just soupe it all up and maybe adjust the transmission into 25 and maybe do it in b-spec
also...

I had the same problem but bro help i was missing a turbo piece. and then when u could do
is use B-SPEC there a race or 2 that u will have to do

I used the Speedster Turbo, Bought everything including all the racing tires I had my
tranny set at 9 as you will just max out on the straight. I had my brakes adjusted on the
rear to 6 and used the racing soft (R4). I got 179 A-spec points, Also you have to use
your Nitrus sparingly your tranny settings will vary from 7 to 9 according to the 5
races. It is vary tedious but I finally did it
