George1943 Posted October 7, 2020 Share Posted October 7, 2020 Does anyone know the approximate HP difference between a '95 fuel injected EJ22 and one that has been converted to a Weber and an Escort distributor? Link to comment Share on other sites More sharing options...

Expand Tuned correctly it will be the same. Tuning an EFI car is much easier. If you're already using a stock ECU that is correct for the application, no tuning needed.

George1943 Posted October 7, 2020 Author Share Posted October 7, 2020 Thanks for the response. Good to know. That is my 'plan B', IF I ever get around to making the swap. Link to comment Share on other sites More sharing options...

dfoyl Posted October 9, 2020 Share Posted October 9, 2020 I would love to see evidence that a single or twin barrel carb can get the same performance as a MPFI setup. Carb vs SPFI I'd agree, MPFI I doubt very much. Even Subaru's own EA82 shows a marked improvement from carb to MPFI (9kW, minus what was gained from increasing the C/R).

carfreak85 Posted October 9, 2020 Share Posted October 9, 2020 Not Subaru engines, but here's one version of the answer: Link to comment Share on other sites More sharing options...

Also the power gain could be entirely artificial to justify the increased cost. Link to comment Share on other sites More sharing options...
