do efi 4age backfire?

[kpretro84]

Hi there i have a few things on my mind. i just wired a smallport running Bigport electronics engine runs great starts idles 1000 rpm revs up all the way 7000 rpm with blue top ecu dizzy injectors and sensors but the engine is smallport and i want it to backfire like the carby 4ages do up in the revs its not doing that? does someone on here with a 4age thats efi and behaves like a carby? backfires are cool when over reving.

2nd thing The engine is in a Starlet and i have a picture there blue Kp61 the old owner of that car has swapped it for an ae86 does anyone know where that front spoiler lip came off? or does someone know how i can get in contact with the old owner of the blue kp.

Lastly my engine that i just started its a rebuild fresh engine no miles/kmz on it. How should i run it in?

Push Buttons soon guys
Many thanks
