About to place the Order for the RB20. Question, Can the PFC drive low impedance injectors? I know the R32 RB20 is High impedance. I have a set of low impedance 660cc injecotors that I am goin to use. Do I need to add inline resistors to use them? And Thanks for pointing me to the PFC for the RB20 guys.

Whatever happened to the Yanks building tough 10sec untubbed RS Camaros??? We seem to be getting a lot of posts about RB engines...can i guess, RB20 in an S13 (240SX)...all good though!

As for the Apexi Power Fc for the RB20DET, i think you will find that new they are harder to find then other PFcs intended for other RB engines. 2nd hand they are rarer again.

And you are right, the Power Fc requires injectors of the same impedence as factory, so yeh you need high impedence injectors if you are to use the PFc. I have just finished wiring in a resistor pack off a GTR to allow me to use low impedence GTR injectors in my RB20, and was surprised how easy it was to wire up. If only i coudl find a Power Fc for Aus$1,000.

You can run a RWD PFC with low impedance injectors - only need the resitor pack wired in (have got it in my ECR33 - low buck GTR 444cc injectors are used w/std GTR rail). Turns out a hell of a lot cheaper than buying side feed injectors.

roy, you are joking aren't you??? surely brent from nengun can get you one for ~$1000

About 12months ago when i tried him he wasnt able to help me out, perhaps if i dropped him a line every 2-3 months, or tried again he could help me out...i dont know.

For the time being though i dont really need an ECU, and if i do go down the aftermarket path in the future, i now want something that can hold different MAPs with the click of a button... so not really looking for a PFc now.

Oh...and the best place for part numbers is www.meggala.com.au he does a good job of collecting tidbits of info for us Nissan owners, other then that im not really able to help you

      Blue slip

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?

      You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height

      Ethanol Content Sensor - Always at 11%?

      By Duncan · Posted

      yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia
