I bought the 5in Venom cat and had it welded in (no flanges) as I am not planning to remove it. I have a 3in system looking for about 300 -330kw from my RB30. We need a cat for low volume certification these days but the certifiers do not do comprehensive exhaust gas analysis - I suspect these 100 cell metal cats would not pass - would be interested if anyone has been through a test with one.

whats the point in spending all that money and running a high flow cat if it doesnt meet emissions? seriously, just bolt in a standard cat when you have an inspection then spend $50 and get a decat.

recon a minimum of 300 cells for emmissions and get it as close to the turbo as possible, can change it to a 100 cell if you want when you get your certificate for the engine

The point is to avoid a $10k fine if you get caught without a cat at all. Compared to a $200 outlay of a 100cell hiflow cat that will provide almost no restriction. You cannot get a fine for having a cat that probably wont meet emissions standards (100 cell cat).

i dont have a stock system and its on a vl so the whole exhaust is custom made

It all depends on the impact of you failing. If it costs nothing and you can go again later sure try the hiflow cat but if it costs you or you failing causes you to loose rego then you should definitely fit a 300 cell cat and then change afterwards.

Show me proof that anyone here or elsewhere in AU has been fined the full amount of 10K for not running a cat converter.

Pete was stating that its better to run a std cat than a high flow - which probably wont pass.

Why run the risk of a fine for no cat?? To save $200 and 2-3kw?

Yes I also have said multiple times in this thread to run a standard cat to pass the emissions test. I was suggesting changing to a hiflow 100 cell cat after the emissions test.

exactly, its just a waste of money. the only way youre gonna get fined for not having a cat is if youre stupid enough to go through an inspection without one

You may not be aware but in Sydney they often have defect stations. Little outposts setup by police where police will pull import cars and other cars on the street into these stations, put them on a hoist and defect everything not standard.

im not sure what your point is? Again, pete's reply was that a highflow is a waste of money, as it would fail the epa test and if you went through an inspection without a cat, then expect a fine.

Here in SA, you only need the one defect to be sent for a full inspection (can be a few things like noise etc) and then fined just for being defected

I don't think you understood what I meant. These are EPA setup stations. Police bring in drivers, EPA pulls out the book for your car and gets you down for everything not standard. You will cop a fine for running a cat not meeting standards, not a fine for running NO CAT at all. That is the difference. Its a grey area. They have hoists to get cars up. Ive seen one setup on james ruse drive near rose hill. Not a pretty site.

I don't think we have them in WA, the only Police setup stations I've seen are your typical RBT buses & drug test.

Also from watching some old news, you guys also have some kind of special Police task force who's solo purpose is to pull cars (mostly imports) over & defect them, I think they are called operation Tapan or something?

Again we don't seem to have those in WA (thank god!)

dont count on it being that way for much longer. . .usually what happens in the east makes it way here to W.A (aka Wait Awhile) eventually

it's all good arguing about this on a internet forum but know one here can give you a straight answer (or at least the one you're looking for) so email venom an see what they say. :thumbsup:

good luck to you sir :)

george told me my best bet would be a factory BF xr6turbo cat for the emissions test. then change it over down the track.however after talkignt o him a bit more any 200cell plus cat should do the job as long as its ceramic. so im thinking going the catco ceramic cat and then putting my decat back in after the test.

im not sure what your point is? Again, pete's reply was that a highflow is a waste of money, as it would fail the epa test and if you went through an inspection without a cat, then expect a fine.

I understand you now, drive around with a decat pipe, if you get pulled over and cop a defect then put a factory cat back in when you go in for an inspection.

What about this scenario:

Car accident where the car is undriveable and the insurance people come and do an inspection of the car. They could argue that your car is not roadworthy and therefore not covered by insurance.

    • Keen to see the turbosmart data, to date I've only seen negative things in terms of response for them. Very small sample size though.     Hawkins is a big advocate in his videos of the larger rear housings. I managed to make similar power with a lower spec motor on the smaller .8 rear, keeping decentish spool.  The people he works with now are big power cars compared to mine though, mine really is setup to drive around and enjoy.  I don't have any back pressure monitoring though, so couldn't say if its good or bad on my car, just that it does what I want it to do.   Future I want a higher compression more cubes motor to give a bit more bottom end and hopefully the new g35-1150 gets me to the 850 rear comfortably.  But maybe I won't due to exhaust back pressure.
    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
