It's all the driver buddy... I ran 13.5 stock with the ITR motor in a heavier 99-00 SI coupe than the actual Type R chasis. You'll need slicks or a good set of drag radials to accomplish your goal, though its very duable... My mods where as listed below...

* Distributor Timing set at 18 degree's
* AEM Cold Air Intake
* Apexi WS Exhaust
* Falken Azenis (Ran 13.8's... 17psi in front tires, 45psi in rears Launching @ 5500rpms)
* M/T 22x8x15 Slicks (Ran 13.5... 10psi in fronts, 45 in rears Launching @ 7800rpms)

13's are possible with the motor being practically stock with the right suspension tweaks and the correct driver. I'm not saying I'm the best driver out there, though you'll really need to drive the car hard and aggressively to achieve these times... Good Luck, if you have adjustable suspension, lower and soften the front while hardning and lifting the rear to keep the majority weight on the front tires..
