Awesome setup, some top quality stuff on this build.

Whats done oil control wise though? Still standard bottomn end?

Not really much, Had a standard rebuild in Japan by Midori Seibi using an R34 block and crank etc.

It is great seeing other people's setup and appreciating the hard work and $$$ that have gone into the build.

The gauges look great. Do you have a wider angle pic showing how they fit into the interior?

Cheers mate, Will get a better pic when i pick up the car next week. They went into a HKS glovebox insert.

Haven't been here in a while, long story short need a new motor..

Going with an RB25 AWD 23U block and will run a special Platinum brace and still keeping the T51R KAI BB kit, goal is 750 - 800hp

The whole bottom end rotating assembly will be sent to WPC Japan for metal treatment after balancing is completed.

New parts consist of...

Spool 2.8 Stroker 86.5mm CP Pistons and Full Counterweight Billet Crank
Spool Spline driven oil pump gear
All new Supertech head components, will be going shimless head..
Oversized Inconel and Nitrided valves, dual valve springs, DLC coated buckets, bronze guides etc
Ross Balancer and Cam/Crank trigger kits
Tomei 1.2mm Headgasket
Quaife ATB Front diff
Koyo 3-layer copper core radiator
Nismo engine mounts

More to come...

[GRKGTR]

So finally been getting somewhere recently.. Received all my parts back from Japan, just waiting on piston pins to come back from getting DLC'd.. 

Went with ATI 1000hp Balancer instead of the Ross due to some disturbing issues I have seen.

All bottom end parts have been WPC treated.








And now the block is getting line bored with this beast...

[GRKGTR]

Tunnel boring is finally done, and now onto a much faster/reliable machine shop to do the honing, balancing and assembly.

Also upgraded to half inch mains and head studs.

[GRKGTR]

So finally the last pieces of the puzzle have arrived..

DLC Pins and Buckets!

Block and all rotating assembly went to the machinist on monday to get all balanced and torque plate honed for the 86.5mm pistons, so that should be all done by mid next week, then we will be ready for assembly!

Few weeks to go and we might be ready for startup

[GRKGTR]

Block back from bore + honing and now onto the engine stand, hopefully should be done in a couple of weeks.

[GRKGTR]

So after a couple of delays...

We are at the final stage!

 

 

Almost ready.. couple more days of work and it should be in the car ready for startup.

[GRKGTR]

Can count the days left on one hand..

Waiting for couple of small pieces to arrive on monday and also an oil accumulator for some extra peace of mind.

[GRKGTR]

Fast forward a few days and here we are!

No exhaust on at the moment just the dump pipe.

Tune next week ?
 

 

[GRKGTR]

So some tuning happened today and successful testing of the billet alloy brace from PRP, we had solid/consistent oil pressure the whole time.
Proper test will be on the track then pull down after a 6 months to see how the bearings look etc

 

Here's a short pull, found that one of the pumps could be on its' way out and will be looked at tomorrow then replaced etc.
 

 

 

[GRKGTR]

So tuning is complete for our goal..

On pump 98 made 427kw @ 26psi..
E85 made 538kw @ 30psi but backed it off to 520kw @ 28psi

Now just want to drive it around and enjoy it and experience it on circuit!

4 inch titanium

Gun. This is mad.

[Marko R1]

Great thread and very nice result!!!

[GRKGTR]

So haven't updated this in over a year and that's because the car has been running great the whole time  Over 6,000kms and 4 track days to date with the alloy brace still working wonders.

But in any case the GTR rabbit hole doesn't end and just gets deeper.

Next (hopefully final) phase of this project is looking like this..

1. Alpha Omega Single piece driveshaft (Acquired)
2. Brand new head (Had this in storage for ages) CNC ported with all new gear, shimless etc
3. HKS V-CAM Step Pro (Acquired)
4. Upgrade to Haltech Elite 2500 for DBW compatibility
5. 6 Throttle ITB DBW
6. New turbo, maybe Precision 6875 or 7175/7275??? (Don't know which one to pick yet) 
7. Bigger catch can/battery in boot etc
8. Sequential Gearbox (One day, not sure which one)

Here is some really short clips of my last session at EC in RWD just mucking around..

Looks like a weapon - 3rd gear breaks out

It's in rwd in the video and it's tuned so the boost rolls on progressively as opposed to the cliff face type tunes lol
Only on low boost (650hp) in the vid but still fun and plenty of power
