Is this build really built for response, 8.5comp and no VCT sounds more like a big boost top end setup??

How would this build compare to a RB3025 neo with VCT and 9.5comp with even 50% E85 mix... surely that would of got big torque low down...

Yes I was trying to get response and from what I had, it is pretty good. It is very linear as it goes from idle to 6500rpm, well that was the highest I could go on the revs before it played up. But when I first came home I did get the chance to give it a launch from 5000rpm and there was a little 4W spin and no lag, so I guess you can say it has pretty good response.

To get near that before I was going from 7500+ rpm and it would still dig in a bit

Have no idea about your comparisons , I am sure there will be some blokes that could answer your question :)

Has to run on 98 and you have to stop spending somewhere

Everyone would love V-cam....but cant always afford it

Lol, how exactly does VCT help response over dialed static cams when response is all you are after

Yet still yet to see any proof VCT is better then properly dialled cams

The advantage of VCT is that you can dial in your cams for response at as low a revs as possible and then still get a good push further up when your static cams would lag behind. So VCT does not of itself create better response but it enables you to set up for maximum reponse while getting better power further up than if you did not have VCT.

QED

LOL

ROFL

So what your saying is VCT does not help response against cams dialled in for response :thumbsup:

Proven !!, really, where exactly is the proof, i read alot of people saying it's better but still no ACTUAL proof

Way to be selective in what you read.....

The whole point of VCT is that you can have the (int eh case of a RB25) intake cam set for max twist down low, then have it change over to carry the torque curve further up the rev range....

But Porsche, Ford, Merc, BMW etc etc must all be wrong......

Lol, kettle black mate

The point started at someone saying built for response but don't have VCT, i posted how does VCT better static cams dialed for response then Kiwi responded basicly confirming what is said

At no point did any one mention response AND topend :/

As the guys mentioned, i have posted my graph of my stock factory RB26 more then once for people to beat for both bottom end as well as top

And i'm still waiting

We are also only talking RB25 VCT V RB26, or any other cam timing setup that only changes the inlet cam timing from one maximum to the other, though would love to see how a RB with the VE cam setup would go

ooooo.....where?

Xkalaba, don't take it as a personal attack you have to defend!

I don't like your chances of getting a guy with stock turbos chucking vct on, so I don't think you will ever get the direct comparison you are after.

What's your idle like with the dialed cams?

Spends 8k+ on VCT kit but keeps stock turbos :rolleyes:

Idles like a babies bottom, smooooth as

Not like the 34, lol

Like i said, i'm happy to see a NEO with any turbo you like, so given the NEO has a "better designed combustion chamber" and NEO and the latest tech single turbo you can get it should easy walk over my 80s tech bush bearing factory twins on a static cam setup

I want to see same boost (19psi) run 290+rwkw and beat my 26 for response then prove it on the drag strip cause we all know dynos can be made to lie

I'm starting get personal about it cause every time i come on a performace thread someone throws up should have gone NEO or VCT and saying it with no proof is misinformation

ooooo.....where?

Fark it, cause one more time won't and you asked so nicely :P

This graph was done at a SAU dyno day back in 2007 4 days after the full wieght plus stereo R32 GTR ran back to back 11.3@125mph with a stock motor, the stock turbo world record in the link in my sig

I should have bought your car from the get go, would have saved me a shit load of money and hassle , haha

I need to learn more, but arnt the RB26 and the neo25 pretty similar heads ( apart from VCT) , if they arnt that much different then the VCT would of been good, in comparing response im thinking about how 34GeeTee's 2.5L graph with the HTA3076 has 280kw's at 4000rpm and that doesn't even have a stroker kit...

    • 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"
