Will potential power be power reduced? Yes. More Importantly your turbo will not be able to produce boost as "efficiently". This will result in increased lag and higher turbo temps. You can pick up second hand decent CATS for <$200. It's worthwhile investment which you will never have to touch again.

hmm interesting, you guys would be right hmmm awell cat it is then :) still the go ahead will be known date from friday arvo once i get comp/leakdown test done

So far so good, i mean its not consuming oil or turning it black before 5000 kms of moderate driving, not blowing smoke of any sort, so i can see from the small picture it should be fine, the large picture well will be known on friday guys ;)

I guess suggestions would be very much appreciated on the catco cats from bosimporting, which one would be ample for my needs also results if any would be great aswell cheers guys

Ok so my compression values are in and leak down values what do you guys think:

Cyl1: 155 8%

Cyl2: 155 9%

Cyl3: 150 10%

Cyl4: 155 12%

Cyl5: 150 12%

Cyl6: 155 9%

Since last dyno made 178.9 rwkws before front pipe install so still running standard front pipe and dump

Also did power run whilst doing comp values to see if still in tune, seems that it is and with the new front pipe being the 3" complete front and dump comes to a new value of 197.3 rwkws.

The difference in IT's was 39 before and new of 41 with this one

So i think it would be safe to say that my project should be done mid november now :laugh: woohoo

Cheers

No mention of boost controller?

Assume you've already got one, but if not, you need to ensure you have something that will reliably hold boost if you're looking to push that amount of power, particularly on std internals...

Boost spikes = very bad news on std internals.

A few to consider...

Greddy Profec B Spec II (I have one of these - works well)

Apexi AVCR

Turbosmart Eboost II

Was running the hybrid boost controler. but have found its in effecient at holding bosot, although the hks turbo has an addjustable actuator on it i may just use that at the moment instead for boost control and later move to a better brand controller, will let you know how i go and keep you guys updated

The two of the latter ones best bet i say, pending your power goal, and big difference in prices. will post dyno results next week when all done, On another note, regarding the highflow cat, did anyone notice a Sound drop, either im going deaf(I dont think so) but have noticed that since i put the cat on, my exhaust note/loudness has droped dramatically, quiet to compare against what it was?? Go figure

Cheers devils

Me either, I'm torn between a 2835proS, the 3037proS, and the GT3076R, so atm all dyno results will help me decide.

Maybe your old stock cat hollowed itself out and was basically functioning like a punched out cat. So when you chucked the hi flow cat on, you put a bit more restriction back into the exhaust system and thus the drop in noise. It shouldnt be that noticeable tho imo even if ur cat was 100% hollow

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

      What brakes on R34 GTT(Europe)

      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

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      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

      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.
