are there any fuel injection Complete systems (comes with intake an stuff) that will fit in a stock hood? everything in my car is stock an i want to upgrade but keep the stock hood. there has been other post about the space needed but they talk about carburetors not fuel injections

 

As long as you stick to low-rise intake manifolds, many of the performance parts will fit under the stock hood without issue. Its only when you get into running high rise intakes that it becomes an issue as it puts the TBI/Carb up much higher than stock, leaving little room for aircleaners and such.
