do many of u have boost controllers. I was geting my car checked out at gavin woods the other day and he had about 5 skylines with blown engines in them, becasue of running 2 much boost. I was thinking about getting one, but now dont know anything about them. has anyone seen the sweet green gtr in there at his workshop, love the colour hmm maybe a respray of my car is in order.

My question is how much extra boost can u run on a standard line?. Also for driving around the street to save fuel can u turn the boost right down or even off? with a boost controller?

I have also been told they are illegal to be inside the cabin due to the fact u can change the porformance of the car so need to be under your bonnet or something, or u could just hide it under the dash i guess.

I use a HKS EVC IV and it is great. The auto calibration is fantastic. Two power runs on a dyno and its good to go.

You can save fuel by not pressing the right pedal too hard :( But that defeats the purpose of owning the line, doesn't it ??

You should call a certification engineer if you have any queries on the legality of anything. I know a good one, if you want the number send me a PM.

I've got an AVCR but as an electronic boost controller it still spikes every now and then, but not as bad as a gated one (ie, turbosmart).

My boost is set on 1bar (14.7psi). I run this all day everyday and it's been like that for about 6 months now. Normally the "safe" level on a standard series 1 turbo is 12 max of 14psi.

Depends on what your game enough to run.

My car is one of those there with a blown engine but it wasn't from the boost controller, it was from a failed cooling system.

Boost controllers are a cheap horse power spend and as long as you aren't running ridiculous amounts of boost you should be right.

Anyone have experience with the Blitz SBC units?

Ive got a Blitz Dual SBC sitting in my gagrage, was in the car for a while and then got an after martket ecu which will eventually control my boost and the next tune.

Good unit, holds boost well, occasional spike, fairly easy to use.

In re to the question (sorry for whoring) when i had my boost controller i was running 14psi all day, now am running ~12psi.

Have a Greddy profec B specII EBC , holds real well once you have it set right , and you can flick too hi-low boost all day with the touch of a button, so I have low set at stock boost ( 7-9 psi) and hi set to 11-13 psi but leave it on stock most of the time for fuel saving, oh yeah I got it s/h for $400 and I think it is around $600ish new

alright well some food for thought thanks for all your help people. Now the question is do i wait till im on my opens which is in july, i think i will lose my licence with the normal boost rating anyways so might as well up it to 12 lol. Thanks again

Which dual SBC is it (spec R, spec S, DC)?

most are fine.... and have various advantages and disadvantages. Some are slightly better than others, but when it comes down to it - the boost controller is just one part of a whole system. If you do something stupid you can kill the car, so yes I guess they can be a bit dangerous in the hands of somebody who doesn't know the various ins and outs.

I think you QLD'ers must love blowing up engines, and seem to think just winding up the boost to 18psi is a great way to get more power :P

do not run more than 12psi on a stock ECU r33.. .

do not run more than 10psi on a stock intercooled r33..

maybe you can for a little bit but over time, something go bang, wallet go bang, fun of owning a turbo car out the window.

So what is needed to run boost up to 15psi?. I understand that the weak points of the rb25 at high boost levels are the pistons, head geasket and intercooler. I have a dual stage boost controller and the second stage is not yet dialed in. 1st stage is set to 9psi and have been told to go ahead and set 2nd stage to 15psi. The engine was rebuilt recently with (among other things) forged pistons, thick steel headgasket and has a large intercooler. Is 15psi reasonable?

Is it the standard turbo? If so i wouldnt be running 15psi through it.

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
