Gents,

A couple of questions I'm asking in preparation for my EBC installation:

(Background info: My car 1996 R33 S2 GTST stock turbo)

1) Currently a air line runs from one of the solenoid ports to a point down stream of the AFM (but before the turbo). Can this line stay as is?

2) Must the old solenoid be unplugged? I'm reading conflicting advice...

3) See attached - is this a good vacuum line to tap when running a vacuum line direct to the boost controller?

You need to get rid of the standard boost solenoid. Unplug it or what ever. Your objective is to fit your boost controller inbetween your hot pipe and your actuator.

I wouldn't use that. Its going to be using a boost source inside the TB. The best place to get your boost source is right infront of the turbo outlet on the hot pipe. You have boost reading almost directly from the turbo which will give your boost controller the quickest reading so it can respond and work quickly.

1) The line that goes from factory solenoid to AFM pipe can stay, the factory solenoid, when unplugged, is shut anyway. Or you can shut it off. Or use it on atmo venting port of your new aftermarket BC solenoid - it reduces solenoid duty cycle.

2)Unplug it, otherwise you'd have two devices working in competition with each other and you have no control over one of them (factory one).

3)You can use this source, it's as good as any, but be aware of the fact that due to piping and IC core losses turbo will generate pressure that is 2-3 psi higher than you see at the spot marked on the attached pic. But the spot you marked has a benefit of giving you same exact boost reading your engine is seeing as opposed to outlet on comp cover.

I have both, ebc and gauge.

I hardly ever look when boosting, i look at the ebc after cos it has a peak boost memory, so you can see what pressure it made.

So the Autometer gauge is now a waste of money and dash space.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
