hey guys,

have just installed a Speco boost gauge and Turbosmart boost controller (bleed valve) on a 1993 R32 GTS-T today. when we took it out for a spin boost gauge reads 14psi with the controller turned all the way down. it hits 14 then slowing creeps back down to about 10psi when rev's get higher. we pulled over and wound it up 5 clicks and still hits 14psi but quicker and still creeps down to about 12psi. have i installed everything correctly or could it be faulty parts?? anyone had this happen before???

cheers

its common that your boost does fall in higher rpm. it could be many reasons. such as bov, intercooler piping, silicon joiners, intercooler and anything else related to boost pressure. i am having the same problem and i beleive its the stock actuator. so i will be upgrading to the hks adjustable.

Ive got a manual boost controller and this doesnt happen to me, I reckon uve installed it wrong

the only thing i could have hooked up wrong would have been the boost controller! what will i notice if i hooked that up the wrong way? i might switch the hoses to see what happens....

if its hooked up the worng way u will have full boost all the time, which way does the flow arrow point on ur boost controler if it points towards the actuator its right i think from memory i havnt looked at mine in a while. when i installed min ei could only wind it down to a min of 10psi cos of the exhaust apperently when u get a free flowing exhaust ur boost will creep up a bit

Yea that is possible, but its also possible to hook it up wrong so u stay on stock boost, trust me, it happened to me once

turbosmart boost controllers have a habit of boost creep. Just get yourself a TurboTech off this forum or eBay for under $30.00 and never experience boost creep again..

I'm running 14PSI all day, and I've never seen it spike.

      It's the same ABS unit from the old shell.  It was all just lifted and shifted.  I am looking at the BMW MK60 ABS unit as a budget upgrade, as I'm not keen on handing over 15k for a Bosch unit.

      Bear in mind RBs tend to be pretty terrible for fuel economy and it heavily depends on driving style. In my experience with a heavy-ass turbo Stagea the 10l/100km is really just ideal conditions highway driving. Start-stop in the city is killer and it ends up being 16-19l/100km easily. I keep track of it every time I get fuel and it is never pretty. There are a few topics in the forums where people share their fuel economy if you want to get some ideas of what it can be like. I don't think it is worth that much to compare though because it depends so much on the driving.

      R32 GTR Limp Mode?

      R32 HICAS, so long as the CU is not itself faulty, is easy to keep working enough for the PS. Just unplug the smaller of the two loom plugs, on the CU, like I have already said about 4000 times on this forum. This works with all the stock hardware, or with a lock bar, or with a complete removal. I know, because I have done all of them. OK, actually, I never put a lock bar on because why would you put a lock bar on when you can get rid of the whole lot, including the stupid tie rod ends?

      Join the NorCal facebook group btw, but if you can confirm it is HICAS I would install a lock bar and do the work to keep the HICAS control unit happy despite the hardware not functioning. The HICAS control unit is also responsible for speed sensitive power steering so if it's unhappy you'll get failsafe/heavy power steering. A standalone can control that power steering solenoid valve but sometimes it's just easier to stick with the factory setup. Tomei makes a little electronic module that you can install to fool the control unit. I would probably go through the effort to not use a scotch-lok and build a harness so I don't have to chop up the OEM harness. Where you could source those connectors and pins I wouldn't know at the moment though.
