when i first got my car i blocked off my valve and was running sweet for about 3 months, then i changed over my spark plugs then it started to stall sometimes and sometimes when the revs dropped from really high to idle. I just made it out to be a tuning issue but when i put new turbo and engine mods on and it stalls without fail every time if you don't keep fairly high revs. The guys that are tuning it are telling me that i can't block of my blow off and that i have to run it in order to stop the problem, but i don't want to do that. Pretty much everyone i know with a turbo has blocked theirs off, just wondering what could be causing mine to stall when i block mine?? i got an rb25 by the way.

This has been posted plenty of times - you should search the forums before posting.

Your car has an AFM. Your tuner was correct in stating that you can't do it if you want to stop the problem. Once the air has been read through the AFM and you release the throttle thereby closing the butterfly, the air returns down the intake pipe trying to find the BOV and recirculate. That is what it should do standard.

But you have blocked the BOV so the air goes back out the turbo the wrong way (or at least attempt to) and you get a stiffy as you flutter past teh laideeez and bro's (probably just the bro's) at maccas.

Problem is, your ECU has read the air going into the motor, but it hasn't and it dumps fuel in to keep the AFR correct. Thus flooding your motor with fuel and stalling.

There are numerous way's to get teh flutters without stalling, smartest one being geting a new ECU that runs a MAP sensor instead of an AFM. But since you probably wont...........you deserve the crap that you already have and will continue to get on this subject.

Good Day Sir!

Agreed, Air Flow Meter (AFM) is reading plenty of air going into the motor, adds fuel to mix, none of that air is making it to the motor, floods the motor...

How is your fuel consumption?

Sorry for the attacks, but it happens every time... you should have a done a search :P

Hope this does help.

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.

      "Cheap" bolt on turbo on RB25DET NEO

      By MBS206 · Posted

      It's funny, as Ive seen plenty of people use them in cheap builds on YT. And they actually go okay, even though a lot of other maxspeedingrods stuff is terrible. Those turbos seem reliable enough, the only part being, a good quality turbo that is "identical" to it, will out perform it day in and day out. In both a lower boost threshold, and the ability to flow more air at the same boost pressure. As a cheap cheap replacement, not a terrible choice. For cheap and shouldn't blow in a day, not terrible (like other eBay/Temu turbos) for low cost and still decent performance, that's where the question comes in to play from the results I've seen. I'd actually find it hilarious to buy one, and strap it to a paddock basher or some other cheap as POS originally NA car, and send it to the moon!
