I am looking into purchasing a car that has a big bore kit on a 2.0 engine that has been switched from fuel injection to dual webbers. Does anybody know the difference in horsepower, and any concerns with this mod?
Thanks in advance

depends entirely upon the way the big bore kit was installed, and with what parts? Is it just a 96mm big bore? that's only a 2056.

Unless the motor has a carb cam or a Jake Raby combo you will get a whopping 15mpg vs the 28mpg with the FI. You will also have less torque.

the bore and carbs won't do you any good unless you also got a more agressive cam to go with the carbs.

if that is the case, you will have more HP than stock and if setup right your gas-milage won't be too bad.

like jake likes to say, it's all in the combo!

PS: i think what i'm trying to say is: we need more details/specs on the motor before anybody can say anything definative ...

All those "Combo" pieces are now available!
