In order to bore out the 1.9 to 2.1L, you need to physically remove metal from the cylinder to make the volume bigger. You will need a larger piston and different components inside to add stroke or bore. It's not an easy task and I don't think you could do it without a large expense and sending it to a professional. It's just not easy. I don't see why it would be a problem with FI though as long as compression is lowered (since FI will add more stress to the motor and increasing cylinder volume weakens side walls). You will basically max out your motor with the DASC unless you add nitrous or water/alcohol injection (Which are both inherently risky). |
