Hey guys,

Ive had these turbotech boost controllers on heaps of cars, including my current S14 200sx which was solionoid controlled just like the R33 etc.

Now on my R34 ive tryed hooking it up as all i want is the boost to come on sharper not actaully run anymore boost like normal but it wont work, all it dus is make the boost go more and hit about .8kgcm2 which i dont want to run!

The car has a Blitz catback and apexi pod.

Any ideas?? COME ON R34 OWNERS HELP ME OUT :D Im sure theres plenty out there using these yes...

I have wound the spring right out as far as it will go and it still wont boost any lower...I wound it right in (dumb but still no change)

It boosts fine when u run it back stock again :D

THANKS for putting up with yet another turbotech boost controller thread

Cheers,

tried backing off the bleed valve?

Yea ive dun all that, i dont understand how PHYSICALLY how it can not work now lol..

thanks tho mate

Any R34 owners have pics of their setup...

I found that if you plug up one of the vaccum lines from the solinoid it stops the boost gauge from working

one side of the boost controller should be connected to the pipe coming off the elbow right off the turbo which leads to the intercooler.....the other connection goes to the wastegate actuator....... the tpiece and hose from original solinoid u dont need and the other vacuum line which leads to a pipe can be blocked off. Also check the boost controller...wind it right out and check the spring and ball are free..... i had an issue where the spring got stuck in the thread grooves of the unit hence even with the bolt right out was making high boost.....hope this helps......a pic would make it easier.....

Thanks guys, ive taken a pic of how its setup..

I took the spring out the controller and pulled it out a tad.

It boosts a bit lower now but still with the controller wound all the way out it boosting an extra 1-2psi.... very odd from my experiances with these.

how much boost are u running? 10 psi? if thats all u want to run get an r32 wastegate actuator, they are set to 10psi, replace the actuator that the r34 has, they are the same, and then just run a hose froom the cooler piping to the actuator.

done, 10psi with no boost spikes.

Thanks guys, got it all sorted, ripped the controller out again and the bal was infact stuck.

Running 7psi now, i just wanted to get that boost on a little quicker. Its alot better when it comes on boost now and dusnt need as much foot or fuel to get that driveable torque thru

THANKS HEAPS FOR THE REPLIES GUYS

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
