then again i see you have 300 plus rwkw standard internals?

nope my motor is now fully forged pistons, rods cams etc u name it its got it....300rwkw on just 17psi

built by Willall Racing, Nisspeed, and tuned by Morpowa

i asked Boostworx who pays for it and they said i had to at my own expense, they really didn't care to be honest, im sure im not the only one here that has had grief with them....i guess im the first to speak up.

Your manifold, while it looks like its a pro job with the cut and shut, is a really really bad idea,since the runners are designed for air coming in at the normal throttle position, now you have the TB at the front... this means cylns 5-6 are less likely to get the same amount of air.

if you had the manifold on the motor when it blew up, i dare say it could have played a huge part in it.

i guess i got another reason 2 blame boostworx 4 blowing up my motor because they are the place that did the cut n shut!!!!!!!!!!

Who wanted the manifold like that??? Simon isn't saying the cut and shut was the problem, Think about where the inlet pipe goes standard........... In the middle, this is to make the air get dispenced evenly and appropriatly, not a crap load at the front and stuff all at the back!!

Just an update - I ended up going to Morpowa, glad I did as they sorted me out nicely. It definately needed a tune, cruising was fine so no problems with the O2 sensor, but the AFR's were for some reasons in the low 10's. We weren't quite sure why, as the car hadn't really changed since the last tune apart from a different catback Exhaust (still 3").

Regained 20rwkw with the new tune and hopefully this will fix the fuel economy issues.

    • 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.
    • 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
