Hey everyone, had my R32 GTR for a few months and ive decided to upgrade turbos.

Now before everyone starts telling me to go look at the RB26 turbo upgrade section i already have and it didn't really answer my questions about what to choose.

Current turbos are rebuild stock turbos with steel wheels (possibly only exhaust wheel is steel and intake is ceramic) and they have been hi flowed. They 360drg thrust bearing (not ball bearing), Turbos came with the car the previous owner got the turbos done. All Supporting mods are fitted aswell as adjustable cam gears(according to previous owner tuned for response) and cold air intake with head shield. Car runs @18psi, reason for upgrade is i want better response. Car pulls nicely from about 3800rpm but doesnt make full boost until about 4700-5000rpm (rev limit deduced to 7500).

Not looking for any extra power car makes 280kw and i dont want to take the stock motor much further. All im looking for is the turbos that will come on tap as early as possible and also maintain torque and power throughout the rev range. Currently torque drops away at 4000rpm from 480nm to 350 by rev limit.

These 4 sets of ball bearing turbos in the title seem to be the most popular for what i want out of them, how much of a reduction in spool time should i expect to see with ball bearing turbos? which ones would everyone recommend for everyday driving @18psi? Is it worth replacing the stock dump pipes for full 3" ones?

If i need to give any more information tell me and ill answer best i can.

Dude this is covered in depth in this thread here:

(not just the dyno results)

From the very first post you can see which turbos are the ones you want.

Before I close this, as honestly the thread has covered this 20 times over… I’ll tell you as well…

R34 N1’s is what you want for 280rwkw and blistering response.

No car will hold torque forever, however they are the single best choice for your power goal

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
