Hey everyone, am nearing completion of my RB25/30 build, but I seem to be stuck on setting up the timing.

 

I have drilled and tapped the block above the water pump for the timing belt tensioner, am using a RB25 idler below the water pump, crank is at TDC, but am unsure on where my cams are supposed to be at. I also have adjustable cam gears to go onto the cams, once the motor in full is set to TDC correctly. To make it easier, the block is a standard A6 VL N/A block, and the head is standard aswell, valves, cams, with the exception of the VVL being blocked off in the head.

 

If someone could help me out with this it'd be muchly appreciated. Have tried searching in this thread alone and also the whole of SAU, but cant find a definite answer. With 359 pages worth of thread here, I tried looking, but it seems a lot of people like to talk shit in here too which makes it all that much harder..

Install the adjustable cam gears straight off and use the markers as per Ben's comment.  Then pay someone competent to degree your cams.  Hint: this is far easier and less time consuming to do on the bench/engine stand.

Hey team. 

Massive thanks for this thread. It's amazeballs. 

Just wondering if a factory 25DE ecu could be used to get a 30DET running. Just temporarily so I can check everything for leaks and I'm eating myself noises before it goes for dyno tune.

Not sure what ecu I'm going to use yet will speak to the tuner before to see what brands they are familiar with. 

 

Once again cheers guys

I know....Rb25/30 boredom (not build ) question...but opinions will be cool

Need to know some real Hp/Kw figures for my build...just your guesstimation possibly. 

Build

25neo head.+1mm over int/exh..rear head drain

Stainless valves ..performance springs

Tomei cams (poncam)

Ati balancer ...prp collar..n1oil pump..forged gears..prp billet crank sprocket washers...billet backing plate to n1 pump..7L sump.. Stock crank acl bearings...87mm rb30 block..CP flat top pistons...Max peening H beam rods.

Fuel cell...1000hp fuel supply..1400cc injectors. 

6boost exh...45mm hypergate.

Haltech elite2000....flex fuel.

Real reason is so i know if my gearbox is going flying...

Is this still the thread to read with regards to high hp sohc rb30 applications?

Most stuff on here will relate to DOHC heads.  
What info specifically are you chasing?

Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

    • 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"
