Installation of Mechanical Boost Controller

Hi All,

I would like some tips on how to install a mechanical boost controller on a R33. I recently purchased the turbotech controller.

I know it goes between the turbo and wastegate, but I have been told that the solenoid needs to be taken out of the equation.

Does anyone have any specific instructions or photos they could email me on how to properly install this.

Thanks in advance.

Paul.

It's not too hard to install once you know whats happening? I fought with it for a week, but when I simplified it it worked fantastically.

With the instructions you got you can see the which connection should go to your wastegate actuator (the connection at a right angle to the controller screw). The hose that you need to run to it is the one coming from the turbo, look for the round bronze looking can-like item on the turbo, this is the wastegate actuator. Undo the connection, it's probably at a T piece which goes to the boost solenoid (that's where it was on my 200SX anyway). Then hook it up to the connection on the boost controller and use the hose clamp to hold it in place.

Then find (probably at the t piece) the hose that runs back to your intercooler piping. Hook this up to the connection that's in line with the controlling screw. Again use the hose clamp to secure it.

You will probably have a hose left over that was connected to the solenoid again, just block it off with a bolt that fits the hole and put the hose clamp over it so it wont come loose. Then you will be right.

As it says in the instructions the controlling screw should already be set at minimum boost (pretty much completely wound out). To increase the boost level just loosen off the lock nut and wind the screw in in small increments. lock down the nut again and test. Wind in or unwind the screw until you find the boost level you are happy with.

Hopefully this makes some sense. If you are still having problems check out the link below. There's quite a few pages on this controller there.

I done a similar method to PhantomS14, but I directly connected it to the intake pipe, then ran another pipe directly to the wastegate.  Throw the T-piece away, as well of course the factory solenoid setup.

Sounds like a neater set-up, however what confuses me is that the factory solenoid has two pipes connected. One from solenoid to the T-piece (this can be removed by blocking the T-section or using a straight joiner) the other from solenoid to the wastegate. Then the T-piece has also another pipe connected going to the wastegate and the other side to the intercooler piping.

Would it be correct to fit the controller between the intercooler piping and wastegate but then block the second wastegate pipe that was connected to the soleniod?

Sorry, a little confusing when putting a picture to words.

Yes.  You only need to block off the lower pipe that was on the solenoid.  Just put a wood screw or something down it.  

The upper pipe on the solenoid, goes where you threw out the t-peice and the rest of the solenoid. :rolleyes:

Thanks for the help, I will give it a go.

What about on a car that doesn't have any connections going into the intercooler piping like on my r31?

I am struggling to understand exactly why your plumbing it into the intercooler piping?

i got a turbotech and am going to put it on as soon as i understand where and why i am putting it.

From my understanding it needs to go between the wastegate and turbo. On the case of the R33 the turbo connection is via the intercooler piping. However I cannot comment on a R31 as I never seen this set-up.

Perhaps you could start a new forum discussion on "Installation of boost controller for R31".

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
