Ok so my r33 gtst is boosting at 11.6 psi... .8 bar and i dont have an aftermarket ecu, and i cant make the boost go any lower!! Mods: pod, cold air box, r34smic, 3" dump 3.5" cat back, and a turbosmart dual stage boost controller.

So am i right in thinking the problem lies with the boost controller? I heard they werent that great anyway... and theres no point in me having a dual stage when at the lowest setting its already over what i can run with no aftermarket ecu!

Anyone know where i can get a good cheap manual boost controller? and are they defectable?

Have you installed it correctly? You're meant to be able to set exactly the boost you want. Double check you've got it facing the right direction and all the lines are right, oh, and that you've set the knobs correctly.

Turbotech (ebay) make a great & cheap manual controller.

from what i know a less restrictive exhaust can be causing your spike in boost. my mate with a 33gtst had great boost control while stock - after he put on his hks superdrager.. boost control turned to shit.

if ur not planning on going for big power just get a ebc and get the stock computer retuned - something safe 13psi'ish?? will take care of ur problem and will make it safe to run that higher boost for not that much of a cost.

hope this helps.

Hey yeah all the lines are facing the right way and its installed correctly... the knobs are turned as far back as they can go for their lowest setting.... before i did the exhaust (had r34smic, and pod and cover installed) it was boosting at 10psi... i couldnt change it any lower... then with the exhaust now its 11.6psi wtf..

Then again, when the aftermarket boost gauge was telling me 10psi, the factory one was saying about 7-8psi...

i need to get it tuned... then they can test it and tell me wtf its boosting at :)

If you're after correct problem diagnosis, shell out a few bucks, get an ECU remap and dynotune at the same time. The following guy is realistically priced and knows his stuff:

If you do require a good manual boost controller, a Turbotech is the way to go. Make sure you have an accurate boost gauge before you start modifying boost levels. Don't rely on the factory one!

      Mistakes were made, my R34 Story

      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

      Jacks that fit under GTR lips that can reach the subframe?

      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.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
