oh and manages13 my block and head machining has taken over 23 weeks alone (NO assembly at all) thanks to those involved 

shit brad the company i have been using will offen do the same day drop off and pickup if i prebook a week or so out B)

DUDE that is one nice list i only cringe at what it must of cost to put together as i know how much it cost for me to get my build together. Can i ask who you are using for the build and tune? and when you might have it on the road?

Thats definitely a dream setup.

Very nice pics.

With regards to the rb30det thing.. I think the biggest concern is the height. One big advantage of the 2.7 kits from japland.

But revability... Its got everything to do with gearing and how well the hotside flows. The VL's run a 3.45:1, run that in your Stagea and it too will feel like a big diesel. :(

tuning will be at Racetorque im 99% sure on. they mainly do race cars, and keep quiet in the performance scene in perth. been highly reccomended by another gtr owner with autronics and over 550rwhp.

the build is all done at home, machining hassles where through a few well respected perth shops but failed to show reliability and the shops told me 3 weeks for the block MAX and 2 weeks for head MAX. well im still waiting on the head which has been 12 weeks and the block was 11 weeks :angry:

PM me if u want the name of the shops i used for machining, as i dont want to upset the moderators :)

cost, hmm well im not gonna announce that here, bit over original budget though :lol:

should be in the car by xmas and run-in/tuned by end of january pretty definately. depending on the tuner :)

cheers

Brad

Is anyone else touching themselves looking at those pics?

Adrian

Yes i did...

Wow whats a setup i am jealous...

I think you have done the right thing with the 2.7 kit...

3 litre kits belong in R31's......

Hands down to you Brad, very nice job on your build - all top quality parts there. I'm sure you'll get power with reliability with all that gear.

Good luck with the build and keep us dated on the progress.

thanx guys, well im picking the head up tommorow finally, BUT it isnt assembled as i need shims for the valve springs, cause apparantly the JUN cams are regrind and have a smaller base circle.

so they aint even billet like HKS ones and are regrind from GTR cams. (thats the words of the shop doin the work).

so ive decided we will assemble the head as well, with the help of my uncle who usually does drag engines. shims will be arriving monday next week supposedly.

pretty pissed about the cams but, thought JUN was better than that? B)

does smaller base circle mean they are not as good in making power as a set of hks normal base circle size ones with same degrees and lift?

cheers

Brad

They weren't able to machine up shims?!?!?

The reason for the smaller base circle is to allow for a higher lift without or with very little head modification.

Tomei also uses this method to squeeze out a little more lift.

no they said the largest shims they had were not big enough and they needed "special" ones made or some shit. sounds like an excuse to charge a shit load of $$$ for f**k all :) gotta be custom made and specially heat treated or something they said.

i took the head off the shop cause they have had it 13-14 weeks to do porting and reassemble, so they ported it and wait till now to check the cams and whether shims r needed and now they delay it another week, plus assembly time. so i told em to not bother and i will do it.

Dont mean to burst your bubble but make sure you get it tuned by a reputable tuner. We tuned a 500hp built 930 Porche TT over here on the Gold Coast. It had been tuned by some guru in Perth that used all of about 5 of 200 available features of an autronic. The car was that rich that it had washed the bores!!!!

I was going to say give Greg at proengines a call about shims, he reshimmed my head and it was a pain in the ass but he got it spot on, with no bullshit. He has posted above me though, so thats obviously where he got the shims from ;)

Hi Brad, all of the Jun cams I have seen are billets. They have to use a smaller base circle to get the lift, RB cylinder heads don't have enough room. The Jun instructions and web site both quote the following for all lifts over 10.5 mm;

Clearance of head for cam lobe rotation required.

Special valve spring required.

Special valve retainer required.

The "Special valve retainer required" means the cam has a different (ie; smaller) base circle to standard.

:) cheers :D

There seems to be a few people that are having trouble with machine work being done on their engines, either they are very slow or not done correctly.

Greg at Proengines posts here on the SAU and the work he has done for me has been nothing but exceptional and in a timely fashion. Won't go anywhere else now.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
