im expecting about 200 rwkw on the stock turbo with supporting mods.

I'm aiming for the same. You went an SAFC II?

emanage ultimate

It's a little more pricey yeah? Removing speed limiter is a must, i don't want approx. 200rwkw and then limit it to 180km/h, then there's no point making extra power :P

i went pfc but safc will be fine but no speed cut maybe get a safc2 and a speed cut defencer to save on cost from what ive read emanage ultimate is a very good piggyback if you find the right tuner to install they are like 800 + 500 for tune which is far less than the 1500 + 500 for a pfc

I Sold my SAFCII to my brother for $200, Unique is goin to fit it For $150 & Tune for another $150, $500 all up.

If your going to do major mods later I would go for SAFC option

I Had FMIC, Boost control and SAFC had approx 200Kw atw pulled 13.3 1/4 mile on 19"s

i agree safc+rsm cheap and effective

Good point fellas. So it'll work out cheaper to get SAFC II & the RSM together + tune rather than something expensive like an EMU or Power FC...

I'm gonna head down that path by the look of it.

Ahhh can i still achieve 200rwkw without the SAFC? I'll end up with one anyway because the factory fuel maps don't milk maximum power i know.

Just get an ecu. You already said you're gonna upgrade th car in the future.

its not the cheapest option for sure, but its the best.

we don't drive skylines to save cash now do we...

i have done it mate. from memory it is wire 32, dont quote me on it though.

nothing bad has happened to my car, it is better than ever.

besides u only cut the speed/HICAS diagnostic wire.

besides u should remove hicas anyways....get a lock bar

UPDATE: I took the 33 for a run last night to see when the speed limiter cut in. I hit 180km and nothing happened. The speed gauge continued to increase into 'nothing' reading, i'd say it hit 190km before i backed off.

What's the story here? Doesn't the limiter exist? Or does the dail only SAY it does 180km?

ALSO installed an R34 side mount intercooler...made a BIG difference so i think i'll hold off on the front mount for now, and save for an SAFCII + tune.

Cheers :angry:

It does exist. But the combination of the speedo being out at high speeds, and the fact that your rims are probably a different radius from stock result in your indicated top speed going over 180kph when you hit the limiter.

Good point, they're 17's on now. But i thought AT 180km the ECU would kick in, regardless of the rotational speed of the wheels.

Is there a way to find out if my ECU is modified? I removed the kick panel and had a looksie but i'm unsure of what's what.

Cutting wire 53 removes the speed limit and no it doesn't get rid of your Hicas, whoever told you that is an idiot, its the speed signal wire and the Hicas diagnostic wire. From your gearbox you have a speed signal wire into your dash, then from your dash to the Hicas computer in the boot and to the ECU in the kickpanel. With it cut your car will do about 230-240 with basic mods.

The reason people say that you get rid of the 180 speed limit with aftermarket computers is because aftermarket computers don't have this feature built into them.

Another reason why people say that the SAFC or RSM removes the speed limiter is because they use the speed signal wire......which most people cut and wire to the SAFC or RSM, see the pattern here? It's all to do with that one wire.

Aahhhh makes sense now hehe. Thanks mate, i'll take another look at the ECU. If i feel confident i've found NO. 53 i'll give her the chop :wave:

Looking forward to freedom lol

speed cut comes in at 5,000rpm in 5th gear which in my car is 190km/h... which I hit about 3/4s down most straights ON THE TRACK

I can't for the life of me think why you would go bother chopping wires other than then you can brag to your mates about how quickly you were going when you got done for speeding......... and how for the next 6 months you will be needing a lift;)

    • Shove more foam in it as a minimum if you possibly can. Or steel wool (not the stuff with soap on it!) Baffles / getting the oil out of the air is huge, and should be done at both the cam cover, and the catch can.   I'm about to do a power steering reservoir, and even that needs some thought to make sure air is separated from the oil, to stop evil Cavitation. I'll probably look at doing my own catchcan later on too.
    • I was once told, who it was I'm to old to remember, that the length of the OEM wheels brace supplied with a vehicle is designed long enough for a average person to apply enough torque to do up, and undo the wheel nuts to the specified torque  What a average person is is anyone's guess though, i.e. average fat bastard, average knuckle head, average perfect sized human......like me Unless of course, a tyre shop has ugga dugga'd them up to "torque to yeild/strip" specs, used cross threading as natures lock tight, or a big breaker bar was used to tighten them up to get some nice stretch in the poor old wheel studs Me, I torque wheel nuts to 1 elbow joint click, lower torque settings are based of wrist clicks, higher torque settings are based of shoulder clunks, or total dislocation for anything that requires all of the torques 
    • I think the catch can design is pretty flawed. Evident in the fact that the V2 one moved to a larger top mounted filter which alone would have helped with overflow and reduce restrictions compared with the side filter. I also imagine there was a major improvement to the baffling design. It is worth mentioning that this catch can with the RB20 was never as much of an issue and the high kms RB25 is likely a part of the problem. I have gotten quotes for both a new "Vibrant Gen 3" catch can and to modify this existing ones but that may have to wait until after the track day. I hope the sump/head breathers/drains and cam splash plates will be enough
    • Yep, both. The ratio is 1.8 instead of OEM being 1.7. The rocker bodies are modified with a larger bolt hole and re-threaded with 10mm holes instead of the 8mm YT has stock. Finding out they don't actually fit the stock castings cause a lot of un-impressment by the person in the USA who tapped the new holes for the 'upgraded' YT product. He was very unhappy with them given their previous design did not require 'clearancing'
    • That too, but I think this is why she's put the work into the cam cover baffles. I mean, a catch can should only need to be a catch can, not an oil air separator also. Not to say that putting the effort into having it do a better job of oil-air sep is a waste of time, but doing the sep earlier is always going to make life better. And that should happen now anyway.
