Ladies and Gents,
Been trying to work through a sudden loss of acceleration on the S2 R33 GTS25T over 3000rpm or so at WOT. I can baby it up to about 4500rpm but it loses its go about there also. 99% sure my oem cat is done.
OEM fuel filter, OEM Coils (x6), serious AAC cleaning were done chasing a solution. OEM MAF, NGK plugs pregapped to 1.1, coil pack harness were previously done. Cleaning my throttle body in the morning, and giving my ECU a reset. I can hear a ticking/whoosy whoosy noise going through my cat at idle. Plan on popping that off tomorrow too and checking it out. Pretty sure its gone.
My big question is whats the OEM cat cell count? I dont have the funds to jump to a tuner/tune and cat at the moment. Figure a Venom 400 cell should get me running well for a bit until I get some supporting mods and a tune. Any suggestions? Again, car is entirely stock, unless you count some aftermarket brake pads 😅 Many thanks.
