i have the bost controller as above and ive noticed that if im fully fanging it (like we're talking fullthrottle top end of 4th and 5th on high boost, the little plastic plugs that come with it to block the one spare hole in the solenoid pop out and it starts overboosting, i even tried siliconing in one of the plugs but now all of em are popped so i cant run high boost until i block this up, no screw came with the kit to block it up which is stupid and the tyhread seems to not be of standard thread types for that size screw, wtf can i do ?

no because when the plug is in i get no overboost, but when the plug pops off i get overboost, because it creates a leak in the solenoid, dunno wtf is wrong with your boost controller then dude coz if u have a leak u should be overboostin

I dont know, mine had always run with no problems without the little plug for the 3rd port.

i dont actually have it connected atm cause i have an adjustable actuator.

hey sorry to post this up so late.But ive had a problem with my boost ever since i got the above boost controller installed and i just found out that the vaccum + pressure lines swapped the wrong way (with the actu8or hose where the preassure should be and vice versa) so i was getting a suck reading where i should have been getting a push reading to the valve unit.HAS THIS HAPPEND TO ANYONE BEFORE AND WHAT DOES IT DO TO THE OVERALL PERFORMANCE OF IT BOOSTING ETC.?????

      Is it alright to top up with just another green coolant?

      thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
