Heres a little question for you Don. How can I change my 3L 250 EFI into a 300 EFI? Is it just new injectors and or ECM? What else would be involved? I know I should be plenty happy with this 250 but was just daydreaming (lol).![]()
Thanks,
DeSean

Hmmmnnnn.... a 300 EFI?
Talk with Eric Simon.... he offers plenty of "goodies" for your engine.![]()
Or.... install the four-bolt upgrade kit. Four 1/2" bolts, nuts and washers (and inside the box with these bolts comes a 300XS).![]()

You can get your 250 EFI to run pretty good with some upgrades. Like Don mentioned, call Eric Simon (Simon Motorsports) and talk to him. He's a great guy that doesn't throw down any BS and always wants to make the customer happy. There are also other in the 3.0L upgarde business like Tony Bucato who makes the SVS intake that I run on mine. My 250 EFI runs pretty damm good after some mods, est. HP after mod's on the 250 were about 280 HP. Grant you it's not 300+HP but it's very reliable and for the money spent, well worth it, enough torque to swing a 32P wheel.............nuf said![]()

I'm thinking those 4 bolts would be pretty darn expensive.......
