Dear 930 friends,
my K27-7200 needs a rebuilt since I have a little smoke at 1000 rpm so I was thinking of slightly increasing the turbo pressure after the rebuilt for more sensations.
I searched for a 0,9 bar boost spring but can't find one. I have a 1987 stock engine with 160 000 kms on the clock, perfectly functioning.
What do you think of a 1 bar boost spring (stock IC)?
I thought of using an ajustable turbo pressure device but I don't like this solution (risks).
I still have the stock wastegate.
Any advices are welcome
thanks
