just got done driving it...drove it for about 5 miles or so most of it on the highway...let me tell you...ill be screwing that car every day if we get it tomorrow...unbelievable how much difference there is between a b18 and a d15...or the difference between a brand new clutch, shorter gears and 4w disc brakes....only problem...everytime i engage the clutch and about 50% of the time i disengaged it...there was a significant click sound...like someone had a tiny hammer and was knocking on the undercarraige towards the central section of the car....2 people at her work said it was because its a new clutch...one was theory....i wouldnt know considering ive never put a new clutch on a used car...any ideas?
