Don't be confussed kelv It makes sence to me.....
Rs500's have a turbo on them able to push 550bhp and they only run 220bhp standard?
If I have a turbo good for 600Bhp and run 500Bhp I think it should work well enough.
you don't have to be Finish, danish or swedish to run a large turbo
HOMOLOGATION
look it up...
I ran a GT35.... great for Top end power and with a PROPER 6 speed dogbox to keep it on the boil and some solid lifters OR a bigger capacity engine then yes they work well for a trackcar
On a standard 2litre YB the GT30 is a MUCH MUCH more driveable and FUN Turbo in my experience on both road and track. Its also made the Sierra a FASTER track car in my opinion.... more power for more of the time! more driveable and controlable. Just Suits a 2.0 YB alot better in my experience.
I love my GT30 and should have switched years ago!
