just been reading a bit about the -5's.

ive got the -5's + usual supports on my RB26, standard internals, running profect b low boost 15lbs high at 18lbs 320AWKW, reading what nismoid said that the-5's really start going around 20lbs, i was thinking about uping the boost to 20lbs, as i feel the -5's are not even trying yet. can anyone tell me is there a much difference between 18-20lbs? or should i head towards 21-22lbs to quench my boost thirst?

cheers

Being you have a stock motor, you've gotta ask yourself...

Can you afford the rebuild if it lets go? :)

On a built/prepped motor you can make 380rwkw around ~20psi (see Snowman RB26 dyno result)... A stock motor you gotta be prepared to throw the dice.

hmmm yes nismoid, just going on what a few tuners said that its not so much the power (though im sure 380AWKW would kill an engine pretty quick!!!!!!) that will kill the engine, but high revs, and or a poor tune.

im just not realing feeling the 320AWKW, so was thinking to move up to 20lbs, safe tune, bring the rev limit from 7500rpm, to 7000?

was thinking the extra 2lb might be what im after?

ps. running a G4 LINK, no AFM's

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
