Are these dimensions different on non-STI models or is it different for JDM? What dimensions are the MAF / turbo inlet on non-STI models?


cheers,

sti v4 has an 80mm maf pretty sure non sti has a 70mm maf

 

cheers for the fast reply!


any idea on turbo inlet size? are they both the same?

 

Yup should be the same, been a while since I looked at standard inlets but from memory think it is 58mm

 

Thanks again. I'll have a measure tonight after work. It's amazing how different every Subaru is.
I've read lots of differing measurements everywhere ranging from 90mm on 98 WRX's to 84mm on 22b's etc ... hard to know without getting the ruler out.


I had my pipe off yesterday but I cant for the life of me remember the exact figures. I'm sure my MAF was around 80 maybe slightly more , and my turbo inlet was over 70.... agh!

 

you've set me off now had a good search around these are defo correct lol

Ahhh that combines the two OEM pipes into one solution; the flexi to the MAF and the turbo inlet. I'm on about only half of that!! (the flexi to the MAF from the turbo inlet pipe)

 

Just this part?

awesome. got there in the end ! thanks

 

For anyone that cares (and after scouring many posts online with different figures I feel some do!)
I measured the MAF to turbo inlet hose yesterday.
The inside diameter connecting to MAF is 89 mm, and the inside diameter connecting to the turbo inlet hose is 76mm. This is on a V4 JDM STI.
