Hi guys,i wired up my new electronic boost controller to my r33 but it is doing nothing at all car just boosts until turbo chokes.ive got a vacuum line coming from the line between the fuel pressure and intake manifold to the boost controller and to the soleinoid ive got the line from the actuator and line from bov return hose going to the solinoid it says to have the line come from the intercooler piping or turbo housing would that make a difference? Any help would be much appreciated

The actuator needs a pressurized line, the bov return is not what you want, you've essentially got two vacuum feeds. You want to get a feed from as close to the turbo outlet as possible. I've got mine coming from a brass nipple tapped into the hot cooler pipe just after the turbo.

For a start you havent listed what boost controller your using which would have made it hard to help if you hadnt already listed the soloution to the problem. The return hose from the BOV will have no boost pressure in it while the throttle body is open (ie making boost) so therefore will not activate your actuator to control your boost

if the book says to get the feed from the intercooler piping or turbo housing, and your getting the boost feed from somewhere else, do you really need to come on here and ask what the problem is

Incase you are talking about the boost/vac line to the top of the blow-off valve then that should work but is not ideal, much better off getting your feed from the turbo side of the throttle body not the manifold side. If this is what you meant then you may have the lines on the solenoid back to front.

Ok cheers im putting a nipple in the intercooler piping so hopefully that works :) do I block off the bov return line?

*sigh*

BOV has nothing to do with controlling boost, leave the BOV system how it is (assuming its all working fine)

If your talking about the small VAC line that runs from the steel BOV return pipe to the standard solenoid then yes block this off

If your talking about the small VAC line that runs from the steel BOV return pipe to the standard solenoid then yes block this off

Hijack..

What is that thing for anyway? I have an EBC that needs to bleed pressure build up between the actuator and the solenoid - can I plumb the bleed back into that?

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
