Good Afternoon all!

 

I am currently located in Spain and owner of a 2001 MK4 Golf GTI 1.8T producing a pathetic 150hp from a KO3s turbo from the factory.

As any other speed freak I would like to get more power (duh)! 
 
Ramair Intake
Forge Turbo Inlet Pipe
Forge Diverter Valve 008
DarksideDevelopements Front Mount Intercooler
Milltek 3 inch decat downpipe 
Milltek catback resonated
A bunch of minor things such as N249, N112, SAI, EGR, PCV delete
 
Car produces 215hp with 270 pound feet of torque (could've gone for higher figures but I figured to chill as I do not have a uprated fuel pump)
 
I have been looking online and found BBT (beachbuggyturbos) and TTE (theturboengineers) for ko3s hybrids. I was thinking of going ko4 but then I was like mweh. Or I dont know, should I get a KO4? BBT offers the K280 (I assume it would be safer to choose that compared to the K300) but can anyone chime in on what setups are good? I am kind of in the dark here as my knowledge is quite limited.
 
I am aiming for over 250-280hp, I don't want crazy stoopid figures as I want reliability too!
 
I am looking for a hybrid turbo that will: 
Not need whole engine to be rebuilt (new piston rods, valve springs, bearings etc.)
Can be somewhat reliable
Is somewhat a Plug and Play function  
Will not cost an arm and a leg
 
What other mods would I need? I gathered from online forums Injectors, Fuel pump, Exhaust manifold. What else? What CC injectors?
 
Any information at all is very much appreciated!
 
Cheers
Milt
