Has anyone used a pair of S15 turbos in a GTR or anyother car using an RB26?

Just thinking since these regularly make 180kw on S15 that they should make 300RWKW on an RB26 pretty easy.

If i am wrong please let me know, the aim is to make 300RWKW by doing the following

Injectors

Fuel Reg

Fuel Pump

Computer

Fuel Pump

Intercooler

S15 Turbos x2

Would i need do to the cams aswell???

people with sr20det silvias can sometimes squeeze out ~210rwkw with cams and such with these T28's, its what the silvia community consider to be a step down from HKS GT2530's, which most find to give them around ~230rwkw

IMO it wouldnt go too badly with with an rb26dett, you wont make as much as twin gt2530's, but you will probably have better down low and mid range... also cost factor, as these turbos can be had for around $1200 new and going for as low as $700 for good condition second hand one, it makes it a good option

though they run a T25 flange, so custom manifold is needed

there was a thread on here somewhere about this

apparently the rear turbo will foul on the engine mount and require mods to fit

i think water and oil lines are in a different position and the compressor covers are larger

pretty sure flanges bolt up though

lots of other easier options out there

      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.
