Hi guys.This forum is really awesome so i figured it would be a nice place to keep track of what i do to my ST.

I have no clue if it is an st2 or st3,maybe somebody can identify it for me lol.

Quick summary...I bought it in February with 120 000km on the clock.It was completely stock besides a decat.

Mods i have done so far are:
-Resonator delete
-Motorcade bottom mount intake
-ARC coilovers
-Polished the headlights
-Full LED package

Mods i have on order
-Maxton lip
-RS wing
-Rogue performance 76mm downpipe
-Pumaspeed BOV

I plan to have the block mod,waterpump and cambelt done towards the end of May.

I'll just post a few random pics now.One a pic of what i used to drive before getting my st.Another is of my buddys st.His dad has a 225 and a 250 so they've been really helpful.

So after many many days of reading and researching,it would seem that my GFB dv+ is the most likely cause of the issues I've been having.The spring seems to have way too much preload which is causing the insane compressor surge and poor boost "delivery".

I will loosen it and see what happens but I think the best solution would be to just get a forge recirc and be done with it.I should have just stuck to the tried and tested from the start lol

Heh, it is exactly what I have noticed while playing with GFB dv+.
If you want the noise, you have to tighten the screw which will open up the valve ever so slightly and you feel like the car is not pulling as hard. If you want maximum performance you have to trade in the sound. I say the same, better a simple recirc valve without all the settings.

Feeling much better thank you...Had a respiratory tract infection.

Did some ordering while I was recovering.Got a set of 15mm spacers.Hoping these will help with my rubbing issue.Also ordered a forge recirc as I have no desire to fiddle around with the GFB dv+ to get it set right.Ordered a new coolant bottle,cap and a toe eye cover.Really excited to get it back up and running again!

Replaced the expansion bottle and cap and that seemed to have fixed my coolant loss.I dropped it off at a mechanic this morning to have the recirc fitted aswell as have him run a pressure test just to make sure.He also fitted the front spacers back and did a quick check over.

I will need to go disks and pads ASAP and the control arm bushes are worn.I also have a few buckled wheels lol.

Picked up the car today and boost is super smooth so I guess it was the GFB that was not installed correctly.I am not happy with the front spacers at all.The center bore isn't what I requested so the studs are taking the weight and the nuts that were supplied have heads that are far too wide.I will be be removing them tomorrow.

Good day gents...car was put on the back burner during the festive season but I'm feeling motivated again.Fitted a new battery today and got it washed after sitting for almost a month.

It will be going away to get the radiator replaced,actuator spring changed and hopefully they control arm bushes.The new wheels should be going on soon too.I have all the bulbs for the new headlights as well all interior bulbs.

Tailights are absolutely hideous and will need replacing soon.
