Three questions. 1. Where is the screw to adjust the throttle bodies on the s4 TII throttle body? Because I've got a power fc installed and the idle won't stop surging. It's getting too much air at idle and I cant screw in the bac valve anymore. 2. What are the measurements for big shafts and normal shafts in turbo's. 3. With good tuning and a streetport how much power should I be able to make with a 60mm/80mm turbo on the compressor side matched with the stock hotside and a p trim wheel in it? Also how should spool be? Another question, is there anywhere where I can buy a flange for an s5 turbo? Any questions you can answer would be appriciated. Thanks guys and may the rotor gods forever shine on you.

 

The S5 turbo flange is Mazda specific and only mates with the S5 Manifold.

 

you need to use an evap smoke machine on your intake to identify all the leaks. any (GOOD) auto shop has one and could charge as little as 45 dollars to run it and let you see the leaks to fix them.

 

I know it's mazda only but I'm asking if mazda or racing beat sells the flange.

 

i think i saw them on flea bay once.

 

any body else? How much power should could I make with a 60mm/80mm turbo? And how fast should spool be with a 1.0ar divided housing and a p trim wheel?
