Nice new block . How much oil does the sump hold?. Interesting manifold!!

[DRD-00F]

Haha... everyone is going Hypertune these days

Not worried about losing the ITBs? Spose with that much power you wouldn't really care...

Have a closer look DOOF...its a hypertune ITB manifold. Note the short runners, the mounting point for the linkages and the lack of a mounting flange on the inlet.

Its the same manifold we run on our Superlap car.

OOOOOH!

Last time I checked, their website doesn't say they do that! There also aren't any for RB25 on the website...

Don't spose you want to spoil me and say they DO have an RB25 plenum Paul??

me?...spoil you...not a chance

The sump is supposed to hold about 8.5 litres and has fitting for return line from head to sump. I have remote oil filter setup and line so oil change will be bloody exxy!!

The plenumn is as Dirt Garage said. its from Hypertune and for RB26. Guys from HKS wanted me to use this.. http://www.endless-r.co.jp/pe-ji/orijinaru/gtr_saji1.jpg but I decided against single throttle setup and wanted to fly the aussie flag a bit and show em what boys down under can do , so went the 90mm Hypertune and keep the 6 throttle setup and hopefully more response.

Question I do have for Dirt Garage or anyone else is... if it was your engine, what oil pump would use?? HKS boys want me to use theirs, told me to steer clear of the Jun pumps but I was thinking of going the Tomei pump...any reccomendations or opinions??

I use JUN or Tomei for my big builds and have never had an issue with either provided sump capacity is ample.

How long did it take to get your hi octane sump?

[elrodeo666]

From order to delivery here in Japan was just over 2 weeks.

[elrodeo666]

Well was back at HKS today and block has gone off to the machine shop to get the full treatment and wont be back to early feb.

Still waiting on some parts to rock up from HKS headquaters but things starting to roll along which is good. Their workshop is pretty massive,got the full tour today, there's big undergound garage plus upstairs garage plus they have temperature controlled room where they do all there machineing work,theres the dyno room , plus 3 service pits plus 2 level parts customer service shop..

Anyway not much to report on but hopefully over next 3 weeks block and other parts will be back from the machine shop and engine starts getting put together. They are doing a step by step photo disc so will have other pics later.

heres a few from today..they aint the best as it was -7c today and definitely wasnt wearing the right clothes to be standing around the garage freezing my gonads off..

This was one of the customers cars...700Hp beast..Its got its winter wheels/tyres on, summer it runs big side skirts. The V Cam setup is HKS Limited Edition..only 30 made and this is no 20.

this was one of their race cars

Rods and Crankshaft...

Been awhile since I posted anything but the block finally came back from the machine shop around feb 20th and since the boys have been busy putting all the go fast 2.8 kit together, all balanced and prepped and wacked together. They reckon the block was one of the cleanest ones they have got straight from nissan as far as the casting went. They seemed pretty impressed.

Anyway heres a few pics from yesterday and first unveiling. I have new head coming from Nissan which will get sent to NAPREC for maching then back to HKS for the port polish etc, so looking at another month before the head will go on then so bit more thumb twiddling and chasing parts before handing over the car.

Still havent come up with final decision on turbo setup but have ruled out the 2830's and V Cam as thats another ￥800,000 plus ($12,000 plus aussie) and that coin will be better spent on new OS giken box and some suspension mods (Nismo Link set)

Any input on turbos be much appreciated. I'm looking at HKS 2530's , HKS GT RSS, and possibly modified Garrett 2860-10's.

Anyway hopefully over the next few weeks I'll get a few more pics up as more bits and turn up and get bolted on.

The first look..

Nice and new..

Wrapping it back up and waiting for the head.

More parts

Still not alot to update on...

Spent the day out at HKS on saturday trying to finalise what head work will be done, what cams etc..Got to thank Paul (Dirt Garage) and Russ and Gav for their input and advice..cheers fellas..

Pretty much looking at this setup as far as head wise..doing a como of high response stage 2 kit and drag kit..bigger valves etc...

Whats on the list is as follows

Naprec High Response kit plus combustion chamber mods and machining.

• Drag Kit for RB26 : JP¥315,000 Replacing NAPREC Forged Big Valve / Combinations Valve Guide / Heatproof Sintering Sheet Ring / Cam Cap Stud Bolt / Exchanging Valve Guide / Replacing Sheet Ring / Sheet Cutting for Race (Matching the thrusting point) / Hall Processing to Pull Out Air of Water Jacket / Processing Oversizeｄ Jacket Plug / Head-face cut to 1.0mm
  

Also water jacket will be modified plus using Jun Titanium valve retainer plus HKS modified Valve lifter. . HKS step 2 valve springs. HKS will do the port and polish.

Cams I'm looking at either HKS/step2-10mm lift 264 degree in & ex or tomei poncams 260 degree in & ex with 10mm lift. Still havent decided which to use as yet but have to make decision by end of the week so machinig can be done..

Turbo's..mmm still undecided but still have some time to decide as head will be awau for a another month...

I did get to go for a drive in their race prepped WRX...bloody fun car to drive as power to weight ratio is pretty damn quick and its running around just under 400 HP but its the suspension setup thats killer, real smooth on the bumps but handles amazingly but hey the can throw the best of what they sell in.. Shocks are a modified Hypermax Sports setup and are amazingly smooth.

On the way out I pulled up next to this Sierra Cosworth..rare as hens teeth over here..
