I have recently begun to buld my own PCwhich I'm proud of but my question is.
When I have finished it is going to go in my room upstairs.
Would it be possible to attach a router to the new PC upstairs and connect to the other
router(Main) downstairs?

Its just I want to keep speed up and reduce on wiring the routers are wireless.

It depends on the routers. Most routers only work in infrastructure mode, but some can be configured as a wireless bridge. What are the exact make/models of the routers in question?

Im going to use two routers made by netgear

Netgear WGT624 Wireless Routers

byte rate is around 108bps

The Netgears don't support bridging.

I suggest a Linksys WET54G
