So... I've kinda been on a hiatus with the stupid car/build. Thought about stripping it and buying a Golf GTI or R. But I hate euro tax, I hate that I can't tune the car myself, I hate that there are no plug in aftermarket ECUs for those heaps of shit, the hate list goes on for a while. I am not happy with paying someone wanker $1.2k for a bullshit "flash tune" which I know comprises of nothing special. So yeah, JDM revival time betches!

So ended up selling the old block but kept the sump. Upon removal it looked like someone had throw glitter into the motor lol. At least it lasted, and defied all Internet belief that you can't run more than 1.3bar on a stock RB25.

During my downtime, I may have purchased this:

And because I want 400kW now (for internetz credits, street cred and my sheer hate of VW tax) I bought some wanky Tomei 260/9.15mm cams and ARP head studs. Contemplating if I should pull off the head and replace the head gasket, do the valve seals and also install new valve springs.

Time will tell, after all this shit box has been off the road for 5 months now and hopefully once she's back on the road she stays on the road and not broken.

More to come..

Yes to fresh head gasket at the very least while you can do it easily. Also homo coolant/vac hoses etc.

Springs wont hurt given the boost you will want for 400 wasps.
 

 

 

Ahh fuark.. just also ordered:

  • Performance Springs - 85lb Valve springs & Titanium Retainers
  • GKTech Camber Lockout kit
  • A bunch of seals and shit to reseal the motor8

sure will, won't disclose too much information about the turbo (as I know Tao likes to keep the specs away from the internet).

But here's the exducer measurement of the compressor wheel. Note it's a 6+6 blade top, so will dose till the cows come home :)

Mine might be a touch laggy too as I've decided to put some 260 deg cams in. Being a NEO I'm also planning to spin it to about 8k rpm to have a decent rpm range to use.

Wish me luck LOL.

However always tricks to get it on earlier with either lean spool or pull timing as it comes on.

Yeah looks like I'll get the Nitto pump, it's only a bee's dick more than the Spool spline billet gears and a N1 Oil Pump housing.
I was trying to make the motor bullet proof, and that means rev limiter abuse proof like 1JZ and 2JZ, but I've read that the poor harmonics of the RB crank itself is enough to cause the crank snout to move and exceed it's normal circular travel cause any form of spline driven pump to misalign and go chomp. "Apparently" through Facebook whispers Nitto did the whole spline drive thing and abandoned it because it worked out more reliable keeping that Nissan oil pump drive style.

Went done the spool spline gear route. Wish me luck!

Sietbok updates, starting stripping down the RB25DET neo AWD and found out that the RWD sump bolts up to existing pre-tapped bolt holes - woohoo! Just need to cut and shut the pickup has it site further forward due to the front diff.

Will be sending the sump off to Spool Imports.

More to the less exciting shit, spent the better half of Sunday pulling off the manifold, turbo, plenum, etc. so that I can rip off the head. Everything was going well, till I stripped a allen bolt, brilliant! Called it quits after that also made a massive mess when the bolt stripped and the stand shook, sloshing oil all onto the shop floor. 

What a shit weekend, lucky for someone they scored a free front diff/sump haha

    • Before all the EFR fan boys come in, have a look at: https://www.garrettmotion.com/racing-and-performance/performance-catalog/turbo/g-series-ii-g30-825-58mm/ It also comes in a T4 1.06 divided housing. I would dare say if you want response & also decent power, this thing would chop.   AND apologies, just re-read your post, you've already bought the turbo... whatever you do, make sure you stick with divided housing and proper twin scroll manifold.
    • People have got to stop doing that. ShatGPT is not a search engine. It is a hallucination factory.   I also would recommend the 1.05. The .83 will "work" for you , in that it will be more responsive, but I think you'll find that it won't be anywhere near as good running it out to 8000rpm as the big housing will be.
    • Decided for the first time ever I would tow my car TO the track day on the same working theory as bringing tools and spares "if I have it I wont need it, but if I leave it behind i will 100% need it" all setup and ready to go out and try these A050 for the first time First session showed I needed to stiffen up the dampers a touch but still managed a few 1:21's without much effort. things were looking good. Came in a dropped the tyres down  to 26/28 as they had gotten to 35/33C from 22C cold The first lap of session two I managed to drop into 1:20's. Then in the second lap into the second session. Coming into T3 and I suddenly lost brake pedal followed by some huge rear end vibrations and scraping sounds. Got it back into the pits after session ended and found this. in the attached video, all of the wobble is in the hub its self, wheel is mint, and bearing feels tight. lKXLqpd - Imgur.mp4   Deciding it was a bent spindle I tried to find bearing/hub assembly locally but was unsuccessful so it was loaded back onto the trailer i luckily brought it on to drag it back home  
    • 1.05 you’ve gotta let it breath 
    • You have to continuously fill it to avoid dry running. Personally the transmissions I've serviced have never been bad enough to justify doing this because it is definitely a pretty complicated and somewhat risky procedure compared to simply draining the pan, measuring what came out, then refilling with the exact same amount.
