Can I put a fuel-injected engine into a car that currently has a carburetor?

st Gen CRX FAQ's - Hondaswap
Fuel injection requires a pressurized fuel system that the carburetored cars do not have. You will need to change the fuel system and a large portion of the wiring harness to put a fuel injected engine in your car.

How can I make more power in my fuel-injected engine?

st Gen CRX FAQ's - Hondaswap
If you get more air and fuel into the engine, the engine will make more power. To supply the "more fuel" I put in a set of 86-87 Integra injectors that I had cleaned and balanced. To get the "more air" I built a better breathing throttle body out of a stock, twin choke throttle body. I opened the throat of the primary choke from 20mm to 26mm and I also smoothed the path to both chokes.

Will my stroker consume more fuel than a 4.0L engine?

Frequently Asked Questions
Since you're adding displacement (~15%) to the engine, there's no such thing as a free lunch. You need more fuel to feed a bigger fire. That said, a stroker can match a 4.0L engine's fuel consumption during highway cruising but you can expect your mpg to drop 2-3% in mixed driving conditions. That's only a small price to pay considering the extra performance on hand.

Can I tune the engine to use another octane fuel?

In general, modern engine management systems will compensate for fuel octane, and once you have satisfied the optimum octane requirement, you are at the optimum overall performance area of the engine map. Tuning changes to obtain more power will probably adversely affect both fuel economy and emissions. Unless you have access to good diagnostic equipment that can ensure regulatory limits are complied with, it is likely that adjustments may be regarded as illegal tampering by local authorities.
