What turbo/ 's are you going to use ? Interested to know as I have similar 2.8 build being done here in Japan by HKS.

They were reccomending HKS 2830's with the V Cam and 2248/274 cam combo. Supposed to idle pretty standard but boost comes on real early and pulls all the way to top RPM..I went for drive in one of their customers gtr and was bloody impressive.

V- Cam unpacking

I have always found the unpacking process fascinating, so I have documented it with these photos to share with everyone.

Thank goodness Benno has worked out how to install it. The instructions are entirely written in Japanese!

dont mean to sound like a retard but is the HKS vcam kit essentially the same thing as the RB25 VCT? variable cam timing?

sure the RB25 setup you can't touch / tune etc, but the same logics, that is, a variable cam timing system - cam timing that changes, with load etc

A set of off the shelf Garrett 2860R -5s will be installed.

In Cam as per V Cam Type A setup - Valve timing 90-120 degress, valve lift 8.6mm, duration IN 248

Ex Cam - 256 valve lift 8.7mm

It should be interesting how much boost these will develop in the hands of the maestro. The secret is in the rest of the package so I am led to believe. The truth will be told when I take my first test drive once its completed. Car is in the workshop atm.

You are spot on paul r33. If I put a RB25 head on a RB26 bottom end and get someone who knows how to put it together, then I will essentially get the same result without the HKS badge!

Sneak peek:

= Total Awesomeness!

I saw this beast finished @ Beno's today, when dropping mine 32 in & picking up Pete's 32.

This 34 looked very clean & crisp. Good Luck with car bud, seems u pland well & workd hard to achieve a fantastic result.

Keep us update..

:mad:

so its just the intake cam that has the VCT yeah? I would imagine this would be much more efficient than the 25 VCT as you can tune it right through the rev range not just switch it on and off

Sweet setup, so its nearly finished? make sure to post a dyno chart when its done:) will be a response monster!

I believe my car is next in line... I should have bribed Benno to drop that stroker crank into my build, you would never have known;) lol

No dry sump? :P

Dry sumps must be a NSW thing. As far as I've seen at the track, there is not one dry sumped car in Vic, however we never seem to see oil starvation blow ups either.

It sure looks sexy with the pumps and all, but is it really necessary for club cars where a well made sump does the trick?

There sure are some monster RB's in the build right now.

Glad i know of a couple that are NSW based so you Vic guys dont hog all the fun hahaha

Seriously though, great setup, looking forward to seeing the results :P

No dry sump is planned. Just a larger capacity oil sump with High performance/high flow Tomei Oil Pump. In fact the V Cam needs oil line to work properly and HKS does recommend a higher capacity Oil pump.

That does look like a fairly simple system, I guess yes the principle is exactly the same as the 25 VCT, oil supply, a solonoid to switch it on and off...this is awesome!

The thing I like most is the HKS POWER rocker cover. Its very very special, and they even give you the little red V-CAM badge!

This car will be insane...considering Aaron's 34 with the 2.8 and -5s made 350kw at 3,500 rpm? and 450 at like 7 something? (Cant remember exactly).

Built by the same genius plus the V-Cam....I really cant wait to see the graph...

Really good work on the pics Matt, its like were all opening the box ourselves! Except we dont get to touch and do other naughty things with the parts :)

I must admit Ben is like an eccentric craftsman (no offfence to him). He has good enough reputation for him to be selective with his clientele. And no he did not shake his head when I approached him with the job. Its for other reasons which will come into light in the near future.

As for turbos, I can't get hold of any Garrett-5 as they are on back order world wide. I am considering a set of HKS 2530s or Tomei ARMS B7660 now. But just for the HKS or Tomei brand will cost twice as much as the Garretts off the shelf. :P

Seeing Benno tomorrow

Dont mean to do a thread hijack

I'm in the same boat..once I made the decision to go the -5's and ordered them up, been waiting a good month or so and looks like awhile yet. Glad my head is taking forever and everything is at standstill.

If you want to spend some coin, most guys here running the V Cam go the HKS HKS 2835's with the and 248 In /274 Ex... they are beasts to drive, absolute weapons but pretty exxy.. I could get you bit of a discount thru HKS if your keen. I initially had this plan but went the -5's as was just after something near the 600-650ps margin. The HKS 2835's and V Cam would be easy 700+ps. The ones I have test driven have been 700 to 800ps..

What computer unit you going to run. Reason being there is another bloke in WA dunning Apex Pc and having major dramas. I had a talk with tuning maestros guys at HKS and they reckon anything other than Fcon Vpro and mdel before you will be pushing shit up hill..its doable but you will have a hard time trying to sort it out. Its typical HKS, all their stuff is made to run hand in hand and not with the competition.

I'm trying to suss some tuners in oz who would put up their garages for a week or 2 while my mate comes out and does some tuning but there is the whole political side with HKS to work out yet. Right now its an idea but we've put it on the table here and see what happens.

This was a GTR33 that had limeted edition V Cam

    • careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?
    • OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.
    • I’m thinking that’s the route I’ll  go, thanks for the input!
    • Hey all, my 2004 Nissan Skyline 350GT overheated the other day with coolant boiling and leaking out of the coolant reservoir when I was parking. So today, I started it up again just to see if it was a thermostat/head gasket issue. After about 20 mins of running, temps were normal again, no coolant was leaking out and the upper reservoir hose was warm but my engine suddenly cut off. I checked the oil dipstick and cap when it was running and there was no white foamy residue and the exhaust did not have white smoke. I tried starting up the car again but it would only crank, similar to when I had a camshaft sensor issue just that now there’s no check engine light on the dash. Any ideas? Unfortunately I don’t have an OBD2 that can read the Nissan's programme.
    • Bump on this to not make another post, had a ‘head drain’ leak on me and have the engine out as we speak. Planning on just putting a new freeze plug back in , plug the tapped holes and just be done with that headache.    Now I still want to relieve pressure to allow oil to pass down the blocks returns easier. I’ve seen catch cans with multiple vents help folks with this issue on this forum.  I’m wanting to make my own. I have some pictures here of my setup if anyone can help how I should plumb and design the catch can I would deeply appreciate it !   rb25 Oil upgrades: 1.0mm restrictor n1 pump/billet gears extended crank collar  extended sump with trap doors/w welded fitting
