Improve performance

[mark white]

Good evening everyone 
I’m sorry I haven’t been on here for a while, I’ve been finishing the rebuildi on my 280 Capri. 
Well I’ve just used my 1987 S4 Manual for the first time in about 5 months. 
I’d like to improve the gear change as it’s not at smooth as I think it should be, any ideas?
Also how can I improve the performance of the car? It was an auto and I converted her about 6 years ago

Many thanks Mark from Eastbourne
