58mm TURBO INTAKE... OR 76mm ???
At what sort of power levels, etc. does a 76mm turbo intake become NECESSARY, instead of an OEM-sized 58mm one?

Cheers. Yeah, I would've said 450-500 as an educated guess.

Lateral offer them in
either 58 or 76mm... so not all MDs out there will have 76mm intakes.

Cool
Looks like a 76mm is only
really required for big power or, say, to produce the goods on a 2.5....

The 2.5 can only consume so much air.... 2.0 just needs more revs to match it !

I was advised by Mark to go with a 58mm intake on a 321T (which will be running around the 450bhp mark). Can't remember what reason he gave, but it made perfect sense at the time.

I'm running the 58mm on mine with the standard intake pipe.

I read somewhere that unless absolutely necessary for the horsepower aimed for, then don't run a 76mm intake, as it could promote compressor surge.
So only go 76mm if absolutely required.

That's right - 76mm only required for BIIIG power it seems.
