Okay guys just recently bought a series 1 r33 and recently installed an aftermarket boost gauge which reads about 10psi.

I sussed out through the threads and judging buy what my stock gauge reads it converts correctly.

What bugs me is that im pretty sure the engine is near factory all I have done to it was install a podfilter and just a regular canon (came with car)

Shouldn't it be reading around 7-8psi? I thought that was std factory?

let me know your thoughts.

Pod filter gets the engine breathing better, will free up a bit more flow. Cannon wouldn't have made much difference but probably wouldn't need to. The gauge is possibly a little bit off as well so it's not too much of a stretch for the pod to have freed it up to about 10.

Otherwise are you sure the previous owner didn't install an RB20 actuator on the turbo, they are a 10psi spring.

Oh right, so he did.

Still, stand by that statement though :D

Have run back to back with stock aitbox/pod. zero difference.

But back to the other thing i noticed.. raising the boost with an EBC and having a stock exhaust? Interesting way to do it dont you think?

Well it obviously depends on the pod/panel filter/etc in use, but I've definitely seen just a pod filter free up 1-2psi before.

I suppose if you're comparing an 20 year old stock filter maybe. I did an Apexi pod vs an Apexi panel.

Lets not forget that parts like split fire claim huge gains too.

Oh yeh for sure, I'd have rated the apexi panel over the pod, interesting that there was no difference. I imagine that if you had done a few full load runs then left the car to sit and heat soak, there would have been a bigger difference.

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • 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.
