clutch & gearbox unusal sounds?

Curious as in why it makes so much noise and it feels heavy as fk compared to other supras with multi-plates that i have sat in.

 

I've been told by my mechanic the clutch may be FUC#E$. While someone else i know that loves supras & installs clutches. Says its normal for a single plate with a lighten flywheel to have a heavy feel on a clutch & also the sound being normal..

 

What the clutch sounds like,

-Rattling which i hope is the clutch(Jim berry, 3800 lbs clamp pressure). in neutral maybe flywheel rattle (chatter).

-Car feels like its gonna break down stuttering, loud noises coming off 1st gear if not enganged slowly.

-Engages fine, feel like the clutch needs to be adjusted as getting into 3rd gear is hard.. maybe synchro aswell but feel if i push all the way down it doesn't crunch but saying that its like me changing gears slowly which is probably synchros(hope not, but common i read)

-doesn't slip holds power. 430kw single turbo

- slowing down from 3rd to 2nd gear if speed not constant starts hopping abit.

-Apparently normal for clunking into 2nd gear from 1st. on the V161 getrag.

 

Tried to research and look for people with the same description but i haven't heard anyone's car like this exactly. I have a feeling it isnt installed properly but ever since Ive had the vehicle its been like that and no issue besides the sounds. Hasn't gotten louder or anything. Clutch Has less then 5000 kms on it thats for sure

 

Input will be great thanks.

Do you have a aluminium flywheel? If so you will get a loud rattle at idle and most likely when driving. Mine so loud I got rid of it and replaced it with a solid steel one and is much more quieter. There will be a differents in clutch feel between different clutches too, my RPS single plate clutch was heaveir then my single plate compitetion clutch. I would say most of your gear changing issues are down to the clutch not being adjusted properly rather then the synchro. Was the clutch adjusted after about 1300km of driving?

it hasnt been adjusted thats why i brought it to mechanics to get it done but didnt have time for it.But informed me it might need adjusting or replacement. I believe its the clutch but its weird to have 2 guys that know the things to say 2 different things too me. I'm just curious. think the rattling side of things is fine more about the clutch heavy feel(never felt a heavier clutch in my life) and getting into 3rd gear.
