Hey Guys,

Did a search but couldn't come up with much.

A few people have recommneded stock original GTR metal cats to me. Does anyone know how they compare to say a ceramic high flow Catco jobbie?

Obvioulsy metal is the preference but not sure if the stock GTR cats would flow more than a "high flow". Be it ceramic or not.

Any help is appreciated.

Wow, looks like no one knows. I want to know the same thing! Did you find anything out?

Cheers,

Chris.

I'd go a straight pipe with a cat converter casing around it just for looks... Hehe!!

It does not hurt to go the high flow cat as I find the stock GTR cat a bit restrictive.

good idea hehe *unscrews stock cat casing*

Expect flames and puffs of black smoke with the decat pipe but there is definitely a noticible power gain to be had over the terribly small/restrictive stock cat.

LOL!

Sure is johnny.

BTW haven't seen you around SAU for a while...

The decat pipe is fairly illegal!

The Catco ceramic flows enough for good power on not obscene boost as shown by Just Jap's R32 GTR and others using it. I'd go with that - quite cheap too.

I have a stock R33 GTST cat converter with no guts. I bought an 3" X-Force High Flow cat. My exhaust is loud enough as it is, I dont want to have a smell to go with it. lol.

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
