But go ahead, waste your money

Just don't confuse this N/A platform for one that greatly benefits from induction modifications like with pre-turbo intake modifications on an Evo, STi, Audi TT/S4, whatever...

SCSI is right we were going to stay with stock sized MAFs but then revised our plans since we are looking at beyound 1000rwhp. look at it this way... if the stock MAFs are good for 500hp turbo cars you arent going to need bigger ones on a N/A car... Tunning will provide the best bang for the buck and with GTM's 1st unit coming out this month you better believe your gonna want some!

And I want some!

Correct me if I'm wrong, but doesn't every forced induction kit for the 370Z place the MAF sensor post-turbo? They're measuring pressurized airflow then and thus have a greater capacity to measure mass flow, depending on exactly how much boost pressure you're running.

With Evo's, STi's and other factory turbo cars, the MAF is positioned pre-turbo so they are measuring air at atmospheric pressure; and that's also why we often need to upgrade MAF housings to accommodate for larger-than-stock turbo setups.

So, for the 370Z, it would only make sense to upgrade the MAF housings if you were looking to make more than 450-500 bhp N/A or 900-1000 bhp force inducted, roughly speaking.
