Guys,

After reading many threads and trying to find out how to connect my boost solenoid back up, i have done it but just want to ensure it is correct.

It was setup to bypass the boost solenoid l(hose from top nipple to bottom nipple) on the solenoid.

Below is a pic of what i have done, is this correct?

Any feed back would be great!

Also, While i am on the subject of boost solenoid's, is there any benefit of using an R32 GTR boost solenoid on my R33 GTST?

I was using it on my VL i used to own!

That looks correct. From the aluminium piping it goes thru the T piece to the turbo actuator. The T'd off pipe goes into the solenoid (as you have it) and then the other side of the solenoid goes to the intake pipe (ie it bleeds off pressure that the actuator see's.

Not sure if its std piping from alu pipe, but note that you need to have the restrictor inline between the T piece and alu piping.... else it wont work.

thanks fastrotor,

i ended up trying it on sunday anyway, its all good. The restricter must be in there as it is boosting correctly, 5psi then 7-8 @ 4500 and when the solenoid was bypassed it was hitting around 11-12psi. Feels alot more responsive and smoother now than what it was just bypassing the solenoid, just not as quick :P

Looking at getting a profec b now so all is good.

cheers mate

Glad to hear it all works ok mate. You could also look into a plug in computer that does boost control.... save spending money on both !

I use a link, and it allows you to program what boost you want at what revs. This is great and once setup, works great. I run 11psi on mine and at about 6000 rpm + i roll the boost off to 9psi.... i did this as on the dyno it would nose over in power...... so regulating to a lower boost keeps the wastegate open instead of closing and trying to mantain a boost level thru a small housing...... thereby extending your power curve due to keeping the turbo to motor backpressure lower.. So instead of dropping power at 6500 rpm i lowered boost and it maintained power to 8000 rpm !

Some helpful hints hopefully

good stuff.

Its all about sweet talking the missis. They want a house and we want 600HP, haha

baby seat fits great in the back :rolleyes:

Haha, thats ok, i know what you mean. Im doing up the house currently, and ontop of the skyline i also own an rx-7 ! Both worked alot !

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
