my car hits 14-15psi at 3000 but drops back to 10-11 at redline. pod, fmic, nice big intake piping, turbo-back exhaust. turboxs bleed too. i'm considering a different actuator, EBC or autospeed boost controller (altho i doubt it would hold it any better?)

I tested out my boost holding capabilities last night, it seems to hold 15 pound, but does drop off to 13.5psi or so somewhere high i the revs.

It is hard to watch the boost gauge, tacho and the road at the same time hehe

I will try and get the datalogging going and see if I can get a read out some time this week

Hi Dean,

Hope you are well. Pricing information as requested:

Cool - that would be nice :)

I think 0.8 - 0.9 kg works out to be about 12-13psi isn't it ??

That's pretty good, and pretty much smack on what I'm looking for. I suppose if you were really keen you could bleed off 1-2psi to get to 1 bar. But at least you would drop boost like I am :D

when i get some money ill let u know how it goes.

Does any body have any info on the wastgate actuator for R32 turbo ive heard it doesnt open til 10psi.

Is this true?

Would it fit in place of the r33 item?

Anybody else done this?

HKS one is cheap enough but im not keen on running 12 - 13psi with standard intercooler/turbo. Plus anymore the 10psi and my engine seems to ping on hot days. Gets to over 40 deg there in Horsham.

Hi Munna

Is this true?

**Yes

Would it fit in place of the r33 item?

**Yes

Anybody else done this?

**Yes, many times

anymore the 10psi and my engine seems to ping on hot days.

**You have a tuning problem, too much ignition advance or too little fuel. I strongly suggest you get it tuned properly.

Hope that helps

Dean: I found that boost drop on the standard turbo was caused by a combination of reduced ignition timing up top (which reduced combustion pressure and exhaust flow) and the turbo being unable to flow any more air because of high back pressure and cylinder back filling at high rpm. The Vg30 exhuast housing with no other mods on the Rb25 turbo held 15psi to redline. I actually locked my wastegate closed and my RB25 turd and it still still didn't hold boost.... hope that helps

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.

      Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender

      I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
