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!!

 

only mods will be about a fuel pump, chip and exhaust which will take you up too about 280-300hp... for about 500-1k

over the 300hp will mean full management change and turbo change and inj change looking about £1-3k for that..

HTH
