l am building a 300 h.p. NA EJ253 and was wondering if anyone knows of any EFl to Carb swaps. Or know of a company or person that could give me a lot of info about it. Thank you.
It is not an STi. The STi never came with an EJ253. It comes with the EJ257. The engine l have is pieced together over a period of time. l am thinking Carb due to the sheer mechanically reliability and tune ability.

Why would you want to change your EF l to a carb?
You have more gains with EFI. Mileage and power.

Umm, l am dumbfounded by this. Why would you want to go N/A on an STi engine? The STi comes with 300 at the crank, a new exhaust and some decent engine management is all you would need to get that 300 at the wheels

ummmm why would u do that?? Just get the car tuned and you will get 300 at the wheels with just a few mods. Going with carb does nothing. Remmember its not a muscle car.
