hey guys i recently put in a manual boost controller in my rb20 32, and looking at my boost tacho boosting to 12psi is good, happy with response etc, but as i turn up the boost to say 14-16psi the car feels like it doesnt move and has trouble boosting, no G force whatso eva.....

btw. its got turbo back 3" exhaust, FMIC, pod filter, using motul 4100 oil and standard ngk plugs

any ideas?

Factory boost cut/fuel cut. I put a turbotech in after Christmas and same thing happened, at 12psi wouldn't rev all the way to redline. I went down to Mercury Motorsport, they said it was easy as to tune out, so I am going to get an ecu remap with them once I have put my intercooler in.

Til then I have just wound the boost down and staying away from redline as you can't be sure the air fuel mix is safe anyway. I'm not 100% sure on what actually causes it - You may be able to just get a fuel cut defender, but its probably worth getting a tune. My view is that unless my car is tuned to make use of all the mods I have done, I've just wasted money on buying them.

Regardless, I wouldnt recommend running over 12psi on stock turbo, unless you're happy to have it die. In that case maybe it isnt worth tuning til you blow it and upgrade to a high-flow or aftermarket.

      Ball bearing turbos

      By sunsetR33 · Posted

      Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist

      There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/

      Forced Performance Hta Turbos

      Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.

      Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.

      Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers
