The car leaves for MPS within the next few days, needless to say I am excited!

Hi all, I am quite new to the site but have been a member on for quite some time now. Thought I would migrate my build over here so....

To give you a little background, I bought the car new back in early 2009, I had done a few modifcations to the car, stage 2 etc and loved every minute of it. A month or so ago the car spun a rod bearing and I was quite annoyed to say the least! Although as I am not the kind of person to sulk about something I thought I would do a project and make the car something I would really enjoy!

So the car currently has:

Perrin TBE,

BC Coilovers,


Perrin Intake,

SS and bushings,

Sport Grille, STI V-spec lip and other cosmetics etc

Now with the above in mind, this is the parts list I have partly acrued, some is either shipping or I have not made a final decision on:

Raw Stage 3 Forged shortblock 

P&L High Flow oil pump

Blouch DOM 3 XTR

APS 70mm Inlet and Intake

ID 1000cc Injectors

Walbro 255lph

FR UEL headers and Uppipe

Killer Bee oil pan / pu combo

Exedy stage 2 clutch

ProcessWest TMIC (sleeper style )

I will also be adding Rota Torque 18x9.5 +38 et 

(cant decide on what colour to powdercoat them yet though, suggestions??)

I think thats everything so far, i will be keeping this thread updated regularly and I am picture happy. 

I am also willing to answer any questions and I am open to suggestions, however this is a build thread, if you feel the need to bash, do it somewhere else.

I may even ask stupid questions from time to time but I am here to learn!
