Exactly. 700hp front, with a 450-500hp rear...

not optimal at all regardless of what results you wanna quote.

A 3071 would almost make the same power, but with a noticeable improvement.

Hi there. Im currently running a 3076 with 0.82 rear. This was initially on the stock manifold which basically would not go past 290kw. The tuner even tried going up to 23psi which resulted in no power increase. So left it on 19psi. The only change since then has been the install of a S-tec manifold which is still low mount and the end result was 18psi at 300kw. Not sure what this manifold would be restricted at but from what i've researched they are said to be good for around 340kw ish. My tuner did not even try for more as he said for a stock motor that's all he want's to push it to. So for me the S-tec low mount manifold is perfect. It is 321 stainless, fit perfectly and was finished off very well. It has been on the car for around 6 months now with no dramas and cost $450 delivered from Japan.

its a .82. i got some overtime in work so im just going with the raw brokerage manifold. i would like to get the best spool time out of this turbo as i can. and stop with the 3076 comments. im not going to switch to it, if you guys like it thats fine but i already have the 35r. heres a link to the manifold. the only thing i am considering doing if its going to be to my benefit is getting the t4 twin scroll ex housing instead of the t3 open that is currently on it..

are you just getting that cos it looks awesome? (note i am NOT questioning the quality) 6boost was $1250 shipped in under 2 weeks and they look pretty good too... if you do have problems it would be much easier for you to work with kyle than with someone in the us

lol sorry i live in the USA thats exaclty why im getting it. not cause it "looks cool" ..... 6 boost is harder to find over here. i get a lot of my parts for my RB over there they are a good place to deal with.

And then when an aftermarket manifold is fitted and he wants to make use of the built engine he's got nowhere to go.

I'm running 288rwkw on stock manifold with gt3582r with 0.82 housing and full boost @ 3800 on 18psi

doesn't sound right, that's better or equal to a 0.63 housing

If it is right thats close to my 30e that has full boost at 3600, making 303rwkw @ 17psi on an ETM manifold. Sounds a bit early to me?

      Rear subframe stay bracket bolt removal issues

      By DatsunBanana · Posted

      Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 😅

      Question about BoV on RB25DET NEO

      By Dose Pipe Sutututu · Posted

      BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 🫠

      Question about BoV on RB25DET NEO

      By Yeetus · Posted

      I've tried all different combinations of BOVs/ no BOV and stock bypass valves over the years, on gear changes the stock bypass valve seems to get the car back on boost quicker because in part the turbos wheel speed isn't being slowed down by reversion, although they have issues holding boost much over the stock setting. Most aftermarket BOVs you can adjust the spring, tighter will make it open later and close sooner, but in my experience it'll cause a bit of flutter at low load/rpm anyway. I've also got some input into this whole no bov causing turbo wear, never had an issue on any on my turbos HOWEVER, I got my R33 GTST with 200k kms on it, with from what I can see still has the original turbo, no lateral shaft play but has about 4-5mm of play in and out which to me seems like a worn thrust bearing from years (100-150k kms?) of turbo flutter running no bov, so maybe there is some truth to it in the long run. But that'll never stop me loving the Stutututu while I have the car.   OP just wants to know if he can run a atmo vented BOV with no major issues and the answer is YES, plenty of people do it, there's no harm in installing it and seeing how it runs before spending $$$ on an aftermarket ecu, last time I bought a Nistune it was $2400 for install and a tune , unsure of todays prices but you get me. Crazy money to spend just to fix the minor inconvenience of stalling that can be overcome by letting the revs come down to near idle before putting the clutch in or a little bit of throttle to avoid it. You're better off leaving the ecu and tune for after a bigger turbo/injectors have been installed to take full advantage of the tune and get your moneys worth.   Let OP have his Whoosh sound without trying to break his bank haha

      I see you missed the rest of the conversation where they have benefits, but nothing to do with avoiding breaking turbos, which is what the aftermarket BOV made all the fan boys, tuners, and modders believe was the only purpose for them...

      But they do so for the other reasons to have a compressor bypass. It's in the name.
