Any NA car is going to be fine with a walbro 255 and 600's. I am running 533whp on a 340 and 1000cc injectors.
However
Walbro 255 = $75
Install kit = $75
600cc's = $500
Uprev = $500
Tune= $500
$1650 for 10 HP?
Not to mention you will be glued to certain stations and you can never take a decent road trip unless E85 is everywhere in the area which in most cases isn't.
The only way I can see this making sense is if you are running without cats and the smell is bothering you. But it had better bother the **** out of you for that cost.
