Hks Turbo And Bov


CTM508

Recommended Posts

After I changed HKS 2535 turbo on my AUTO R33, my idling down under 300rpm when I release pad~

It likes to turn off the engine

andthen it returns to 750rpm~

I feel that is aftermarket BOV (adjust) problem

Can stock BOV handle my new turbo or not?

Or any suggestion or experienced to share?

Thank all!

me thinks not could leak a little as mine did but i fixed it with a block of plate...atmospheric bov and automatics dont mix .get a larger full plumback bov that will fix the prob...think turbo smart make em

yer probs tighter.i was told once that a standard gtr bov is a fair bit better and is a straight bolt on to gtst... i just blocked mine of cause i was soo sick of the stalling ..it never stalled at high speed only like rolling but it robbed a f**k load of power

ive read alot about idle problems with aftermarket bovs, apparently having an aftermarket ecu can solve the idle issues, do you have one or is it just standard comp?

i have aftermarket bov.. and i got the stalling probs after i installed a pfc.. if its atmo then its cause ur air is reading wrong when ur revs drop.. start the car and let idle for a few mins and then adjust the throttle up a little 850 - 950 rpm and prob solved.. hopefully.. that was my prob anyhow..

+1 with Dan.

I'm running a standard bov on my turbo setup and idles correctly with PFC, holds boost at 15psi no problems at all and everything runs like a dream all day every day with 250rwkw.

I would suspect a massive air(boost) leak in your system somewhere. i.e. bov stuck open, intercooler pipe blown off, etc...

I did this and it works.

    • You won't make it out of your driveway. Both your rear wheels will go in whichever direction they feel. Your Hicas rack or a lockout bar is required to keep your wheels straight. 
    • Updating results.  Using ATR45SS-0 model VS UHF57-900. Those two are very different turbos, different wheels sets with different wheel hub profiles but yet with almost identical result. I’m intrigued with both turbos performance. ATR45SS-0 was a 61mm turbo first developed in May 2020, UHF57-900 was a 62mm turbo developed in March 2024 as a powered up alternative of a G30-900. On paper ATR45SS-0 maxed at 563rwkws, while UHF57-900 maxed at 568rwkws. ATR45SS was slightly more responsive with slightly better power band through the mid range.  Road driving ability, ATR45SS-0 had better throttle response, felt more robust under throttle, as it wakes up earlier. I think G series wheel hub design made it to have higher inertia under light throttle. Doing bit more prototype work in the next few weeks, will update result when its back on dyno again. ATR45SS0 Blue, UHF57-900 Red Chequered tuner's Dynapack hub dyno, E85 fuel. Mod list is in video below video_20240604_114214.mp4    
    • Did you run the power cables for the mac valve to the other side of the car near the fusebox? Utilizing the stock boost controller cables? or did you run new ones?
    • Hey I have a potentially stupid HICAS question 🤣 I'm currently doing a full hicas delete, Power steering pump modified to non hicas, all lines removed from the car along with all electronics. My stupid question is - Do I need a lock out bar? is there any reason why I cant just remove everything from the rear end? I already have a lock out bar but thinking to save a few extra grams I could also get rid of the arms and tie rods as well and just run it with nothing in its place? or would it have a negative effect on handling?
    • Hi how are you guys?  I know i have been absent for years but im coming back slowly guys just wondering if anyone know where the ball joint on the NISMO arm front and rear can be replaced with OE parts?  Also  i know this is not the thread looking for springs and blistein shocks for the 260rs.
