As Dose said before, if u want to spend cash do it on more value for money stuff.

But if u have the cash this is cool, but it’s designed to sit on top of the RB25 lower shell

90mm throttle body

big throttle bodies don't magically make more power.

You only need to go bigger if you have more boost pre throttle than post throttle when at WOT.

68 or 74mm DBW is more than sufficient for most people.

Would a 74mm be fine for a Neo 25, 98 fueled 300wkw or 68 would be more appropriate?

Well, tell me how I can make around the 500-600hp mark with a T3 top Mount turbo if my Aeroflow 6262 .84 T4 is too big as I was going to build it for 5-600 and flex fuel and stages like boost Lvl 1 - 15 psi boost lvl 2- 20 psi boost lvl 3 27-30 psi for example 

I'm running a greddy style plenum with stock throttle body on my rb30 (rb25 series 2 head) stagea, it is making 400kw through that.

There are plenty of ways to spend money on the car, you don't need to change the intake you have for 600hp

74mm would be good, however you will find you will need to gently ramp in the pedal vs. throttle so it feels smooth and linear (not like those silly carb V8s where you touch the throttle 1mm and the car wants to fry tyres).

This is how mine is dialled in with a 74mm DBW TB, I wanted 68mm but Plazmaman couldn't weld a 68mm flange onto the plenum.

You said you want 373kW to 447kW, you don't need a 62mm turbo to do that, that turbo can spin over 500kW+

Okay I must of got my letters wrong instead of hp  I’d like to make 450-600kw i know it’s quite easy to make it on an RB I already got the turbo for free so it’s brand new the aeroflow 62 .84 T51r mod already done T4 flange can I change it to a t3

 

but please tell me how 

Is there a reason why you want close to 600kW in a R32 GTS-t?

Have you thought about suspension work, subframe changes (from a newer car, offsetting it), diff choice, brakes, gearbox?

There's a high chance you're running a RB20DET gearbox which will not like close to 600kW being sent through it.

Also a 6262 won't get you close to 600kW.

@Dose Pipe Sutututu  thank you so much, understand what u mean and appreciate that info

I think way too many people get caught up in the whole bigger TB for more power, but that's only if it becomes a restriction.

In a FI environment, the TB size is not as sensitive, where as in a NA environment, you find with the throttle at 100% and if the plenum still registers a vacuum, then your TB is undersized and requires to be upgraded.

    • 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"
