Hey guys

The engine in my r33 gtst is getting a full makeover. The final result should show well over 300rwkw. I have been reading on the Internet on how to get flames out the exhaust after giving it a boot?

If you degut the carry or whatever it's called will you still get in trouble or will they see it has a cat and not know its gutted?

Also when it says the car is running rich. Does that mean you run it richer then normal or will it still blow flames on a normal tune just without the cat.

Cheers

Tyler

Yes gutting the cat will assist with flames, but it's a terrible reason for getting rid of that cat which is a critical part of the exhaust system. If it is a street car i highly advise leaving the cat alone or replacing it with a high flow metal one. It takes all the nasty chemicals out of the exhaust and traps. Without the cat you will not pass an emissions test if you have to pass one for rego whatever state you are in. If you gut the cat its still pretty easy for a switched on policeman to tell, just stnad behind the car when you rev it and it stinks, whereas nowehre near as much smell with the cat.

Getting caught withwout/with a gutted cat is a maximum penalty of $16,000 if i remember correctly.

Have fun.

Grab a fuel injector. Weld it into the exhaust system with an ignitor. Wire it all up with an activation button under the clutch pedal. SICK WAN!

But seriously..

Skylines get enough unwanted attention without shooting flames. You might change your mind once you get done.

Grab yourself a nice venom cat! :thumbsup:

Hotrod used to use a spark plug in the exhaust, and let it run overly rich on deceleration.

That's how they achieved it.

I personally wouldn't worry about it.

How are you going to see them?

If to impress others, a car thats quicker with less flames will generally impress more.

Either way, good luck.

Hope you don't blow up.

Yeah screw it.

I don't want to lose the whole car or have to spend more because of defects just for some flames. Ill see how it is when its finished and spend the money on something else.

Good call !

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
