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

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
