Whoops forgot to check this. Yes it's actually going on a Celica, we use the same basic MAF as Subarus GD WRX/STI but with a lower resolution. Once you go to a 3" intake pipe and supercharged the standard MAF maxes out.

I didn't realise this forum was linked to my old email, someone on here has PMed me in regards to a 06' STI item so the search is over.

Thanks guys.
