I'm thinking of my next project.This 48 does good.But I'm thinking of a series 4 EFI conversion(They still have a manual OMP system and less wiring).Is the series 4 EFI better than a Carb setup for power?

i think a 48ida would make more peak power, but the s4 efi will be better on the low end

I would assume that ultimatly The EFI will make more power, but requires alot of computer tunning. With the Weber its straight forward and you dont need a bunch of computer equipment.

I will choose carby over EFI....

Thanks mike.I remember that page now.He says if the carb was setup right the power would be about the same.I think I might buid my next car with another carbed 13b 6-port but with series 5 rotors and housings.I already have a good SE eccentric shaft and all the swap parts from my old engine. https://www.nopistons.com/forums/pub...#>/biggrin.png

cool, ive got one like that for my black se, when that motor gives up



mike

I would choose carby cause it looks cool and cause it is way simpler than EFI to setup...

yah, ive been thinking about a 48ida for christmas



mike

Yes it sounds quite nice...I should surprise myself and get one....

yes that sounds lovely



mike

No If I could just rob a bank.......

My dellorto setup makes the engine bay so clean looking.I might pull the OMP out for a cleaner look.After this gas in the tank gets burned. https://www.nopistons.com/forums/pub...#>/biggrin.png I can't wait for spring to put up some new pics with a cleaner engine bay.And the mazdatrix front on it. :yum:

if you really want power, go to efi, yes you need computer and sensor and all that kind of **** but you dont have to adjust it every month, and dont have alot of cold starting problem, and you dont have to rebuilt anything like the carbs. you set a program and that it it give you more power, fuel mileage and reliability.

Googlefight tells no lie.. Carb all the way Baby..

i prefer carb, i´ve a weber 44 idf and works fine

I'm going to agree with 75 repu on this one.And I have my 83 to use for the cold if I need it.You don't need to adjust carbs every month with for your information.
