HI,

Just need some opinions and experiences of you guys.

I'm replacing my turbos due to my turbines ending up in the cat. I have two options and needing your help to choose.

1. R33 GTR turbos freshly rebuilt with N1 internals for $1450 comes with 12mth warranty.

Specs: 360 degree Thrust bearings

VSR / Hi Speed Balance

Nismo / N1 41.7 - 53.0 Spec Steel Turbine

Pros: Can be tuned upto 300KW ATW, $1000 cheaper, relatively low lag similar to stock ones

Cons: Don't know anyone thats had these and experiences, bush bearings, and pretty old tech turbo.

2. Garrett 2860-7 brand new $2400

Pros: New turbo, ball bearings, tried and tested and sworn by many modders, hardly any lag

Cons: $1k more expensive

Now I'm torn between these 2 as I'm aiming for around the 300kw and both are supposed to be able to do this. It will be a daily driver and will only see the occasional track maybe once or twice a year if that. I don't usually hoon around town with only the occasional spirited driving.

My main concern is responsiveness, and top end power will always come second to that as I will hardly be opening her up that much.

The delema is the $1k difference in price tag, and as you all know swapping turbos over can be an expensive job. Will the N1 spec one give me what I want or am I just wasting my time and money going down this route? Upside is if I do this, I can spend that money in tuning time with the Power FC (which has not been installed yet). Will I get a noticable difference in performance?

All thoughts welcomed

I'd take the -7s. they will make a little more power with a little less lag.

Unles the difference in price is a big deal of course. the 33 n1s are OK but older tech, bush bearing etc. $1k probably isn't a lot in the total cost of modding one of these. Another option might be 34 n1s they are ball bearing.

BTW I run the r32 n1s due to race rules and they are OK with a bit of work - but newer BB turbs are a better idea.

      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.
