SAFC did wonders for me. Went from ~140rwkw @ 7psi to ~200rwkw on 8.5psi. For basic "stage-one" mods such as yours they're good to gain that little bit extra. I'm now going Nistune as the car is past what an SAFC can handle.

I've got an SAFC II lying around that I used to have on my car. The unit is in PERFECT condition but I stripped back the wires to bare to which is how I spliced in into the stock R33 loom. You can have it for $180 + postage from Brisbane, I've even got the stand.

It was very handy when I had 10psi and R34 SMIC, 3" exhaust to prevent rich and retard section of the maps. But don't expect to be able to run 15psi and make 220rwkw. Nistune is a good option if you have a bit more $$$.

IMHO, small mods like upping the boost, exhaust & fmic ra ra.. good investment to tidy up the air fuel ratios.

Even change from the stock airbox to a pod filter will affect air fuel ratios a bit, I find that running a pod in stock form makes the car run a tad richer (I've seen it with my own eyes on my old car, using an Innovate wideband O2).

If you're planning just to do simple mods, I see why not.

Yeah that's it, just invest in a wideband o2 and use it to tidy up your A/F ratios.

If you ever need a hand, I can provide that service for a slab of beer, and if you want to get it dynoed with me tidying it up, there are few places that hire out dynos for $100 per hour.

SAFC is basicaly a piggy back that allows u to change ur air fuel mix eg run more boost and not lean it out amongst other things. Best investment I have made is the PFC. Get a good tunable ecu. I gained 30rwkw from a boost increase to 10psi and a tune on a pretty stock setup, just exhaust FMIC and ecu. Then later when u want more u just add ur mods and retune. Find a good tuner your happy with. See what the tuner does best for your car and do your ur research. Purchase. Tune. Happy Days. If your going to mod later why buy a SAFC to tune then an ecu to tune. Its just an extra expense that you will sell off.

not sure im convinced with "waste of money" or "does nothing"

it has limitations and isnt the be all and end all but if you can get one cheap and can get some cheap tuning time you can net yourself some good gains basically everywhere in the RPM range

if anybody else has one coming up for sale can you please let me know? interested as i have similar mods makin around 190rwkw and am not looking for massive gains just a bit of options when it came to tuning. not looking for pfc or nisstu thanks!

SAFC's are fine for mild mods, they aren't as shit as people think. If you're on a budget they go ok.

Exactly true, great for tidying up a/f ratios. Back in the days when I was a broke uni student, the best I could afford was a SAFC. I borrowed a wideband O2, and cleaned up my a/f ratio.

Don't worry about those keyboard warriors, for simple mods on your car, a SAFC is great.

    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
