You forgot engine rebuild after FCD. Sure, some of us can get away with full exhaust and intake on a stock fuel system, but some of us can't. I say beef up the fuel system before the exhaust.

Yes, especially on s4(s), don't go beyond a 2.5" dp on a s5 and you won't have wg issues...But atleast get a fuel pump.

My wg is ported. It makes me happy.

Alright. I've been told to run 720 secondaries, Walbro fuel pump (size?) and a s-afc first. Then add my other mods.



On rx7club.com, someone talked about openning the wastegate (leaving it open) what does that mean?

get a stand alone first https://www.nopistons.com/forums/pub...R#>/unsure.png

So at what point (injector sizes, boost levels) does it get past the point of running an oem ECU with a piggyback and get to the full blown standalone?

I believe its entirely up to you. If you got to a point where you keep on buying more piggy backs, switch to an stand alone. At Microtech prices, I believe almost everyone should switch to EMS after all the exhaust work has been done and you have to go buy a FCD and an SAFC. Just in my opinion. I'm pretty sure other people have different views.

if you are planning on opening the exhaust, putting a intake on and messing wtih the fuel **** you might wanna consider getting a halltec or a motec system. and get it tuned.
