with std intercooler youre best setting the boost to 10-12psi. so what youve got it at is fine. any more and the exhaust wheel will d/c from shaft and end up in your exhaust pipe

if you want more power get an AFC (air flow converter) such as the Apexi S-AFC. make sure you have a better intercooler b4 running more boost. (std is very inefficicent) if you have the right fuelling and management, the RB25 can handle over 300rwhp, but your turbo will die before your engine

We have someone from here that is running 300rwkw with the stock bottom end.They havnt blown it up yet.

With your new turbo,H/Gasket you will also need an aftermarket ECU aswell as injectors,fuel pump,fuel pressure reg......

When all this is done make sure you go to a good tuner cause they will make or brake your car.

hey Bugalugs just asking who is this? what mods has he done and how long has he been driving it like this? i dont think the engine would be able to last long with that level of wear and tear? (correct me if im wrong)

Mods-I dont think this forum has enough space to list it all.Its the GTST in the one of the Speed magazines owned by Danny from JMS.I watched it do a 296rwkw at a car show.He drives his cars hard(i know,ive chased him).

Its interesting that you say the stock bottom end wont handle the power.I just havnt read or heard much on ppl breaking motors cause of the bottom end,its always other things that have caused the problems.

Maybe someone can correct me if i`m wrong.

Anyway its a NISSAN it dont break!

Have been told by one of the performance houses over hear that the best 'reliable' hp you can run before needing to start thinking about going to forged pistons is about 350 rear wheels. Not sure if he just wanted to sell pistons, but at the time the conversation had an emphasis on reliability to the point of being able to run all day every day

    • The cross sectional area of a circular hole scales with the square of diameter. So a 2mm diameter hole is 4x the area of a 1mm hole. Not double. The 1.7mm hole is nearly 3x the area of a 1mm hole. You do not need restrictors at both ends of the oil supply line. If you have new, additional restrictors at the turbo end, that you did not have before, then you do not need a restrictor at the inlet end.
    • 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/
    • 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.
