What's the issue? Tune related?

Could be a number of things. It's not there to make epic power. I just wanted him to throw it on and make sure everything was okay. But if its losing that much power something has to be wrong.

Just made a phenomenal 160kw@ 9-10psi!

Obviously Shaun @ BoostWorx is fixing it.

out of a 26 that is definitely low power.....i know your not after epic numbers but still should be higher then that......pretty sure Shaun will nut it all out and let you know what is going wrong with it.....hopefully nothing major mate.....

A stock RB25 (flywheel 187kw) only makes around 140rwkw. A stock S15 (147kw) makes 114rwkw. My stock V35 (206kw) makes 146rwkw. 160rwkw for a stock, tired nearly 20 years old GTR sounds reasonable.

my RB20. 172kw > engine feeling sick > 110kw

Hope you get it sorted mate, but the extra 2psi its missing for whatever reason would counteract some of the difference...

Thats exactly what I thought.

No boost restrictor, front pipes, catback and pods should of surely opened up the breathing a whole lot more.

My last car had most of the things youve listed there, and it would run a whopping 4psi on "stock" boost. I needed a boost tee to actually get it up to the standard 7psi. Funny thing is, they had a boost cut at 12psi with a buzzer that went off in the cabin when it hit... I could get my guage to read around 11-11.5psi when it hit. It wasnt leaking boost, it simply just didnt run would it should have without help.

I dont know if wastegate actuators get dodgey over time or not, but this car was in the same age bracket.

I just had a thought, if the BPV(s) was leaking and recirculating back into the intake, could that cause it?

Maybe, but would it be enough to only take off 2psi? On the standard boost gauge I get to the line under +7. +7 apparently being 1 bar or 14.7psi. So I assumed I'd be around 10-11psi.

But when Shaun said it should be making atleast 190kw @10-11psi and 230-250 on 14psi.

He said it could be a timing issue or exhaust issue. But it could be a combination seeing as I've just got a compliance cat (bashed) and some thrashed out trust front pipes and dirty dirty dirty apexi pods. That surely isn't helping me at all.

Its suprising how much difference little things can make. I gained noticably more punch just by removing the resonator from my 3" stainless exhaust. - unfortunately I cant vouch for how much it was in KW, but you get the idea.

Ask RBWARE how much difference an exhaust can make to your power output!

Also, I dont think the boost stock guage works very well somehow :rolleyes:

Its 14psi man, and if it weren't my engine would lean out and go BANG! as I only have standard injectors. And the standard boost gauge represents 14psi where it hits and sits all day everyday

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must me missing something?

      "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.
