Hi guys,

Hope everyone's well

Just wondering if anyone could give me some insight on the difference between running Power FC vs Link G4 other than it deletes the AFM?

I apologize that I realise this might be a repetitive question and there's probably tons of info on both in forums and I have done fair bit of research on this but more looking at people's opinions on the 2 because most workshops seems to say that the Power FC is old and still needs the use of AFM.

What I'm wanting to know is how big of a difference it makes between having and not having the AFM on a Daily Street Car?

Will Power FC be good enough for what I wanted to achieve?

What I am hoping is to achieve 21-23 PSI and about 200-250kw atw

The car is a GC8 99 WRX, I've got so far in terms of mods:

TBE
GD STI Intercooler
Walbro 255lph Fuel Pump
Garret GTX3071R ( not yet in the car )
SSR Unequal Length with up-pipe ( not yet in the car )
Process West CAI ( Not Yet in the car )
Power FC

What I am thinking is selling the Power FC, put a bit of money and get the Link. They are on special now for $1350 delivered till end of May

Again it's mostly street use, I don't think I will ever see Track Days with her so most probably the Power FC will do fine but I've heard bad things about the AFM qnd how wonderful it is to get rid of it and also I've experienced the car with Vipec ECU from the guy I bought the turbo from and was very impressed.

Any thoughts guys?

Thanks in advance

Link all day the new g4+ pnp are on sale this month !! Contact asg or bye performance they can hook you up

Power FC are so old school

Thanks guys for the input...

What do you guys reckon with the Posum Link? Got someone in Gumtree selling for $400?

That is an ancient piece of technology. It should be in a museum. Goodluck even finding someone to tune it.

Go the link g4+.

No one services or tunes the possum unit these days.

The Link G4 is were its at.


You may find an Autronic ECU at the wreckers, a parts, Japan line, or on here. You would pay around 500- 800 for these. There Ok for your old bus

Thanks guys I'll have a look around for Autronics.

On another note I've still got an EJ205 and just wondering if it will be okay running that Turbo with a proper tune of course... because someone told me that the GT Turbo would need a built EJ207 but the guy I bought it from has been using it on an EJ205...

Any thoughts guys?

200-250kw atw is very ambitious on an ej205- it may last a few weeks lol. You need stronger internals and a 6sp transmission to deal with that much power.

Sorry for the noob question but when you say internal do you mean a forged bottom end like a good short block EJ207? Or do you mean the whole Long Block too inc heads etc?

Thanks again for your input

You will be surprised how much a stock 205 will take.
