Hello together,
I'm from Switzerland, owning a black Mk2 Mazda 3 MPS since April now.
It has ~136k Kilometers, still first Turbo, and is healthy af! I could readout the complete Service book, the only thing hat has ever been replaced, was a damper from the trunk lid.
A very good sign I think. Preowner was a woman, and she obviously really looked to that car, it's in mint condition.
What I've done/installed so far, is not too much:
- Corksport TIP
- CS SSP and Bushings (hell, that's awesome!)
- CS sexy leather Gear Knob
- Ford Focus ST RMM
- PTFE Seals for intake manifold and throttle body
- removed throttle body from water circuit
- Airbox Mod (being stealth is must-have in Switzerland :/ )
- cleaned the inlet Valves and everything before that with acetone and brushes and lots of air
- installed refurbished injectors (by ASNU Service, with protocoll) and the CS-like stronger seals
- installed button to deactivate SWAS on demand
- rear strut bar, not installed yet
- got Torque pro and a fast obd2 adapter to monitor and logg what I wish to see, such a great app!
What I'm looking forward to:
- Autotech HPFP
- FMS Downpipe with cat
- maybe a bigger/upgraded turbo
- DBA4000 T3 brakediscs + EBC Yellow Stuff (high acceleration demands better deceleration in my eyes)
- Versatune (the reason why I found this Forum)
- new 18" rims, the lighter the better, OZ Ultra Leggera may be a choice (is there other very light ones?)
- and so much more I have to figure out first
I'm planning to reach like 300+ hp, but no monster machine, just bit more spicy than OEM. Yet!
All the best,
Janis
here's the little one!

A few impressions from the valve cleaning/injector replacement

Valves post cleaning, a third clean cycle did follow after shooting this pic, so they were even cleaner than this image suggests

dissolved and extracted dirt:

dirt, blasted out with pressure air, the left partikle is nearly as big as a pea

Injektor, all looked like this
