O.P. you can look into BMR suspension upgrades to put more of your stock power to the ground. Trailing arms and rear cradle brace will make a noticeable improvement taking off from an manual trans. i recently put a green filter and cut an opening on the side of stock airbox, per Pray's testing on an older thread and it has helped with throttle response nicely.
That's 4 total upgrades for right at $ 400 altogether.
(Lower & upper trailing arms, rear cradle brace, green filter)
After that, like everyone agrees, take it to the track & you will be smiling.
