Guys done the search but not a lot about pros and cons (just problems)

Can anyone enlighten me on what they believe would be the best EBC for a GTR running twin -5s. Max boost will be 2 bar.

I have been using a PFC EBC and am not happy with it so looking for an informed change.

Thanks in anticipation.

blitz dual solenoid boost controller and make sure its the spec r version not the spec s, holds well up to about 36psi, profec bs2 is good for the money but if you got the extra cash you can get the blitz spec r version, i think they are like $450+ or something but correct me if im wrong,

cheers tony

why arent u happy with the PFC boost kit?

you set the duty, set the boost and drive

what more is there to it ?

Yup that was my theory to. May have a dud as it will actuate (you can hear it working) sometimes and other times not. Wiring has been gone over and seems ok, solenoid fires on 12 volt, ..... Just lost confidence in it.

Rather than risk a lean out due to overboost if it does play up another unit seems a safer option.

profec B is good and very cheap. the blitz spec R and spec S are pretty average in my experience. the blitz SBD ID III is not bad though. but personally I still prefer the profec B II. I have it in both my GTRs.

here is my boost curve from some time back. if you can get a flatter boost curve than that, well done! also note how sharply it ramps onto boost, but still doesn't over shoot the target. very hard to get a controller to do that.

Im also looking for a boost controller and was deciding between a boost controller or a PFC (ER34 GTT) which is more feasible anyway? And do we need to have a dyno tune after the installation of the boost controller?

That line is almost as flat as my boost line in the gtr running of just the wastegates (no boost controller at all)

Nice :D

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
