Hello all,

Before you tell me to search I'll let you know that I HAVE searched and there was alot of data to digest and I did but because there was so many different questions and scenerios I was abit unsure, I thought it was best to just open a new thread to make sure.

I have a small amount of mild mods to my car (turbo back exhaust, ebc, fuel pump, fmic, fpr) and I plan to keep the car this way. I really would prefer 250rwkw as I believe this would be the just right amount of power to move our cars weight, but for now I'd prefer a realiable car with less problems - as we all know the power you have the more problems you are likely to run into.

I am going to build a Jaycar DFA in a few weeks and after alot of research I believe this is my best choice as I am quite happy with the cars power at the moment but would just like to remove the small flat spot I have at 5000rpm on 12psi and if possible, but not necessary, get rid of the REAL R&R (viscous surge).

So my question: Given the amount of mods I have would an Jaycar DFA do what I want to do? That is, to remove the flat spot(s) I get, and if possibly the R&R?

Cheers,

Andy

P.S - who should I ask to tune a DFA? Or should anyone with experience tuning an SAFC/PFC easily be able to use one when given instructions on how to use it? Alot of people have built DFA's; whats the feedback recieved from tuners?

P.S.S - please don't recommend a PFC. I've already decided I won't get one until, and thats if, I get a new turbo/injectors/afm setup. And seeing how Apexi no longer are making them it might prove hard. :huh:

The longer you wait the harder it is going to be to buy a Power FC.

Have a look in the Stagea section and you will find my thread on using a DFA, SITC and IEBC on a Stagea. I have no R&R.

:O cheers :rofl:

PS, the standard turbo won't last long at 12psi.

they dont directly avoid r&r, ie: the safc doesnt have a button to disable r&r it just happens that when it voltage clamps the afm values, you end up in turn avoiding the r&r protection. safcII is now discontinued as well, so you need to go safc Neo

Thanks guy, yep I was refering to avoiding R&R. As long as the DFA can do that I'll be happy.

I can't manage to find a PFC for an R34 GTT anywhere now at all, so I'll be on this path for a while until I manage to find one or look into the ECU remaps abit further.

Have you seen this in the For Sales section

:wave: cheers :blink:

Because the turbine wheels are ceramic as oppose to the usual steel and as such don't take much boost/heat. The R34 compressor wheels are nylon as well.

Cheers for the link Gary but unfortunately that doesn't suit my car. It seems like the DFA is just what I'm after.

I realise they tend to delaminate from the shaft when the temps get up but with a safe tune I dont understand why you couldnt run 12psi through it with all the support systems? Series 2 R33's have nylon compressor wheels too champ.

Cheers

    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
    • Probably. I take it that they are also mentioned to be for R34 Skyline? For example.... RDA has that part as RDA7957. I have the dimpled and slotted version of that on my car https://www.ebay.com.au/itm/285518478694?srsltid=AfmBOopKxMuAFpsxZJdB1cam4D5RAj1f9yJyOttPZLAwXVNCOiwlhrIy This is DBA's top one piece equivalent https://www.ebay.com.au/itm/364246686631?srsltid=AfmBOorbb0XHQgqTvZLgQPhg70nqJtGvdojKnugum3O2LFSr2h-obp8D
