Car Makes Boost But Goes No Where

The car in question is my s2 r33 with 3076 and all usual mods to support it

this weekend installed Tomei poncams,big can 18psi actuator and changed the split intake plenum gasket

-changed thew gasket as it always had a small leak,

-changed the actuator from my garret 1 bar actuator to the big can for boost reasons

-changed the poncams and set them up at the same timing

Now the car is not its self. when you tap the accelerator theres a delay until it reacts, doesnt go anywhere, it makes about 15psi on the boost gauge by about 3500 but it moves like its making 20kw

we though cam gears could be out by a bit, but there spot on, we tightened the actuator, re did all the clamps and intercooler piping, not sure what else it is. it feels similar to how it did off boost but it doesnt want to go anywhere. checking the CAS timing tomorrow but for now any ideas before we attack it again tomorrow?

thanks

And you're asking all of this and you know you need to check the base timing before anything?

Why waste our time?

Check the base timing then come back and tell us there is a problem. Also, get a retune.

obviously needs a tune. but this feels different to that.weve installed poncams into a neo 25 and rb26 and both have run without these issues, will check base timing and report back

thanks

edit: also even removing the vacumn hose off the actuator the car acts the same

      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.
