Hey fellas, just a quick question... i want to get my R33 breathing better but unfortunately the R33 stock air box is limited to modifying. Will an R32 stock air box bolt up in an R33? reason being is that the R32 AFM sucks from the lid of the air box allowing the bottom end to be modified where as on the R33 it sucks from the bottom making it unmodifiable... I don’t want to run a POD... I want it to look as stock as possible after that RBT unit checked my car last week... too risky.. Any suggestions?

Regards

Sarkis

I cut a small hole in the front of the lid where cold air comes in from the bonnet and headlight.Then removed the padding from the lid as well and it made no difference to air filter noise.Honestly, I don`t think, from what we have seen on a few dynos,you would need more than that to support 250rwkw.

How much power are you aiming for / have ??

Im running a stock box and have 227 rwkw on a Dynolog Dyno

The other option is if you have a FMIC and run the horrid over the radiator piping, then just get yourself an R33 GTR airbox.... flow more than enough and bolts in.... you just need to mod the outlets to suit 1 AFM..... a good time to replace the squishy intake duct..
