Just wondering if you guys can help me out a little on some things that i'm a little worried about.

The car is a 2003 bugeye WRX impreza (Looks like one of the last built), has recently just had a complete gearbox rebuild and clutch replaced. All problems have occured before and after the rebuild and clutch being replaced. The only mod done is a turbo back exhaust (xforce).

My problems are:

1) In first and second gear I get a very loud 'whirring' sound, its quite high pitch and gets louder as the revs get higher. Having just had the gearbox rebuilt I am pretty sure it can't be the gearbox crying with pain? Could it be a mere 'characteristic'?

2) When I put my foot down to accelerate hardish I get what seems like a creaking sound that sounds like it is coming from the accelerators direction. It lasts for as long as I accelerate with any type of force.

Thanks for anyone that can help out.
