Electronic Boost Controller Installation

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.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      R34 power steering

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      By Kinks · Posted

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy

      Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
