Almost positive it has a walbro 255 in it, and as far as changing the transmission and flywheel im not looking to get that serious with it. I already have a semi built tranny with the shorter final drive,along with the fidanza 8 or 9lb flywheel.
And to be completely honest, i am not sure if the wideband is completely accurate or not since its been on he car for almost 2 years now.
