Quick Boost Controller Install Question

Hey guys. Just got around to installing my HDi EBC-R. I found a hole through the firewall for the hoses and cables and tee'd the boost line from the unit onto a hose coming off the intake manifold, but I'm a bit confused as to one of the solenoid connections.

The instructions say one end is to be connected to the wastegate actuator and the other end to the turbo. I found the actuator hose fine, but just not quite sure which hose comes off the turbocharger. I did some research and found some people connect it to the intercooler piping instead? Would that be alright for this case? I'm running the stock SMIC on an R34 GTT. Also, does anyone know what the top hose on the standard solenoid goes to? I traced it to a gold pipe with a bend in it located under the intercooler piping but not sure as to what it actually is/does.

At the moment, the stock solenoid looks like so with 2 hoses coming out, one of them tee'd:

_____

l l________

l _________ ???

l l

l l wastegate actuator

l l ________l l_____

stock solenoid l _______________ intercooler

l l

l l

l l

___l l___

So I guess my question is, instead of connecting the new solenoid to the turbocharger, would it be okay to connect it to the intercooler piping like some people have in other boost controller install guides? And also, what would I do with the top hose coming out of the stock solenoid? Block it off? Any help would be greatly appreciated! :P

Block off everything on the stock boost solenoid. Unplugging it might bring up an error code though so I wont tell you to unplug it, you can experiment with that lol.

If you have 1 side of the ebc solenoid hooked up to the actuator thats fine. Other side needs a pressure source, this can be off the compressor housing (u dont have one so pass...) you should have a nipple comming off an intercooler pipe or worst case get a T piece and T off the big vacuum line that goes to ur carbon canister and make that go straight to the solenoid on the port that requres a pressure source. There should be a pressure source somewhere in that area though.

Heres a pic of a greddy profec b spec 2 install diagram, will be same principle.

      Hazards not working R34 GTT

      It does sound like a fuse considering the indicators work..I’ll triple check when I’m free and report back.    thanks for the reply.

      no, the car was a manual 5 speed from the factory and still is.

      While going through data logs late last week, I spotted a small issue with my WMI. My WMI starts to progressively inject at 11psi of boost. I'm using a 25psi cut in pressure switch on my WMI as an added safety and if the curve is linear, I should hit that 25psi on my WMI system around 13-14psi of boost.  As per my data logs, my WMI pressure switch only activates around 19psi of boost. This is causing my non WMI 4D map to trim for WMI. I'm presuming this is caused by the mechanical switch response time, injection curve not being linear or both.  I ordered a 2-10psi adjustable cut in pressure switch which should correct this. If this doesn't resolve it before my dyno appointment on Friday, I'll just remove the pressure switch temporarily and more than likely replace it with a pressure transmitter afterwards.    BTW Speedtek has yet to refund me.

      Yep PETG (Polyethylene terephthalate glycol), my 'go to' plastic, printed to precisely how long I wanted 🙂, about a finger length ha ha. I would usually grind up something but since I've got the printer I thought I might give it a try and it worked beautifully ^_^b So with regards to torque, there's a little bit of science behind the orientation of the print, fill density, fill pattern and number of external perimeters which can increase the strength dramatically, but you still need to work within the constraints of the material and the orientation of the model for sure. I certainly wouldn't be making a breaker bar out of plastic, but this little bugger is very strong for it's size that's for sure.

      This is the part I was unprepared for. I mean, thinking about it now, the first day I collected my car from the importer someone posted a photo of it on the highway to an online JDM page which my friend then sent me. I drove straight to the office to pick up some things and was immediately swarmed by about ten college kids -  "how much power" "why no wing" etc. The next couple times I went out I didn't really notice anything, there was a "why no wing" at a service area at some point. Then during the fourth time out driving at the Nurburgring I got the "do a drift" - the bastard cut it out in this clip. The title in itself is a red flag. As you may have guessed, I am not a fan of the attention. This leads me to wondering what to do with the car in the future; I'll see how this year goes and it may be garaged, which it mostly is already, or maybe even sent back to Japan  to also be garaged and driven occasionally on visits. Fortunately my daily is as interesting as drying paint.
