Have tried to search mutliple sites for any answers on the following question, but all came up negative :)

Anyways, purchased a dual stage boost controller second hand, it just included the controller and no other wiring of T piece, but i have hooked it all up and included the rocket switch in my cabin and changed all the two dials (turned them up all the way) and i still cannot change my boost setting.

Will include some pics of my setup later tonite but just wondering if anyone has installed one of these and have had this successfully working as i cant seem to get it to work at all

Basically i have hooked up cut the vacuum hose between the nipple of the inlet pipe coming off the cooler and the hose connecting to the acutator. (this is the only hose i can find) and put a plastic T piece in there and run that to the boost controller.

The boost controller only has one nipple so that i can put a hose onto it, which seems strange.

I can only think of a couple of things that could be incorrect.

a) Hoses are incorrect somehow.

B) The plastic T piece is incorrect (The turbosmart one has a arrow on it and could have a restrictor inside maybe).

c) ......

The boost controller works fine cause when touching the wires together on the rocket switch it will click on and off so i know this works fine.

But can anyone help me with the setup on this.

dude! I dont know how much of a help ill be with this but I had a dual stage with a similar prob on my 34 - didnt seem to have any boost but occasionally if I flattened it the boost would kick in (wasnt stable though)

Turned out there was 3 hoses going to the stock one - the actuator part was ok but there was another hose (dont know which one sorry) that was connected that shouldnt have been, and it wasnt blocked off when it should have been.. a mate looked at it for 2 secs and connected the other one, blocked the unused one off and it was perfect after that??

dunno if its any help? sorry if it isnt!!!!

You need the T-peice.It has a small hole in it which you need so when you bleed off the air to raise boost.That T-peice is also gated for faster spool up.I had major spike probs with my single stage!!

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
