I'm looking to run a blow through MAF when I return to the states in a few days to go along with a Perrin GT30R turbo. I need to know what size reducers (internal diameter) to use with a TurboXS shorty intake as the MAF tube and TurboXS intercooler piping. I've searched quite a bit and found almost nothing on dimensions. So far it looks like ~ 3" OD for the MAF pipe and 2.5" OD for the intercooler piping. Unfortunately I'm overseas so I can't just go out and measure.

I'm want to use the shorty intake as the MAF tube because the diameter is close to stock for ease of tuning. I plan on using MAF for low to mid loads and SD around where the MAF is maxed.

Going out on business for a couple days. I'll probably take my chances and order the 3" to 2.5" reducers when I get back.
