The removal of the stock manifolds and elimination of the AFM will result in more power with porting. Stock NA manifolds are also terrible for 99% of porting. Carb's don't win compared to an aftermarket EMS and manifolds, but if the entire point is to gain more horsepower for cheap, then the carb isn't a half bad solution. If the owner is ready to give up alot of the conveinence involved in an EFI setup.

carb setups for FC's arent exactly cheap, either. if you took the same carb manifold and attached individual throttle bodies instead of a carb and used a cheap standalone such as megasquirt you would get better results for around the same price.

A good carb setup can cost only $800 dollars installed in a car by nearly any shop (considering a carb doesn't take lot of mechanical knowledge to install and there is ALWAYS someone that can tune it locally). Look at a good EMS (Microtech $800ish) and the only off the shelf aftermarket throttle body (Tweakit $600ish) (I'm not counting the one that never has proof of existence other then by the seller of the products) and the Holley manifold ($250) that is needed to install it. Let's add in injectors from a TII ($50 or so x 4 = $200) and you have yourself a VERY expensive NA project. Let's factor in a wideband and dyno time for both ($50 per run) which just adds to the cost
And I don't really advertise Megasquirt, it's still unproven to me (sorry MuThaiboxer). I haven't seen or heard of anyone making great power with it or really anything other then heresay. The only personal experience I have had weren't that great. But still it DOES come out more expensive. BTW, can you use any EMS that comes along even? I know that carb tuning is about one of the most universal things. Anyone can tune one locally.
But for the limited streetable (it's subjective) power potential out of an NA, a CARB isn't the worst idea. That and everyone that doesn't have $600 dollars worth of cash to dump into just throttle bodies.
Finally, just read my quote in the signature.

how many times is everybody on this forum going to have this same damn argument haha. it never gets solved. nobody is ever going to give in. each side has their points and its just gonna go back and forth forever. if you want to build urself a good n/a motor just go here and read: https://www.rx7club.com/2nd-gen-archive-72/how-make-beefy-n-need-your-recommendations-31410/ end of story. enough with this carb/efi debate. its old

Great, another carburetor vs. EFI debate. It's not like this has not been rehashed 10,000 times or anything.
Still, I think I should contribute. So here goes:
