Yeah i just had a JDM B18C swapped into my car about 4 days ago and it was perfectly fine. On about the 4th day i felt a minor diffrences like it wasant running SUPER smooth like when i got it it had an extremely low and soft putter that no-one could notice but the driver, then i noticed that in any gear my shifter would shake more than normal only when i hit 3000 RPM than anything past or before that was fine. The next day i went to work came back drove it and then i stopped at a stop light and went to put it into 1st gear and it was like i had no clutch i had to force it in hard same with all of the other gears when im stopped. When im driving its hardly noticeable but i can tell its not as easy as when i got the engine. Also some other things are i can pull it out of gear real easy at any RPM and when im stopped and i have to force 1st gear in and its in gear and im still holding down the clutch while its put into 1st gear i will let off the brake and it will start to go forward (this was tested on 10 diffrent flat surfaces). I will be honest i have grinded going into gear about 5 times since i got the car ::to me:: . Please any feedback or opinons are good.

Thanks
