsied its not the place ot ask quesitons.

So....

those of you who have installler a boost controller, Have you also installer an apexi AFC II and an o2 sensor? In order to eliminate lean/rich running and flat sports around 3-6k rpm?

Or have you simply installed this mod without any further problems?

Cheers

Geraint

It wont fully resolve your flat spot problems with the safc..

it will however aid you a bit more, and fix up your mixtures, so it wont run as rich..

02- sensor-- probably only needed if yours is really that bad.. Just take yours out, and clean it!!

02 sensors decompose with age and need replacing. doubt servicing would be worth it

in my experience, 02 sensors don't play part of your a/f ratio's when you WOT. also i'm under the distinct impression that narrowbands aren't accurate enough to tune your car to

Yeah just get a new 02 sensor, mine was screwed when i got my car tuned after i got my SAFC put it and it kept causing inconsistant dyno runs. It would run something then 5 secs later the max power would drop or increse.

Hey

Have just been through all of this sort of stuff after installing Hi Flow turbo...

Coils

SAFC

-16% fuel etc..

Boost controllers

Fuel Cut defenders

and more

Went to HitMans and had a "safc" tune, $180 and all was sorted in 20 mins....

Left with 215.1rwkws and all is way good.

PM if you want more details.

Ta :P

    • The cross sectional area of a circular hole scales with the square of diameter. So a 2mm diameter hole is 4x the area of a 1mm hole. Not double. The 1.7mm hole is nearly 3x the area of a 1mm hole. You do not need restrictors at both ends of the oil supply line. If you have new, additional restrictors at the turbo end, that you did not have before, then you do not need a restrictor at the inlet end.
    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
