Please help before i give up and sell..
Im realy at wits end now with this car. ive only owned it for just over a month (no warranty before anyone asks 
) so far i have replaced the rear diff, rear callipers and rear screen.
The latest is the car wont go into 1st gear and clunks (not grinds) into 2nd.
to put the car into first is to realy push as hard as you can but im afraid of damaging it so i have to put it into 3rd and then into first. Then when going from 1st to 2nd it clunks into gear.
So far i have changed the gearbox oil for Redline 75w 90 and also bled the cluth and replaced the clutch fluid (i thought maybe clutch wasnt engaging properly as thats what it felt like)
I had thought it might be the syncros but its not grinding at all the gearbox just feels clunky and rough
at this stage if i have to fork out for something to be replaced in the gearbox i think i might have to give up and sell as this car is costing me a fortune
Any help or suggestions greatly appreciated.

Can you get into all gears without any problem with the car parked, engine off and parking brake off?
If you can, it MAY be a dragging clutch disk.
Either because of the clutch not fully disengaging or not enough lubrication (or build-up "rust" or clutch dust?) on the clutch disk splines.
Do most of your shifting difficulties happen when the gearbox is cold?
If so.. then I guess you have to live with it.
Its normal. (depending on the oil you use)
The "clunk" into 2nd is something I have too, especially if I shift to 2nd at low speeds.
Why did you pick the Redline 75W-90 oil?
On the Redline website they say its more of a differential gear oil.
Redline also has the 75W-90 NS oil, to:
Honda MTF is also a good product, especially if you can get the updated stuff.
Replacing the clutch fluid (with brake fluid
) involves bleeding the system.
Doing that by pumping the clutch pedal is a good way of doing that but MAY not get all the trapped air out of your slave.
(IF it was there to begin with - see dragging clutch remark)
A gravity bleed with the slave off the transmission with the slave piston pushed all the way back in is. (Billman
)
Doing that will also allow you to polish that push-rod to get a smooth clutch pedal feeling. (dbzerk )
Don't give up on your S2000!
(at least not yet!
)

This GL-5-type geal oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.

I also have a slight clunk when shifting, especially when cold but nothing that seems out of the ordinary. It still feels much better than most other manual transmissions I've driven. I'm about to replace the trans fluid with the Honda MTF. 75w90 is diff fluid (at least what I'll be using in the diff). Transmission fluid is lighter weight I think, which I would believe is why it says in the manual you can use regular engine oil for the transmission in a pinch.

)with the engine off clutch pressed in the gear change is like butter, perfectly smooth!
i brought it down to a local gear box specialist there a few mins ago and he seems to think it might be the clutch as well and not the box at all.
his reasons its most likely the clutch and not the box;
1. It goes through the gears perfect with the engine off
2. once it gets into 1st with the engine running and the clutch still pressed in it goes through the gears perfect including 1st and smoothly into second.
does this sound right to people?
Im also going to change the gear oil as well so what do people recomend most. I have tried getting my hands on Honda MTF but Honda wont sell it to me as they only get it in large drums for doing services and dont sell it seperatley
Ive seen threads recomending Mobil 1 75w 90 how does this differ from the Redline 75w90?
One garage i went to that i use regularly and trust use Motul 75w 140 in the likes of DC2 Integra Type R's and Civic Type R's both EK9's and EP3's etc so they think it should be ok for the S2K?

Just thinking out loud here: suppose the clutch disk is sticking a bit, when you get it into 1st, that "shock" makes the disk move a little over its splines, just enough to not be in forced contact with either the flywheel or the pressure plate and not stick anymore, making it easy to select all the other gears.
IMO that 75W-140 is way to thick for the S2k gearbox.
Why don't you go to that Honda dealer with your own empty (and clean) 5 liter container and ask (TELL! ) them to put 2 (or 4 if you want to flush once) liters of MTF in there, pay your
