Efi Question...

[JJT036]

Hey guys,

 

Would I need to run a Catalyc Converter if I went for an EFI Setup on a 4K?

 

Josh :cool:

You don't need to from a functional point of view. Will work exactly the same with or without it.

 

Emission legality is another issue but I doubt that is your concern.

Cheers Parrot. :y:

 

We're gonna do EFI setup on the Ke36 and register it WITH the EFI. The most it'll do is put me in front to VicRoads because we'd be helping the emissions. We'll find a Commodore Cat for the RWC and Reg and leave it in there, so then the Motor won't Seize on us. :)

I'm fairly sure the law states that you must adhere to the emission laws of the of the year the motor that you convert to is made. Don't quote me on it, but I'm 99% sure you only need to adhere to 4K emissions, but if you like the planet it doesn't hurt running a cat.

Hey Josh, if your sticking with the 4k I wouldn't bother with a cat converter as your not converting to an "unleaded" or post 1986 engine. So you'll only need to comply with the earlier emmision laws. If you still decied to put one in to be a bit greener be carefull of the commo cat converters they tend to fall apart internally and block up the exhaust if she runs a bit rich. Could try a performance stainless cat but price compared to a commo second hand on will be a fair bit more.

They aren't that hard to fit I'd just wait till vicroads ask for one.

EFI Ke-36 pano would deff = WIN

stu.

I'm one of the lucky ones with Pre-Emission 4K Ke36's, so I won't need all the emissions crap for it. Although, the 4K I'm about to drop in, is from a Fully-Emissioned KE70, but I should be safe.

 

I'll be definitely going for the EFI, as it give's more power, for less Juice - although I'm not much of a Greenie myself. :P

 

I'll need to find a Cat to suit a 2" system so we can just cut out a section of the Exhaust System, and weld the Cat into it.

Hey, you're fitting a cat when you legally don't need to - that make you a greeny dude :P

 

I'm gonna get a 100cpi ebay special cat for my rig, were legal up to a year or 2 ago, but now they can't be bought from exhaust shops and fitted from what I've heard. All legal if you car "already had one though" ;)

Yeah I know. A Cat would give me more Power and a longer lifetime for the 4K, 'cause without one, the EFI will cack itself and take the motor with it. :fuzz:

Whether you have a cat or not shouldn't contribute at all to engine-life etc (only thing it might do is through a CEL if your EFI system is expecting a cat-O2 sensor), no will it give you more power (if anything you'll get a tiny bit more power without the cat due to the lack of restriction). Your emissions will be up shit-creek on unleaded without one, but there is NO impact whatsoever on the engine if there isn't a cat (a BLOCKED cat on the other hand can destroy an engine, but for different reasons).

 

Remember that catalytic converters were only introduced for unleaded fuel - you had EFI cars before that running on leaded fuel without catalytic converters.

Wrong, wrong and more wrong.

 

You don't need one.... lagally or mechanically, so don't bother. :no2:
