hey guys i dunno if any1 has suggested this yet but i havent spotted it, what i did on my old s13 was when i upgraded to the s15 turbo i just whacked on a sard fuel pressure reg, and then my mate did the same to his r32 with an r34 neo turbo. up the fuel pressure a lil bit and gives ur cylinders the extra squirt u need for the more air ur inducting, the more boost, the more fuel u can run, will cost shit all to put on the dyno to check uv got the right afrs'

Shouldn't need a fpr, aslong as the fuel pump is in good order the ecu will do the rest. You generally want to trim a bit of fuel out anyway which is why people get SAFC's for minor mods instead of a full tune.

P.S. my last power run cost $70, not a big cost to make sure your afr's are alright..

+1 spend 70$ and get it checked on the dyno

stock ecu's can be strange things , lean when they should be rich and vice versa

btw i read the dyno upgrade thread but unless i missed it no one on there posted results with a neo turbo? plenty of rb25 s1 and s2 though.

Would it be unreasonable to ask for 200rwhp on a build like below.

R34 Neo turbo

My RB20 with stock turbo made 200rwhp at 14psi, with series 1 RB25 at 12psi it made 245rwhp.

I would expect an RB20 with a Neo turbo at 14psi to be making somewhere around 260-280rwhp.

oh coolies, would be sweet to actually make that much power out of the little 20 hehe.

      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.

      Lock up the old for sale / wtb threads.

      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.
