It would be very hard/expensive to make it an 11sec daily driver. fwd trannies are very weak and 3rd gear is prone to failure around 250whp or so. it would take atleast mid 300whp to get into the 11's, but again you are looking at breaking the tranny. Unfortunately your only real opinion would be getting a PAR gearset that is good for about 450hp with the synchro set and 600hp in the straight cut gears (which are not reccomended for a street car). The 450hp set alone is just under $3000 for just the gear stack. Unless someone else comes out with different gears that is going to be the only way the tranny will be reliable at a powerlevel required to hit 11's. You should really search
