6boost are monitoring this thread. I didn't buy them direct.

I was certainly monitoring the tune, had my wideband O2 hanging out the side pipe. I kept the boost down as I had no head room left. Plenty left in her with more fuel. I'm half expecting my damaged to be oil surge related to be honest.

Flow tested the factory manifolds against the chinese stainless and they flowed 50% less, 6hrs of porting the OEM and got them within 15% of the stainless.

Interesting info, any idea where the 6boost manifolds stack up?

Hmm bugger...

So what was the end result with the manifolds? in terms of power/response gains-losses.

I didn't get it on the dyno. However:

1bar was made at the same point, but may improve if it was retuned

my 1000cc injectors maxed out at .35bar less boost so the car makes more power no question

No losses anywhere.

Idle is less stable however....

Yeah shithouse ay.

Are you going to make any significant changes to the engine power wise or are you just upgrading the oiling side?

Still keen to see dyno results back to back...but theres no denying seat of the pants feeling, except for placebo effects :)

It will certainly be on the dyno when it's back together. I don't think I need any more power...can't imagine what it will go like on 1.8bar. May fit the bigger plenum I have here while its out.

Is it a MAF based ECU?

thats no good about the engine! from past experiance no3 or 4 spinning and the rest of the bearings ok tells me oil debis. as they are the first to get oil. and the first to get any contaminants aswell. where as if its no 1 or 6 then id look at oil starvation as a posible cause as they are the last to get oil.

unless a grub screw fell out or something..

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • 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.
