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 !

    • It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣
    • Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
    • Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.
    • Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler? 
    • Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed
