ok guys need some help i got a r32 with rb25det an manual out of a r33 series 2, i just got the car few days ago an over couple days driving it was getting harder to select gears. An now its gotten really bad the clutch pedal goes all the way to the floor an comes back up no problem, when i put the clutch pedal in an go to select any gear also reverse it wont go in without alot of force an will cr...unch sometimes, especially when starting it cold have to wait for car to warm up properly before any chance of it selecting a gear. Once ive gotten it in gear an start driving its same issue hard to select gears an always crunches 4th, my clutch doesnt slip at all an from what ive read up they have hydraulic clutch so can anyone please urgently give me advice on what the problem is... If anyone a mechanic or knows what your doing would be much appreciated if you came to look at it thanks [phone removed]
