Hi guys, i'm grant.
I just px my 300bhp sunny gti-r for a standard cosworth, now i knew it would be slower, but not by that much.
It just feels so slow


I like the car and what it is but i need more boost and power.
Its a small turbo, can somebody recomend me a link to a decent tuning guide, take more boost, what actuator, chip, will i need injectors? What sort of turbo back exhaust is a good fit, esspecially round the bumper?
I'm looking for about 320 bhp or what i can get without changine the turbo just yet.
Thanks!!
