You are not gonna LOSE anything by going 58mm over he 52mm. Even if your motor doesn't NEED the additional 6mm, you will gain a snappier throttle because you are letting more air in quicker everytime you punch the gas. I know my car did.

And I doubt Lloyd Elliot says to stay away from the 58mm, probably just recommends something over stock, the minimum being 52mm.

And when the 52 and the 58 are nearly the same price, why would anyone get the 52mm?

Because they are gonna lose torque? yeah right.

Stock TB is twin 48mm and the stock intake openings are 52mm. It takes 5 minutes to open them up to 58mm with the intake on the car. There is a very good how to out there somewhere.

ill be aiming for a 400+ h/c and full bolton car, should i do stock intake with 52mm tb or ported intake to 58mm with 52mm tb? or 58mm and 58mm? what would be the best setup.

58mmTB and just open up the holes in the intake with a dremel.

There is an awesome how-to out there and any idiot can do it very easily.

The stock intake and throttle body will be just fine at that power level. I would suggest that your money would be better spent on something else.

Air foils dont help, no way to tell unless you measure it. Pull the TB and check with a digital caliper

they dont provide anything noticeable. they might not even do anything for flow. i just got one back in the day cuz it was free from my friend who swapped a BBK onto his car. it made my stocker look way better.

dont even have to pull it just use a caliper - go up to autozone and ask to barrow theirs (i know i have one at my store)
