Cheers guysAwesome job so far man! Really enjoyed reading through this. Neat idea on the bumper beam modification too.
I'm not sure about that tbh. Silverton answers it further down so I'll ask for clarification.Hey have you done any research into where the O2 sensor should be mounted? I think i found that for our cars (only 1 sensor), that is should be about 300mm after the turbo. Not in the up pipe?
I've only done a rough fit so far but didn't see any issues. I can't imagine there will be any as the downpipe will have more clearance to the firewall and everything around it due to the subframe spacers lowering the engine etc.Also how well did the down pipe in the outback? I'm still tack-welding mine up, slowly getting there..
So if I'm understanding this correctly the cars O2 sensor should be in the uppipe?? and if I do a wideband or a/f gauge that goes into the dump??The car's lambda sensor needs to be between the engine and the turbo, the wideband O2 needs to be between the turbo and the catalytic converter. I believe they say 12-18" behind the turbo will extend sensor life.
Yes. Cars O2 sensor needs to be after the 4 exhaust runners have merged together but before the turbo. wideband or a/f gauge sensor goes in the down pipe.So if I'm understanding this correctly the cars O2 sensor should be in the uppipe?? and if I do a wideband or a/f gauge that goes into the dump??
Yeah they are. I'll probably switch the rear bump stops or liberty ones. In regards to the fronts being low, I've heard that the Bilsteins have a different spring top which which makes the Gen 3 front way lower than on the Gen 4's. I only suggest this as mine came out level as you'll see below.Were they gen4 struts? I tried the gen4 struts in my outback, bit too low too. The rear hit bump stops way too easily, the front isn't too bad but i wouldnt mind raising it about 15mm.
Great progress dude! The front end does indeed look mint with everything in there.
I'm kinda torn on engine management as well, might combine project lambda with an FIC6. Although apparently an ecu can only take so many reflashes? Something to think about if considering lambda, you may want to find a backup ecu.
Either way, get something that can control fuel AND timing, at least. And you'll need a voltage clamp or something for the MAP cause it'll freak out the ecu when you hit positive manifold pressure.
...AEM FIC 6 controls fuel and timing, and has a voltage clamp. You'll need a couple 2.2-3kohm resistors tho...
Damn you guy's know so much more than I do. The more I weigh up the options the more I think Lambda is the way to go. Is it able to deal with the positive manifold pressure or will I still need a voltage clamp??Have a good look into a speeduino too. I think they are advancing pretty damn well and theres a guy on facebook who can build a plug n play version. Isaac is his name i think?
Prices looks pretty good too (around $300AUD ish i think)
Cant wait to see this thing go, i'm still trying to finish welding my up and down pipes!
