A rebuilt and hi-flow turbo just became availible to me at a very good price.

I want to run ~16psi (I understand 18psi is approx highest on standard internals)

Will just SAFC be good for 16psi? Or need PowerFC?

I hafe:

- Turbo back zorst and hi flo cat

- FMIC

- upgraded clutch

its not about how much boost, its about the amount of airflow :type:

i wouldnt run this airflow with only the safc, youll benefit much more with power fc

i wouldnt surprised if you just get boost cut all the time from the stock ecu, way too much airflow @ 16psi

I have a 94 gtst and havent had any problems at over 1 bar, the highest ive ever run it was 1.2 bar, after pulling my turbo off it was apparent that it had been rebuilt/reconditioned recently so its not quite as dangerous as doing with the standard turbo :rant:

my dyno power curve at 0.9bar is dead straight with constant power gain,

180.3 rwkw with the afr's in the very low 10's

i dont think the standard ecu is as weak as everyone thinks, its probably most of the other systems that stuff/support with it

i think the standard ecu can support 220-230rwkw if everything else is done properly + piggybacks

    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it. Have a fish around amongst these hits https://www.google.com/search?q=surface+mount+transistor+m33&sca_esv=9cb49794e0b2005d&source=hp&ei=2vJ5aNjTB7Kw0PEPldnS8QM&iflsig=AOw8s4IAAAAAaHoA6qkfmF6XcygtrZ4Vu9f92NXF_RFd&ved=0ahUKEwjYqIPP7MWOAxUyGDQIHZWsND4Q4dUDCA8&uact=5&oq=surface+mount+transistor+m33&gs_lp=Egdnd3Mtd2l6IhxzdXJmYWNlIG1vdW50IHRyYW5zaXN0b3IgbTMzMgUQIRigATIFECEYoAEyBRAhGKABMgUQIRigAUjKCFAAWABwAHgAkAEAmAHfAaAB3wGqAQMyLTG4AQPIAQD4AQL4AQGYAgGgAuYBmAMAkgcDMi0xoAfMBLIHAzItMbgH5gHCBwMyLTHIBwU&sclient=gws-wiz
    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
