welcome along man.
1stly most people will say you need to spend load of cash to do 13s. not tru.
Its all about car set up and having the right amount of balance in your set up. power, suspension, grip, and a good drive
I personally would start off buy going to a td04l turbo set up or similar size garret turbocharger. this will give you an instant power increase even on only 8-10psi. Going for one of these turbos allows for later expansion, possibility of bolting a larger version of your current turbo to the same manifold etc.
You will need things like the following
turbo
exhaust manifold
intercooler piping
full down pipe and exhaust system
aftermarket turbo actuator or an external wastegate
electronic boost controller makes huge differences in boost response and power levels being able to attain stable boost levels
small radiator
increased fueling an aftermarket ecu if you want to run above 12psi (average boost level at which the stock fueling runs out of juice)
Suspension
coilover's make a huge difference. setting the rears shocks damper, springs to rock hard, and lifting the rear an inch or two higher than the front helps with weight transfer on launch.
Tyres
semi slicks of dot radial drag tyres will help you sustain a good consistent 60ft time which is the biggest challenge in any FWD car and makes the difference between a 14sec run and a 13sec run.
Drive line
you need a good clutch for drag racing, something with loads of clamp and a fast engaging time.
short shifter helps loads
and last but not least and most important of all is an aftermarket LSD!!!! this is the key
the rest is down to dialing in the car at the track getting set time and working out what achieves the best results.
launch rpm
shift points
tyre pressure
fast shifting
etc etc it all makes a difference to your ET!
good luck !!
