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

  • 3 weeks later...

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

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
