Its always a case of having to spending far more money to increase the power of a n/a engine, I cant fault the abbott system & downpipe for my 2.3t.
I havent really heard of any mods for n/a saabs, what about superchips are they listing anything.
One of the reason I bought my turbo saab was that it was fairly cheap to achieve more power, my wife has my old Audi 2.016V which I spend over !1500 to get a 20bhp increase !
