on the dyno we were checking fuel ratios and up to was getting towards the lean side. 12.5 i think the reading was. i dont fully understand how it all works but i have told the bloke i dont want to boost it up and have a fast car that lasts a couple of months. my car dosn't feel frinnished at the moment. only feeling the pull of the turbo from 4000rpm onwards. mechanic wants to get it back on the dyno and check fuel rail pressure, timing etc to make sure car is running safe. he was talking about fuel cut defender and other stuff that is going to go on the stag. what is a SAFC and what does it do and how much does it cost because it sounds like i need one?!!??!!

I've got a GT30 turbo on my series 2 stag and have only recently got a 3" full turbo-back exhaust fitted and now the turbo hits full boost around 3000rpm or maybe even less. Really pulls nice and hard with almost no lag. Before I had the exhaust fitted the lag was very noticeable but now its only ever so slight. One reason is that the turbine now spins more free and another reason is that the engine breathes better and therefore builds revs quicker.

I'm getting a safc2 fitted this week. Basically they just sit between your air flow meter and your ecu and modify the voltage that the ecu sees - enabling you to accurately tune your Air/Fuel ratios. Instead of running rich or lean, the SAFC can correct the AFR graph so that you're running much safer and more economical. You will also see improved performance as a result of your car being more efficient.

Hope that helps. It does have limitations but provided your AFR's aren't too way out then you should have great results with it.

Personally I'd get one of these before a fuel cut defender. Probably depends how much boost you're planning to run.

this might sound real stupid at this stage...but what is a GT30 turbo? is this a stock turbo...if so..which car? is there an advantage of using the GT30 turbo over hi-flowing the stockie ...in terms of turbu efficiency and $$$

Have a read through this topic should shed some light as to the possible advantages, disadvantages and what a GT30 is.

Cheers

      Yeah, I don't believe the M35 uses a deadhead system.

      Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.

      Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By GTSBoy · Posted

      There's one for sale at Grand Auto Wreckers in Lonsdale (SA), for .... let's suggest the sum they're asking for will make you cry. You may have to embrace the idea of modifying the rear subframe to accept some other diff. You could probably find a way to wangle a shortnose into there, with a custom rear adapter and some sort of shenanigans to relocate the front mounts. This has probably already been done by others, so there might be some guidance available as to how easy/impossible it is, out there in the googles. But you possibly needn't restrict yourself to Nissan diffs if you're going to contemplate that. There are similarish Toyota diffs, possibly some Euro ones, possibly some Seppo ones.

      The ball joint taper and arm taper have to match angle and diameter, but just doing the bushes is a much better option.....seems like the industry moved to "it is cheaper to replace the whole arm than take on the labour for changing this bushes", glad the aftermarket supports it
