Re: EFI vs carb

i have had 3 carby xf 3 speeds and i changed them al to a 4 speed borg warner box and they have at least 25% more power with a manual on them but as for efi this is my first one i have owned (current one i have) the efi has more power on tap especially after 2250 RPM they get a power boost.

i am changing it to a T50D box which is the 5 speed manual.

the carby auto got 76 RWHP with 2 inch sports exhaust
the carby manual got 97 RWHP with 2 inch sports exhaust
the efi auto got 91 RWHP @3900 RPM
(these are all stock cars )

so if that helps in your decisions on what to do. good luck.

Re: EFI vs carb

I'd go for EFI too.

I remember reading somewhere, either a website or magazine, where the EFI 250 matched the last of the 302s in power, and came pretty close with torque. God-damn I hate their standard engine/exhaust note though, oink oink.
